A word of warning:
If the remote switch is used to directly select the new bank,
you will be placing 13.8V on pin 19 of IC8, which is too high.
Instead, make a voltage divider by putting a 68k resistor between
the output of the remote switch and pin 19, and a 39k resistor
between pin 19 and ground.

Subject: EPROM erasers
In regard to this discussion about eprom erasers and eye damage, the
question comes to me and that is just what is it with ultraviolet light
that is so bad with your eyes? Does it screw up the retna? The corona? What
does damage to what? We had a germacidal lamp at the kindergarten school I
went to thirty plus years ago and I remember looking at it (it was this
deep purple glow). I can still see now. Again, what's the big deal? People
have black lights in bars and living rooms and I never hear of anyone going
blind.

Subject: NASA Prediction Bulletins
The most current orbital elements from the NASA Prediction Bulletins are
carried on the Celestial RCP/M, (512) 892-4180, and are updated several times
weekly. As a service to the amateur satellite community, the most current of
these elements are uploaded weekly to rec.ham-radio. This week's elements are
provided below. The Celestial RCP/M may be accessed 24 hours/day at 300,
1200, or 2400 baud using 8 data bits, 1 stop bit, no parity.

Subject: Signal Splitters
I opened one of those 75-ohm coax TV signal splitters and I saw the
darnedest thing. The input split into two wires, one wire went into
one end of a ferrite bead, came out and when to the output #1. The
other input wire went into the opposite end of the ferrite bead and
came out to output #2.
Well I know that an equal current is going to be flowing both directions
through the ferrite bead. Shouldn't the inductances cancel? If
there is no inductance what is the bead doing? If it isn't doing
anything how can it prevent reflections due to the 75-ohm to
37.5 ohm split effect?

Subject: Soviets continue microwave zapping of US embassy
x
According to an Associated Press story in the March 4
Beacon News, the Soviet Union continues to bombard the
U. S. embassy in Moscow with microwave signals.
The 9-11 GHz and 5-6 GHz signals are typically 0.01
microwatt per square centimeter inside the embassy buil-
ding, and ten times as strong outside.
The State Department protested the tactic over 4 years
ago. Current levels are lower than those in 1980, when
the microwave signals were measured at over 1.0
microwatts per square meter.
In the past, there was speculation that the Soviet radio
waves were either an attempt to induce psychological and
behavior changes among U. S. personnel, or had something
to do with bugging. [The more likely purpose is to use
the beams to excite eavesdropping devices planted within
the embassy - BP]

Subject: Tiny little TNC?
I saw the following in an AMSAT news bulletin:
"AMSAT will demonstrate packet radio at the meeting to show the basic technique
and typical equipment. The hardware demonstration is being supported by three
companies. Radio Shack is supplying the computers, Yaesu is providing the HTs
and TASCO2 of Japan is supplying their ultra-miniature TNCs which are the size
of a pack of cigarettes. JAMSAT officials were especially helpful in
obtaining the TASCO TNCs and expediting them to the U.S. Ralph Wallio, W0RPK,
AMSAT's VP of Operations, is integrating the demo equipment."
OK, where do I get one of these Tasco TNC's? Does anyone know anything
about them?

Subject: Monitor fighter pilot training on shortwave
x
Over a year ago, we reported apparent USN missile test
firings in the Gulf of Mexico monitored on 3.109 MHz USB.
Back then, tactical identifiers like Antietam Test and
Seabreeze were used.
Over a year later, 3.109 MHz is still alive with
activity. Seabreeze, purportedly the Navy facility in
Pensacola, Florida, is still heard weeknights. Other
stations like Spartan (the USS Lexington?) and Lake Cham-
plain Test, have been active, apparently in missions to
train fighter pilots.
Here is just a small sample of military aero stations
logged in the past few years:

Subject: Standing up to UPS
Well, here are my reply comments to the UPS late filing. If you haven't
written yours yet, WHY NOT?? At the very least, grab a piece of paper,
write your name, call and "Docket 87-14" on it, and say
"I strongly urge the Commission to reject the request by UPS to
reallocate 220-222 MHz from the Amateur Service to the Land Mobile
Service. I fully support the comments of the ARRL and [insert any other
names here :-)] in this matter."
DO IT BEFORE MARCH 31ST!! BETTER YET, DO IT NOW!!

FEDERAL COMMUNICATIONS COMMISSION
Washington, DC
In the Matter of )
Amendment of Part 2 ) General Docket #87-14
of the Commission's Rules ) RM-4829
Regarding the Allocation ) RM-4831
of the 216-225 MHz Band ) RM-4983
To: The Commission
REPLY COMMENTS OF PHILIP R. KARN, JR., KA9Q, TO LATE-FILED
COMMENTS OF UNITED PARCEL SERVICE OF AMERICA, INC.
I wish to oppose, in the strongest possible manner, the
comments of the United Parcel Service (UPS) regarding the
reallocation of 220-222 MHz from the Amateur Service. UPS
blithely asserts that "the functions that Amateurs perform
at 220-222 MHz can be conducted elsewhere without signifi-
cant inconvenience". Apparently UPS has not read very many
(if any) of the comments filed by thousands of radio ama-
teurs, including myself, or it would not have made such an
incredible statement.
ERRORS OF FACT IN THE UPS PROPOSAL
To begin with, the UPS comments are littered with fac-
tual errors, omissions and distortions. (One wonders how
much actual research they did in the extra six months after
the original comment deadline they took to prepare their
comments). For example, they casually omit mentioning that
420-430 MHz is unavailable to American amateurs operating
near the Canadian border. Or that in many areas large parts
of the 420-450 MHz band are rendered virtually unusable for
long periods of time by military radars, to which amateur
operation is secondary. Or that the bottom 25 MHz of the
former 1215-1300 MHz band was taken away from the amateurs
several years ago to make way for the Global Positioning
Satellite system. Or that amateur operation on the 902-928
MHz band is on a secondary basis, with the band being com-
pletely unavailable to amateurs in parts of Colorado and
Wyoming. Or that high speed packet radio is confined by FCC
rule to frequencies above 220 MHz (not 50 MHz as implied by
UPS).
THE AMATEUR PACKET RADIO NEED FOR 220-222 MHZ IS STRONGER THAN EVER
March 18, 1988
- 2 -
Military radar on the 420-450 MHz band has recently
emerged as an especially serious problem with the new, high
speed packet modems that are an important part of amateur
packet radio's future. Bandwidth requirements dictate that
such modems operate above 220 MHz; however, contrary to the
assertion made by UPS, there is NO "abundance of spectrum"
between 222 and 225 MHz in the New York/New Jersey metropol-
itan area, where I live, and in many other metropolitan
areas. As a result, the 220-222 MHz segment has emerged as a
key factor in the development of amateur packet radio. Mon-
itoring the 220-225 MHz band in my area with a spectrum
analyzer revealed that the existing low-speed packet chan-
nels in the 220-222 MHz range have utilizations consistently
higher than those of the voice repeaters in the 222-225 MHz
range, rivaling even those of the most popular 144-148 MHz
band repeaters. It is not unusual for the channels to
remain busy all night forwarding messages, and this is under
routine (not emergency) conditions.
Even in situations where the higher frequency bands are
also usable for packet radio (i.e., where inferior propaga-
tion and military use permits) recent research and experi-
mental results by myself and others since the original com-
ment period expired have shown that "cross-banding" is an
extremely effective technique for improving the efficiency
and performance of a packet radio switch. In cross-banding,
each switch node transmits on one frequency band while
simultaneously receiving on several frequencies on other
amateur bands. Other nodes operate similarly, with each
listening to the transmit frequencies of its neighbors.
Frequencies are "reused" (assigned to more than one
transmitting station) in a controlled manner to avoid
interference, much like cellular radio.
The advantages of this approach are many, as collisions
(interference caused by simultaneous transmissions on the
same frequency) are avoided. This results in increased capa-
city and enormously improved network stability under heavy
load, such as that to be expected during the communications
emergencies for which amateur radio exists to serve the pub-
lic interest. The full-duplex (simultaneous transmission
and reception) mode of operation is absolutely fundamental
to this concept. However, _f_u_l_l-_d_u_p_l_e_x

We believe that high speed packet radio allocations on
at least three separate amateur bands, including 220 MHz,
will be necessary to make this scheme work. But if amateurs
lose the 220-222 MHz segment there is simply _n_o room for
such an allocation in the remaining 222-225 MHz portion.
This will severely cripple the development of this highly
promising technique and hinder the ability of amateur radio

to fulfill another reason it exists: to advance the state of
the art in radio communications technology.
OTHER SOLUTIONS EXIST TO UPS'S STATED NEED FOR MOBILE COMMUNICATIONS
One wonders why UPS is suddenly so interested in the
two-way voice business. As a radio amateur and computer
user I have used UPS's excellent services many times, and it
seems that they have little to gain from two-way voice radio
communications. One would presume that UPS might benefit
from record (as opposed to voice) communications when
dispatching pickups and deliveries. One-way data transmis-
sion using printers attached to FM broadcast subcarrier or
conventional paging receivers would be far more efficient
for this purpose, especially since the truck drivers seem to
be out of their trucks (and away from any radio equipment)
much of the time. If truly necessary, voice communications
could be provided by portable cellular telephones at a much
lower overall cost than a dedicated UPS system.
THE COMMISSION SHOULD DENY THE UPS REQUEST
The filings to date in this matter have repeatedly and
overwhelmingly documented the strong need of the Amateur
Service for the 220-222 MHz band. Because the (late) filing
of the United Parcel Service has not contributed any new
ideas or additional information that would lend weight to
the Commission's ill-considered proposal, I strongly urge
the Commission to reject it in its entirety. Furthermore,
the Commission should resolve Docket 87-14 in favor of the
Amateur Service as soon as possible. Development of amateur
packet radio networks have taken and will continue to take
considerable sums of money, and the reluctance to invest
further in 220 MHz gear that may become useless has severely
dampened packet radio development. Any additional Commis-
sion delay in reaffirming the Amateur Service's need for use
of 220-222 MHz translates directly into a delay in fulfil-
ling the fundamental Basis and Purpose of the Amateur Radio
Service.
Sincerely,
Philip R. Karn, Jr.

Subject: WRSU Radio Reunion Weekend
WRSU, the student operated radio station of Rutgers, The State University
of New Jersey, is celebrating our 40th year of broadcasting.
As part of the celebration commemorating the first broadcast of WRSU,
which took place on April 26, 1948, we are planning an Alumni On the Air Day on
Saturday, May 21, 1988. This is the same weekend as the annual Rutgers Alumni
Weekend. We would like to have the alumni of WRSU come back and play records,
do news/sportscasts, play old tapes, and tell stories of WRSU history. With
other WRSU contemporaries, an alumni staff will do a radio show as in the "good
old days". The amount of total air time given to the First Annual Alumni On The
Air Day will depend on the response we get, so we need to hear from you!! The
deadline for the alumni air staff is April 30,1988.
For those of you who do not wish to be on the air again, but are
interested in how WRSU has been doing since you left, we will have an OPEN
HOUSE in our studios in the Rutgers Student Center, fourth floor, from 10 am to
6 pm on May 21, 1988. Refreshments will be served.
If you are interested in being ON THE AIR again, or just want to know more
about WRSU-FM, Rutgers Student Radio, please contact us:
Jerry Donnelly '78, Broadcast Administrator
at 201-932-3710 or 7800
or send attached form to:

Ham Radio Phone BBS List 3/88
The following is a list of some telephone BBS's that support Amateur Radio.
Some of these are strictly for hams, while others support "SIG's" (special
interest groups) for hams or have radio-related files or message sections.
If you call one of these BBS's and find nothing to indicate it's relationship
to Ham Radio or find that it has been disconnected, let me know so I can
archive it and clean up the list. I can't gaurantee the accuracy of this list,
but I do strive to keep it as up-to-date as possible. Please send any updates,
changes, or comments to me. 73, Tom Brown KA2UGQ.

1. Brazil AMSAT To Build Educational Satellite With AMSAT NA
Brazil AMSAT (BRAMSAT) and AMSAT North America (AMSAT NA) have agreed in
principle to collaborate on a joint educational satellite project. The
satellite will carry an advanced voice synthesizer and be designed for easy
reception by Amateurs with minimal equipment. Called "Brazil Peacetalker",
the satellite will transmit voice telemetry of spacecraft operating conditions
as well as a voice greeting to other space faring nations to work towards the
peaceful use of space. This theme may lead into the International Space Year
now planned for 1992.
Brazil Peacetalker will be designed to be received by schools using minimal
equipment and for Amateurs who wish to explore space sciences by logging and
studying the telemetry. Preliminary plans have the telemetry read in English
while the greeting messages would be articulated in Portuguese, English and
Russian. Other languages could be added. The specific messages will be
programmable by a ground command station which shall be under the control of
international authorities.
The preliminary agreement was reached in Boulder Colorado March 6 when BRAMSAT
President Dr. Junior De Castro, PY2BJO, met with AMSAT NA officials. A
definitive agreement is imminent these officials stated. The AMSAT Board of
Directors which met March 12 and 13 has reviewed the project and finds it in
AMSAT NA's interest to consummate a final accord with BRAMSAT. If plans go
forward as expected, the Brazil Peacetalker will be launched in early 1989
into an approximately 800 km high orbit. Plans call for Brazil Peacetalker to
be launched with AMSAT NA's packet radio satellite and perhaps a third
satellite of the same class. These satellites will be small but highly
capable. An important design criterion is that they be easily heard on the
ground with omni-directional antennas.
The satellite will be funded by BRAMSAT and the tasks partitioned between
organizations based on a to-be-negotiated Statement of Work. A preliminary
design has been completed and construction will begin upon signing of the
definitive agreement.

3. Board Meeting Highlights
The AMSAT Board of Directors met at AMSAT Headquarters in Silver Spring,
Maryland March 12 and 13. Here are the highlights of the two day meeting.
Jan King, W3GEY, currently Vice President of Engineering, was elected Chairman
of the Board of Directors. Jan co-founded AMSAT in 1969 and has been a Board
member since then. He is the only original member of the Board still active.
He replaces John Browning, W6SP, who resigned from the Board last month. John
Henry, VE2VQ, formerly First Alternate Director, was seated upon W6SP's
resignation and participated in the Board meeting as a full voting member.
Andy, MacAllister, WA5ZIB, elevated to First Alternate Director, did not
attend.
Administrative Director Martha Saragovitz was recognized and applauded on
having completed 10 years as an AMSAT employee. She will receive a plaque to
display on the office wall together with her other meritorious service awards.
Deliberations of the Board covered matters such as liability insurance and
hazard insurance, accounting for volunteer labor expenditure, ASR costs and
the 1988 budget. Income has sagged probably due to AO-10's demise. As a
result, unless renewals turn around, the budget will have to be trimmed
sharply. The influx of new members and renewals associated with the Phase 3C
launch should revive a healthy financial picture, however, all agreed.
Field Operations progress was reported by VP of Field Ops, Doug Loughmiller,
KO5I. A strengthened Field organization is at hand Doug said. The AMSAT News
Service bulletins will be partitioned into smaller blocks to facilitate
transmission through the packet radio network and on to packet BBS. The
changes will go into effect in late March.
AMSAT will play a key role in the International Space Year (ISY), if plans
continue on course. AMSAT is forced to defend its copyright on its corporate
name several times per year at least at a cost of several thousands of dollars
in legal fees. New accounting software is being installed at Headquarters to
make the bookkeeping easier and more auditable. Telecommunications costs are
running at about 10% of the annual budget or about $20,000. Electronic mail
comprises more than half of that amount but the expense was recognized as
reasonable and the cost of doing business in a dispersed office environment;
with volunteers spread all over the world.
Recognition of launch insurance donations will be made in ASR at the earliest
opportunity. A very important joint AMSAT-TAPR Digital Signaling Processing
project was given the go-ahead. The object will be to manufacture for sale
special DSP boxes later this spring. The hardware sales will generate a
revenue stream to help pay for the PACSAT satellite now being developed and
will complement an on-going software sales effort.
A joint Brazil AMSAT and AMSAT NA project for an educational satellite was
approved subject to final contract definitization. This satellite will
tentatively be launched in 1989 with AMSAT NA's PACSAT.
A collaborative effort with Weber State University in Ogden, Utah is highly
desirable and likely the Board was told. Discussions on this subject will
continue apace. Weber State built the NUSAT-1 satellite and operated as well.
Fund raising program initiatives were very much on the Board's mind with
PACSAT coming up after Phase 3C and Phase 4 looming large on the horizon.
The minutes of the meeting will be available as soon as the Secretary to the
Board finalizes them.

4. Motorola Donates Complex DSP Package
Steve Sagerian, KA0YRE of Motorola (at least partially responsible for the
68000 board network controller that CAPRA has done) has really come through
for the joint AMSAT-TAPR Digital Signal Processing (DSP) project. He arranged
for the DSP operations branch of Motorola to come up with two 56001 EXP kits.
This kit comes with bare boards, boot ROMs (a debugger, monitor), PAL's, and
several manuals. Just to get things rolling in a hurry Motorola decided to be
very generous and throw in two DSP56001 chips. This board has a 20.48 MHz
clock and processes 10.25 million instruction per second. Using the
architecture to its fullest one could do a 1024 point Fast Fourier Transform
(FFT) in 3.48 ms.
Steve and Bob McGwier, N4HY, will be building these two units up. They expect
further support from Motorola as they get applications back from AMSAT/TAPR.
AMSAT expresses it thanks Motorola, Inc. for its generous support in the form
of several thousand dollars worth of hardware and software!

5. Board Reviews Dues Structure; New Rates Reflect Postal Increase
AMSAT Headquarters announces that a member dues increase will go into effect
May 4. Effective May 4th, the new rates are:
U.S. Domestic members: $30
Canada and Mexico: $36
Other foreign: $45
In accord with the Bylaws, a member dues change comprises a Bylaws change.
Consequently, the dues change shall be effective thirty days after publication
unless 10 % of the voting members object in writing. If so, then a general
membership vote will be held by mail.
The dues increase was made necessary by increased production and especially
postal costs. The Board has directed a 25% reduction in the cost of ASR and
has asked the president to provide members a view as to how dues are spent.
(Currently ASR consumes more than 25% of the AMSAT annual budget, i.e., costs
more than $50,000 per year.) The Board meeting held March 12 and 13 approved
the dues changes. The last due increase was in April 1983.
Beginning May 1, all overseas annual members will receive ASR directly from
AMSAT via Air Mail. Previously, re-mailers had helped in distribution by
re-mailing from their locale. However, the additional delays incurred and
complaints from members concerning the re-mailing process has resulted in the
change in overseas mailing method and rates. Overseas Life Members may opt to
have their ASR sent by Air Mail by remitting the additional postage costs.
Otherwise ASR will be mailed sea mail to overseas Life Members.
Annual members should renew early to beat the dues increase. You may renew
for several years in advance.

6. Short Bursts
Dave Medley, KI6QE will be handling the AMSAT 75 Pacific Coast net according
to Regional Coordinator Ross Forbes, WB6GFJ.
***
Rumors suggest the launch of the Russian space shuttle is imminent.
***
The USSR has launched and Indian Remote Sensing satellite according to Max
White at the Royal Greenwich observatory. The IRS payload was launched March
17 at 0600 southbound from Tyuratam in the USSR. It will be handed over by the
Russians for use at the end of the month. The launcher was the SL3 Vostok.
Imagery is on S and X band, but RGO believes that a beacon may exist on known
Indian frequencies in the 137 MHz band and a search of this region may prove
fruitful. The weight of the payload is 950 kg

The first air drop of supplies to the 13 man Transpolar Skitrek Expedition
took place on March 14th. Eleven drops were made in two passes over the
skiers. All supplies arrived safely on the ground including fresh fruits and
vegetables. The skiers constructed a large igloo to serve, along with the

igloo for drying damp clothing, a problem they could not solve earlier. The
numbness in their limbs which the skiers complained of several weeks ago is
now gone. All skiers are in good health. The group conducted scientific
research during their stay including medical exams and stress tests. On
Wednesday, March 16th, the 13 trekkers packed up and continued on their
journey.
Rick Burke, VO1SA Portable UA0, at Sredniy Island, CI8C at Resolute and North
Pole 28 Ice Island Station 4K0D are all on RS-10/11. Listen for them on the
northern portion of passes in the 29.417 - 29.420 MHz range of the 10 meter
downlink. Rick's daily routine includes a 1 km walk from his quarters to the
shack during which he has an armed escort in case of polar bears (he hasn't
reported seeing one yet). The weather has been severe at both Resolute
and Sredniy with strong winds and snow.
Winds the skiers have encountered lately have been about 15 km/hr with
temperatures around -35C. As of Thursday, March 17th, the skiers had made
excellent progress since continuing their journey. Their l
ocation was
83d 11.7'N, 97d 26.6'E as they completed Thursday's trek. This brings them
to a total trek distance to date of 225 km. Since the digitalker and
2 meter beacon onboard UO-11 have not been functioning continuously due to
programming problems, schools and others following the trek may access any
position information they have missed on the W0RPK AMSAT Bulletin Board
(1-515-961-3325) or in ASR.
Many of the elementary schools following the trek will be contacting each
other and comparing trek watching activities. These include schools in the
U.S., Canada, New Zealand and South Africa. This sharing is being coordinated
by AMSAT's Science Education Advisor Rich Ensign. If you want an elementary

I was wondering why outfits like Amateur Electronic Supply don't do
something like this. Can't they use the Postal Service, or Purolator,
or something? They are *big* UPS customers. Also, companies like Icom
won't make any money out of this, since UPS will be building their own
equipment.
At the very least, anyone ordering ham gear should insist that it
not be shipped by UPS, with an explanation why.
Has anyone considered buying a few shares of UPS stock, then calling
the company's stockholder relations department and asking why UPS is
trying to sabotage his or her hobby?

UPS is one of the biggest, if not *THE* biggest privately held corporations
in existence. Other than the 220 MHz-late-comments-trick, they are quite
an impressive operation. Unfortunately, I doubt that losing the truckload-
a-day of ham gear that they move would ever be noticed.

Subject: Grove's new 1988 "Shortwave Directory" looks good

Bob Grove's new 1988 Shortwave Directory is now availa-
ble, and it's a masterpiece. Coverage concentrates on
shortwave utility (non-broadcast) stations in the 1.8 -
30 MHz range, although listings of VLF stations are
included.
The 1988 directory is big - about double the size of its
predecessor. I will use and enjoy this directory as much
as I have the previous 2 editions.
The frequency listings from Grove's older books have been
updated. New coverage is given to topics like identifi-
cation of shortwave jammers [courtesy of yours truly] and
facsimile. Grove collaborated with other well respected
radio monitorists, who contributed detailed chapters
covering specialized topics. The new, very thorough RTTY
section will be welcomed by many.
The upgraded, very readable type face and interesting
photographs are appreciated. With other directories sel-
ling for upwards of $30, this book is a square deal at
$17.95.
Copies of the Shortwave Directory are available from:

Subject: Software for portable packet/rtty
My package runs just fine on PC-compatible laptops. All you need to get
on packet with it is a "KISS" mode TNC and radio. Many manufacturers are
now including KISS compatibity in their firmware (Kantronics advertises
theirs as "TCP/IP compatible"). Not only do you get the ability to run
the very same true high level networking protocols used on the ARPA
Internet, but you can also speak "plain" AX.25 and handle multiple
concurrent sessions of various types.
And the best part is that it's all free for noncommercial use --
including complete C source code. You can get the software and
documentation from a variety of sources. If you're on the Internet, get
it by anonymous ftp from louie.udel.edu under /pub/ka9q; if not, you can
get it on 5.25" floppies from TAPR, PO Box 22888, Tucson AZ 85734. You
can either provide your own disks (include 3 blank disks, return postage
and $2 for copying costs) or you can have TAPR provide the disks for $1
+ $.75/disk = $3.25.

Subject: TNC RFI Problems
In early TNC-2s there was a variable capacitor across the clock crystal
which allows you to "pull" the frequency one way or the other a small
ammount. The solution is not good, since it still allows RFI, but
you can choose where in the spectrum it lives, and can pull it off
onto unused frequencies (145.03?) at your QTH.
Don't go too far pulling the freq, or you may find bit timing changing
and thus changing your "baud" rates.
Other possible solutions:
a) cut the offending pc trace and put a 100-150
ohm resistor in series to slow down the edges on that waveform.
b) Put ferrites on every line (power, radio, RS-232) coming out of the TNC.
c) put bypass caps on every line coming out of the TNC (small values).
