* ITAMSAT PROBLEM *
===================
Earlier this month, the PSK modulation on the primary ITAMSAT transmitter
became more and more difficult to decode.  A residual carrier and lower
output power seem to indicate a failure in the PSK balanced modulator,
being worse at the current low power setting.  Increasing the power level
makes the demodulation better but is not acceptable due to power budget
constraints.  Ground controllers decided to switch to the secondary PSK
trasmitter on 435.822 MHz.  The first two passes over Italy confirmed the
correct operation of the spacecraft and WOD are being taken to analyze the
performance of the satellite in this new configuration.  The BBS is working
as usual and status bulletins are uploaded to the satellite.

* CLEMENTINE IMAGES AVAILABLE *
===============================
Recent images of the Moon that were downlinked by the Clementine spacecraft
are available by ftp or email across the Internet.  For those with ftp
access, simply ftp to clementine.s1.gov [128.15.32.9] and look in the
directories under pub/clementine/images.  For those with email only, send
a message to [e-mail] with a blank subject line and text
of "help" only.  The email server can provide directory listings and
uuencoded binary files such as GIF images.

* OSCAR-13 MODE-S EXTRA BEACON *
================================
In response to requests, the Mode-S session now includes 2 MAs beacon at
the start.  Mode-B is unaffected.  The revised schedule is:

M QST *** AO-13 TRANSPONDER SCHEDULE ***  1994 Mar 19-Apr 04
Mode-B  : MA   0 to MA  90 |
Mode-BS : MA  90 to MA 120 |
Mode-S  : MA 120 to MA 122 |<- S beacon only
Mode-S  : MA 122 to MA 145 |<- S transponder; B trsp. is OFF
Mode-S  : MA 145 to MA 150 |<- S beacon only
Mode-BS : MA 150 to MA 180 |        Alon/Alat 180/0
Mode-B  : MA 180 to MA 256 |

* FO-20 SCHEDULE *
==================
The FO-20 command station announced that FO-20 will be placed in Mode JA
(Analog transponder mode) during Field Day 1994 (25-Jun-94 18:00 UTC through
26-Jun-94 18:00 UTC).

The current operating schedule is as follows:

Analog mode:
                23-Mar-94 07:52 -to- 30-Mar-94 08:15 UTC

Digital mode: Unless otherwise noted above.

I say: I suppose it depends on which legend re: the origin of the term
"ham" as it applies to amateur radio comes from. Several of the legends
indicate the term is from either initials or an acronym, and both would be
properly capitalized.

          Here's more to worry about: why capitalize

          MF, HF, VHF, UHF, CW, AM, FM, SSB, D-layer, E-layer, F1-layer,
          F2-layer (and why no A- B- or C-layers?), .....

I say: In the above examples, the capitalized letters are initials

          Any difference in specs between a 2N2222 and a 2N2222A xsistor?
          (And why did I capitalize the N and A?) An xmtr I'm building
          calls for 2N2222A's but all I have are dozens of 2N2222's (from
          dumpster diving behind the Engineering Department's building -
          amazing what they throw out).

          I imagine the `A' version is the new and improved model.

I say (now on the real subject): The "A" devices have a different gain
characteristic, (hFE @ 10v 10ma 50-325 for the 2222, 75-325 for the "A"),
higher minimum breakdown voltages, lower VCE sat voltage. In most cases, it
won't matter which you use. The chips are the same and the manufacturer
screens for part type selection. Since the 2N2222 minimums are lower than
those for the 2N2222A, A 2N2222A can always sub for a 2N2222, a 2N2222 may
not always work for a 2N2222A. Both devices were registered at the same
time, so it is not a matter of "new and improved". Check a Motorola small
signal spec book or MIL-S-19500/255 if you really need to know the finer
points.

ARRL (should be capitalized here :-) has an AUTOMATED ELECTRONIC MAIL
SERVER from which you can request info on hamfests (or HAMfests) as
well as many other topics.

For the hamfest info specifically, do the following:

mail [e-mail]
...in the body of the letter type:
send HAMFESTS-USA
quit

...and just cntl-D out and you will receive the info in short order.

Phfffft! The phase flatness through the audio phase shift networks
used in amateur phasing SSB rigs was much worse than any phase
distortion in a filter rig. The audio phasing network had to cover
octaves while the crystal filter only has to work over a tiny fraction
of an octave.

Amplitude flatness, low frequency response, and total bandwidth were
often greater with phasing generators. That gave a more AM-like sound
to phasing generated SSB.

We solved that problem years ago without need of DSP. We just
put a delay line in the main channel so the AGC has time to react
before the audio gets out of the box. It used to be a mercury
column, but today it's often a bucket brigade shift register.

Not true.  A phasing-type SSB generator specifically depends on a
90 degree phase difference between the two channels.  If the phase
flatness were bad, you would get terrible unwanted sideband supression.

Same thing with amplitude flatness.  The phase shift network's two
channels must be matched to within a fraction of a dB to get good sideband
suppression.

A typical SSB crystal filter has a couple dB peak-to-peak ripple across
the passband with similar ripples in the group delay.  It is easy to
do much better than that with a phasing-type exciter.

: novelties now, but they are more xepnsive to built than RF processors.
: Why AF clippers are worse than RF (IF) clippers?  Consider a 500Hz
: tone test.  With AF processor you will get extra 1000,1500,2000,2500
: Hz tones.  With RF (SSB and DSB) processor 500Hz will be the only
: output. Please note that some older rigs have "implicit" RF
: processors. For instance, SWAN 500 has 7360, a beam deflection tube,
: as a DSB modulator. By clipping peaks, it acts with the following XTAL
: filter as a DSP processor.
:
If you clip an ideal DSB waveform (1 kHz modulation), aren't there
two tones spaced 1 kHz apart that could generate IMD products at
1.5 kHz and 1.5 kHz (receiver output)?  What if you had a significant
amount of carrier leakthrough that was cleaned up by the crystal
filter?  Couldn't this give you extra tones at 1, 1.5, 2, and 2.5
kHz (at the receiver)?

Subject : Re: Voice mail on a repeater?

Are there any repeaters left in this country that just repeat, including
no musical tones or beeps when you drop your carrier? I miss the old
days when all one heard was a nice solid kurchunk of the repeater
receiver's squelch tail quickly followed by a second squelch tail from
my receiver (the repeater carrier would drop off after 1-2 seconds).
This seemed to be the way most of the public safety repeaters were
also set up (particulary the California Division of Forestry
repeaters back when I was a fireman in the early 70s).

Gary: I'll be disappointed if your repeater beeps.

I'm not sure if the hamfest list is as complete as it could be, but it's
pretty good. Have fun!

Any guesses as to the propagation mode of my 21 MHz contact
nearly 11 years ago

June 26, 1983  3 watts SSB (my end) with W4VNU at 1051Z
(12:51 PM Hawaii standard time)  Almost 7 AM in South
Florida.  Antenna was a simple wire antenna a few hundred
yards from the beach.

My guess is multiple hop E skip.  We are
