 Just a quick note here about the ACC-L mailing list...

  It is hosted on gitvm1.gatech.edu (gitvm1.bitnet for those in both worlds).
If you have trouble getting to Mike's mirror on slic.cts.com then you can
send mail to [e-mail]. In the body of your mail message,
put "subscribe acc-l your-name". Replace "your-name" with the name you wish
to have appear on outbound messages from you. Please don't use psuedo names or
"handles" on the list.

  As always, problems or questions can be sent to me (I am the list owner and
am responsible for it if it breaks (: ) at the address(es) in my .sig.

  The folks at ACC are subscribed to the list via their Compu$erve account, but
I have no idea how often they check for mail.

  Enjoy,

This is the first time I'll be attending the HamVention

can give me a leg up on do's and don'ts to make the most
of the trip.  I'll be attending Thur - Sun.  I'd really
appreciate any suggestions!  I'm looking into satellite

I doubt if those who do the FCC license paper work (all two of them :-)
also maintain the computer systems.  Anyway, all government computer and

Can anyone help me?  I passed my test to become a no-code tech six months
ago, and I haven't received my license yet.  A couple month ago, I found
out that the FCC lost all my paper work, so I had to send my paperwork in
again.  They said that they were going to put a rush on it and that it
would only take four weeks.

I would greatly appreciate it if anyone could tell me why it takes so
long to get a license.  Also, if anyone could speed my license along
would also be appreciated.

My name is Rich Crossler and I live in Moscow, Idaho.  My friend who gave
me the test was KA1POR.  He has been trying to contact the ARRL to see if
they can shed some light on the difficulties.

Thank you for your time.

  Sorry, Karl, I disagree.  The orbital data has been posted here
for some time, and is useful to us.

  I just wanted to make it clear that not all of the readers of this

Hmmm, seems to me that P43WLP would be from Aruba.  And that's a pretty
long callsign for a station from Aruba.  The prefix for Paraguay is "ZP."

Unfortunately, I know of no DX callsign server around.  Maybe someone
else will.  Just figured I'd bring the callsign discrepancy to your
attention.

Sorry for the error in my posting of two callsigns I am trying to find routes
for.   The callsign given to me as P43WLP was INDEED from Aruba, and not from
Paraguay.  I read the wrong line while I was typing.

Yes that should be a Aruba callsign. Since his first name is William he
likely requested his initials. Its easy to get the call of you choice in
many countries.

But to answer the original question if you plan to work and 'QSL'
lots of DX stations a DX Callbook is a good investment.      ^^^

Yup. Aruba. The call is valid, too:

Yes, in fact I know of at least one 202 that's taken a bit of a beating over
its life, with zero problems. Nice little radio, with all of the bells and
whistles, at a good price. You don't get wide-band receive. This is bad if you
want it, but it's good if you want an interference-free radio.

I think this explanation is kind of mixed up, or too simple, or something.
What about the current minimums, isn't the I2R loss there less than the matched
case? This "reflected power is converted to heat in the amplifier" thing bothers
me too. If I were an amplifier and the load didn't want all the power, I just
wouldn't generate as much power.

I thought it was dielectric losses at the voltage maximums, which
is why untuned dipoles matched with tuners work best with air spaced
ladder lines. You can run a high swr between the tuner and dipole
without the high losses coax would have in such a mismatched situation.

Hi Ed, I loved Gary's "spitting into a firehose" analogy and the 100%
theoretical reflection of reflected power is correct due to the
conjugate match at the antenna tuner.  I measure 100w out of my
transmitter into my antenna tuner.  I measure 150w forward power out
of my antenna tuner.  Neglecting losses, that means that 50w is being
reflected and re-reflected so I am actually radiating 100w.  The two
things that cause SWR not to matter is the near-100% re-reflection of
reflected power at the antenna tuner and near-lossless transmission
line.  It leaves reflected power with but one choice...  RADIATE!

Well Gil, I agree that this story has the potential to become an urban
legend, which is why I posted the synopses of the press coverage from last
year: to correct the errors from the original post. The fact is, it
happened. Yes, it would appear that the San Diego Sheriff had no legal
authority to confiscate the HT, but the department, with the aid of the
local FCC Field Engineer, did succeed in coercing Chris to "voluntarily"
donate his HT to the SD RACES rather than face prosecution. The last I
heard, the San Diego County Supervisors voted to decline the "gift",
although that part I have not been able to confirm. One thing that came out
last year when this story was fresh that I did not note in my earlier post
is that at about the same time as Chris used his HT on the Sheriff's
frequency to summon aid, another person was causing malicious interference
on Sheriff's frequencies. The word is that the two together greatly
irritated the Sheriff and drove the coercive activity that relieved Chris
of his HT.

Since I'm a little too far North to follow the San Diego papers, does
anyone from SD have the actual current status of this story?

To: [e-mail]

I just built a copper j-pole out of 1/2" copper tubing. It works
great (even if I say sio myself) :-)

Here are the diminsions I used, swr is well below 1.3 all across
the band:

Reflector - 57.375"
Stub      - 19.125"
Gap       -  1.250"
Feedpoint - ~2.500"

The antenna was designed for 146.00MHz.

Good luck !
