Before you put yourself through the agony of the damned, check out the
switching power supply. I bought a P-75 about a year ago and almost
the first time I turned it on it was so noisy. I finally traced it to an
inadequate line filter on the switching power supply. A commercial grade
filter was added in series with the existing but ineffective filter in
supply and presto all my computer birdies went away ~8^).

Well let me say this, you don't have to worry because you already have a
nice callsign (a 1X2). Please let's not end the vanity callsign system, I
think it's the savior to our hobby. I don't care whose application gets
processed first (even if I'm the last) I just want a 1X2 or 2X1 callsign
since I wasn't even alive when they were issuing those callsigns. Suing
is not the answer to you're problems. A callsign is a callsign. It's just

Does anybody have any experience with the new Astron switching power
I'm heading to N4ZC's at the end of the month for CQWW SSB and am
taking my TS-850 and RS-20A. The 20A weighs 18 lbs. The new 25 amp
switching supply weighs 4.2lbs. Sure would cut down on the weight.
I called AES and they don't stock them.
So the questions is any wisdom on the switching supply and does any
one know who is stocking them??

Just for kicks, I turned Altavista loose to see if the Alpha/Power Web page
was up yet.
SHort answer: No.
Long answer: Altavista turned up about 30 hits. Many relating to the DEC
"Alpha" processor chip. Some relating to psychology and pseudo-psych stuff
about cannabis use and Alpha brain waves or some such. One pointed to a
group named Alpha, dedicated to the supremacy of the Aryan race.
Make sure you go for the one you really want when their Web site is up!

An all YL team operating from the QTH of WA6YOO and using the call sign ALL
CALIFORNIA SIX FOXY LADIES (AC6FL) acchieved the following results, using
low power. Operation was SSB on 15, 20, 40, and 75.
QSOs: 909 x 2 points x 57 multiplier (no NWT) = 103,626 points.
Location: San Diego County
This was a first time effort for the team and only a couple of them had
participated in contest or Field Day before. The participants were:
N6UWW - ELLEN Team Leader and Head Cheer Leader
KB6NMK - JO
KM6WF - GAYLE
KE6BUE - BECKY
KD6BTY - CINDY
KF6FYJ - MEGAN
KF6EFN - CAROL
KM6WG - JENNIFER
The ladies took turns operating and computer logging and report they'll be
back again next year to try to improve their score. My wife Jerry played
"house mother" and kept the coffee pot full. Me? I watched TV, read the
newspapers, and napped. The last thing the ladies wanted was me messing up
their concentration. You'll see me in SS.
