First Pass on the Transponder

AOS = 0710 utc 7/21/2001:

Well, I was still up on the roof re-installing the preamp in a wx-proof box
as a light mist dropped ;-)  I had decided to get the system back on-line.

Finally turned on everything at 0730 utc.  Found the beacon at 123.295.5 =>
2401.299 MHz; pretty strong so I copied a few blocks of telemetry.  Then I
went tuning for my uplink.

Called CQ at 0744:  435.628.2 Tx => 123.336.8 Rx => 2401.342 with about -29
Hz doppler.
First QSO was with JA0TOG at 0800.
Tuning I found my neighbor Mike,WL7BQM-mode LS, in contact with KO6RS,
Dave.  Then joined by WB6LLO.
Had a nice contact with them for an hour when JF1SAG, JH1NPQ, and later
Went QRT at 0945 utc then collected some telemetry for awhile.

Good strong signals with the low squint.  I did find that signal was
slightly distorted when using my internal preamp turned-on in the FT-847.
Voice much clearer with it turned off, though the s-meter dropped from s-7
to s-3 on most stations {noise floor went from s-3 to s-1/2 {receiver also
quieter between words}.  I ran about 9w into the M2-436CP42 {16.5 dBic} for
an ERP of ~400w.  Heard myself with an S-2 signal.

This was my first operation on AO-40 from home {operated from WL7BQM one
night during the first xponder test}.
Tomorrow I will get the 1269/145 Tx-conv. set up {AOS = 0209 utc}.
