AO40 Transmit troubles
Thanks to all who replied on "finding myself". I finally have made
it "to" and "back" from AO40 (at least on cw so far). Combination
of transmit polarity (I SWEAR I had the switch in RHCP the first time,
there is NO WAY i could have overlooked that....... 8-) )
and possibly being outside of the transponder passband (due to doppler).
I tried the "find the beacon" and move xmit and receive equal but opposite
amounts and found my signal within seconds! (Got spoiled using the
736 with auto tracking, now using 2 radios and have to tune them
separate!!) Very surprised that 10 watts on 435mhz returned WAY too
loud of a signal even with the bird at 57,0000+km!!! About 2 watts
did wonderful for CW (I have pretty high gain beams on 435 and a very
low loss figure). Thanks again!!
