Hi Jeff,
The 435.150 transmitter signal is indeed LHCP, and the .300 is RHCP. We are running slightly less power on the .150 downlink, currently about 400 milliwatts on .150, and 500 milliwatts on .300. The L band digital uplink is certainly a challenge, but it allows us to open the BBS up without incurring some interference problems we have had when using the V band BBS uplink via the SQRX receiver. I run a similar system on L, 10 watts through 50 feet of LMR-400UF to a 24 element looper, with the added problem of long needle pines HIHI. I could really use some time on the chainsaw, and an L-band amplifier or more antenna.
73, Drew KO4MA

AO-51 PBBS was on last evening; however, seemed to be hard to work. On a 45 degree pass I was receiving about half of the signal level that I normally receive from AO-51 and I was unable to connect using L band and 10 watts (22 element M2 yagi). Normally AO-51 is full scale on S-Meter when above 20-30 degrees. I have polarity switching capability and seemed to be LHCP instead of the normal RHCP. Maybe one of my feedline cables got caught on something and my yagis are pointing in the wrong direction. This has happenned to me before :-)

I confirmed that AO-51 PBBS ON now.
