Re: AO-51 PBBS OPEN !



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
