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.
