Bob,

Just saw the message about L band being activated and checked it out on the morning western pass. Signals were much stronger on 435.300 than they were on 435.150 and I do have polarity switching. Seems like more than 3db.

No one was on the 1303z pass but if you are full duplex, you can always talk to yourself. I had good copy with 10 watts and your 13T Helix all the way down to 1 degree (my best direction, southwest). The only thing more power and a bigger antenna would achieve would be to overcome the radar interference. No radome on the antenna; we'll leave it this way over the winter and see what happens when there is snow and ice.
