[GreenKeys] Problems on Proposed Autostart Frequenfy 10.133

[Bob Camp]

Hi,

Sounds fine to me. We only need about a 300 Hz wide hole to squeeze 
through. I agree that fighting a strong station a few KHz away can be a 
pain but it should not cause an auto start problem.

If we are going to use conventional SSB radios then we need a bit 
bigger hole. It sounds like finding a 2 KHz wide clear space may not be 
all that easy .... 30 meters is about the most empty band I know of and 
what you are finding makes it look more and more crowded with each pass 
....

Keep up the good work!
