RE: AO-40 passband back on



How many dB LEILA  is below MB ?

The S-meter is not too accurate of a tool, especially on TS2000

I guess with a linear uplink at bad squints at peaks it hits
much earlier than the signal appears at 10db below the beacon...


My signal was at S2 on the S-meter while the beacon was at
S9 and I triggered Leila...I'm using a home made cross yagi, so
it looks like I need to work on improoving CP ...
