Re: [amsat-bb] AO-40 reception difficulties

Hi John,

Good eyes - my  typo.  8203.125 is what I meant.  Gives a 2100 mhz LO.
We did verify this on the bench, so I know the Icom is tuned correctly. 
And, I did get a signal on one pass.  It's just all the silence on the other
passes that bothers me...

Thanks,

Greg.
