Re: S2 TX



Hi Michael,

That's good, .. from observation yesterday I made it 2401.31724 (without
Doppler) with my rx conv, ... so good match, ... much better than the
2401.322 to 2401.328 that is widely quoted.

I kept adjusting the non-Doppler freq until calculated RX freq with Doppler
matched what my radio dial said, ... all in real time so I think the value I
have is good +/- errors in my RX conv.

Many thanks
Paul, VP9MU
