Thanks all! There's a ref cal on the K3s. I ran through the procedure for that using 15 MHz and rechecked on 10 MHz. Seems this was quite a bit off. Now, not only is it lining up on WWV but also any CW signal I select lines up very closely between the marker on the P3 and a 600 Hz marker on fldigi with the sidetone set to 600.
A thing I noticed. When making the adjustment on the P3 the offset would be different for different signals. 15 MHz was 263 while 10 MHz was 210. So there was no one-size-fits-all adjustment there. On the K3s, I adjusted for 15 and everything came into sync including the P3, which now reads 12 for the ref adjustment and is consistent across a number of signals. Learning more every day. And liking it more. 73, Kev N4TT On Tue, Jul 23, 2019 at 2:38 PM Joe Subich, W4TV <[email protected]> wrote: > > On 2019-07-23 12:47 PM, Alan Bloom wrote: > > Also be aware that the center frequency differs depending on mode. > > The P3 *should be able to account for that* by using the FI get: > > > FI * (I.F.
