Re: [Elecraft] A question about HDSDR controlling SDR & K3 at same time
Depending on the stability of the oscillator in the SDR, the numbers you have now may be good, or may change. I have an early RSP1a and it moves around a good bit. I don't rely on it for any degree of accuracy. I think it is more temperature related than anything. 73 Bob, K4TAX On 2/20/2020 3:59 PM, bw...@fastmail.fm wrote: Thank you Bob!

In CW mode - HDSDR displays a close-up of a given signal on the lower-right. And at dead-center its spot on - and producing the 600z tone.

Thank you Bob! Yes I see it - its the "RF Front End + Calibration dialog box". And the "LO Freq Cal" I've got it setup correctly now Thanks!

Re: [Elecraft] A question about HDSDR controlling SDR & K3 at same time
You will need to correct the frequency errors using HDSDR calibration mode. There is a setting for each mode. It is in the Setup menu under input calibration.

[Elecraft] A question about HDSDR controlling SDR & K3 at same time
So last week with your help I got HDSDR setup to control both a RFSPACE-IQ (for panadapter) and the K3 at the same time. There is one behavior I haven't been able to figure out. I have HDSDR and the K3 both setup to output a CW sidetone at 600hz. In CW mode - HDSDR displays a close-up of a given signal on the lower-right. And at dead-center its spot on - and producing the 600z tone. But its then not quite spot on - on the K3 I've tried offsetting the side-tone frequency on HDSDR - thinking I just needed to shift it so that when the K3 is spot on - the signal will show up in dead center on the HDSDR signal window. But that doesn't seem to work. It still retains the exact same frequency offset between HDSDR and the K3 Has anyone seen this? And can suggest a fix?
