Re: Strange offset

You didn't really give enough info to diagnose the problem, but OK, let's try some things. First, I noticed you have VFO B selected. Try selecting VFO A. Secondly, in the main window, you have a button labeled OPT. Click that to get a drop down menu. Under that menu is a selection to calibrate the I...

Re: Audio latency and CW QSK

Well, changing the quality setting to high helped a lot, and I set my QSK switch to half break in. In that setting, it continues to mute the receiver inputs for about a second after the last key down. I made a contact with it that way last night and it worked OK. BTW, I installed the ASIO drivers, b...

Audio latency and CW QSK

OK, I've narrowed the CW transmitter overload problem to the latency of the receiver. Basically the QSK T/R switch does it's job before the signal gets through the SDRPlay, so the SDRPlay doesn't get muted before the next key down. I don't have any hang time control over the QSK switch. I installed ...

Re: RX-TX switch for SDRPlay

I have to keep qualifying my answer because the problem comes and goes. Anyway, here is another Transmit/receive switch kit I discovered today:

Re: Will SDR Play work to do HF Aviation Scanning?

There is a scanning plugin available for SDR# , but I don't know if SDR# is playing nice with SDRPlay anymore.

Re: Suggestions (or maybe some of these features already exist)

FYI, you can tune the LO frequency with the mouse wheel. It's slow because you can only tune in the selected increment, but you can change it that way by putting your cursor on the LO frequency on the waterfall and rolling the mouse wheel. The ZAP button will put you on top of the nearest, strongest...

Re: 3rd party Metal Case for SDR1

I solved the problem! Since the time I bought the SDR1, I've had problems with my QRP transmitter overloading the receiver, even though I have it connected through an automatic switch box. I tried all kinds of isolation techniques, and each helped a little with other types of interference, but not w...

Re: OK which of these antennas too use

Don't put the miniwhip on Hi-Z if it's designed for VHF or higher because the Hi-Z input is designed for 30Mhz and lower. It would make more sense to put the sloper on Hi-Z, but you have to make sure it's matched for Hi-Z. The Discone, I would assume is also a VHF-UHF antenna, so it can be on A or B.
