Re: Proximity to computer

It also depends on the construction of the computer. I'm getting a spike every 17KHz that comes from my computer. It gets worse when I disconnect the power supply, and it seems to be coming through the antenna line because it goes away completely when I disconnect the antenna. I can significantly re...

Re: Receiver desensitized

Did you try using the notch filter to notch him out? Also, there is more than one AGC control. I don't even turn on the LNA on the HF bands and I set the base AGC level in the EX control window to about 90, but will move it up and down as necessary. Sometimes I also turn off the main AGC and manuall...

Re: sdruno/sdrplay/laptops

I saw in another thread that someone mentioned that some USB 3.0 ports are non-standard and can cause problems. Try using SDR Play through a hub.

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...
