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.

Re: Just downloaded SDR UNO 1.13

The LO frequency is set at the point of the main waterfall where your cursor lies when you click Play. To change it, put your cursor in a different spot before you push play.

Re: Use SDR while transmitting

I'm using 5 watts and the AGC is manual. I really want to be able to use the RSP1 as my main receiver.

Re: Use SDR while transmitting

I am using an automatic QSK antenna switch so I can use the same antenna between my transmitter and receiver. The switch mutes the audio output from the computer and attenuates any signal coming back through the receive line by -80db. However, the SRD1 still desensitizes and hangs long enough to be ...

Re: SW Recommendation(s) for Newbie

Martin makes a good point. They don't use up much resources, so download and try them all. Some take a little more playing around with to get the results you want and some do some things better than others, but experimenting is part of this technical hobby. - Daniel, W2DLC

This thread may help: viewtopic.php?f=11&t=2074
Also, there are places in the Main settings INPUT and CAL tabs to adjust the LO.
