The step sizes can be changed by a right click in the RX window while hovering over the frequency digits. A menu will open with many choices. I tried this a moment ago, made some changes, closed SDRUno, reopened it, the changes appear to be saved. They were stored to the ini file. They may be lost i...

There is a LO at 120 MHZ.

If the above is the theory of the workings of this antenna, then a bigger capacitor will have a bigger aperture and couple more "E" field, thus more signal to the receiver.....

You would then need an SDR that could handle the increased dynamic range, the SDRPlay class cannot.

Today I connected the tracking generator to my scope. Tried all the functions with Arduino serial monitor. Set up a sweep and observed it on the scope. I could not get a response for the Connect command. Could this be the issue with Spectrum Analyzer? According to the user manual the tracking genera...

Spectrum Analyzer is primarily test and measurement software. It's particularly helpful in the characterization and design of RF filters.

Thank you, Bob.
Got a response to the version command with serial monitor. 'Newline' or 'No line ending' must be selected in the drop down box in serial monitor.
'Carriage return' or 'Both NL & CR' won't get a response.

Bas, I took your advice - compared the two G5RV's (yours and Hackgreens) and the Twente sdr : http://websdr.ewi.utwente.nl:8901/ which uses a miniwhip. I'm not going to make any further comments. Make the comparison for yourself and report back.

Bob:
There was a discussion about this a few weeks ago here:. https://www.sdrplay.com/community/viewt ... =12&t=4336

You've made more progress than I. I can't get the mega2560 to answer when I query it with the serial monitor. Rx flashes but no TX.

There are no s1b files included in an SDRUno download.

If you have an AC voltmeter measure the AC between the chassis of your SDR (when it's connected to the PC and the PC is running) and (with the antenna disconnected from the SDR) the shield of your antenna cable. You may be surprised what you find. I was. I measured 60 Volts AC
