RSP2 with hardware frequency tuning wheel

Postby hb3ydh » Mon Sep 04, 2017 6:49 am

I am a newbie with RSP2Pro and like it eventhough I have not yet found how to open the 3 or 4 windows at once. That would be nice.

Beeing not a fan of frequency tuning with a mouse, I am wondering if it would be possible to use with SDRUno a TuningWheel from Griffin Technology (https://griffintechnology.com/us/produc ... -keyboards) which they build and sell as <Powermate USB>. I.e. Bonito sells it for its Radiojet 1305P for which he just names the Griffith driver with its hardware. Griffith does not supply any more driver other than for MAC, but the old driver for Win7 should be ok.

Thanks for any feedback.

Yes, it is possible to use a Griffen Power Mate with the RSP. I've successfully done it several times.

BUT

In order for it to really work well - i.e. little to no jerkiness, smooth tuning with no pops etc., you must use HDSDR as your SDR program because as far as I know it is currently the only program available to us which properly implements the necessary keyboard shortcuts for use with the Griffen Powermate. SDRUno and SDRSharp are not really set up for it and will be popping & the spectrum displays on both programs become jerky when tuning with the hardware knob. Not sure about the SDR Console software because I haven't tried it with a hardware knob.

Using HDSDR, it is easy to set up with most any hardware knob which allows the knob to emulate keyboard shortcuts. What I did was to simply configure the Griffen Powermate via its own software to emulate the up & dn arrow keys during rotation which then tunes the radio :).

There is also another alternative if you don't mind a bit of homebrewing - remove the electronics from an old USB mouse and connect a rotary encoder to same. Turns an old mouse into a rotary knob :).

Thanks a lot for your detailed explanation.

For the moment I do not want to install HDSR. I like your idea of transforming a mouse electronic. I have many mice "in stock" as it took me many to find the ones suiting me the best - hihi. After it would work, making the mechanic in aluminium to look similar the Grifin Powermate is not a problem here, a nice project.
