There is a uBitx "keying" board by W0EB on QRP Guys, might be relevant to your issue. https://qrpguys.com/ubitx-cw-conditioning-adapter 73 Jack KZ5A

We won't hold Gordon to making great advances with the acquisition of this nice tool, but bonne voyage on having the dBs and MHz's presented. (Okay he is welcome to further solve the v3 and v4

My fix for sticky controls I have had rf on the ptt on 20. SWR was 1:1 My solution was to put a choke on the mic wires inside the box. Can imagine that using a small toroid on the key wires would

Gordon, Congrats, you will learn a lot from an analyser. You will also need some attenuators and dummy load type powerattenuators. A 30db power attenuator rated for more than 100W will suffice even

The RasPi has heaps of GPIO too - I'm wondering if the likes of a 'zero' could take some of the 'control ' and display functions from the Raduino? Would/could I^2C tie them? There must be a heap of

Happy to say running shielded wires and making sure metal contacts like mic plug is grounding to case and everything else. I am not hearing any RF in the CW delay on my antenna.

There is piHPSDR too… Probably more common. It’s being used by most for the Radioberry currently. https://github.com/g0orx/pihpsdr

The RP is a computer with a 750MHz clock and a mega-munch of memory. That would be a possibility. The Raduino simply is not. Jack, W8TEE

The computer running SDR software could be replaced by a Raspberry Pi 3. It's quite small. Possibly a Raspberry Pi Zero, depending on what software you are trying to run. Jerry, KE7ER

Congrats for the nice tool! I have always asked myself whether one could also use an SA as a low phase noise receiver or at least a part of it.

Probably not. The Arduino family just don't have the resource depth or clock speed to do it. Jack, W8TEE

I have a different SDR that has it's own internal sound card circuit. Otherwise, it needs a computer running SDR software... Could that external computer be replaced with a Raduino?

I have a uBITX version 3 board for sale. It is complete, and has not been modified. It includes a Nextion 3.2" display, a 12v 5a power supply, an additional 5v regulator board that can be used to

Bo, I'd like to leverage your good work (aka copy). My current cheap sound card dongle is installed in my uBitx case. I put a easydigi between the dongle and the uBitx audio input/output, and I

Mike -- I burned up the included electret element, then bought 10 similars to replace it. Put one in a pill bottle with the tiny included switch on the side. Works grand. My QRZ page has a pic. If

How about links to the siglent and the spectrum analyzer that you mention??

I ordered the myantenna inline choke I posted. Theres a lot of good things said about so we will see. I have a 3 core 49:1 unun for efhw. before i had a 9:1 unun and a random wire. Had the same issues
