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.

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

Antennas like the OCFD, EFHW , really even a plain dipole will utilize the coax shield as part of the antenna's counterpoise if they can,? resulting in? RF in the shack, excessive noise pick-up, and

I have found that c50 is a bit microphonic, Am able to tap on it with a pencil and hear the tap. You might try it to see if the audio system is working. Have had the finals almost baking hot after

I would replace the LM386 they are relatively cheap, only issue may be time waiting to get one through the mail. If you have another audio amp, you could try connecting the wiper of the volume

Iz I suspect the inductor I used from coilcraft is at least as good as those in v5.? Q ~ 60 or 70 above 45 MHz.? I am contemplating a BPF based upon a T37-6 and a cap, but since we need rejection

I can try that on the short patch from tuner to meter or radio as I have LM240 there. but the line going to antenna is RG213. So I don’t have a clip ferrite that big.

I had similar problems when connected to an off center fed dipole.? i solved my issues with clip on ferrite on the coax going to the antenna.? That may work for you.? Maybe a ferrite between the

Hi Evan, Following your recommendation, I disconnected the 12V, 3A AC->DC powersupply and replaced it with a 12V battery. The humming noise is now gone but I can still not hear any of the signals

Hi Sam, I had a pvc air wound one too. 21ft of coax, but it was some real crappy coax so I took it off. I will try a better one. I was eyeing an inline choke, I was thinking of getting the my
