What is the relationship between default_hw_settings.ini, default _settings, hw_settings.ini and he_settings_v3.ini?? I have V2 sBitx running JJs v3.025. Trying to figure it out.? My power out

Thanks Mike, that's very similar to what I've got drawn up. I have an idea for how to add it to the radio, gimme a bit more time and I'll post on the discord and here to see if anyone is

Jeff, have you seen Gordon Gibby's notes on a project he did with reverse polarity protection?

Morning all, So I have 2 virtual machines withthe code for 2m and 6m. As my code is opensource and for hams to use I would like feedback . I tried to keep the code small and clean. as the first

Has anybody tried the "ideal diodes" Andreas is describing here: https://www.youtube.com/watch?v=1tQHjUYKQwI ? So far I am relying on my Anderson power poles being soldered correctly. :-) vy de

Great Concept: this should allow more people to concentrate on bite size portion to concentrate their talents as well as for users to learn how best to exploit the various features hidden within the

I've been playing around with a PCB design that uses a mosfet for reverse polarity protection. Diodes burn a decent amount of power, this mosfet is significantly less. It also has over volt

This code will also work on the raspi pico, went to a fast mcu for better perfomance, the virtual machine ie there for develoment.

so I have 2m and 6m code emulations , I have to add in memory storage , but I figure I would share what I have done. its more basic as mine will be for sota/pota and I dont seen the need for

Richard, I just found time to put the circuits together. I am more like a magazine editor than a writer. Plus, my business experience has allowed us to assemble a very low cost radio manufacturing

PS another diode the other way round feeding a small buzzer gives an audible alarm if the power is upside down :-) !!!!!

Another approach which I have not seen proposed is to switch the power to the radio with a relay with contacts of suitable current handling. The relay coil is fed by a diode so only comes in when the

Richard, The comparable radio with the Xeigu is the ubitx. It is completely usable out of the box. We do, offer replacements or refunds for non-working radios. I still think this is a matter of

It is an odd thing though, the Elecraft KH1 is a CW only radio, selling for 600 USD. Not really, if you add all the essentials, it stacks upto 1000 USD. Yet, they sell about 3000 radios per month.

Send me an email at vu3sua@... Will send some pictures.

I think the crowdfund could be the best way to check demand (for the assembled units). Set up a goal of 20,000$ (200$? * 100) and see what happens. If the goal is not reached the money gets back, no
