Re: I need a V3 or V4 uBitx board.
Steve always puts a lot of effort in getting the details right. His stuff always seems to operate cleanly with a comfortable user interface. I've heard good things about the Slop Bucket. An

Re: I need a V3 or V4 uBitx board.
A couple of months ago I built a Steve Weber 'Slop Bucket' 20 meter Transceiver that is SSB/CW. It uses a 74HC4053, a triple DPDT analog switch driving some transistors for T/R switching. It is sweet,

Keypad for Raduino...?
Hello I got tired of the minimalist input button scheme for my uBITX Raduino. Found this on-line, and am now working on code to make use of it for a homebrewed Raduino.

Re: I need a V3 or V4 uBitx board.
Not being a mechanical engineer, I'm awfully suspicious of relays. Especially cheap ones. K1 and K2 can rattle quite a bit when working CW. I'd much prefer to have K1 and K2 swapped out for solid

Re: Raduino consumption #ubitx #radiuno
Curious, I still learn new stuff everyday. I was expecting the REF pin to be high impedance. I powered up a spare Nano??from 5v with some other project's code it it. It draws around 17ma while the

Re: I need a V3 or V4 uBitx board.
Raj, When the trace burned it also burned only the TX side contacts on K1 which didn¡¯t alow RF to get to the receiver. Replacing K1 solved all problems, everything is working good now. Fortunately I

Re: I need a V3 or V4 uBitx board.
Glen, The filter relays come in and out when PTT is pressed. Saves a bit of current if you are using on battery. I just cut a track and wired the filter relays to operate during rx and stay there. If

I had similar problem some time ago. No Tx.? I could hear K1 pulling in but in actual fact it wasn't making contact. I replaced it with a different brand of relay and no problems since. But it does
