Re: I need a V3 or V4 uBitx board.
I think groups.io is your best bet. Steve has a poll going now, asking if there is interest in a new run of boards. If you want one you should join the group and respond to that. I may jump in there

Re: RFI from uBitx TX after AGC and other mods installed
Rowland, Check to see if the ground at the center of your new receive RF point is good when the board is unplugged. If it is, then unplug the AGC board and jumper the two outer pins of that RF tap. It

Re: Keypad for Raduino...?
Hi Jack. The "electronic code lock" keypad approach works great if you have lots of I/O pins available. But where I was using an UNO, I was quickly running out of I/O pins. So by using the analog

Re: Keypad for Raduino...?
I don't think I'd use an analog approach to it. I'd use something like: (https://circuitdigest.com/sites/default/files/circuitdiagram_mic/Electronic-Code-Lock-Circuit.gif) You can find code at:

Re: Keypad for Raduino...?
Hi Arv. I used a similar keyboard for a Scalar Network Analyzer I built. (Before I found out about the PHSNA :-) It turned out to work very well. I did run into a few issues worth mentioning. Make

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: I need a V3 or V4 uBitx board.
