I am integrating my uBitx into an old HA 350 receiver? chassis. It has a band switch on it, so I want to program A7 to read the switch. I downloaded several different versions of code to find a good

In case anyone sees a similar issue, I took me a bit of head scratching to figure out what it was.? Add to that the random nature of it, more than one cup of coffee was consumed. Either K1 or K3 has

One of the easiest ways to do this might be to use a I2C expander configured something like this board from Microchip https://www.microchip.com/DevelopmentTools/ProductDetails/GPIODM-KPLCD You could

I have exactly the same situation with mine. I hear my voice loud & clear from the speaker, it's like a PA system. It's Kees' kit installed like the photos...a three pin header, center to ground. The

The transmit LPF filter relays only get energized when transmitting. There is no such band switching required when receiving. A very easy fix for that, let's ask hfsignals to rename it version 200.

I've got a black dial phone from perhaps the 40's. in the basement somewhere. That would be very cool to have as the UI into my uBitx. Won't want to get just too aggressive with the debouce.

Oh I forgot.... Should I hear relays switching when the band is changed via the encoder? The band switching function doesn't seem to be working either.....?? because it's?? FW 0.2?

My unit came with firmware version 0.2! :( Why is there such a low revision in it- just to get it working??? What is the best firmware available for it today and where can I find it? I tried adjusting

Jack But......I thought this problem WAS a nail! 8-) I did try 4 different keypads that have resided in my junkbox long enough to have accumulated some dust and maybe even corrosion. You are right,

That whole idea of using voltage to determine keyer state makes me nervous. Even something as simple as corrosion on the contacts can make a difference. Take Field Day. Some CW operators bring their

Hi Don: I mounted my K5BCQkit? board as shown in Kees photos. AGC appears to work. I do not have an O scope. Alan

Jack I did consider that approach, but my original intent was to use the minimum number of Arduino pins that could still support desired functionality. This should open up pins for doing much more

Alan, How did you mount yours audio gating board? Where did you ground it? And are we talking about the K5BCQ kit on yours, too? Since it is not distorted I would almost bet that Q3 isn't turning off.

It seems the easiest method I've heard anyone use I refer to as the RCA method. It's what the techs at the RCA service centers used when they had to replace modules on the TacTec hand helds. Cut the

Mark N1VQW I built a similar SNA, but control it via USB/tty link from a Raspberry-Pi. The keypad idea of using a single ADC input to decode keystrokes seems intriguing to me. This morning I set up

Hi Joel, can you tell me the number designations on the relays that you keep in supply. I may have to make a swap out on my uBitX board. Thanks Guy N7BIR

Don: I have a similar problem only I have not installed the RF gain control. On SSB phone transmit my voice comes out of the speaker loud and clear. I find it strange the audio amp / speaker are not
