I'll second that, my 3S and QDX are working perfectly, did 13 colonies with just the QDX this year. I received and finished a QCX mini yesterday and my only complaint is that it went to together TOO

We've got a warehouse full of this stuff! :-D https://vcfed.org/vcf-museum/ We're trying to figure out the 1960 Bendix Tube Digital computer. Not sure we'll get that powered up ad it requires

Wow someone still using CP/M and UCSD I cut my first computing teeth on Exidy sorcerer running CP/M S100 based system and other S100 system with varying degrees of storage including the old washing

Charles, I found this link on the web: http://www.oz9f.dk/wp-content/uploads/2020/02/ATU-100_Extended_Board_User_Manual_eng.pdf Note that you need to put the ATU into configure mode for the buttons to

Charles, You are correct in assuming those pads are for the extra switches, the switches need to be connected between these pads and ground (and maybe debounced with a .01uf capacitor). The only

I also purchased the ATU-100 “assembled” except for the shell and front panel. I have given up trying to read the tiny drawings and the horrible picture that was supposed to be the wiring

Ryan, That's good news. The focus is something not right with the front end. Maybe the T/R switching section tests will show something. Thanks! --Al

Just had a look at the diagram: Bypass = RB5 = Pin 26 of PIC Auto = RB4 = Pin 25 of PIC Steve

Hi Charles My ATU 100 came with the buttons you mention fitted...I had quite a problem with the ATU misbehaving above about 50w, I cured this by bypassing both push buttons at the PCB connection with

Charles, Open a command window. Enter "format c". Load your preferred *nix distro. Problem solved. ;) 73 Jim N6OTQ

Charles, This has always been a problem. When USB audio is plugged in Windows assumes you want to use it so it makes it "easy". People are saying it has finally been addressed in W11. In most cases

Really love my QDX but what is driving me nuts is the way Windows keeps switching my default audio device from Speakers to the QDX. Even with settings configured for Speakers to be default audio

Yeah, quarter wave verticals really do poorly. My first test of my JPC-12/PAC-12 vertical with 2 raised radials for 20 and 40 meters with my 20 and 40 meters QCX-Minis with my then-new vertical: Now
