Ron thanks for your reply. Yes, I did see +5VDC on pin #20. I will check tomorrow for continuity as you suggest. I'll post again with my results.

Hi Ernie, since I wrote that procedure, I take full responsibility for an obvious mistake in it and will send a correction to Hans tonight. That was supposed to say pins 7 and 20 (not 21). There will

0v, 4.8, 5.8, 6.6 Which caused me to go ouch. Using the center pin on the voltage controller chip I read 12v and 6.6v there. -Mark KA7ULD

Disregard the last. It does save the freq cal, just not the clock, which I dont need anyway for basic cw work. Thanks for the help everyone. Truly appreciated. Bryan, n0luf

Yes the ground if the same for GPS and rig.

Robert, Thanks for that. Okay. So connect it all and then turn rig on. Shut it all off and disconnect GPS? But....when I shut the radio off it looses both the clock and the freq calibration. How will

Rich. Thanks man. I got it calibrated and clock set. But...with the ground coming from the Paddle side the unit would not power up until I connected both. I suppose it would be safe to connect the

I would not hot plug anything into the radio.

Well, the way I do it and I’m not sure if that is the correct way is to turn on rig, connect to dummy load and the just plug in the GPS to paddles. Since my GPS is built into a clock, it is always

I have just completed my second QCX-Mini this one for 20M. Upon power up the display was one (1) row of blocks. In looking at the troubleshooting procedures by Ron WA7GIL, item #2 IC2 may not be

Thanks for quick responce. Okay. Is there any connection sequence? Can this be hot connected (with radio on)? In any particular connection order? Sorry to be such a dunce but I worked hard getting

What Rev of the board do you have?

Bryan, you do need to connect the sleeve to ground on the paddle side. It is normal for the rig to tx briefly and that’s why Hans recommends putting rig in “practice” mode. Rich

I am not clear how to wire this GPS to the radio and could use some confirmation. Here is how I have wired it. Using the 4 pin connection on the GPS. PTT jack Phono Tip (+5V) - GPS 5V Phono Sleeve -

Thanks Julian, i haven't stuck an SWR meter inline on the QCX, but I will do. I'll follow your proposed course of action too and thanks for that. I'll keep the group posted. Incidentally, from day one

Keith Plenty of evidence here of my own moments, who knows maybe even one or more for each project. We build, we stumble, we conquer, we tickle the ions with all the silicon integrated. See you on the

Yes nice data our appreciated designer also knows effective light weight packaging that many of us have marveled at. Reminds me to give the 80m plus some air time, used the 20m mini last week. Enjoy

I have a special boot I use to kick myself in the butt. You are welcome to borrow it, but it's had a lot of use.
