Hans, Probably not. This sort of thing does have to be adjusted and interfaced to a particular radio. I could not build a stable VFO so used one of the PA0KSB design in a converted Decca Voyager,

Henning, this s something which deserves a photo! or two. It is a fascinating bit of history actually this whole huff'n'puff subject. Hans himself did something very unorthadox but cool, in using a

I agree, but I’ve checked it and checked it. I guess I’ll give it another once over.

Hi Rob Just looked at the Bamatech case and it looks like there is loads of room around the headphone connector, so guess that's not the problem, coincidentally the case is almost the same as the one

Rob, Seems obvious, although not obvious. Must be a bad connection, solder joint, fragment of wire/solder, something shorting together or on the metal? case.. 73 Alan G4ZFQ

Hi Rob Well my problem was that I got a crackle/scrathcy noise in the headphones as I pressed a button turned a knob or moved the antennae cable at the BNC socket. I never had it go deaf though. I

All,the second Version Arv mentioned reminds me to my Version which I build in 1972/1973? together with a frind of mine using TTL chips: a frequency counter using 7490 Chips + 7575 latches connected

I installed new caps, removed turns from L1, L2, and L3. I checked the voltages on the IC chip (IC3 I things). Never did figure it out. Based on the other input I’ve received, I’m just leaving

Yes, it’s in the Bamatech metal case.

Hi Rob Is your QCX in a metal case? If so I may be able to shed some light as I had similar experiences, If it is not in a metal case then I don't have any solution for you! Cheers Ian G4GIR Sent:

Many thanks to Greg, W7GA, for pulling my QRP sigs out of the mud on 14062 kHz, using my QCX-17 xcvr with external freq control...and external filtering :0) 72 / 73, Bill, N4QA

I had problems when I ran it on iambic A, but finds mine works fine on iambic B. Not sure if that helps.

No Hans I think you are being quite a realist in your comment about a huff'n'puff kit. Afterall there is a reason that Cumbria Designs no longer sells the X-Lock kit which I now wish to essentially

Based upon advice from many helpful folks here, I decided to leave well enough alone on the low power issue and I have my QCX ready to go with a minor modification that added a momentary switch to the

Plenty of FT8 sigs...even a few JS8 sigs on 20m right now using the QCX-17. The attached screen shot shows my 'app' ;0) and RBN spots of the QCX-80 and QCX-17 under external freq control. BTW, some

Hi Mike. I get that a lot when my rig, PC etc try to become part of my antenna system, especially when using an external 'amplified speaker'. Could you describe your antenna & feedline...and any audio

Hahaha yeah Bill you're right. But did you notice my callsign? A PTO is a new game for the kid after all the vxo stuff gets old. Joe -VE3VXO

Just finished my QCX 40 kit and it went together well. Came right up with good alignment and output at 12-16v. Problem is cw sounds terrible through the headphones/speaker. I get a loud click at the

Hi, I have a similar problem. When I change the keyer configuration to IAMBIC (A/B), it works sometimes fine. Alternating dits and dahs, next time it works well. Also it seems to depending on the

Once conditions had faded here on 5000 kHz late this morning, playing with the QCX-80 became less fun so, I unhooked the??Chameleon?interface from the QCX-80 and connected it to the QCX-17. WWV has
