That picture of a cordwood assembled module - tube included - took me back to 1965 memories. It's been YEARS since I assembled cordwood modules for a Boeing prototype * Data Storage And Processor

A couple of questions while trying out my new QMX. The S meter does not display when enabled. In CW mode when I release the key I get a significant popping sound in my earphones. Any suggestions?

Here is the ending to this story. After my trouble ticket?WJG-P5N-NY9B going unanswered (25 days in queue today and still not even an acknowledgment of receipt), I sent my QMX to a professional

I wish it was that easy. Mine is already set at 30. 73, Cliff, AE5ZA

That's my big question. Did I use faulty parts? I don't think so, but no way to test the caps. 73, Cliff, AE5ZA

I also have better power output on 20 with the cap swap. I think your problem lies with the PIN diode bias. The band configuration screen that Hans showed for mod #2, shows only 5mA PIN bias on 20.

I saw the title and wondered why Hans and Thora Hird got lumped together ? (UK readers will get the joke). -- - 73 de Andy -

Hans, I am a none non-US/Canada customer and selected TNT/FedEx Option. No Tracking number sent, no change in shipping status. Checked Spam Filter. Order number 72385, please advise on order status,

No it will not. It's more akin to the QDX hardware wise than the QCX. Think of the QMX as a QDX with the added functionality of the QCX. -mike/w1mt

Does the QMX require some alignment? I see the alignment menu but not sure what to do with it. I looked at the QCX instructions which show some potentiometers and a variable capacitor to adjust. The

Jim Campbell, The attached image was scraped from the Hackaday web site. It is an IBM flip-flop module using a dual triode vacuum tube. You probably saw these in abundance in your sleep! I first

And I had the opposite experience. My power went up with swapping the caps. Not sure what's different. -- 73, Dan? NM3A

will not recogize usb port.? Using Windows 10 om 64 bit machine, went to web page and uploaded drivers from manufacturer but they are 32 bit.? Any sources for Windows 10 drivers? Frank J. "Chip"

Steve, since you are an LTSpice user, I thought this might amuse you. It is the simulation I cobbled together to convince myself of the veracity of a low input Z for the Tayloe detector. Here you

Thank you. Will do. Mitch Nk3H

The Army (ASA) sent me to IBM CE School after which I maintained an IBM punch card installation in Germany for two years. After leaving the Army IBM hired me at their plant in Endicott, NY in 1960. My

Hi all Please note, quite a lot of packages were shipped today; non-US/Canada customers who ordered using the TNT/FedEx option have (due to a technical glitch) been sent THREE tracking number emails

I usually don’t get a first update till the package makes it to Mugla. Then it will appear stuck in France and then 1 or 2 days before it’s delivered it will be in the US. -- Colin -

I think they get deleted after a certain time period. You might try and contact the author of the post and get them sent to you. Good luck! --Al WD4AH

Heh, heh, heh... Some things are just good tools. -- Allison ------------------ Post online only, please no email.
