I wired up an adapter cable for an Icom HM-36 that came with one of my radios. I had considered removing the mic plug and installing a 3.5mm TRS plug, but I had the components in stock and this

Thankyou so much for your advice. It was indeed a short pulling oc101vto ground. I had a blob of solder across the capacitor C103, as shown below. With the short removed it nowvworks fine. Glad I

Andreas I believe you can also interrupt (cancel) an ongoing transmission by pressing the Exit button. I don't remember explicitly coding this for the KY command but, since the KY command internally

Hans, I think Doug is telling you to bump up the price of the QMX. Please remember your vow of poverty when you signed up as a radio amateur. Jerry, KE7ER

Thanks, Peter, but in my case no paddle nor key was attached and the message is being keyed sopely via CAT KY command. (Of course, no serious CW operator would do this, its only for noobs like me who

Hi Rick I've had my QMX+ since May this year and the tune encoder is simply worn out already! The push button and encoder are now flakey at best. Tuning HF works OK, tuning LF there are lots of

Have I misunderstood your suggestion for the second thing about interrupting a message?? You can already instantly stop an outgoing message by touching either side of the paddle. 73 Peter GM0EUL

The Tune Rate Cursor on my QMX+ has developed a mind of its own? For some reason it randomly cycles through the default tune rate settings. For example if it starts at 100 Hz , to 10 Hz to 1 kHz to

Hi Doug *It didn't do Dan Tayloe much good did it? No one who uses the Tayloe The Tayloe detector patent (expired) was filed by Motorola, and any license fees would presumably go to Motorola. As a

It's true, there is a long history of attempts at EER going back to Kahn's 1952 paper. But not not an awful lot of success, especially in amateur gear. In addition to the somewhat wanting Polar

Hi All, Please post a CESSB microphone for QMX+ and QMX available on Amazon with a wiring diagram. I know this is posted somewhere, but it deserves it's own topic ? Thank you, George K3GK

It does! Careful or you’ll get addicted!???

P.S. It's fair to say QMX/QMX+ is the first serious successful amateur radio SSB product USING EER [obviously] 73 Hans G0UPL http://qrp-labs.com https://buymeacoffee.com/g0upl

Hi Jerry Thanks for the nice explanation. Though QMX wasn't first... EER techniques are I believe, used commericially. In amateur radio: In 2017 the Polar Explorer was explained in a QEX

After years of reading about the filter and phasing methods of SSB generation, EER can seem mysterious and magical. ?How can a single oscillator generate all the needed component frequencies of an
