Hi Jeff, First of all, thank you for your reply — I really appreciate you taking the time to help! In my previous post, I was experimenting with different input voltages using a bench power supply

Hans, I set the QMX to "practice" mode whenever I want to disable the transmitter and use the QMX as a receiver only in CW, DIGI or SSB mode. This makes sense when I listen with a random non-resonant

Thank you Paul and thank you George. 73! de Bekir TA2RX 5 Nis 2025 Cmt 05:12 tarihinde George Korper via groups.io <georgekorper= [email protected]> ?unu yazd?:

Hi Bekir, With the supplied parts, and the circuits as designed, as the frequency increases the output will diminish. So far I haven't seen a post that shows otherwise. 73, George

The setup I used is in the image below: Power supply is from 3, 3400mAh 18650 Rechargeable Batteries in the Power Bank Box. ( https://www.aliexpress.com/item/1005006076485612.html ) Microphone was

I rather doubt that's true... If I understand, the differences in output between every unit have more to do with variations in the parts (the output transformer, toroids and associated caps of the

Karl, previously you wrote that " The signal is also present on pins 1&2 IC408 but not on pins 3,4, 12 thru 15" Has this changed?? This is proper switching - the signal being seen on both parts of

I seem to remember reading a post that when powered with 9V, QMX+ will give a steady 5W output on all bands, but I cannot find that message now. Is this true or is it my memory playing a game on

Hello Igor, some of your screens show input voltage of 12.8v. ?Others show 11.8. ?Is that what you see there? ?Is the supply voltage being reported inconsistently or are you varying it? also the

Just got mine from Erick for my QMX. Used a tiny hot glue gun spot to add just a touch length to button to make it easier to use. Thankyou @Erik Larson, The blue is nice, good choice.

Thanks, Stan. Will try.

It may work to turn down the agc threshold to about s6 or even lower.? My agc didn't often activate when I used the default threshold. I had the volume turned up to hear quiet cw signals, and so my

No, you misunderstand.? The power and SWR indicators should work fine in DIGI mode.? It is only the agc and s-meter that are not implemented. If your power and SWR indicators are not working,

A few more data points w/ power supply connected: Supply Voltage | TX Voltage | TX Power | SWR | 10.8 V ?| 9.4 V | 1.9 W | 1.18 | 11.8 V ?| 10.2 V | 2.1 W | 1.18 | 12.8 V | 11.0 V | 2.3 W | 1.17 |

Stan, you must be in Houston, because we have a problem! No matter the freq the signal is present on all L40X coils....there is a whole lot of switchin' not goin' on! -- 73 Karl KI4ZUQ

Hans regularly reads messages posted here, and puts the bugs on his list.? As far as I know such a list is not published.

I have a QMX (80-20) for 12 V that I built last year. It worked fine on FD, and was used occasionally since. A few weeks ago I was running it into a dummy load. Controlled by fldigi. Power was a

Take this one, it's the

?Hi Alan, I measured the voltage on the HC6 socket and found negative .1 volts on one side and zero on the other. All the sockets measure the same negative voltage in the instrument. This obviously
