Also, re: PTT output - PTT doesn't output when in CW mode when keying with an external straight or paddle key, so it's not a matter of CAT control being the culprit.

I just finished my QMX this morning. Inspected the boards and solder joints. Loaded the FW#14 all went well until I restarted the QMX. The display had miscellaneous numbers etc. I posted on the FB

Here is a screenshot of proper Radio config…

Thanks Alan, thats what I went with, the QDX and case have been ordered. Its familiar, in stock, and ships without delay. Ron a few callsigns since 1970 "Alan G4ZFQ" <alan4alan@...>

Just been having another play but actually on air this time and it just reinforces how much better the keyer is.? Very few bad dits or dahs and it is mainly truncated dahs and mainly the first dah in

Same issue for me with the QLG2 most of the time. I did have one successful transmission, followed by many unsuccessful transmissions. I changed to a different GPS and on the first try it worked. this

I'm trying to connect my QMX to a Raspberry Pi Zero 2W. ?I have the official Raspberry Pi OTG usb micro B to USB A lead https://www.raspberrypi.com/products/micro-usb-male-to-usb-a-female-cable/ I'm

Here are three screen shots. I am using Kenwood TS-440S (don't have TS-440 in drop down). I see the QMX transceiver in audio input and output dropdown and am using them. And all is see in the main

Hello there was a posting in this group warning from using a USB-C PD Decoy with the QMX because of possible damage due to the voltage ramp accomplished by the PD Decoy during startup. I include a

Thanks Alan, its something I'm familiar with as its what I'm using for my 60M beacon. Its been running 24/7 on 12V without a glitch, but lower voltage operation will be less stress on me :-)

Ron, I'd say the QDX with WSJT-X/ Rpi. Build for 12 volts, run at 9 volts or less. 73 Alan G4ZFQ

Thank you Andy, this is very interesting as it is a solution to another project I wanted to do, remote VHF and UHF beacons for antenna evaluation. As I'm very very stretched thin wrt to time

The inability to send CW after checking the SWR is a known bug and is on Hans’ list to address. I discovered the same thing and reported it several weeks ago (before my QMX decided to refuse

Also don't forget the rfzero, just add a 1w amp. I have used both a U3s and the rfzero and the latter unit is definitely better. Andy. -- The universe is made up of Protons, Neutrons, Electrons but

I have the U3S, QCX+ (40M), and a QDX (currently the WSPR beacon on 60M for VE8TEA). And their are other makes and models of WSPR beacons. Likely at my own expense I'm looking set up a couple

Barb I had wondered that. I wonder if there is a rumour going round? On Ebay I see "BS170-D27Z N Channel MOSFET onsemi UK Seller" He says "These are not to be confused with the many similar devices

I have some BS170s presently purchased from a Chinese supplier. Clearly marked BS170. Having read this thread I decided to check. The pinout is S G D. Thanks for the heads up on this one.

Hi Bryan, the common mode current issue was also on my mind, but on the other hand I really wanted to connect the antenna directly to the QMX to make everything as compact as possible. I may go out

Thats cool. yesterday someone posted a Qrpbuilder vertical antenna like that for 40&20. So I grabbed my junk box and built one like it just for 20m. I used wire for the element but it works hanging

There are ready made usb-pd to 12Vdc cables available on aliexpress for just a single-digit dollars, shipping incl. I guess I'll give it a try. And yes, the pd capable power bank is needed for
