I profusely apologize.Senior moment? 30dB is the recommended level for sure. And I had read about the per band gain control in my initial 2 times through the Ops Manual. It just didn't

I placed an order for a QMX 5 months ago and, based on my position in the waiting list, I still have 2-3 months left to wait. Having read all the posts about key clicks and thumps I am concerned I may

The diagnostics in the terminal mode shows if the encoders are working

Is there a connection from ground to the middle pin of the encoder? Do you have an oscilloscope? If yes, check the signel at the left and than of the right pin related to ground when rotating. You

Glad to, Steve! Yes, I would really like to see some scope traces! In particular, I would like to see the stereo DAC outputs. That is sort of a fold-and-tear-here point in that if the signal looks

Thanks for checking the data sheet John. There's a big clue though in the fact that the glitch occurs both at the start and the end of a tone. More info could possibly be obtained by looking at the

Hi Greg According to the WSJT-X manual: "Use the receiver gain controls and/or the computer’s audio mixer controls to set the background noise level (scale at lower left of main window) to around

Re: slew rate, The Onsemi datasheet for NE5532 is self consistent showing a 9V/uS slew rate and a large power BW much greater than this application requires. I think the TI datasheet may have a typo

The QMX has audio output level settings in the configuration. Also if you use flrig to connect to the rig it has a volume slider which I prefer. 73, Cliff, AE5ZA

Let's take the core of this QMX with its software always getting better, put it in a bigger box, have 9 bands, real RF transistors to provide 15 20W and that can handle 14V from a 4S battery if

Still, no volume control on my new build QMX hi band?? Volume in ear phones is full blast and volume control has no affect?? Re- soldered connections, no change?? I think pot is bad.? Anyone know

Interesting. My issue is relatively low input audio volume showing in WSJT-X; just a bit below 30 dB. Though WSJT-X shows that as 'green' and I'm making contacts OK. My 4 other rigs and SDRs have to

Thanks John.Good info to know. That PA-50 is getting more popular I think. Greg KI4NVX Greg Yahoo Mail: Search, Organize, Conquer On Sat, Mar 16, 2024 at 10:41 AM, john terry<n0jtqsl@...>

Hi Greg The PA-50 does have manual band selection, but this did not prevent SWR trigger. There is also automatic PTT function which would still be active and likely still the problem. There is

Just completed my Rev 3 Hi band QMX. Rx sensitivity is okay and Tx power out is very good on all bands. Probably all needs a bit of tweaking, but pretty good so far. However, there is noise present

Depends, Is there a foil trace already between those two locations, if YES? then no need to,? If NO, where does the empty hole go to? Joe WB9SBD . A Contest 40 Years in The

I went through multiple USB cables as well, until I landed on the right one.? Most of the USB cables that come with devices these days are not wired for data transfer -- they're wired for charging

My clicks sound exactgly as Brain Swann's recording. Just unusable for more than a couple of minutes before the headache sets in! Daimon. G4USI

Torsten, there is a DC connection from the BNC center pin to ground through the SWR sensor transformer. This is a DC short, not an RF short. It is normal. Ron

Greg, I am experiencing the same "blasting high" audio in the headphones when selecting Digi Mode. The "Audio Attenuation" settings in the menu affects only the headphone level while the audio
