Good afternoon everybody, from Louisiana. I have the QMX rev. 1 low band, which has functioned flawlessly since its completion, and *still functions correctly* hooked up to a PC running WSJTX.

I have recently gotten a HamClock bundle (Inovato Quadra flashed with Debian {which I've never used before}) and I can decode just fine, run Putty okay, etc... except for transmitting. When I attempt to transmit FT4 or FT8, the program shows a brief flash of one dot under VFO A indicator, and brief output on the power meter before killing the transmission and switching back to AGC meter (less than a second).

I know the FW_17 manual says that this is likely a muted sound problem on the computer itself, but I have everything turned up to maximum, input registered to QMX input and output on QMX output. Sound is all the way up.

Ideas, anyone? I should note that this is my FIRST debian based project and I am NOT a programmer.

Thank you in advance, AD5MO.

Addendum: everything *that I can see from the desktop* is turned up. Nothing will be taken personally if someone asks if I checked "x" "y" or "z" boxes, because I will be there first to say that I probably didn't, or thought I did and forgot about it. Thanks!

WSJT-X also has a vertical slider for TX power over on the right hand side/bottom. Is that turned all the way up? (I hope that’s where the slider is… I’m picturing it in my mind.)

Yessir, that's all the way up top, first thing checked!

Have you tried increasing the Audio gain (dB) in the configuration table? You can access this in terminal mode.

No, I did not. I'll look into that as well. It may be Sunday before I can fiddle with it, but I'll post my results here. Thank you!

She lives! It was plain, old, uncomplicated, simple RFI. Clipped two ferrite beads onto the coax, and another two onto the USB cable, et voila, JS8 and WSJT-X work just fine. Thank you to everyone who contributed help and hints, and I apologize...an Extra really should have known better!

Side note to anyone who wants to use JS8Call, reduce minimum samples to 1 from 480. I don't know if the rise and fall thresholds really make a difference, but 10 minutes of playing around this morning before work led the to reduce those numbers from 80 and 60 to 60 and 40, respectively...it seemed to make the radio "hear" what had previously been a blank waterfall. Made a few contacts after that before my paycheck called to me...

73, see you on the air!

Awesome, glad to hear this.

How are you finding wsjtx on the Quadra? I got it working before (though with a different radio) but to me it seemed it was barely able to keep up with the decodes and many times was too late causing a reply tx to get skipped till the next frame. I eventually dropped it in favor of the pi 0-2 which has a bump up in horsepower over the Quadra and never misses. But it's been a while and maybe I just need to repave it.

I had the same problem this morning, actually. I'm looking into increasing decoder speed any way that I can...I did find that I should not have had the AGC on (I did) and I should have had the audio gain lower than it was (I had to turn it UP for JS8Call). Apparently there are other decode speed options in WSJT-X, so I'm going to try those. Additionally, I had the Quadra running off my tenuous phone Hotspot to keep time, while waiting for my GPS dongle to come in...since Conky is running to keep the time accurate regardless of the input, I assume that some processing will be freed when it isn't relying on NTP but using direct input.?

What was your setup?
I may end up running a PI variation headless off my tablet eventually. The Quadra was cheaper and appealed to my wallet XD
