...and it gets even more beautiful :-)
ONSEMI *used* to make BS170 that way... until end of 2021... from April 2022, they seem to follow the Fairchilld way (D-G-S)
So, when you buy a batch, I wonder what are the odds to get some from before April 2022, and some after..
Imagine all the mistery and excitement! :-)))

And if you thought: it couldn't get worse! Well, yes it can :-)
ONSEMI makes D-S-G BS170 :-)))
So, we have it almost all ways, D-G-S, S-G-D, D-S-G
Beauty!

Good morning.
Just a reminder to those of you who need to replace the BS170 in the finals (QCX/QDX/QMX).
Carefully check the pin order so you don't end up with transistors that have swapped pins (been there, done that...)
I had to replace the BS170 in my QMX and got a bag of BS170 from a friend that he bought online (China?).
The orignal BS170 for the QMX has the pinorder D-G-S but my new BS170 had S-G-D.
Unfortunately I did not checked this before solder them in. When I try to start the QMX the current went up way over the current limiting and the rig did not turn on.
After many hours of trying to understand what was happeing, I finally checked all transistors and found out the "reversed" pinorder.
I have now put in the same transistors but with the rounded side against the PCB and the rig is working again.

Re: #qmx PTT Control
#qmx
One more for the pile:
I have both QMX 80-20M and 20-10M versions, both are working like champs, excellent DX all around, running 014 firmware.?
But PTT isn't working at all on either version of the QMX, both on the "TX PTT +5V? and "TX PTT grounded"? (open collector, tested with a 10K pullup resistor to 5V) as enabled in band configuration. No output on either, not when transmitting from WSJT (with PTT configured for CAT), not from from by pressing the "p" button in diagnostics in the terminal interface, and not from pressing T either. It's just not working on either radio with pretty much identical behavior.?
I'll be glad when this gets fixed up. Meanwhile, is there any work-around? Any point on the board where we can pull a PTT signal from? What about the terrible hack of a current sensor on the QMX power input that triggers a relay? Might be more preferable than soldering to the board.
Coincidentally, I've also only noticed this as I begin to experiment with the 50W amp.

Just had a thought, you do have Minicom not running when you try to connect to Wsjtx don't you?

I'd use putty from the Pi.
Minicom is an old terminal emulater. Used it on 386 computers. It sounds like the way it handles end-of-line is not configured properly. If I remember correctly it can either send CR/LF LF or CR at end-of line. Maybe more. Also could be sending X-ON/X-OFF characters. If it's sending extra characters when you hit enter it will send you to screens you don't want. Can't help you with minicom. It's been too long.
Try installing putty and use it in serial mode.?

Re: #qnx #firmware ALPHA 1_00_015 called 00000000.zip
#qnx
#firmware
Hi All I've only had a chance to try 15 alpha this evening so apologies if this has all already been said.? I've been testing it by dabbling in the EUDX contest at between 24 to 28 wpm.? I use iabic B with paddles swapped:
- Sidetone seems clickier and somehow busier than it did on 14, not as easy to listen to.? I think this might be why some have commented that it sounds faster than set, It does sound fast but actually matches the RBN pretty well.
- It sometimes elongates a dit so e becomes t.? Seems to happen most at the e of the eul in my call.??
- Sometimes seem to hesitate then rush to catch up so the characters bunch up
- I don't think any of these anomalies happen at the beginning of an over.? Its almost as if some memory or buffer is getting used up then it starts to become erratic.? Is a memory leak possible with a QMX?? ??
- I've also noticed that the tune/SWR function is stuck on 80m.
- Sometimes it misses characters, it sometimes leaves a gap, sometimes misses then rushes and bunches the next character.??
I'm not very good at systematically testing and these issues are not happening all the time but will definitely happen a few times in a qso and once it starts happening it gets more frequent (I think).? Hope these observations help the overall gathering of info.? Good luck Hans! 73 Peter GM0EUL

Re: Request for QMX troubleshooting guidance
Lloyd,
With power off, check the resistance from TX to ground. Is it low/shorted?
Check for continuity from the MCU TX pin to the '08 TX inputs. Is the solder joint at the MCU pin good?

It looks like you hit enter once too often or clicked on the top item in the list "Configuration". What you should see when you click the top line in the "expected" view. I seriously doubt there is anything wrong with the QDX.

I attempted to ENABLE the TX PTT+5 volt setting and encountered the same problem as Adrian, YO3GFH. The ENABLE setting reverts back to DISABLE after leaving the terminal. Other settings such as Transmit (I DISABLED the 11-meter band) and audio gain settings did not revert to their original settings.

Re: #qnx #firmware ALPHA 1_00_015 called 00000000.zip
#qnx
#firmware
A few things I noticed after playing with this firmware today:
1. The CW-R and Sideband parameters still have no effect when altered via the System Config menu.
2. When entering the "Tune SWR" function, the frequency displayed used to be that of the current VFO setting. i.e. if the radio was tuned to 14.030 MHz, that's what the SWR tuning frequency was set to. Now, when entering the Tune SWR function, the frequency is set to the 80m band.
3. I tried paddles at 20WPM and the keyer still chopped the occasional DAH which, for an MM0 callsign like me, is a bit nippy.
4. The right rotary encoder debouncing still seems a bit off as it can sometimes take a few counter-clockwise clicks before the radio responds. This is most noticeable in the menu system. Not new to this firmware version though.
5. Straight key operation is a joy at 20 WPM-ish so I'm a very happy camper. :o)
Cheers,

Please say what do you mean by "confused state".
What are you referring to as the "normal" initial screen??
It isn't clear to me what you are experiencing that is a problem.
To do a hardware reset you need to open Putty and get to the config screens in the QDX.
The page you see in Bitcom is the main config screen in the QDX and it all looks normal.
Normally The TX Threshold is set to zero, but I understand it should work at the default also.

Request for QMX troubleshooting guidance
Hello, ? I have just completed assembly of the 20-to-10 meter QMX. Controls and inputs are good (firmware 1_00_014). Receive works very well¡ªgreat sensitivity. However, no RF output on any band. ? On key-down, CLK2 makes it through the XORs but not through the 7408. The latter¡¯s Tx inputs (2, 3, 10, 13) do not change state on key-down (The IC has power and the CLK2 inputs have signal). Thus there is no RF input to the BS170s. I would be grateful for a suggestion as to where to check next. ? Thank you, Lloyd (wa4efs)
