#qmx #firmware 1_00_017 AGC, S-meter, LPF sweep #qmx #firmware

 

@Hans,
Do you have any plans or schedule, for the release of the firmware? It's a little bit of a hassle for me to load a new one so it might be good to know in advance so I don't load the day before new one is coming...
Good job with that AGC!
 

The issue with the battery voltage display freezing when the CW decoder is on still persists in this version. Turning the CW decoder off brings the voltage display back to life but re-enabling the decoder returns the battery display to it's frozen state. This persists after power-cycling the radio.

Cheers,

Hi Pawel

Good job with that AGC!

Sorry I don't have any schedule for firmware releases. There are LOADS of things going on here all the time and it's hard to guess from one day to the next, when I might?have time for some coding and to prepare the next QMX release; and when it IS ready I always want to get it released as soon as possible. If I had any schedule it would either be a case of always failing to meet the schedule, or the schedule being so generous and relaxed, that I was holding back code for release, which would never be OK either.?

Anyway really the firmware update is so so easy...?

Hans, I know upgrade is easy, I've done that before ;) Believe it or not, my (yes, MY) problem is, that PC I use on daily basis is unable to write USB drives. Can read but cannot write. Unbelievable? :)? So firmware update means I gotta go grab some other PC. And that's the reason I'd prefer to know in advance.
No worries, just do your job and if I'm one version behind, that's no big deal.
 

QMX observations FW 1_00_017
QMX covers the 80m-20m band, but I don't use the 80m band, so I chose it for the 40m-15m band.
?
1.Setting japanese limits to ENABLED.
When transmitting at 17m and 15m BAND in CW mode, an abnormally large amount of current flows and the BS170 will be damage.
It works normally in Digi mode.?
I think this also happens with QMX Hi-Band Version.
Setting japanese limits to DISABLED makes it works normally.
?
2.In the case of CW mode in system config LSB, the RX frequency and TX frequency differ by 1.40KHz.
The RX frequency is 1.40KHz higher than the displayed frequency.
Normal when using USB in CW mode.
In digi mode, both LSB/USB are normal.
This is the case when CW-R is OFF.
?
When CW-R is ON and USB in CW mode, the RX frequency and TX frequency differ by 1.40KHz.
The RX frequency is 1.40KHz lower than the displayed frequency.?
The CW-R function remains OFF.
When CW-R is ON and LSB in CW mode, RX frequency = TX frequency.?
normal. The CW-R function is turned on.
?
In other words, if you want to? CW-R OFF in CW mode, use USB + CW-R OFF.
When turning CW-R ON in CW mode, it is necessary to use LSB + CW-R ON.
Do not use USB + CW-R ON and LSB + CW-R OFF in CW mode.
?
I would like LSB/USB switching to be enabled only in digi mode, and only CW-R ON/OFF in CW mode.

I have similar problems with FW 1_00_017 on 20-10m hardware.
When I enabled Japanese limits, it does transmit on 20m band but not for any other bands. It seems no RF signal on CLK2 but TX control is there resulting? large Id current on BS170 transistors but no RF output.

Here's what worked for me
I use 70db slope, 50 smooth samples and 15dB/s of recovery. That AGC works great for me!
Thanks a lot @Hans, what's next? :D?
