Hi Hans,

Slightly correction to my earlier email. When I tried testing your sequence, I started on 8.11 and not 8.13. I guess if I started n 8.13, I would naturally have to change the encoder to get to 8.11 or 8.12 and it would have worked that way even better.

Hi Hans,

Thanks for testing this. I had used a slightly different sequence.
1. Power is off
2. Plug in GPS
3. Power on
4. Go to Alignment 8.11
5. At this point, I start to see the weird behavior... For example, the QCX automatically seems to get out of the menu without me doing anything (showing VFO A and blank line underneath without me doing anything). But actually, I find it is still in the menu settings if I turn the rotary encoder back and forth 
6. If I go back to 8.11 then hit select, It doesn't seem to calibrate. But just now I was playing with it and turning the rotary encoder between 8.11 and 8.12, eventually it starts to calibrate correctly.

If I use your sequence I still saw my menu item appear to blank out when I hot plugged the GPS, but trurning the rotary encoder back and forth to 8.11 and 8.12 made it work.

So the behavior still seems different compared to T1.02b, where I never had the blank screen and I never had to turn rotary encoder back and forth. But anyway, I did get it to calibrate.

I had similar behavior on two different QCX. I didn't change fuse settings on either unit. Maybe I have noise eminaiting from my GPS connection? But I never saw this on earlier firmware.

Anyway, I can see how I can get it to work now. I like the new features you added in T1.03. keep up the good work!

Hello Gregg

I have just tried a fresh QCX-40 with a fresh 1.03 chip, and the frequency calibration worked fine. Steps:

1) Go to menu 8.13
2) Plug in GPS
3) Wait some seconds until I see satellite lock
4) Turn the rotary encoder one click anticlockwise to 8.12 and wait 6-7 seconds for the Sys Osc cal
5) Turn the rotary encoder one click anticlockwise to 8.11 and wait 6-7 seconds for the Ref Clk cal
6) Unplug GPS
7) Go to menu items 8.5 and 8.6 to check calibrations ran fine

If you have a different sequence of steps and it is failing please can you specify, so I can try that? 

Are you sure your fuse settings are correct (no divide-by-8 fuse etc)?

Has anyone else tried to calibrate their QCX crystal frequencies with GPS with firmware T1.03? It doesn't work for me. I get strange button responses, and the QCX never does update the crystal frequencies properly or at all. I reverted back to T1.02b and the GPS calibration works fine.

Thanks, Hans, for the info on the time display when in split mode with CW decode ON.  It really is just a cosmetic issue.  Not a problem at all.
