How to test a DIY counter and GPSDO

[Remco]

@mti: Super!

I try to fiddle with it. Although the Lars GPSDO does not output
the frequency, but I remember having read somewhere the LSByte of the
DAC (PWM) value is related to the frequency.

Lars' GPSDO is now connected to my Es'hail-2 (Google on it ; -) station
and is around 10 - 100x less stable than my BG7TBL reference, so I presume
I have to increase the PI-loop time constant.

However, I think after some tweaking (and also automatic filter/time constant settings)
it'll have the desired precision/stability.

The latest Lady Heather will monitor the Lars GPSDO, but has no direct keyboard commands for changing settings, etc.  You can use the !t (terminal emulator) command to do that.  Note that I don't have a Lars GPSDO and developed the support with Lars sending me data capture files that Lady Heather reads as a "simulation" device... someday I need to build one.

@texaspyro That is even more convenient!

Will try it immediately : -)

Edit: Tried it .. on my laptop I shows an unreadable flattened/squeezed screen/window
which I can't enlarge (?)

Edit2: compiled in on my Linux desktop system and the window (size) looks normal.
Now spend some time to read the user manual ; -)
