Re: Has anyone fully decoded the X9000 memory mapping?
|
Would love to see something arduino/pi based on these things.? ?I don't see a whole ton of Syntor X9000's in the wild -- I'm actually actively trying to liberate one from an in-service fire truck (I run a two-way shop) which I've been given full permission to do; however,need to remove the seats and parts of the interior to do so that require drilling out one-time-use pop-in retainers etc...? ??
I always wanted to find a way to remotely operate one of these with the ability to remotely switch between antennas (10M/6M) and Allstarlink gave me a good method to at least get the audio back and forth; however, the remote VCO control has had me using Maratracs (not a bad rig, but, limited to using BCD controls)? and I did come up with a way to re-program the radio remotely, and while that does give me *some* flexibility, it's not what i'd call 'agile' by any means!?

So, if mode 1 was selected, had a PL of 151.4 etc.... if I tuned away to a different frequency those attributes followed, being only the frequency was changing. It would basically require duplicating all the other features of the radio in hardware/software to take advantage of this method fully which is of course absurd.

I have the service manual and it appears it has a strobe line which basically thumbs through pages of the eeprom grabbing data for different modes. If it were fed data that we could dynamically update despite whatever mode (eeprom data offset) it's looking for then we could control it all.
