CRT SS 7900V Turbo (latest version) Service Mode? (And more tricks)...

[BC Coyote]

I'd been fiddling in the menu in a moment when I'd be better being sleeping instead.

Uh Oh. Really no reason to be in the service menu as those radios are bang on right out of the box. As Shadetree said, some menu items require special equipment (ie: signal generator) to get them back to where they should be.
Be aware also that every radio is custom programmed, so many of those service menu settings are different from one radio to the next. Also, there are two different physical versions of that radio, and several different firmwares.
Good luck.

Yes, I'm aware of that. I focused my concernings on items with very different setting values.
Yes, these radio are good right out of the box. I was just trying to adjust the output power at the lowest position of the knob

Sorry, there's something I don't figure out about those settings which require a signal input. Once the ptt is pressed on those, do they wait for any command, or the input is read and stored right when ptt is engaged?

the input is read and stored right when ptt is engaged?

Correct, you have to inject the proper signal into the radio then hit the PTT to store.
It really is not advisable to play in the service menu without proper test equipment.
Best of luck.

It looks like now my rtx needs to be fixed then. I'd a reading of all the parameters, with a dummy load connected. All settings which read input signals would be zeroed

I'd not been very active on air during these Holydays, but I should say the radio is working as usual 'till now. Though I'm even considering to send it out for an accurate check, and re-alignment if needed.

Reading this thread I find some user being confident with service menu settings.
I'd be very grateful @Pez @13OP25 and others
having their opinion about what's discussed since post #116
