GM350/GM950 test lead and tuning
Posted: Tue Mar 20, 2018 6:02 am
Hi all.
I'm tested a GM950 2m radio that showed it's about 600Hz off.
I would actually like to tune it, but I don't have:
- Test cable GTF-376
- RTX4005/GTF180
And the radio is with a HHCH, so rear programming only.
I do have the RLN4460 test box, and what goes with it for waris series.
As for programming, I've used the GTF377 front-to-back cable with a normal mic-programming cable
Ideally, I would like to add a D25 splice to the GTF377 that would connect to the RLN4460. For this, I would need the pinout for GTF376 and the adapter "Round to D25" - the latter schematic is available on batlabs.
I also opted to purchase an GTF377 - but there just aren't any available. And I'm not inclined to spend top dollar, as I'm going to sell this radio.
Alternatively, I would purchase a RKN4083 and modify my homebrew cable to some frankenstein that would allow me to do what I'm attempting
Best regards,
Martin
