The Radio Information Board

Should only be 4 wires: shield, mic audio, ptt and off hook. is that right?
If so, what are the colors? Should be able to check the colors against another GE mic that we can
find the manual for......

I have yet to find the pinout, but have found that it fits the GE MLS radio if that helps any......

All I know is they are OpenSky digital.
I have uploaded a user manual and quick guide in PDF here http://depositfiles.com/files/2meu5ehax/

Well... There you are. Super Secret Squirrels have 900 MRKs on the hamband. Will anyone ever get the info
on how it's done???

Yeah,
My only thoughts were it must be a bad cap. I have some TK930's that had a bad
SMD transistor that would keep them from powering up - just jumpered them and had to
pull them power cord off. I suppose I will get my magnifier out...

I have lots of GE M/A-COM manuals, but not this one...
MM101984V1 Hand Held Controller Installation Manual

That manual should have those cables with fancy diagrams and pinouts...

Going to sell this radio to a local FF only to find out it is defective when changing the programming. The radio will power on then power off after only a few seconds or so - or it will power up fine until 12v is removed. Seems to need to have 12v removed for about 30 seconds before it will successf...

That's what I was looking for...

Many thanks!

I'll give that a shot. Any other suggestions? Is the audio PA located in the RF deck or the control head? Any details on its replacement? Audio PA is in the control head. "U13" Linear: Low Voltage Audio Power Amplifier; similar to National LM386N - 4. Amp is on the INPUT/OUTPUT BOARD 19D9...

Anybody out there know anything about reprogramming a Titan UHF radio?? Do these require an UV light to wipe the EPROM? Are the programming cables ridiculously hard to find everywhere else in the US? (I'm in KY, nothing here, at least nobody claims to have anything of the sort.) Any help or guidanc...

Looking for the Relm Micro-Com SM series radio mic pinout.

Trying to help a vol fire guy with a bad mic - I'd rather throw the radio away where it belongs (in the dumpster)
but I guess that's not an option......

I think I have it close, but I would rather verify with someone who knows for sure......

I am unaware of any mods for the 900Mhz MRK to the hamband. The Orion has recently been mastered, but I don't know where to see the mods for it. The YAHOO Group "GE" is probably the place to find out about both... Or "AR902Mhz" Motorola 900 GTX portable is the cheap way to go for...
