GTX800 Analog?

[emanuel32804]

Hi all,
I'm looking at getting some gtx800 radios to use in a mmdvm repeater. I see they can do conventional non-trunked, but are they able to do just regular, plain old analog? Does that still work if its in talkaround? The goal is to have the mmdvm output P25 into the radio and it would just transmit it as analog. It seems most mmdvm boards have trouble outputting analog, which would allow the radio to output P25. The other thing that I'm trying to figure out is the accessory port pinout.

Pin Number	Description
1	External Speaker-
2	External Mic Audio
3	External PTT
4	External Alarm
5	Flat TX Audio
6	SCI Data In
7	Ground
8	SCI Data Out
9	Emergency Switch
10	Ignition (+12V to turn on radio)
11	Flat RX Audio
12	General Purpose I/O
13	Internal Speaker or Ground or Sw +12V (see below)
14	Hook Switch
15	RSSI Buffered
16	External Speaker+

I see TX audio, RX audio, and PTT but I don't see any kind of RX indicator unless it's not something that would be obvious. Maybe GPIO or hook switch? Any thoughts?

Of course, if there is a different radio that can do 800mhz that you all think would be more suitable and accessible (cheap too!), feel free to suggest it.

Thanks,
E

Look at GP I/O pin 12, it may be configurable to be COR

I'll look into that, thanks. Any idea about the analog transmission?

Use the flat audio for TX and RX with the MMDVM.

Is there any additional configuration that has to be done though? I know in XTS radios for example, you select non-astro in the conventional personality.
