2970N2 project

zinger827 · Jan 15, 2017

Hi I bought a project N2 with no amp. I didn't get all wiring for the CPU and need to know what jumper wire(s) I will need to complete the hookup.
I see on schematic where they go but the J10 one has me confused like it showing going to the mic board from J10 then to CPU?
Is that jumper wire like 3 or 4 jumpers on it?
I'm also going to try to use it as a 2950dx since no amp and it does have the dual finals in it?
Also need to know what hooks to the open connectors cn604-605 on CPU?
Oh and missing the channel selector also the guy had a echo board control going thru ch. selector hole.
Posted some pics.
Thanks.

The transmit wire from pin 3 of the mike socket goes into one pin on the computer. Feeds into the CPU, not the radio T/R switching circuit. The mike keys the computer in this one, not the radio.

Another wire from an output pin on the CPU keys the radio's T/R circuit. If the computer feels like it, that is.

I'm at home tonight, but I'll check the diagram when I'm back at the shop and see if I have any pics that could help.

Might, might not.

Hi thanks. A pic would be great if can get one so I can see what jumper to use and where to put it.

Ok I got CPU all hooked up working normal now but I don't have Tx. I know it has a jumper from mic board but I don't know where they go or come from? Also don't know what jumper to use? Thanks for all that info Nomad.
