I have an APRS station on 144.39. I would also like to run my Packet station on
145.03. So I need someway to run both stations. What would I need to do? Can I
build what I would need? If so where would I find that info?
Thanks, Kevin

Assuming from reading between the lines that you want to use both stations
on the same antenna, get a 2 meter duplexer. The seperation between the 2
frequencies is 0.64 MHz. At bare minimum you need a notch (reject) duplexer
but a bandpass-band reject type would probably be the better choice.
Good advice.
The only thing that I would add is that you need to use good quality
equipment for the antenna system. This includes the duplexer, jumpers,
connectors, cable and antenna. When you have a situation where two
transmitters can be on the air at the same time on the same antenna
look in your mail box

The ability to program over-the-air, via phone line, or through the
optional RS-232 port was one of the big advantages of the ACC
controllers in the 1980's. This was a controller that was way in front
of the curve, but the cost was prohibitive for the average ham.

Hello Group,
I have a Mocom 70 with intact PA section. Radio is a [T73BBA1900BA].
The PA board # is [TLD8882]
The transistor chain is made up of [M9622], [M9624], and (4) four
[M9625].
I thought perhaps that the PA section would make a great 2m amp.
Is anyone interested? I would think the

Yeah but that's easily dealt with because you never forget
what you have programmed and it's always right every time
you program it.
