Batboard

good afternoon from sunny melbourne, australia

I have a little project I need some direction on. I have 2 GM300 UHF 465-495 radios and a CES Wireless RM20 Repeater Maker.

The RM20 has the ability for 4 seperate PL tones.

From the RM 20 Manual
Pin 5- CTCSS TX
If CTCSS is to be used on the repeater system, this connection must be made to a suitable tone injection point in
the transmitter. Consult the manual and/or schematic of your transmitter for this connection.

Pin 6- TX Audio
This connection is normally made to the transmitter microphone high input.

Can I simply tie Pin 5 & Pin 6 of the RM 20 together and put them onto the Mic input on the 16 pin accessory connector ????

If not, can someone suggest where the CTCSS TX point needs to be found on the accessory connector ?

Thank you in advance
Mike

Connect TX audio from the controller to the Pin2 Mic Audio In on the GM300.
Connect the CTCSS TX to Pin 5 Flat TX Audio In on the GM300.

Works like a treat.

For those interested, the RM-20 Repeater Maker from CES Wireless is fantastic with Gm300's configured as a repeater

Thanks for your Help HumHead
