Connecting two mtr-2000's

Postby tomsttsa » Mon Nov 26, 2018 7:01 pm

I have a VHF and a UHF MTR-2000's for our radio club. Has anyone connected both together using j7 or the system connector without a controller?
thanks Tom

It's not wise to connect 2 radios together without some sort of interface. You will not have any control over audio levels and it is a must to set the time out timers in both radios to keep from locking up either transmitter.

There have been a number of people pedaling interface boards just for this purpose. Been a long time since I have looked into it as I use to work for a company that made radio interoperability gateways. But those gateway products are way beyond what you would even consider spending on what your looking for.

What radios do you own?: Too many for the time I have.

Are you wanting to connect them as back-to-back repeaters? What comes in VHF, goes out VHF and UHF, and what comes in UHF, goes out UHF and VHF?

I've done similar with a Quantar and a Mastr 3, using the wildcard tables on the Quantar and COR signal on the M3; and just tie the wirelines across to each other. Worked slick while we waited for that dept. to get its act together & buy new radios all on UHF.

Just took a little playing around with wireline levels, initial levels weren't too too bad.

The VHF is our club repeater, linked on UHF to 2 others. I had thought that TTRC could provide remote control to disable either the UHF link or the VHf repeater should it need it. Actually, if the above scheme worked well, as a standalone arrangement with ID'er and all, then cat1000 could be linked to the system via a UHF link transceiver. Then the weather radio and the voice recorder could be local with echolink also remote connected to a port on the cat1000. Up here in Canada, access to repeater sites can be troublesome in the winter. ...anyway, just experimenting and trying to think outside the box,,,73 Tom
