MTR2000 is external 5/10 reference standard

Post by RF_Burns »

Hi,
I know you could order the MTR2000 with an external 5/10Mhz reference option, but it was only a few dollars... so I'm thinking that was to cover the cost of the external connector for the reference input.

So I'm wondering if the External 5/10 Mhz reference can be enabled on all of the units, regardless of whether you ordered the option, you just need to connect to the board BNC rather than one on the back of the radio.

Can anyone confirm this?

thanks

According to the Installation manual, the 5/10 MHz BNC jack on the SCM is where you feed in your external reference. You select the frequency in the programming software. The MTR3000 manual mentions that a short extension cable can be run inside the station to bring this jack to the rear of the chassis, but I didn't see that in the MTR2000 manual.

This is a standard feature. Nothing additional is needed other than a signal of the proper frequency and amplitude.

If you can have the station off the air for a bit, program it for either 5/10 reference and see what the front panel does.
If it takes the programming and goes into a fail state (red light instead of green) it's looking for the signal. Of course you can then put it back until you have a reference connected. If it stays green, then there is more to it.

I have 10 of these that are simulcast (5 and 5 on two different channels) and that is how they have acted when loosing reference.
