Cross band MTR-2000?


 

Has anyone tried, or know, if you can take a VHF MTR-2000 and replace the VHF receiver with a UHF receiver and if it works? Maybe you have to edit the config file? If this works, it will solve a problem for a local amateur radio club.

I doubt you can do that with an MTR 2000 but you can with a Quantar - in fact a Quantar can have 2 receivers of 2 different bands at the same time.

I don't believe the MTR2000 SCM (System Control Module) will allow for
that - it would probably error out.? Once you set the band in the SCM,
it expects to see both TX and RX frequencies within the bandwidths
allowed in the software, so hacking that would probably also fail.

You could put a block converter in front of the VHF receiver.

Many years ago I heard of a voting system that used a number of VHF to UHF crossband repeaters as satellite receive sites. They all talked back to a hub location.? At that location they used a single UHF receive antenna feeding a preamp and a Down East Microwave block converter.? It converted from 420-430 MHz to something like 40-42 MHz or 42-43 MHz.? The converter fed a restive multicoupler that fed a number of low band Maxtracs and those fed the voting panel audio inputs.? I forget the frequency range, but i do remember that the multicoupler had something like 14 db of insertion loss...?? The reasoning behind this configuration was that back then 420 range radios were rare, but 36-42 Maxtracs and Radius were readily available and cheap...

I have no idea if Down East (or any other company) is still making block converters, but if so that would scratch your itch.
