Need make RPT cross band for msf5000 and Maxtrac 800 Trunk

[taksin25]

I have Msf 5000 vhf base and maxtrac 800 trunk how I can make it for cross band rpt.

Cross-linking where one radio is trunked is very problematic (since trunked radios do not generate some of the electrical signals needed). We have been sucessful linking a UHF and a trunked radio, bi-directionally, using something like an N200 fron NIDA. (Don't hold me to the model number; I'm not at my desk.)

A cheap and working so-so way was voice activated switch from each rx. I buffered the mic input down to accept the rx line output from each tone remote, connected to each a UHF and 800 MSF's. So the UHF remote VOX would trip the tone remote to ptt on 800 , and vice versa. Luckily we're on a conventional 800 pair.
So far been working for one week now with little problems. Virtually RF proof since the remotes are away from the trancievers.

There have been previous trunked cross-band discussions. Here is one:
