Using RF amplifiers with DMR and Openspot #dmr
You need an UHF amplifier with has FAST diode switching from receive to transmit mode and visa versa.
Because every 30 milliseconds the the amplifier has to be switched OFF to let a receive signal come in for DMR synchronization.
The only DMR amplifier I have seen so far and bought was on e-Bay, but it cost about $120 Can.

I am looking at 2 solutions to increase my DMR signal from Rawdon to Montreal.
1st is a small UHF Beam, pretty cheap as a solution, and the other is a
Mirage VHF / UHF Amp BD-35 ($ 209 U.S.) that is said to be D*Star ready
i would think it would also be fast enough for DMR, details found in the MFJ catalog
you may want to give MFJ A call, to make sure it switches fast enough for DMR
it puts out 35w on UHF
I hope this helps
