MASTR III - General Opinion?

Post by MOTechGuy » Sun Jul 01, 2018 2:39 pm

I've found what I think is a deal on a range 1 VHF MASTR III. It is an analog only one, model SXHMCX. I do plan on interfacing an MMDVM to it.

My question, what's everyone else's opinion on it for ham use? Are they decent repeaters?

Should I pass it and buy a Quantar instead?

For the price and your intended use with the MMDVM - I'd say go for it. They seem to be solid performers in terms of reliability - and the RF modules are easy to find (easier than Quantar parts at this point) and seemingly dirt cheap. Repeater Builder also has an easy tutorial to change VHF R2 boards to R1 using some cap nuts and silver solder to lengthen the tuning stubs.

In all, I am looking at doing exactly what you're doing. I have a VHF R2 Quantar complete except for a matching VHF R2 PA module - and I can't find one for less than $900 - at which point I can build an entire MMDVM repeater and save the Quantar for later.

Thanks for the info. I went ahead on the deal, we'll see how it works with an MMDVM. Finally found the MASTR III R17 DOS programming software so now I can program it.

Additionally, I have a lead on a VHF R2 MASTR III, but not really interested in all the modification that's required.
