Mastr III is a good choice. MTR-2000 is a good choice also, but repairs if ever needed can be VERY expensive. Power supplys are out of sight. Are you totally sour on Kenwoods. I would look into the TKR-7400 series from Kenwood systems. Really good specs for the price. Back to the 720. What is the power output set too, or how much drive does the TPL take for 100watts out? I have had to re-solder the RF pa transistor in one or two in the past. They don't like running wide open all the time. TKR-750 is a good repeater also. 73 de N5NPO

If had an emergency manager willing to pay for a repeater I would replace it with a Motorola MTR2000 with the front end pre selector and necessary connection to connect to an external controller. Hard to get much better.

Our local RACES group has a Kenwood TKR-720 driving a TPL PA that they were ill-advised to purchase some years ago. It is maintained by the county radio shop for various reasons and has been a nightmare. Once again the final in the Kenwood has done a meltdown. That said, the local EMA manager, also a new ham, wishes to replace it if he can squeeze the funds out somewhere. My recommendation, obviously the most expensive, was a Master III and new Arcom controller simply because the county already maintains three VHF M3's and a 5-site, 8-channel trunked system using 800 M3's. Parts and support are good. I would really appreciate input, both regarding setting up a Master III, or other viable repeater. We need, minimally, 100% duty-cycle at approximately 100 watts, good parts and support available, and reliability. Is there a decent source for M3's with P25 becoming more desirable, etc.. I don't want a, "mine is better than yours," war so off-reflector replies are also welcome. TIA... Len Revelle N9IJ [email protected] <mailto:n9ij%40comcast.net>
