Just a quick comment - I recently bought a pallet of 15xMHz range MSR2000 VHF continuous duty stations. I sold five of them to a few of the local radio/repeater clubs to replace their aging Micors, converted mobiles, and other garbage not worthy of sites they are fortunate to have.
The pairs were two 146.4 rx / 147.4 tx, a few on 146.8xx rx / 146.2xx rx, and one down in the 145.2xx range. All have tuned down just fine, both rx and tx, with no mods. Yes, the tuning cap on the 2602 PA was almost maxed out for optimum power, but all of the PAs were making in excess of 120w (some 140w+ when the power control was set to max.)into the COM120 and Bird 43. The receivers all tuned to below 0.30uv for 12db sinad. The 145.xx receiver down in the 144 rx range was close, as most of the slugs were close to full-in, but never the less, they are all on the air and working great. All are running at 80-100w with no issues. One of them, set to 100w, has been on the air non-stop during the recent shuttle mission (via IRLP node audio). The trick is to add some nice 4" fans on or above/below the PA to keep them cool. The PA on the station mentioned above never got more than luke warm, even after on the air for hours. The audio quality on the MSRs is fabulous. We used Arcom RC210s on a number of them, which interfaced really nice, other than the few quirks, like trying to get link courtesy tones to work properly, or the annoying design flaw with the audio crosspoint switch loading down when an ID and receiver are active at the same time. BTW, if anyone is looking for a nice clean cont. duty MSR2000 VHF repeater, plug-n-play ready to place on the air, I have a few left. All clean, complete, tested and working 100%. Have a few int. duty VHFs also available (but no one seems to want them when I have the cont. duty stations!). I've been selling them complete, turn- key, crystaled and tuned to requested pairs, and wired for desired controller of choice, for $500. Will also install and adjust controller if supplied. Where can you get a repeater better than an MSR2000 for that? Converted mobiles are going for as much. Also, I'm looking for a few of the MSR duplex PL cards, and a set of reeds for 131.8Hz. Anyone? Trade/cash?
