Very interesting... I have a Motorola Micor 800MHz-75w continous duty PA, and a Motorola Nucleus paging PA (supposed) high power. I never really thought about what to use them for, just stacked them in the shack for a "future" project.
I was actually thinking about 900-ATV (FM of course)... I also have a small "Mitsi" brick that I managed to get going, good for about 20 watts before it saturates. What would be entailed in converting a 800MHz Maxtrac to narrow-band FM(I don't have the model number handy right now)... is it worth the effort? Will the Maxtrac even do 2.5 kHz? One of those things I just haven't had time to investigate.

Motorola (Micor, MSF, GTX, Purc & Darcom), EF Johnson (Avenger & 900 Mhz version of the 8615 Series), GE MVP, Repco (boards), Neutec (Ranger Series), MDS datapoint, RCA (yes, they made an 800 radio, which was pretty easy to convert) and a few others. > There are currently about 100 repeaters on 902/927 > pairings in the US, most of which are less than 3 > years old.. Actually, I'll bet there are a lot more 900 machines around, just not posted. Some 900Mhz repeater people don't post repeater locations to the public forums because of problematic "ah" hams known to frequent the more popular web repeater/radio groups. Some locations are agile with our wonderful utility companies using analog and spread spectrum meter reading devices. We have to move them around to find a clean receiver slot. > there is a significant effort to modify and build, > and plenty of parts available. It is definitely an > interesting band. Early 900Mhz repeaters were on the air in the late 80's. We found the mobiles picket fence a lot more than 445 operation.

Good information... > There are only a few GE 900 commercial products > that adapt well... The GE MVP 800 plays pretty well on 900 with reduced power. Many of the 90 vintage sf bay area repeaters were made with converted mvp radios. It was actually pretty cheap to get on 900 with converted radios. > YMMV.. > Doug > KB8GVQ > Cheers Doug 73's skipp www.radiowrench.com/sonic Yahoo! Groups Links Yahoo!
