RE: [Repeater-Builder] Poor Repeater RX
Heh... Yes, it is interesting to have lived long enough to have seen changes, but it is also good to go along with those changes instead of staying firmly mired in the past.

Re: [Repeater-Builder] Motorola APCOR
Al The APCOR unit came in a number of flavors. Could be MT-500 or MX-3XX or some other HT as the transmitter and receiver. IIRC there is a 10 Watt PA. The duplexer is usable. The unit should be 10 frequencies and 10 PL tones. Probably the PL tones are selectable separate from the frequency. The unit was capable of both voice and data transmissions. To get more specific one would have to have the model number or the type of HTs used to build it.

Re: [Repeater-Builder] Motorola APCOR
Al, I picked up a 12 watt APCOR unit a year ago, but have not found the time or patience to repair it, let alone try to modify it. The Coronary Observation Radios act as vehicular repeaters, and operate on the UHF Med channels in reverse- that is receive low, transmit high. They are based upon the MX300 modules, and use a separate channel element for each frequency. The service manual for the 1 watt models P24ESN3150A and P24ESN3151A is 6881021C05, which costs just $ 3.06- an incredible price. The service manual for the 12 watt model P44ESN3191A is 6881021C10, which costs $ 35.37. One of the reasons the APCOR units are plentiful on the surplus market is because the MX300 system is plagued with connector problems, sort of the Edsel of radio designs. The unit I have was removed from service only a few months before I bought it. What's really scary is that it was junk, but was being carried on an ambulance in Huntington Beach, CA! I have read a few articles about converting the APCOR into a Ham repeater, but none of them spent a lot of print space to extol its virtues. 73, Eric Lemmon WB6FLY Al Wolfe wrote: Hi, all, One of the few Dayton acquisitions this year was a Motorola APCOR unit.

Re: [Repeater-Builder] Low Power VHF (Ham) Radio
Thanks RSG, Your info will be of help, guess I will not go for the Rangr. Using 2 radios will increase power usage, and I need to keep this low, for portable use. As for freq. change, this of course would need the duplexer to be retuned for the freq. required, not that I believe it would be changed much. Just wanted something (radio) that could be changed if the portable repeater needed it. Maybe a close-by repeater had it's RX close to the portable TX freq. The main issue, is that the repeater TX must be low power, max 10 watts, most likely running around this value. Hope this tidies up my previous message.

Re: [Repeater-Builder] Re: Motorola APCOR
Coy, I've never seen an MX500, but I remember using the MX300R for an Air Force project back in the mid-80's. This was a ruggedized model that was encased in a black rubber jacket. Although somewhat reliable, they were pretty expensive- about $3,800 per copy with DVP encryption. The problems I referred to in the APCOR were similar to those seen in the 300-series handheld radios of the same vintage, where each of the functional elements in the radio was in a plug-in module. My buddies in the radio business said that every 300-series radio built had a problem with contact corrosion of looseness at least once in its lifetime- which was remarkably short. 73, Eric Lemmon WB6FLY Coy Hilton wrote: Eric, Wasn't the MX500 at one time, Motorola's Cadillac HT? Did they have the same connector problems? We had only one in our entire Fire dept. It seemed to have few but weird problems. That goes back 25 years. 73 AC0Y Yahoo!

[Repeater-Builder] SSB Remote Base
I was looking at using a MFJ-9406 6 Meter SSB radio for a 6 meter remote base at my reapeater site. Any Ideas on how to get a COS/COR signal out. I thought about using a CAT Tech SQ-1000 Squelch board but didn't know how it would handle the pulsing nature of SSB. Has anyone tried this or something similar ?? Eric Kc5Fog Yahoo!
