Motorola MSF5000 UHF
Model C74CLB-710AT
Serial 474CPL0065

Can anyone give me some basics on this repeater? I'm trying to find out specs and ability to configure PL, etc.....

Any information or links to where I can get more information would be greatly appreciated.

Thanks in advance.

110w UHF prom programmed MSF5000.

have to program with the R1801 DAC (pain in the butt)

can't change anything w/o a new prom (call/pl/freq, etc)

can't tell the bandsplit tho w/o either having access to the station or reading the prom

Would 173.3 or 178.3 be valid PLs?

Are there still techs who can program these? I wanted to get it looked at and given the 'once over'.

Its in place in a Downtown Atlanta location.

Andy Brinkley, a BatBoard member, does the proms, Brinkley Electronics.

Most of the MSF5' were 435 to 475mHz, and the 74 tells me that it is a 110 watt continious duty. It may have circulators and or duplex which brings the power to about 75 watts.

Only disadvantage, is the PROM, but it can have several channels in the PROM, and you can select the one you need.

Thanks for your help. We know the freqs, 450 out 455 in.

The TX and RX freqs. and PL or DPL codes for each channel are in the prom, along with the repeater settings. Repeater settings are: Squelch setting for valid repeater key up, delay and dropout, time out timmer and some others.

Have Andy smoke your prom with a new channel and strap the channel select for that added channel. Re align the MSF5 and you are on the air.
