In a mobile, that would depend on what's in the drawer unit. The RF preamp, PL encoder, and PL decoder board draw power from the 9.6 volt line. Other options may as well. If memory serves, and I wouldn't recommend you take this to the bank, Motorola specified a maximum current draw of 1.2 amps f

Yep - then it's a 2553 (I think it's a 255x) just can't remember the last number. They are more difficult to find. Mine is a copy - and there was only room to print the 255 and the X couldn't fit on the key. If someone doesn't take care of you here - I can get copies. Bill Hudson -

Just because I gamble a little - I'm going to bet that the older Motorola cabinet is a CH751. This is a one sided key unlike a 2135. The Micor cabinets became a 2553. Cabinet Keys more prominent in the high power stations. I'll go along with the BF10a for the Prog Line - that's for sur

RE: [Repeater-Builder] Re: Can the 4th harmonic of 1250 AM keep UHF repeaters locked up?

Hi Tony, Are you using a duplexer on this repeater? A lot of cavity filters act as a short circuit to DC and low frequencies, so additional filtering is unlikely to help. I can only think of one type of cavity that has a DC path between from input to output (via an internal inductor) and not to

RE: [Repeater-Builder] Re: Can the 4th harmonic of 1250 AM keep UHF repeaters locked up?

I would have thought good grounding practices on the feeder and equipment at the base of the tower would have pretty well bypassed any 1.25MHz stuff. Ferrite 'beads' will reduce common mode pickup on coaxial cables without any effect at all on the signal inside the coax. Don't expect too much a

Re: [Repeater-Builder] Re: Can the 4th harmonic of 1250 AM keep UHF repeaters locked up?

How about 1.25 MHz RF coming down the outer jacket of the UHF antenna and into the ground of the system? You have about 200 ft or so of coax? Try a mag mount antenna temporarily. Not really sure how you'd cure that though. Not sure if snap on RF beads would work on coax with a signal going in the

Re: [Repeater-Builder] Re: Can the 4th harmonic of 1250 AM keep UHF repeaters locked up?

I was able to match up the audio coming through the repeater and the local AM station. My latest theory is that their signal is so strong that its blowing into the receiver's front end and multiplying/mixing there (past the bandpass filters and all). They are heterodyne receivers after all. I'
