A hum doesn't come from frayed D.C. power wires, but it should be fixed. If it shorts, it will blow the fuse or even worse blow the power supply. The first and easiest thing to try is swapping out the mic. The next easiest thing to try is swapping out the power supply if possible. A spare mic is ...

you need two frequencies for a repeater but if the license is still good you should be able to get it altered easily.
While this is basically true, the FCC may not allow it depending on where you are(major metropolitan area vs rural). Rural has a decent chance. Where ever you are, the frequency ...

If the power line filter idea doesn't work, you may have to attack the issue at the source. Is the noise a whine or a clicking sound? Clicking indicates ignition, and a whine indicates the alternator.

Sorry for the delay in responding. I am currently at the beach(pool,hot tub,alcohol), and don't get online as much. That and because I'm a newer member, my responses are moderated.

What part of the country are you in? It would be easier to communicate if we were close. This may end up with a phone ...

I have been out of the Moto business for about 4 years, so my "help" may not help. I can tell you how to find out, but only if you have the RSS for the GMs, and the CPS for the CDMs. And if my memory serves me , the plugs on each radio is physically the same. In each of the programming softwares ...

A field strength meter will prove my point. Or a radio with an S meter and a mag mount antenna. The second would be a better test as the true test of a rig is how well it "hears".

Regarding the govt repeater- The govt can pretty much do whatever it wants, just like the police. But if they were to follow their own rules, it would ID. It may ID, you just might not be able to hear it because of PL GMRS rigs should also ID. Not to repeat my self(no pun) this is done in the ...

Now we have a much better picture of what is going on. Certainly the UHF on the tower has some effect on you rig. But my guess is that your antennae are giving you the most trouble. Or more so the cable. And let me guess, you had to extend at least one of them.

The vertical separation you have is ...

The higher the freq, the better they work. And when tuning, you are not tuning a match between the radio and antenna, you are tuning between the radio and the box on the inside of the glass. That box is a resistance matching device. With no physical connection to the mast, there can be no actual ...

Don't be so quick to move, especially if it will cost you. Not to sound picky, but your use of the word "tower" may have confused the issue. Is it a tower, or a single cell site? A single site 40 yards away shouldn't cause too many problems. It's at 3 watts at 800mhz or higher.

Tell me about your ...

There are antennae that are low profile in design, that resemble(not oblong, but circular) for most bands. I believe they are referred to as "radome" style. Manufacturers include Antennex and (maybe) Maxrad.

Not wanting to sound like a wannabe cop or anything(especially with my first post) but before you go on the air, make sure you get legal. Which includes a controller that IDs properly. You may think that, out somewhere on some mountaintop, no one will hear you. Well, radio doesn't always work that ...
