Try replacing the microphone, some radios will not even show power with a faulty microphone. also, check that you have power to the hot wire and the ground is grounded by use of a multi-meter.

When you mention producing power, do you mean it won't turn on or it won't transmit?

If it won't turn on, it can be anything in the power path includding the mic. But if it turns on but doesnt transmit the proper amount of power, then it can be the transmiter amp. Most often on models like these, there is a single high powered transistor near the antena output with a heat sync. It is usually a very cheap fix if you can identify the componants.

My garmin 545s does not turn on


My Garmin 545s would not power up. I took the unit to West Marine, where they had the correct cable to hook it up and test it. The unit immediately powered up and I purchased a $22 cable and installed it. Easiest test and fix I could come up with. Really cheap fix.

I have my cb grounded and a wire ran to the postive side of my battery terminal and the antenna wire ran and my cbs channels wont come up we thought it was jus my cb so we hooked another up and it did the...


Hello,

Here is the deal, even with out antennas hooked up, you should get at least your channels on your cb showing, no of course you would have all noise and distortion with out antennas hooked up. And sense you hooked another cb up with same results it tells me, number one, it is not most likely your cb. If your channels are not even lighting up, then this tells me it is not getting power. I know you said that the cb is grounded, and there is a wire ran to the positive post of the battery. What I would do first of all make sure proper wire on cb is grounded and not reversed accidentally, but what i believe is your not getting power to the unit, if it was properly installed, there should be a inline fuse from the cb radio to the positive post the wire is connected to on the battery. I believe there is a inline fuse that is blow, or not a good connection on the post of the battery. To test this theory, take a long piece of same size wire gauge, and run direct from positive on battery to positive post on battery, of course making sure that the proper wire off the cb is grounded (must be grounded to something metal, might find different spot to ground the radio if not for sure on metal) If you get lights going on then on radio, then your problem, was not a good connection or inline fuse on positive wire that maybe you didn't see was blown. Let me know Mike

Hello bonnett35, It does not matter. Your marine antenna doesn't have a 'earth ground',only the shield of the coax might make contact with GND if the connections are not insulated (tapped,coated). The FCC has enough problems with public broadcast & WIFI. Private unlicense marine use maybe easy money for them in the form of a fine.

Some reception produces a crackle noise and stronger ones not. This is not a squelch issue. It is a different noise, like a short in the antenna or something.


Check the antenna PL259 connector. It sounds like the ground (shield of the coax) is not attached properly. I would recommend replacing it with a solder type connector and solder the shield to the outer ring of the connector and the center conductor to the tip of the connector. If the problem still exists, I would recommend trying a different antenna.

Non grnd steel antena


I assume your coax is not hooked up properly or you have some kink of a short in your antenna connection ( thats if your cb is working properly ) Radio Shacks Information that suggested that the 102" whip is the perfect antenna is their opion only as I prefer to recommend a full wave antenna system to my customers, but I do assure you, the 102" whip does work well if it's properly installed. I have found the main problem in the 102" whip installation is when the center hole is cut to install the antenna, it's not cut big enough, which grounds the antenna. It's not suppose to be grounded in any fashion to the automible chassis. The ground of this antenna comes from the 3 screws mounted around the outside of the antenna mount. Check that for sure. If you can't correct the problem. write me back at this web sight of direct at [email protected]. Good Luck

AMP turns ON then turns off


The power antenna wire only supplies 12vdc when the radio is on. When CD or other sources are selected, the power antenna wire goes to 0vdc. The remote turn-on wire provides 12vdc whenever the head-unit is on. If your amps are powered on only when the radio is turned on, I would bet that you have the power antenna wire connected and not the remote turnon wire.
