20 Most Recent Uniden UM380 Fixed Mount VHF Radio, White Questions & Answers


You might want to piggyback the radio hot wire onto the stereo fuse as that one might have a filter. You could also add a choke inline on the power wire or install a noise filter.

Garmins have USB or Data connectors - or both
obviously radio needs one of those inputs.
radio must be setable for Garmin format. If NMEA only verify Garmin is set to output NMEA - some do not have that option.

It all depends on the location. Being VHF and not using a repeater or external antenna, the range is likely less than 10 miles. Using a repeater you might get 50 miles or more. If you are thinking long range communications, you really need an HF transceiver. VHF is essentially for local communications.

If you get clear audio when close to the receiver, it would appear to be a problem in either the antenna or the receiver. Try a different antenna or relocate the antenna. If you adjusted the VSWR low it doesn't mean the power is radiating correctly. Verticals should be on roof, with roof as ground plane. Mounting on mirrors is ok, but doesn't work as well. Also, if you have sheet metal near the antenna, it acts as a ground reflector and can distort or block the waveform. You might also try it with a different receiver, in case yours has a faulty pre-amp stage. It could also be a power amplifier problem in the transmitter, where it shows 5 watts but isn't putting out that amount. You can check it with an RF watt meter.
