Are there any web sites in Canada where I can purchase a marine VHF radio antenae? Approx. how much can I expect to spend? Are there different styles that best fit certain needs? I am looking to install in my river boat but also use in my Pickup truck during hunting season. Thanks in advance Dave

Well, it powers on, that's good. The most obvious is: are you near or do you have another marine radio to talk to it? Other than that, the trouble shooting list is LONG. Frequency, tones, antennas, contacts, on and on. I suggest taking it to a shop, not just because we run one. A shop runs 80% of the tests in about 30 minutes. Ask first the minimum shop rate (usually a half hour) and decide how much you want to spend on repair. No guarantee it can be fixed.
Your radio with model number M33GMC09C2AA is a GM300 made for Central Asia, Eastern Europe and Turkey. It is VHF 25 watt with 12.5 channel spacing. It will do frequencies between 146-174 MHz. It should be able to be "read out" by a Motorola dealer. If it has been in a boat, it most likely is programmed with Marine frequencies. If you have another marine radio you may be able to determine the frequency by process of elimination.
The wiring kit for power is readily available for around $18 ea. If your boat has a marine VHF antenna onboard, you will be able to attach the antenna to this radio. It takes a mini-PL connector.
It is not typical but neither is there a problem with the radio.
Transmit Power output is loosely dependent on the:
1. Frequency or channel you are transmitting. Normally, Marine Band VHF are calibrated for max (25 in your radio) at Ch16 or 156.800Mhz;
2. If the SWR of the antenna is not a flat 1.0, power tends to go down;
3. After some time, the TX side of the radio needs to be re-calibrated;
4. Power Supply - some radios will push max output only when powered with 13.8 and tends to go down when used with 12 volts.
Hope this be of some help/idea. Post back should you need additional information.
Good luck and kind regards.
