Question about Garmin VHF-725 2-Way Radio
I have a VHF marine radio with 25W of transmit power. When I connect an SWR meter and key the mic the meter reads 16 to 18W. Is this typical or does it indicate a problem with the radio? Thanks.
Thank you for the info...very helpful! I guess the real test is if I can be heard by my fishing buddies. Thanks again.

Hi, 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.
