Need schematic for a uniden es um525.


Need more information. Which channels don't work? Not all channels are authorized. Typically, the radio will not fail in such a way to allow some channels to work but not others.

Electrical for MC795 Marine Radio


Unfortunately, Uniden won't part with their schematics cheaply.
As a matter of fact, for about the same money you can buy a new VHF with DSC capability. Welcome to the world of disposable electronics. In case you or anyone else require the owners manual for the MC 795, I've included it at the link below.
Hope this was of same help.

VHF transmit power


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.
