What to do if my M-tech MT-700 Marine Radio reports weak transmit signals?
Weak transmit signals, even on HI power, can stem from antenna issues. Have a technician test the transmitter output power and antenna VSWR. Also, inspect the antenna cable for nicks, as wet coaxial cable absorbs transmitter power.
Why is there no sound from my M-tech MT-700 speaker?
If there's no sound from the speaker, several factors could be at play. First, check that the squelch control isn't set too high by setting the SQ control full CCW, and that the volume isn't too low by setting the PWR/VOL CW. Also, ensure the mic button isn't stuck, blocking the channel; try selecting a different channel and look for the TX annunciator in the display. Finally, a faulty external speaker or cable could be the culprit; unplug the external speaker cable to test.
