INTRODUCTION The Mentor Model M15 receives and transmits on up to six discrete channels in the vhf aviation band between 118 and 137 MHz (25 KHz channel spacing). It operates from a 14 v dc supply, and is intended for both vehicular and airborne application as well, and can also be used as a base station.
INSTALLATION The M15-25 can either simply rest on a shelf or desk, or it may be mounted in a 19 inch relay rack. When rack mounted, rear support is not required. This unit does not contain a cooling fan, and does not normally need one.
(fully CCW, without turning radio off). It is not necessary to turn off the M15 if the M15-25 is turned off—the power to the M15 is removed when the front panel rocker switch is turned off (green LED goes off). If the M15 has more than one frequency, select the desired channel.
It’s level is factory adjusted to 0 dBm (0.77 v rms) but may be adjusted internally for any level from -7 to +10 dBm by trimmer potentiometer R205 on the printed circuit board inside the M15-25. Both the 4 ohm and the 500/600 ohm receiver audio outputs are unaffected by the volume control on the M15, the latter affecting only the speaker on the front panel of the M15-25.
With each new M15, Mentor Radio, LLC. include instructions on how to complete form 406 online at the FCC Internet web site (Dwg. 1100958). If the M15-25 is to be used on a channel in the frequency range 128 to 132 Mhz (the “enroute” channels), the license application is handled differently.
