See ICOM IC-M11 for freq. chart.Date: 19-03-2002 User comment From: Ken WA4BJNSubject: M-58 and M-59 require prog.softwareIcom m-58 and m-59 do not have switches ect you must have programing software to add additional channels, you canprogram the radio to cover a freq. spread of about 130 to 170 MHz in addition to keeping the factory programed marinechannels, dont open these models up looking for jumpers or switches, you need the software!!!This modification is read 195 times.top of page19-07-1998(IC-M700) ICOM M-700 Marine TransceiverDespite that the literature says, no lock-out is employed. For ham frequencies on 40, 80 or 160 meters, set the mode switch tothe hard left position of "A3," to enable the lower sideband filter (all marine HF uses upper sideband).This modification is read 616 times.top of page05-11-2001(IC-M710) Cloning program for IC-M710Cloning program for IC-M710 MF/HF Transceiver.This modification is read 538 times.top of page19-07-1998(IC-MU2) IC-MU2 Ext Band mods1. Remove battery.2. Remove 4 screws securing battery. Slide from front panel.3. Remove small black screw below PTT switch.4. Carefully separate the front speaker from the body by pulling front and rear down toward battery. Flip it over.5. Next remove steel chassis assembly by gently prying up the sides, lift up, fold it down.6. Solder in new diode next to Q131 and Diode D113. Looking at Diode Matrix with top of radio to the top, add diode to theempty pad to the left of diode D119. There are 3 points of connection on the diode pad. Two on the left and one centeredvertically on the right. The diode should be installed between the lower left and the right centered connection. (Arrow ondiode points to right centered connection.)7. Reset CPU by following instruction manual page 23.
