: Replacing the standard memory can expand the radio from its original 48 channels to 480 channels 10-Meter Band
The most common reason ham operators seek out M700 radios is to gain access to amateur frequency bands. For the variant—which often comes with German FTZ certification restricting transmit to marine bands only—a straightforward hardware modification exists. icom m700 mods
The original unit only has 48 memory channels. Advanced users often replace the internal SRAM to increase this significantly (up to 480 channels).
For the M700TY variant, power adjustment is accomplished via a potentiometer on the main board. is the critical component—a variable resistor that controls output power. Turning clockwise increases power output while counterclockwise decreases it. The factory default is 150 watts. By rotating R244 clockwise approximately 15–20 degrees, maximum output can be increased to around 210 watts, with current draw increasing from approximately 22A to 28A.

If you are opening up your IC-M700 for modifications, take time to perform these preventive maintenance steps:
Swapping the factory electrolytic capacitor with a lower value (e.g., changing a 10µF to a 4.7µF) quickens the AGC release time. Advanced users often replace the internal SRAM to
and general power modifications are documented to improve operational flexibility. "Interesting Report": Restoration Hazards
Look for a row of small switching diodes (often labeled D1, D2, D3, etc.) arranged in a matrix pattern near the main microprocessor. The Modification:
For digital modes like FT8 or SSTV, you can build a small interface box that plugs into the mic socket to handle soundcard input/output and PTT. 🛠️ Specialized IC-M700PRO Steps
