This typically involves removing specific surface-mount diodes or 0-ohm resistors on the control board. Professionals often perform this during a full alignment or capacitor replacement service . 2. Audio & Modulation Upgrades
Many users report that adapting an Alinco microphone significantly improves modulation depth and clarity.
Because these units are decades old, certain "maintenance mods" are required to keep them operational.
While the TKM-707 has a "large efficient cooling system," it can still get very warm during long high-power transmissions.
For heavy amateur radio use (like FT8 or RTTY), adding a small 12V computer fan to the rear heatsink is a highly recommended non-invasive modification to prevent thermal throttling. 5. Technical Quick Reference Original Spec Modified Potential TX Frequency Marine Bands Only 1.6 MHz – 30.0 MHz Power Output Stable at 150W with cooling Memories 198 Channels Fully programmable via front panel Antenna Tuner Works with AT-300 Compatible with various LDG tuners via interface mods
