The most sought-after mod for the TKM-707 is the MARS/CAP (Military Auxiliary Radio System) expansion. By default, the TKM-707 is locked to marine frequencies and will not transmit on amateur bands.
You can fine-tune the beep and alarm tone levels using internal potentiometers (VR7 for beep, VR6 for alarm) if they are too intrusive during operation. 3. Essential Maintenance "Mods" for Reliability
Electrolytic capacitors in the power supply and audio stages are prone to leaking. A proactive recap kit installation can prevent board damage.
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
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
Unlock the transmitter to cover the full 0.5 MHz to 30 MHz range of its receiver.
Below is a guide to the most common modifications, maintenance hacks, and performance upgrades for the TKM-707. 1. MARS/CAP Modification (Wideband Transmit)
Because these units are decades old, certain "maintenance mods" are required to keep them operational.

I would just like to know what are the welding symbols used in this drawing or in the plan and also what are the joints configuration used.
This is a die-cast aluminum gate. There are no welding symbols.
