Like many Kenwood rigs of its era, frequency expansion can sometimes be achieved by modifying specific internal components. While specific diode/resistor locations for the are less documented than for the , community resources like
: Disconnect the DC power cable and antenna inputs from the transceiver.
He adjusted the IF shift. The modded filters narrowed, slicing through QRM like a scalpel. There. A ghostly carrier.
The community has created a functional, if not "elegant," way to connect the radio to a PC. kenwood tkm707 mods
: Remove the top and bottom covers of the transceiver. Locate the control unit board (usually designated as the digital or logic board).
: While the factory ceramic filters limit overall fidelity, subtle adjustment of the audio compression circuit can alleviate the "tinny" restriction typical of commercial marine mics. 3. Interfacing for Digital Modes (FT8, VARA, PACTOR)
Factory mic gain is low for dynamic mics: Like many Kenwood rigs of its era, frequency
: Mount a quiet, low-profile 80mm or 120mm computer fan directly to the external rear heatsink fins.
As a high-power (50W VHF/35W UHF) radio, the G707 can get quite warm during extended transmissions or packet radio use. Many operators mount a small computer fan on the rear heatsink.
: Remove the top and bottom covers by unscrewing the retaining screws on the side panels. The modded filters narrowed, slicing through QRM like
Static answered.
The S-meter on the TK-M707 can sometimes be less accurate. Calibration mods can improve the precision of signal strength readings.
Position the radio upside down with the antenna connector facing you. Locate the small, vertical printed circuit board (PCB) behind the display adapter.
