The mod listed for super-expanded
frequency coverage (RX and TX) of the Kenwood TM-G707 is incorrect!
I have read multiple reports (also on QRZ) that for the expanded
frequency coverage, it is necessary to remove the SMT resistor
marked "1", NOT the one marked "0".
This is INCORRECT, at least in my radio, which was purchased NEW on
4-3-01. Removal of resistor "1" changed my radio from the "American"
version to the "European" version (described in more detail in the
instruction manual), which actually DECREASED the frequency coverage
to LESS than it was before modification (again, both RX and TX were
Also, the ability to program the microphone buttons yourself was
totally disabled. I called Kenwood and they couldn't help me, since
the mod I'd performed was not endorsed by Kenwood.
I put resistor "1" back in place, and removed resistor "0". All
the disabled functions were restored, and the frequency modification
(both RX and TX) was completed. This correction may not be the case
with all of the TM-G707's out there, so my advice is to remove only
one side of the resistor you choose to try. Using your soldering
iron, heat it up and just bend it up far enough to break the
connection, without removing it completely from the PCB.
If you notice undesireable changes in your radio, reconnect it
and try the other one. There are only 2 of these resistors in my
radio, so it should be a simple process of elimination. Good Luck!
