- TH75E frequency coverage extension
- ==================================
-
- On looking at the circuit diagram around the CPU I noticed a link marked W1.
- I wondered if this link did anything, so I took the rig apart as instructed
- in the manual for fitting the TSU6 board, as I have already done.
-
- Looking at the circuit board on the keyboard section lid, I saw W1, an
- insulated wire link near the CPU and the diodes D3, D4 (D2 is missing from my
- circuit).
-
- I removed the wire link and switched the set on.
-
- It now has extended Rx coverage:
- 136-169 MHz
- 390-471 MHz
