- I found this on Compuserve. I tried it on my FT736, and it works! I wonder
- what the other diodes do? Does anyone have a service manual for the FT736?

- You can modify the 2 Meter section for 141-154 MHZ by adding D27
- (not installed in USA version). This is normally soldered to the
- board but you can easily install it by simply shoving the leads into
- the connector. The 2 Meter section is the middle board looking into
- the radio from the top. The connector (J09) is the large one on the
- right side of the board, half way back. You want the cathode (striped
- end) of a small signal diode in pin 7 and the anode in pin 4. Pin 1
- is toward the front of the radio.
- To receive over a slightly wider range, place the SAT switch in RX mode,
- press ENT[D] then enter a desired frequency and press ENT[D] again. You can
- enter any frequency from 100 to 200 MHz this way. Unfortunately, the
- synthesizer does not actually cover that range. As far as I can tell the
- bottom end is about 138.5 (not quite the 136.5 needed for the weather sats).
- The top end is about 155.6. You can't perform this stunt with the normal
- (non-satellite) VFO's. Also, once a frequency is entered in this way, it is
- possible to tune toward the normal range but tuning away will place you back
- in the 141-154 range. Using the same method yields aprox 220.0-229.5 &
- 423.0-454. You may store these frequencies in the SAT Memories.
