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 Fm: Chuck Scott N8DNX 76556,3335 You can modify the 2 Meter section for 141-154 MHZ by adding D27 (not installed in USA version). Cat Software Yaesu Ft 736R Mod Manual For The I will try to use PDF file later, or some other format). I use IrfanView (version 3.17) for printing my PCB-layout scaled x 1.05 gives me the correct size.

Unfortunately I had to use a bitmap-file for the layout, you have to scale this to a PCB size of 6942.5 mm. I hope I can present a second PCB within a few weeks that can fit in a 9 pin sub-d connector, unfortunately this means soldering some SMD. I made a modification to the original circuit because the second set of ports in the MAX232 are better for making a nice PCB.
