The indicated mod is INCORRECT. It may be for earlier TS-850 or wrong from the start. I expect the former may be correct. The indicated mod says move diode D11 to the D9 position, then reset the radio processor. This results in many bad things happening, including antenna tuner malfunctions. The correct mod, verified from several sources and actually performed on my TS-850S (c. Sept 1994) is to ONLY cut the lead to the D11 diode, i.e. open that circuit. This allows xmit over the MARS bands (tested in the 7200, 5120, and 4035 kHz ranges) and indeed probably over the entire 500 kHz - 30 MHz MF-HF bands. Please remove or augment this mod to indicate that it may not work on all radios, with suggestion to get the mod from Kenwood direct (a MARS or CAP license must be FAXed to them). Thanks for the good work and all the other info you provide. 73s de KC7JEI - AAR0MO, Randy Lloyd
