I researched the 5 pin DIN connector that is on the back of the THP 1.5KFx amp's Yaesu interface jack and have a part number. This will enable any K3 which has the pullup resistors for band data installed on the KIO3 through the ALC mod or factory cut in to output band data to the amp and have it follow band changes just like the K3 was a Yaesu transceiver.
The SwitchCraft part number is: 12GM5M (presumably series 12GM, 5 pin, male) The Mouser part number is: 502-12GM5M It is important to note that this is a male connector with 5 pins distributed around 240 degrees. The more common 5 pin DIN connectors have the 5 pins distributed around 180 degrees, these will NOT work. Wiring is straightforward from the DB15 connector to the 5 pin DIN. 4 signals plus ground. And ALC as a separate cable for those so inclined. www.zerobeat.net/mediawiki/index.php/K3_to_Tokyo_Hy-Power_HL_1.5KFX_amplifie r shows the wiring diagram; presumably a K3 with the pullup resistors installed internally does not need the external 5 volt source.
