Is anyone running an older modem with their 6000 series? I have an AEA PK232MBX modem that will soon have the latest firmware and DSP upgrades installed and, while I have a cable to connect it to my FT-897, I'd really like to be able to connect it to my 6500. The PK232MBX has a 5 wire connector on the rear to be connected to the radio and the pin outs are 1-Receive Audio, 2- Microphone Audio, 3- Squelch Input, 4- Ground, and, 5-PTT. 15 pin jack on the back of the radio, I can line up most of those and the 8 pin mic jack on the front is close but doesn't appear to have the same signals. So, is there anyone running these two devices together?
