Tone board for Kenwood TR-7600
Today I picked up a Kenwood TR-7600 2 M FM transceiver at a hamfest. Works good, except it does not have a tone board for repeater access.
Does anyone know what tone board I need for this radio, and where can i get one?
Thanks in advance.

Thanks W9GB. Just got my board in today. Installed it and so far it works, although for some reason there's a repeater 20 miles from me, that on 10 w. all you hear is a buzz when I key up, but when I drop it to 1 watt I'm clear as a bell....but the repeater 10 miles from me is fine on 1 or 10 watts. I tried adjusting the little pot on the radio but to no aval. Anyone know why this is?
Considering where you're located / stationed, I'd try to find the electronics shop where they might have a Service Monitor to set the CTCSS Subaudible Tone to +/- 750 Hz Deviation Level. That tone might be over Deviated causing what appears to be a BUZZ on your Audio transmitted signal. Once that level is set then your transmit audio Deviation should be set at +/- 5 KHz with 1 VAC @ 1 KHz audio signal fed into the mic input connector for Analog FM Deviation. Using this method of setting the TX levels will insure that your TR-7600 is not over deviated. Perhaps the repeater 20 miles away does not have a Subaudible Decoder Filter which strips the transmitted CTCSS / PL Encode Tone Frequency out of the repeated audio. I hope you can understand what I'm trying to convey to you.
