100HZ Tone Generator info for repeater access?

Post by Jeffrey L. Baum » Mon, 06 May 1996 04:00:00

Anyone seen any articles and/or circuits for a 100hz tone
generator I can use with some older 2 meter gear to access
some local repeaters?

I'd go down to the radio store and get a Communications Specialists
SS-32 encode-only CTCSS encoder.  The frequencies are dip-switch
selectable.

I have built my own CTCSS encoders in the past, but the 1%
resistors are usually hard to track down -- stability of CTCSS
tones if VERY important because they should be accurate and
stable to a tenth of a Hertz, 100.0 Hz in your case.
