Communications Specialists 6 Position Dip Switch Programming

This chart is for all the newer Com-Spec products, including the TS-64 series, that use the stock or standard programming only ‑ some custom units were produced that had the tones programmed in a special sequence.
You will occasionally find a field mod where a six‑position or seven‑position switch has been used to replace the five‑position switch on a TS‑32 series product. The most common situation has the extra switch used to select tone decode mode or carrier mode. Please refer to the five‑position switch web page.
And you may find a seven or eight position switch used on a six-position TS‑64 product with the extra switch(es) used to implement individual enable/disable control over the decoder or the encoder or both.

If you have a collection of radios made by a variety of manufacturers on your system then you should avoid tones below 67.0 Hz and above 203.5 Hz as many older radios don't have them (or if they do, they can have different combinations of them).

0 = zero = switch on or shorted = a logic low       1 = one = switch off or open = a logic high

Notes:
1) The tones that do not have an entry in the "Tone Code" column (i.e. are blank) are not EIA standard tones.
2) Digital PL / Digital Coded Squelch uses a clock rate of 134.4 Hz, so it's a good idea to not use 131.8 Hz / 3B or 136.5 Hz / 4A on any mixed-mode channel.
3) ØZ: Thats a zero, then the letter "Z". It's an unfortunate confusing truncation of "10Z" into a two digit field.
4) Tones above 203.5 are not recommended in older radios as most PL filters have their "knee" at 200 Hz.
