TS-64DS
DIP Switch Programmable CTCSS Encoder-Decoder
Same circuit as the TS-64,
but with an on-board DIP switch to allow tone selection without soldering
jumpers.
All 64 tones are accessible via
the 6 position mini DIP switch. The TS-64DS measures 1.25" x 2.0"
x .30".
TSU-64DS
Universal Plug-on Type CTCSS Encoder-Decoder
Same circuit as the TS-64. Chassis pins
extend from the bottom of the board. This facilitates direct plug-on to
special application boards that are designed to be plugged into many popular
radios.
Also features an on-board DIP switch to allow tone selection without
soldering jumpers. Size: 1.25" x 2.0" x .30".
