Programmable crystal controlled 47 tone CTCSS encoder kit
1.
Programmable crystal
controlled CTCSS tone encoder kit
2.
It can encode the 47
CTCSS tones listed below and generates a sign wave.
3.
Output level is fairly
flat from 67 to 118Hz at approx. 3V p-p
and
then falls gradually to approx. 1V p-p at 254Hz, most
radio’s
require less CTCSS input level at higher frequencies
so
this is ideal.(10K VR adjust output level range)
4. There is an encode enable input that connects to the radio's
PTT line (active low). You can tie the encode enable input (PTT) to ground
for continuous encode.
5. Fit the 6 supplied Switch in the following combinations to select the
desired tone frequency.A Switch ON is fitted to represent a logic zero (0).
6. 47 CTCSS tones Frequency Accuracy: Guarantee ±0.01%.
7.
It's powered by 7 to 15V
DC and draws less them 10 mA.
8. The product needs to be assembled and soldered by yourself.
9.
PCB size is 40 x 44mm.
