SQL (COR) Input
The SQL (COR) input is connected through a optocoupler to the CTS control
line of the serial serial port (the same port used by the PTT / CW). The input
of this optocoupler is an LED, which may be biased with a 2kΩ resistor with
positive or negative logic (defined by SJ6 and SJ13). With SJ8 (see also Pull-Up
resistor for the CW / FSK output) you can set the supply source (internal or
external) in the case of negative logic. This supply voltage is also about 5.1V.
