9. Controllers Accepts incoming logic and applies and outgoing logic
Logic = Audio, Voltage
Can be as simple as a switching transistor
The controllers of today come with timers, ider’s, and some form
Of remote control via DTMF.
This is true of most home-brew controllers also.
You wont find many features in the aforementioned style controller
BUT the new controllers like

17. Hysteresis
Audio from the RX to comparator where converted into a numeric
value then forwarded to Hysteresis module for switching then onto
The controller and out to transmitter.

20. Antennas Hustler G6, G7, HX6-14448 DB Products DB224E
Diamond X510 and others
Comet GP9 and others
Any antenna will work, look out for those that have multiple
couplings, Brass fittings with Caesar screws. These need to be
soldered over After tuning as they will produce snap, crackle, pop
in the signal as well as add potential de-cense.
