[amsat-bb] Accessory to add CTCSS tone?

[W3AB/GEO]

PL tone transmit is different than tone squelch. Tone squelch is used on the RCVR side to squelch out unwanted signals. The radio receives them but they don't break the squelch circuitry. You may notice a "MON or MONITOR" button on the radio. That temorarily disables the tone squelch circuit to be able to check for channel activity.
