The box switches 52v at 100ma. Will the relay connection on the back
panel "Relay (N.O.)" handle that voltage and current?
The Omni Six's external keying relay will switch this voltage and current,
but I recommend using a solid-state switch or high-voltage output transistor
keyed from the TX OUT.jack using an RCA "Y" adapter between TX OUT and TX
EN. The third plug on the adapter is then connected to the solid-state
switching device. A 1N4148 steering diode is part of the TX OUT signal
line and provides further isolation.
When I owned my Omni Six, I used a 2N5551 HV transistor mounted internal to
the Omni. However, two commercial circuits are available to make the job
easier for those who would rather not modify the radio:

Using one of the above methods, keying from the Omni will be much faster and
quieter than using the internal relay.
