Have to send this out to Bill Max and Ryan Gill as they had been building these interface boxes.
Bill is a local WS19 guru who has calculated the R and C for impedance matching against the modern mics and headphones.
Ryan has been developing the interface for the WS/19 IC and call boxes for the Humber.
Likely the same for use in any of the Brit AFVs.
Let me ask them and see what we get back.
Probably should come up with a "white paper" on How to add a CB/FRS/GRMS radio to your WS/19 -equipted vehicle" .... or some such..
To add, our club does participate in field tacticals, so we need to be able to use real radios between vehicles and ground troops, and the CB/FRS/GRMS radios are legal to own by civilians with no license.
