[Amps] Amps Digest, Vol 208, Issue 9

[Roger D Johnson]

The original purpose of this relay was to switch the input/output
from 52 Ohms when transmitting to 200-300 Ohms on receive to
better match the input impedance of the receivers of the day.

With modern transceivers with a 50 Ohm input on receive, this relay
is superfluous and can be removed entirely.
