[ICOM] Pro II vs. Pro III RX-ANT input circuit: new link and erratum

[Adam Farson]

With QSL.net now restored, I have added this topic to my IC-756Pro3 User
Review.

http://www.qsl.net/ab4oj/icom/ic756pro3/pro3notes.html#rxant

Partial schematics are here:

I apologise for the error: "it will switch the receiver input line from ANT1
or
ANT2 to RX-ANT." This should read: "it will switch the receiver input line
from RX-ANT to the active main antenna socket, ANT1 or
ANT2."

Cheers for now, 73,
Adam VA7OJ/AB4OJ

<< The RX-ANT protection circuit in the Pro3 is actually independent of the
T/R state. When it detects excessive RF power input from any source, it will
switch the receiver input line from ANT1 or ANT2 to RX-ANT. >>
