I must correct my earlier post on Pete's question - faulty memory on my part
regarding the actual failed part in LA7NO's K3 T/R switch.  It was NOT the
PIN diode D25, but was instead the RF choke (RFC30) that provides
the DC path to ground that enables the 7T or 7R control voltages to select
the signal path through D25.  That choke failed open.

Mea culpa, and 73,

Mike, K8CN
