[Elecraft] Diversity Recieve Issue

[Ken Nicely]

Back to the original problem.  I am pretty sure this is setting somewhere.
 I have discovered that diversity works fine on 40 meters, but not on 20 and
15.  On 40, if I am on diversity and I use and external coax switch on
antenna 1 and I switch out (disconnect) the antenna using the external
switch, the signal disappears in one ear.  If I do the same thing on 20 or
15, the signal disappears from both ears.  Any ideas?
