[Elecraft] P3 Newbie needs help.

[Alan Bloom]

If the frequency display at the top center of the P3 screen is reading 
zero, then that implies there is something wrong with the RS-232 
connection between the K3 and the P3.  Recheck the connections on page 5 
of the P3 manual:

The two-headed cable should plug into the two RS-232 connectors on the 
P3 in the order shown.  Make sure all the connectors are well-seated.
