[PVRCNC] kk1l antenna switch mod,<resend>

[KAZeringue]

It seems like I remember a couple of you have the KK1L antenna switch 
project.

AC0C has a good page about this switch.  Down towards the bottom of his 
page he describes how a simple mod will smooth the SWR curve for the 
upper HF bands(at the expense of 6 meters, where the inductive reactance 
of the mod is too high).

In summary, the mod is to add a small coil on the A and B ports to 
cancel the capacitive reactance of the switch.  Makes me wonder if I 
should check the sixPak too.

Good info on the project - and I also noticed KK1L's parts list for the 
project now specifies one of the P&B/Schrack relays I suggested as drop 
in replacements for the Zettlers.  The P&B DPDT relays might be the 
better choice, both poles tied together give a slightly better current 
rating, and the board is designed to tie them.
