This blows up on 17M and the Ameritron wont fit. You will need something 
similar to what Amp Supply used or wind your own.

> TenTec Titan One
> Dentron DTR-2000

Unwind 3 turns from the top of the choke for 12M, other bands are OK.

> ICOM IC-2KL

No idea about the others.

Why remove the swamping??
