DXE makes good stuff, but your problem is unlikely to be related to 
the balun/choke. The more likely cause is a pin 1 problem in one or 
more of the pieces of gear in your station, including the radio 
itself. 

If you still want to improve the choke, you can easily build a 
better one than you can buy, even from DXE. Wait a few weeks for the 
updated cookbook (part of the tutorial at the link above) that 
Ill publish after Ive finished measuring some more chokes.
