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.
