[TowerTalk] Which Balun with the TH7DXX

[Jim W7RY]

I regularly run 1500 watts RTTY contesting to my TH7 with a BN86. Works 
fine.

I tried 8-10 turns of RG400 on a FT-240-61 core and the SWR was not nearly 
as good as it was with the BN-86 as Gerald has pointed out here.

The TH-7DX is sold with a BN-86. I immediately replaced mine with the
BN-4000, which handles more power.

I regularly run legal limit into my TH-7DX/BN-4000 without any problems,
even on RTTY.
