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.

Subject: Re: [TowerTalk] Which Balun with the TH7DXX
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.
