Topband: Tuner balun

[rick darwicki]

Hello all,

I have a WM. M. Nye 3000 Watt tuner and see that it uses a PI network and Tri-Filar Balun on the output. The Balun is in the circuit on coax, single wire and twin led output and is supposedly rated 1 - 30 mHz.

I only use coax and have baluns at the antennas.

The tuner gives me a 1:1 SWR with a pretty broad bandwidth on my 160 inverted L ground plane with a DXE choke at the base. The problem I have is I cannot get the SWR below 1.5 - 2 from 1800 to 1810 and I want to try some RTTY.

I hoping to solve the problem without going on the roof or taking the antenna down.

Your thoughts on deleting/keeping the balun would be appreciated. 

Rick, N6PE
