[Johnson] Johnson T/R switch TVI problems..?

[Jordan Arndt]

Hi... so what is the lowdown on the EFJ T/R switch...? Does a EFJ Low Pass
filter remove enough of the harmonics..? Adding a tuner should help, but I
live in a fairly congested area and would like to know more before I put the
switch in line with my DX-100...
DOes anyone know of a source of a DPDT Foot switch that I could use with the
DX-100...?
It has to be dual switched according to the manual.... 73 de Jordan...
