Re: LF: LF SWR Bridge

["James Moritz" <james.moritz@btopenworld.com>]

Dear Stefan, LF Group,

The LF_tuning_aids.pdf file at 
https://sites.google.com/site/uk500khz/members-files/files I mentioned 
earlier contains some updated info on the LF tuning meter (extended to 
500kHz), along with the simple "scopematch", which displays voltage and 
current waveforms on a dual-trace oscilloscope, which is a very convenient 
aid to tuning if you have a scope in the shack. Also included is a simple 
resistive SWR bridge.
Although everybody is used to using SWR bridges, all they really tell you is 
if the antenna has a big or small mis-match - The tuning meter and 
scopematch give you reasonably accurate info about the actual impedance, so 
certainly make the job easier in my experience.
Cheers, Jim Moritz
