Eric closed the G5RV thread, so I will change this subject as it is not
related to the G5RV.

It's true that tuner losses are the manufacturers' dirty little
secret. Loss is rarely specified, partly because it can be pretty
bad, and partly because it is hard to measure, but also because it is
not constant - it depends on the particular impedance being matched.
I read about tuner losses often, and I've seen figures posted, but
whenever I try to determine it, I can't. The only way I can determine
tuner loss is by signal reports. While participating in round tables
on 80 meters, I go down in power as low as the K3 will go, and the
participants in state, and in an adjacent state or two, still hear me
as evidenced by carrying on a discussion. I use open wire feedline
with a loop cut for the bottom of 80 meters.
I know this is not an accurate way to measure tuner loss, but the loss
doesn't seem to be a problem. ???
