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. ???
