My original Clipperton L did not have a tuned input. Thus it probably was
not 50 ohms on all bands. In those days, I ran a Drake T-4X transmitter who
didn't mind the mismatch very much. Lots of the modern transceivers have
either some kind of protection or an automatic tuner that should take care
of things. However, those protection things usually limit your output power
into a mismatched load; and some of the autotuners won't handle a bad
mismatch before they start to shut down. All of this is only what I hear
said on the air; I've never owned one of these rigs.
My current Clipperton L is said to have a tuned input; but, the guy who sold
it to me wasn't clear about that. And today I am still using a T-4X. To
prove something to myself, I probably should put my TW-1 between the
transmitter and the amp to see how it matches. But I guess my policy it to
just "let sleeping dogs lye".
The other thing to look at is the amount of current required to pull in the
relay in the amp and how substantial is the transmitter's keying (amp
switching) circuit.
Good luck with your venture. At the right price, I bet it's gonna be a good
one.
