I have acquired a Johnson T-R switch and during testing at
3.5+ MHz. and about 100W into a good dummy load, with the
receive port terminated with 51 ohms I'm seeing an initial
level on the order of four volts peak before the 6BL7 shuts
off and reduces the level. Is this normal? If not, what is
normal?
Thanks. 73, Bob AD3K
Are we talking about RF here?
