Johnson T-R switch receive port output levels?
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 |
