reactors

[VK2BDR]

Does anyone know if discharge lamp ballast/choke/reactors may be suitable as modulation reactors. There seem to be plenty of these things around and for a 100 watt class rig the isulation seems pretty good. Only thing is the lamp industry doesn't seem to have any idea as to the inductance!?

Hello DS
Waiting for the sunspots to go back up so we can chat!!
You can use filter chokes in series for mod reactors. There will be a series reistance included to drop a little B+ to the final RF PA, though. But I wouldn't think that there would be saturation in a mod transformer in a table top Ham transmitter.
Saturation usually happens in the higher power transmitters. I can't remember the specifics, but to allow for the higher audio freqs for hi-fi audio from a broadcast transmitter, the secondary can saturate and there goes your pos peaks.
