I think Johnson also used to make a 3- or 6-dB power attenuator - there's one buried somewhere in my garage, that I used to allow driving a Hallicrafters 6M transverter with my Kenwood TS-900. It is comprised of a large collection of carbon composition 2W resistors. But it's been about 25 years since I did that, and for sure, I don't recall all of the details, other than needing an external coax relays to make it all work with that transverter.

There was an article that used the station dummy load as the primary part of a RF divider to send to the station's tuner. It would provide at worst something like a 2:1 SWR. Something like a 100 ohm pickoff going to the tuner. With infinite, your rig basically saw 50 ohms, with 0, your rig saw 50 and 100 ohms in parallel (33 ohms). Does anyone remember an article like this? If so please let us know. It looks like that might be adaptable for situations like this. 73, Ron WD8SBB _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
