    Hey Rege, you have another link for that file, that link doesn't seem to work.

    Yeah, most of the stuff I would use this for would be QRP related, or maybe with one of my SDR receivers to switch amps in/out. If you look at the last page of the PDF though, it looks like from UHF to HF frequencies, it could do 200w all day. Pretty cool.

    Your in Winnetka, ca so I'm sure you've been to the TRW swap. It's been about 6 months or more since I've last been, but I sure love to go.

    I sure miss the TRW of my first activities as a new ham in 6-land.

    Yes, I've been to "TRW" swap meet many, many times -- used to "sell" there quite a lot back in the late 80s through late 90s. Haven't sold there in several years now.

    One of the last times I had "tables" there to sell was in maybe '99 or '00 and about 7 AM spotted a familiar figure walking the meet: Joe Walsh, WB6ACU. Bob Heil K9EID was also there, and Joe was looking for Bob.

    I called out "Joe!" and he came over to my setup and bought some stuff. Always with a smile and a "How ya doin"?" Cool guy.

    I worked at a TV transmitter plant that used 4 port switches to select the transmitters to the antenna and the antenna configuration main, aux or dummy load. Had 12 of them all with 3 1/8" hard line.

    This switch type with SMA connectors was also used in Nurad 2 GHz ENG antennas to switch polarization ( H, V, CW, CCW). A near by lightening strike would short steering diodes and the switch would run like a motor for a little while before burning up.
