[Elecraft] RE: K2 Muting
Yes but what if you are using two K2's or K2 and another rig for that matter as twins recieving on one and transmiting on the other? is shorting the antenna jack out enough to protect the K2 from RF Overload??

Technically, this isn't a true SO2R setup -- when rig A is transmitting, you can't receive with rig B. Although, that's really difficult to accomplish with rigs in the same band. I'm using the W4AN arrangement - #1 rig both ears, both rigs, one in each ear (key line defeated for both) #2 rig both ears. When Bill introduced me to SO2R operation in 1995, he made the comment that he had practiced enough with two radios that he nearly always left the switch in the center position, with one rig in each ear. It did give him a headache doing this for 48 hours straight When your 'run' slows down, this arrangement lets you search for multipliers on the same band in between CQs, and enables you to check adjacent bands as well. In a true SO2R setup, you can search for mults and Qs WHILE you are transmitting a CQ. I have used this set-up with a pair of barefoot K2s in QRP contests only. Also, there are two sets of antennas, 80m through 10m, 100 metres apart. I use a simple SO2R setup. All the good antennas are connected to the K2/100. The second rig is a Kenwood TS-430S and is hooked up to an R7000 about 36m away from the tower. I also have a low dipole I can share between the K2 and the Kenwood.

Re: [Elecraft] Re: K2 muting
Hi, I'm very interested in this setup. If you could send a few photos and schematics, parts I'm actually searching for that solution before buying my second K2.

[Elecraft] Re: K2 Muting
Hi Bob, Do you want to do SO2R with the 2nd K2? I have been running two K2s, SO2R using either TRLog or CT with an old laptop and a W4AN type homebrew switchbox. The laptop has only one serial port, so I switch the KIO2 lines with a multi-pole relay - not elegant, but it works. If that's what you're looking for, I'll send details. 73, Ken ZL1AIH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
