[Kenwood] [KenwoodTS-2000] TS2000 and duplexer problem

[John Geiger]

I did try it on another 2m mag mount antenna and it was putting out the full 100 watts there, so it must be some interaction between the duplexer and the antenna.  Not sure why it would work on 1 antenna but not the other.

Since it uses a common feedline for both bands, I use a duplexer at the rig end to accommodate the separate antenna jacks for 2m and 70cm.?? This is where the problem occurs.?? With the duplexer in line, the power on 2m drops to 60 watts out-I assume due to the rig seeing a high SWR on that band.?? With the duplexer gone and feeding the antenna straight to the 2m jack, it is putting out full power on 2m.?? I have tried 2 different duplexers and have the same problem with both of them.

Have you tried it into a dummy load?
