Thank you....That is what I understood also...I'm not saying I'm gonna be running the repeater at full blast, but according to the service manual, there should be actually around 43 watts out + -. BTW, I noticed it fluctuating again today....hits about 27 watts for a second, drops to 3 or 4, jumps back to 15...might stay at 15 for a while then might go back to 22...I can just sit there in test mode, with XMIT on, not touching a thing, and watch the bird jump around. I've tapped and bumped and juggled everything I can imagine other than taking out the boards and cleaning all the contacts. Ken, what about that power adjustment VR1, I really don't know what I should be doing with that. According to the service manual, that is the place to get the output power up to snuff, but I can't get the thing to budge or move or anything. I'm wondering if that "pot" or whatever it is might be the culprit for both problems. > > > >> Question 3...The CW ID turns itself on every "X" minutes regardless > >> of how I set it in the software...am I missing something?

I agree with your first statement in the above paragraph. My SWR is flat going into my dummy load...however, that's not saying that my load is bad and possibly my meter as well. I've not had someone else check things with different equipment. I did do this though. I replaced my load with a yagi antenna and I noticed that now when stable, the power is at about 22 watts or so. Cables are FSJ1 from the TX out to the meter and then a short run of RG214 to the load. Duplexer isn't even in the picture yet. > > Ken > ------------------------------------------------------------------- ----------- > President and CTO - Arcom Communications > Makers of state-of-the-art repeater controllers and accessories. > http://www.ah6le.net/arcom/index.html > Come see us at Dayton 2005! > We now offer complete Kenwood TKR repeater packages! > AH6LE/R - IRLP Node 3000 > http://www.irlp.net Thank you bunches folks!
