[Drakelist] +1 on the shorting load cap plates
Lee, I had the same thing happen to me and Garey's probably right. The plates on the loading cap are VERY close together and I did find one slightly-bent one. I put it on the bench, no power, turned the control and could hear the plates scuffing. I had to use a magnifying glass and strong light but I did find it. Your setting on the high bands are probably a far bit away from where they are on 40 80. 73, Steve Wedge, W1ES/4 To be is to do - Socrates To do is to be - Plato Do be do be do. - Sinatra All my computers have my signature with various pearls of wisdom appended thereto. ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] +1 on the shorting load cap plates
Steve, Yep, Mine was not shorting...but I think it was so close it arced overI wound up straightenimng 3 plates. They were only out a very, very small amount. I now realize the bug was there before...I just recently moved to a non-restricted QTH...so now I have 80/40 mtrs antennas. So, I guess this bug was on the TX when I got her, 6 years ago. I'm a pretty good technician...But...the way it acted...was at just about the peak on load is where it failed..so I did not think of that problem because it was so close to peak...I was sure it was something of a 'resonance' issue. Glad it was not. Moral of the story...don't forget the simple mechanical issues! Garey, as usual nailed it fist time. Thanks again Garey..your a smart guy for sure. 73, Lee, KC9CDT -Original Message- From: Steve Wedge w1es1...@earthlink.net To: kc9cdt kc9...@aol.com Cc: Drake List drakelist@zerobeat.net Sent: Mon, Mar 7, 2011 5:34 pm Subject: +1 on the shorting load cap plates Lee, I had the same thing happen to me and Garey's probably right.

[Drakelist] 8 pole filter
Why is an 8 pole 5 khz filter better than a 4 pole, since they're both 5 khz? ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] Thanks
Hi Gang, Sorry for not responding to all the nice people that helped me with some of my Drake woes. I've been working on a UV-3 for around six months. I had to replace countless parts, one of which was due to a dumb mistake. I inadvertently shorted 12 volts to the 5 volt line. That cost me a divider board, and many, many hours of head scratching. The UV-3 now lives. Next on my agenda is the X-Lock installation in my TR-7, I had already stuffed all the electrolytic caps, and boy did I make a mess swapping them for the Tantilum Caps after finding out the hard way that there isn't room for the tall caps. Yikes!!! Again, thanks for all the help Enjoy those Drakes.. Tom Maguire, WD8JPP ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
