[Drakelist] T4XC drive
Last night, my T4XC was providing full output on cw regardless of where the drive control was set -- even all the way CCW. Normally, on cw you have to advance it beyond 12 o'clock for full drive. I checked and double checked all switch settings, etc. Any suggestions? Thanks Rick W0RT___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] T4XC drive
Hi Rick, Sounds to me like your finals are ...taking off somehow, i.e. oscillating... What does the monitored signal sound like...? Is it exactly as displayed on the frequency dial...? Is it raspy-sounding / unstable...? Those are all sure-fire indicators that you have an instability issue with your rig there! ~73~ de Eddy VE3CUI - VE3XZ *** - Original Message - From: Rick Tucker To: drakelist@zerobeat.net Sent: Thursday, January 07, 2010 9:10 AM Subject: [Drakelist] T4XC drive Last night, my T4XC was providing full output on cw regardless of where the drive control was set -- even all the way CCW.

Re: [Drakelist] T4XC drive
Rick - Check R105 and R106 and associated wiring for continuity and value. If R105 opens at the bottom (ground) end, R106 or its wiring open up, full drive regardless of GAIN control setting. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com Rick Tucker wrote: Last night, my T4XC was providing full output on cw regardless of where the drive control was set -- even all the way CCW.

[Drakelist] FS: Unique Drake Service Supplement CDs
Here is the information that Drake left out of their manuals! Unique supplemental service information CDs available for the Drake TR-4, TR-4C/Cw/CwRIT, B and C Lines and the 2-B receiver. High resolution color photos of the under chassis and individual PC boards of each unit, with all parts identified and keyed to a parts list make it easy to locate any component. No more trying to trace wires through bundles, etc. This information is not available elsewhere and really makes a difference in servicing these units. These CDs are NOT just scans of the original manuals that were included with the equipment when new. High resolution scans of the original manuals ARE on the CDs, along with scans of manuals for associated equipment such as the C-4, FS-4, MN2000, L-4B, W-4, etc. Samples of these pages (at reduced resolution) and purchase information are at www.k4oah.com. -- 73, Garey - K4OAH Glen Allen, VA ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] tr-7 readout replacement
Hi Dale, Thanks for the complements. Honour goes to my good friend Rien - PA0TRT, I only placed the info on my homepage. I've never heard of a puller for the DR-7 board. I use this one by pulling the rear side of the board first, after disconnecting all wired connectors. In my TR7 there is enough space to remove the complete board carefully without unfastening the front or other parts. Carel.

Re: [Drakelist] FS: Unique Drake Service Supplement CDs
I will vouch for Gary's fine work . It is the heart and soul of the hobby. I bought the TR-4C-rit and C-line CDs. Aside from the utility, they are great to just look at. The additional files on Adverts. and Brochures are also great to read. 73, Kris (KA2OIG) Merschrod 123 Warren Road Ithaca, NY 14850 www.merschrod.net - Original Message - From: Garey Barrell k4...@mindspring.com To: Drakelist drakelist@zerobeat.net Sent: Thursday, January 07, 2010 12:47 PM Subject: [Drakelist] FS: Unique Drake Service Supplement CDs Here is the information that Drake left out of their manuals!

I second what Kris said. I have the R-4B CD, and it makes life a lot easier 73 Jim WA8SDF On Jan 7, 2010, at 3:03 PM, Kris Merschrod wrote: I will vouch for Gary's fine work .

Re: [Drakelist] tr-7 readout replacement
This is the page that I used to make my copy of the Drake board puller. It works well for the plugin cards, and is a must-have. For the DR-7, I still recommend a PC slot cover. They work as if designed for that task. 73 -Jim On Thu, 7 Jan 2010 07:50:47 +, Carel PA0CMU wrote: For a DIY board extractor, see this: http://members.ziggo.nl/cmulder/drake.htm#bookmark9 Good luck, Carel - PA0CMU -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
