[Drakelist] experience with TR-7 CW filter
I am considering buying a 300Hz filter for the TR7 and wonder if any of you guys out there have experience with that narrow filter. Does it ring excessively or have excessive insertion loss? Also, would you recommend an new InRad filter rather than a used Drake original filter?

Re: [Drakelist] experience with TR-7 CW filter
I've got the 400hz InRad (I think that's it) and it's quite narrow. I can't imagine needing more narrow than that. I note no excessive loss with the 400hz Inrad or the 500hz Drake...

[Drakelist] R-4x antenna coil slug
Hi foks, If Garey, our guru on these, things is by chance well enuf to be monitoring, we hope you're doing well. I'm into a local fellow's R-4A, and noticed the antenna xfmr, T-1, had the slug set lower in the coil than the others, by abt 1/4. In order to re-adjust it, I removed it, and found it looked like it had been broken off. Checked the Inj slug, and they are ~ 1/4 different in length. The Inj slug has a nice square end, the Ant one has a broken looking end. (the piece is nowhere to be found, it's not down the hole.) Anyhow, does anyone have a junker rcvr with a donor T-1 slug? Or know of another of the same mix length that could be used, even if epoxied to the wire? I have a junker TR-4, could get s slug from an xfmr in it, but it doesn't have the same rack/slug arrgt. tnx, 73, Al, W8UT New Bern, NC www.boatanchors.org www.hammarlund.info there is nothing -absolutely nothing- half as much worth doing as simply messing about in boats.

[Drakelist] Manual Problem
This is not really off topic because it deals with Drake manuals also. Many of the free manual copies on the internet were scanned on 8 1/2 by 11 size-limited scanners because they are inexpensive and work well. That leaves larger schematics (11 by 17) with two or three pages that have to be spliced. Is there a software program that can stitch those pages back together to print an 11 by 17 for example. How about Adobe Acrobat? I have been trying to find out on their website but wading through all the 'select this or that and then wait', I can't figure it out. Is there a quick answer?

Re: [Drakelist] Manual Problem
The best way would be with Adobe Photoshop, starting with a relatively high resolution file, or simply take a digital picture (again relatively hi-res), evenly lit, of the complete 11X17, or whatever size it is. In the biz we call it copy art. Rick W9WS On Aug 10, 2009, at 6:57 PM, Donley wrote: This is not really off topic because it deals with Drake manuals also.

Re: [Drakelist] experience with TR-7 CW filter
I have the 500 and 300 Hz filters in my TR7. I found the tuning to be a bit sharp with the narrow filter using the TR7 VFO, but with my DDS VFO the tuning is very slow and the filter is much easier to use. It doesn't ring any more or less than any other narrow filter I've ever heard and I haven't found the insertion loss to be a problem. 73, Floyd - K8AC - Original Message - From: Dennis Monticelli To: drakelist@zerobeat.net Sent: Monday, August 10, 2009 2:06 PM Subject: [Drakelist] experience with TR-7 CW filter I am considering buying a 300Hz filter for the TR7 and wonder if any of you guys out there have experience with that narrow filter.
