Re: Topband: Thanks!
Hi, Dean Well good luck in your hunt. Over the years I've found many uses for various Fair-Rite cores at HF. If you get the larger beads/tubes thatwill fit over RG-213 etc. you can make excellent 1:1 current baluns by slipping them over the cable before putting the connector on. You can hold them in place with "wire-ties". The ferrite is completely impervious to weather as far as I can tell. I've also used Fair-Rite cores to construct the input matching transformer in my home-brew 3-500Z amp and I've used smaller binocular cores to wind matchng transformers for 160 receiving loops. So, many applications for the cores - not just on Topband! :-) Have a good afternoon!

Hi Charlie: Thanks for the infos and the good wishes. Im looking at the fair-rite catalog and trying to come up with a good selection for experimentation when I run into RFI problems. Not sure how much of a ham market there really is, outside of the lowbanders. I never hear anybody else complaining about it. I guess the "buy bulk" advice is good for somebody, but certainly didnt address my question. 73 and TU again Dean W5PJR Tijeras, NM - Original Message - From: "Charlie Cunningham" To: dospi...@q.com, topband@contesting.com Sent: Saturday, May 18, 2013 10:17:18 AM Subject: RE: Topband: Thanks!

Topband: Titanex 160HD
They have also changed the diameters of the tubes, so any spares that you buy will not fit the older models. I just used some aluminium shims plus a bolt, and as long as you keep it tight it seems to work ok. I would also guy it twice. You could also try contacting Steffen Freitag DL6SFR as he has helped me in the past with contacting Titanex. 73 Steve, ZC4Li.

Topband: Titanex V160HD Sloppy Tube-Joints
Hi All and thanks for reading. When I luffed-over my 6 year old V160HD for it's annual maintenance check, it struck me just how sloppy all the various jointed sections have become. It's not that the securing bolts have become loose, they're still firm and tight. As owners will know, there are two doughnut shaped shims per section joint to adjust for the difference in tube sizes and it's the play between these and the tube ends that's the problem. I don't remember there being between a half to one mm gaps around the circumference in the past? I don't know whether new shims would fix it but Titanex no longer answer emails and I wouldn't know where to start trying to find an outsource willing to make me a few new ones to the required tolerances. Adding any more guys than the set I have at 12m is also a no go. The only thing I think may help, is to try increasing the tube overlap at each joint from the present nominal 5 inch to say 10 inch or more? Possibly adding an additional bolt at each joint also? I wonder if any other Titanex owners have had this problem and have any advice to share please? Many thanks in advance.
