Though I have a couple of bearings, I've just let the rotor carry the static load.

My antenna will be vy light (Spiderbeam) about 20 lbs & about 3.8 sq. ft. area to the wind. Rotator is Ham IV or Ham M. So, vertical static load not an issue. I like the idea of using a PVC reducer in the sleeve, sized to match mast. Reasonably low friction & tough material & cheap! Recall that I'm putting about 2 sections of tower on my roof. * * * My next step is to learn about non-steel guys, Dacron or Phillystran or whatever marine yards use. I have lots of antennas on my roof, don't want conductive guys to interfere with any of them. This stuff has to handled differently. E.g. no knots, I'm told it weakens the strength to 60%; that's why sailors would rather splice than knot. Need to use thimbles and curved metal loop-makers and special crimps, don't want to bend this kind of rope in too small a radius. I will be able to use rather shallow guy angles, considerably less than 45 deg. from the horizontal, that'll help everything. High UV resistance is an absolute must: altitude & latitude & # of days of sun--all high here. Any experience with this?

The filter had failed completely producing the peculiar smell of a burned out transformer. It is a potted unit that would have to be replaced as a whole. The procedure requires the removal of the subchassis where the antenna, power, audio etc connectors are located. The subchassis is removed from inside the main chassis and then some more disassembly is required to reach the filter assemblies. Bypassing filter Z802 is then just a straight forward procedure. The SRR12 is back to normal with that nice frequency projection system and excellent reception.

To: Old Tube Radios MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Jim and Others: The "Matchstick" was an all band, remotely switched, motor driven, vertical antenna system which covered the 80 through 10 meter bands. The vertical element was 35 feet long, and a tuning unit was mounted at the base of the antenna in a weatherproof box. The system even came with 6 fiberglass guy wires. Your friend apparently has the "indoor control box." In the ad I'm looking at on page 92 of July 1957 QST, Johnson claims SWR of 2:1 or less on all bands. Price at that time was $129,50, On the same page is an advertisement for their array of single band beams. Today you see that a number of companies, (MFJ, Hy-Gain, DX Engineering, etc) are offering 43 foot, all band antenna systems. Well, Edgar F. Johnson and his crew up at Waseca, Minnesota were over 50 years ahead of the game! 73 Don K8MFO In a message dated 5/26/2010 10:43:20 P.M.

Now I have to dig into my R1051B that has been dead for a while probably from a power supply problem. I always dreaded the day when I would have to work on it but it's about time. 73s Guido KP4FAR -----Original Message----- From: owner-boatanchors@theporch.com [mailto:owner-boatanchors@theporch.com] On Behalf Of Joseph Pinner Sent: Thursday, May 27, 2010 10:52 AM To: Old Tube Radios Subject: Re: SRR12 Revival Ah yes - I had to do that years ago on a SRR-11 that I had. It started smoking one day and I had to quickly shut it down. Bypassed the AC filter and we were back in operation. I don't have that sent any longer, but still do have a SRR-12 and FRR-23. They are some of my favorite receivers (thougth the SRR-12 needs work again).
