[Drakelist] RCS 4 switces

[Drakelist] RCS-4 antenna switch
I have two Drake RCS-4 switch units and three control heads for sale. One was originally purchased by me in the late 70's and may have a bad component in the control head. One control head and switch checked out okay a few years ago but I am selling all as is. I used the one I bought for at least 30 years and it was an excellent product. You mount the switch at the tower and run one coax and an 8 conductor cable (such as rotor cable) to it and it will switch 5 antennas and handle a KW. I have the manual and schematic. Asking $125.00 plus $25.00 shipping in lower 48. Rick, W0RT ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] RCS-4
Partial success. Abbatron/ H.H.Smith Part. No. 874 were a direct drop in replacement for the original binding post board (a.k.a. terminal strips). Got them replaced and then hooked up the control head and applied power. The lights come on, the motor break releases, but the motor won't turn. Disassembled the motor and gear box. The gear box had all the grease clumped together, but it was dry and nothing corroded in it. All the gears are in good shape and move freely. The motor itself turn by hand with some resistance, but it will not turn when power is applied. Any suggestions?

Re: [Drakelist] RCS-4
SUCCESS The key to it was from my description of the insides when I first opened it up. Not only was the motor frame rusty on the outside, it was also rusty on the inside where the rotor needs to turn (so of course, it wasn't). Completely disassembled the motor and gently took a file to the inside of the rotor housing. Works like brand-new now. Still going to clean the switch contacts before I reassemble, although they seem to be fine with it stopping properly for each switch position. Now to tackle the CD-44/Ham II while I wait for my order of DEOX-IT to come in. That should only require replacing rusted hardware since it has sat in my attic for the better part of 20 years. I may actually get these antennas up by fall. Loren - WA3WZR On 8/17/2011 10:07 PM, Garey Barrell wrote: Coil continuity??

Re: [Drakelist] RCS-4
I've found that any antenna, tower, rotor, etc. device used outdoors can benefit from the use of stainless steel hardware, nylon insert locknuts as appropriate. You can buy it online at a price, including shipping, that is less than what you can buy locally for standard, plated hardware. -Original Message- From: Loren McCullough loren...@verizon.net To: Richard Tucker ri...@wavewls.com; drakelist Drakelist@zerobeat.net Sent: Sun, Aug 7, 2011 11:11 am Subject: Re: [Drakelist] RCS-4 Finally got the switch box apart.

Steve WA9JML I can't find Kroil locally. You can get it from the manufacturer on the web, I am not sure what the minimum amount is. I have a can of their Microil, a highly refined petrollium based oil suitable for instrument use. Kroil seems to be universally recommended as the best penetrating oil available. There are some others; I've had decent results from Liquid Wrench, you sometimes need to use many applications over a length of time, days or even a couple of weeks. Not sure of Kroil works any faster. There also used to be something called Marvel Mystery Oil which had a reducing agent in it (converts oxide back to metal) reportedly hydroquinone, also used as a photographic developer. I used to see Marvel at Pep-Boys but have not looked for it lately and don't know if its even still made. Beside applying penetrating oil try heating the rusted parts a bit, that may help the oil to penetrate. Also tapping on them can help because the vibration can help the oil to wick into the rusted area. -- Richard Knoppow Los Angeles WB6KBL dickb...@ix.netcom.com ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

I haven't really looked at either piece yet. The control head has been sitting in my attic for abt 20 years and the remote antenna switch has been sitting outside in the elements. Off subject, I also have a Ham-II/CD44 rotor and control head that is in about the same situation except that the rotor has been in my attic since the tower crashed in the late 80s. Would like to get them both back in operational condition.

[Drakelist] RCS-4 External Antenna Switch
Hello everyone, I just acquired an RCS-4 antenna switch that works. Does anyone have any advice on whether I need to lube the drive motor, and if so, what to use, and how to do it? Any other advice on other items I should be concerned about? Thanks and 73 Mark N5KAE ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] RCS-4 External Antenna Switch
Mark, RCS-4--I have used one continuously since the 1970's, I have never lubed it. I have disasembled it and cleaned the ant nests out of it and cleaned the contacts on the rotary switch with deoxit. I bought a used one at a hamfest and finally had to start using the control head from it. I think the transformer may have burned out in my original. It is slow in extremely cold wx but still works fine.

Re: [Drakelist] RCS-4 External Antenna Switch
I, too, have had one in use for years - the wireless type. The external unit was sealed with the silicon caulking used ariund tubs. Never a problem. They are really nice gems. I'd like a two position one if anyone has one.
