[Repeater-Builder] Johnson Repeater Help

Hi,   Our group has acquired a Johnson 440 MHz repeater that they would like to convert to the Han Band.  There is very little data available on the web for Johnson’s.   My question is, what do we have?  There is a list of numbers inside the cabinet that probably are the part numbers.

RE: [Repeater-Builder] Battery terminal corrosion

Tim, I would agree with this approach, however, if the corrosion is not to bad, try using emery cloth to clean up the post and wire end terminals. Spray the items with WD-40. Re-assemble them and then use an aerosol battery terminal spray or brush on a waterproof type grease being sure to get unde

RE: [Repeater-Builder] Fuses on power cords

Budd, two fuses at the battery will pervert a car/truck fire if the ground wire comes in contact with hot wire of if the hot wire comes in contact with a ground. A diode will prevent frying the radio if the polarity gets switched. Al N8ARO I'm caught in the middle of a couple of feuding technic

I have a Micro Computer Concepts RC-1000 Controller.  I need a copy of the "assembly drawing" (I think) that shows the pinout of the Connector on the back.  I downloaded a copy of the manual, however, it does not show how to wire it up.   Anyone got a copy they can send me?  Thanks for your

Re: [Repeater-Builder] Re: Controler Pin Out

Thanks for the offer Coy. The web site has the manual for download, however, no drawings of the connector on the back. Several kind readers have sent me copies of the drawings so I'm all set now. Thanks All! Al, n8aro - Original Message - From: "ac0y5" <[EMAIL PROTECTED]> To: Sent: T

Re: [Repeater-Builder] 2m quad

Hi Sandeep,   I have made a 3 element quad for 2 meters.  I used 3/4 inch PVC (stronger then 1/2 inch) for the mast and got two of those fiberglass flag poles that you put on bicycles to use as the spreaders.  Just drilled apposing holes to hold the spreaders and used epoxy to secure them.

Boy Chuck, you're sarcastic! Unfortunately, you said what I was thinking. Al, N8ARO > I guess that the Repeater Builder list was so overwhelmed with Mitrek stuff > that it was inevitable that another list would be needed. > > I'm thinking of starting a list for users of 1/4 wave stainless steel

Re: [Repeater-Builder] Antenna support structures

Look for an antenna that is not in use.  Sometimes you can get them for taking them down.  Be careful, some are dangerous.   Al - Original Message - From: Stephen Slider To: Repeater-Builder@yahoogroups.com Sent: Thursday, March 18, 2004 9:23 PM Subject: [Re

Darin, get two ten foot sections of used tower sections at a swap. Made for your project. Strong, light and you can guy them for extra safety. They are made to bring the wind load down to the base. Al, N8ARO - Original Message - From: "Daron J. Wilson" <[EMAIL PROTECTED]> To: Sent:

Re: [Repeater-Builder] Radio Mounts

Daron, I guess I didn't know exactly what you wanted to do. Are you trying to stack the radios? I went to a CB store and then had lots of brackets and hump mounts. I like the hump mount because it had little teeth that hold the base on the carpet without moving, and had a built in 5 inch speaker

Re: [Repeater-Builder] grounds & cadwelding

John, Your idea sounds great for an RF ground system for your radios, however, it will now leave you radios as a ground path from the house, power lines, phone etc., to the great new ground. Be sure to disconnect all equipment from the ground and antennas when not is use. Go to: http://www.polyp
