Help with rotator CDE Model H-IV CD-45-II
I have the Rotator CDE Model H-IV CD-45-II. But I have to open the rotator to modify old cables and since I haven't use it for a while I'm having trouble to calibrate the same.
How I calibrate ? I have tryed and no luck. Can anyone help me with a manual or an answer.
If you go to the Hy-gain (MFJ) web site www.hy-gain.com and click on manuals they have a .pdf file of the manual for your rotator.
Thanks OM for the help. Already print the pdf file, now I have to read it
Back again ... Enclosed are 2 pictures as you can see the needle in the center it shows the north. Now:
As you can see the neddle inside the rotor is way bak on the upper top part.
I can go S via West to North and back gain, but I nevercan direct to the South via East. It only gives me south via West to north and north to south via west, looking at the picture only the left part of north.
How can I go both ways ? where I have to put the needle inside the rotor ?
I hope you can undersatnd my question. Sorry for the englis
Look for an answer soon .... I nust put my antena up soon ...

I think the newer manuals that you can download from Hy-Gain do not have the disassembly/re-assembly instructions.
Go to the BAMA website http://bama.edebris.com/manuals/cde/ and download one of the older manuals. I think that will answer your question.
Did you only replace the cable, or disassemble the entire assembly from the outer housing?
It sounds like youy didn't get the housing (top part) properly aligned with the arm on the variable resistor that indicates the direction. It takes a bit of patience and care to properly align the top housing with the resistor arm.
I hope I understand. The top housing will put some pressure on the resistor arm so it makes better contact with the resistor element; try carefully cleaning the resistor element of all grease and dirt; it sounds like the arm isn't making good contact. It's also possible that the resistor is worn out and may need replacement.

IF the pot is shot, you can get a new one from hygain.......I have a HAM-IV which I bought used. I took it apart, cleaned it, and lubed the bearings. I works fine luckliy. Hygain Rotors are VERY easy to get parts for from hygain. At worst case, you can send it to Norm's Rotor service and for a nominal fee, they will make it like new...
