It should have 1 pole and 6 positions but any number of positions will do provided the stop is adjustable. The body is 2 in diameter and size is critical since it is under a 2 inch chassis. What is currently there is a CRL 231-006. Any help will be appreciated.

Re: [AMRadio] You gotta LOVE IT
Hello Bob - sorry to hear about your problems with the ATT U Verse technician. I also work for ATT, however I'm a System Engineer on the Mobility side, so I don't have much experience with our U Verse product. Also, I am a Ham too and I find the technician's complaint highly suspect. Have you contacted the U Verse technical support and discussed the technician's comments with them? I'm curious to know what their reaction would be. If you have not contacted technical support yet, that would be your first step. If the first person you speak with does not offer to have other personnel come out to assess the situation, you should request to speak with a manager and ask them to escalate the issue. If you can't get anywhere with this issue, please let me know. I can try to get in touch with the right folks within ATT and escalate the issue for you. My work email is dp5...@att.com. My work phone is 405-301-0049. Let me know what I can do to assist. Thanks Dennis Pharr WD5JWY On 5/8/09, Bob Peters rwpet...@swbell.net wrote: Hi Guys and Gals. Got a good one for the group. I had ordered ATT U Verse to be installed today.Tech got here a bit ago and took one look at the shack and said NO CAN INSTALL you are a Ham Radio Operator and will kick the you know what out of our system. The U Verse cannot be close to any RF Environment. Now tell me if that is not the biggest piece of B . He said that HAMS create all kinds of problems for them and that the FCC is looking into what to do to help ATT on the problem. Looks like we have another BPL on our hands here.

RE: [AMRadio] ground sticks again
Amen to that Dave! In an earlier life, I was a Broadcast Engineer for about 15 years. During that time, I worked on everything from 250 watt AM to 50KW AM and on to 100KW ERP FM transmitters. I've worked with virtually all the known manufacturers gear from Raytheon to RCA and Collins to Continental (one in the same). Not once, not ever, did I see a grounding stick with a built in bleeder resistor in any of those transmitters. And there was a very good reason for that - none of the manufacturers wanted to deal with the lawsuit that would have resulted from an Engineer being killed by such a dangerous idea. When I worked on a transmitter, I always kept a bunch of new clip leads available at the transmitter site. After touching all the high voltage points in the transmitter with the shorting stick, I would keep the shorting stick on each high voltage point while I used a clip lead to short the point to ground. The transmitter would stay that way until I was ready to return it to service. I would much rather know instantly (from the spark and noise) that I have an open bleeder resistor. I can always go buy another pair of underwear. Bottom line - There is no component, no matter how rare or expensive, that is worth a human life. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of david knepper Sent: Monday, June 05, 2006 2:55 PM To: Discussion of AM Radio Subject: Re: [AMRadio] ground sticks again If anything, these discussion only point out that ownership of a broadcast transmitter is one thing; but it is another to modify, restore, and operate one by only those who know what they are doing!

RE: [AMRadio] ground sticks again
I knew someone would bring that up. No, I never did forget to remove the clip leads. If I had forgotten, then either the overload relay would kick out the HV or the transmitter would have blown a fuse - either of which could easily be repaired..if you're still alive. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jim Wilhite Sent: Monday, June 05, 2006 7:05 PM To: Discussion of AM Radio Subject: Re: [AMRadio] ground sticks again Hey Dennis did you ever forget to remove a clip lead and hit the HV button? 73 Jim W5JO When I worked on a transmitter, I always kept a bunch of new clip leads available at the transmitter site.

RE: [AMRadio] Millen 90902 info needed, please.
Craig: You might find something useful on the James Millen Society webpage. Although they don't have a schematic for a 2 scope, they do have schematics for the 3 scope (90903) and the circuit may be similar such that you could identify the value of the cap - good luck. http://www.isquare.com/millen/millen-page.htm Dennis WD5JWY -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Craig Roberts Sent: Thursday, February 23, 2006 2:55 PM To: Discussion of AM Radio Subject: [AMRadio] Millen 90902 info needed, please. Hey y'all -- I've just acquired a nice looking Millen 90902 2 monitor scope. It needs recapping, however. One of the caps is an oil filled device that's leaked its contents. I think it's a good candidate for replacement :-) The problem is, I can't read its value (the label's destroyed) and I don't have a schematic for this scope. Does anyone know what this cap is...or what might be a decent substitute. It needs a 1 KV rating.
