Re: SEARCHING FOR CAPS

The older Flash Technology strobe lights use almost the same value cap. 1.0uf @ 2500 vnp. Here is one source for them, but no price listed. There are other sources for these and I have even seen new ones on Ebay. 1mf 2.5kv Night Capacitor Direct OEM replacement for the following systems: Honeywell /...

Re: Reviving a dormant antenna system

I agree that Mark is giving the best advice engineering wise. But money wise and who isn't these days why not pressure it up, load into it and see what happens. You won't waste that much time testing it, maybe will still work.

Re: FM Clock Radio with good blanketing protection recommendation

There is no clock radio ever built that has those qualities. Get a good radio and connect a radio shack timer to it. :)

Re: How Old is Old?

I'd agree with Kelly and replace the rigid line with heliax. Your tower crew is going to cost plenty no mater if they re-hang old line or new. In fact new line would be less crew time as they don't have to bolt all those sections together. 35 years ago when I started in this business they were build...

Re: Scala FM Antennas

These antennas are well built and will last many years. If you put it up mounted vertical and aim it at one market you need to cover it will be fine. If you try multiple antennas you will have a mess of coverage, I recommend not doing that. Instead buy a Nicom or other broadcast antenna designed to ...

Re:UPDATE: Rebuilding a Lighting Choke

Eric tells me he received and installed the Kintronic choke. He is pleased to report that his before and after parameters did no change. Even the mounting holes lined up making for an easy install. Thanks to all of you for helping with this problem.

Re: Utility Tower

I know this is a long shot but does anyone have a copy of the original plans for a Utility Tower Type 120? Thanks in advance! Larry Milliken I contacted the company a few years ago, they were still in business and happily supplied a drawing of our 20 year old tower no charge. It would probably help...

Re: Phelps Dodge Antenna Rebuild

You could try to re-sell it to a station on channel perhaps as a stand by and recover some of your original investment. They wouldn't have to invest much to get in service.
Don't feel too bad about spending money on a bad buy. We have all done it, especially on used or e-bay equipment.

Re: Rebuilding a Lighting Choke

Well after considering all the options discussed here, he chose to have Kintronic build a replacement. $1100 vs. $3500 from Gates Air. Thanks to all of you that posted on this.

Rebuilding a Lighting Choke

My previous assistant is faced with a shorted AC lighting choke. The last time we replaced one of these it was very expensive ($3500) and took like two months to get it. So he is considering rebuilding it, but not shure what to use for the insulation between the windings. I thought maybe that orange...

Jay Crawford of Cincinnati Public Radio passed away, I don't know the details yet, but the last time I talked to him for some help last Fall, he returned the call from his hospital bed. We had bought a station in Rodgers City Mi. he used to engineer. Even tho...

Re: The Looming Engineering Age Crisis

Unless the 'younger' engineer has greater seniority with the company, they could be in violation of labor laws releasing anyone older than 55 due to financial reasons (reduction in force), without releasing the 'younger engineer at the same time. Title of duty does not excuse the company when the d...

Good luck with that! :lol: I'm gonna be 78 next month. I predict you will start going bonkers within two weeks, or so, after you retire and long for the day when you can get back to the smell of molten solder.
