Re: Tower Lighting

I have had great luck with Maintenance Engineering lamps. H&H had a period back a few years were their marker lamps had poor life, in some cases as little as 3 months. I have a tower we used the Maintenance Engineering lamps on, and 2 1/2 year later, all the lamps are still burning.

Good luck!

ARC-16 problem

Yes, I know they are old as dirt and should be tossed out immediately, but budgets being what they are, i would like to try to get a few more miles out this one. It has what would appear to be a rather minor problem. Status 8 is stuck on. This happened last spring following a lightning strike and I ...

Re: Replacement dehydrator pressure switch

Thanks! I had spent about an hour looking, and did not come up with anything. The right syntax makes all the difference in the search returns.

Thanks again!

Replacement dehydrator pressure switch

I have a Andrew dehydrator that is in need of a replacement pressure switch. This is the low end unit with the external desiccant canister built by Gast, but sold through Andrew. The original part is a P61AA-35C by Johnson Controls, and appears to be NLA. A quick search at Granger does not reveal a ...

Bird 4600 wattmeter calibration

I have a Bird 4600 3 inch wattmeter with two slugs (15kb3 and 30kb3)that I would like to have calibration checked on. Bird wants approximately $475 providing no repairs are necessary. Does anyone have a call lab they can recommend?

Thanks!

Re: Gotta love Westwood One

An AM station I look after runs a morning show distributed by SRN. A listener called one day, and asked why we had ran the same show segment every day for the previous week. Initially, the station chocked it up to a crackpot call, but they did call me. I looked into it, and found that due to a netwo...

Re: Harris HT-10FM freq change

The odd thing is...Harris calls for the stub to be longer when moving up in frequency. I have not looked at what is going on with the filter.

Thanks!

Re: Harris HT-10FM freq change

The condition of the HT-10 is an order of magnitude better than an old Continental 816 that it is replacing. The Continental has burned the finger stock on three sides of the deck twice in five years, and the management is tired of pouring money into a 31 year old transmitter. (I know the HT-10 is t...

Harris HT-10FM freq change

I need to change frequency on a HT-10 that is currently on 95.7. I will be going to 104.3. Harris has put together a comprehensive parts list that I currently have on order, with the exception of one item. There is a tuning stub on the output filter that needs to change, and it an item that Harris n...

Copper theft deterent

Yesterday I was called by a client on a AM-FM combo tower site that it looked like we had been the victim of copper theft. When I arrived I quickly confirmed that we had indeed had a significant amount of copper stolen. The 120ft 3" copper strap between the base of the tower and the TX building was ...

Re: RVR PTRL-LCD transmitter PS

Thanks to all that replied...the tip about the fan is great. I have another fan that I will substitute and see if that is the problem. The suggestions on how to proceed with troubleshooting are most welcome. I have repaired numerous linear power supplies, but have almost no experience with switchers...

RVR PTRL-LCD transmitter PS

I have a RVR STL transmitter with a defective power supply. The RVR P/N is FLY100SMD/5. I have not had much luck repairing switching power supplies, but would like to give this one a shot. RVR wants $375 for a replacement. Does anyone happen to have a diagram for this supply? Any experience with rep...

Re: High Intesity Tower Lights

RIch, We priced a Vigilante LED replacement system for a Flashtec HI system on a 690ft stick. The estimate with removal and installation was about 90K. At the time, the Vigilante HI LED strobe heads were approximately 3ft long, and they could not come up with a way to mount them on the top of our ER...

Re: The-1 or FX-30

The FX30 is a great exciter. The THE-1 has better low end frequency response, but is much more difficult to work on. If you can get by with 30W drive, I would vote for the FX30. I had occasion to put one on the air that had not been powered up in over 10 years. Once I got the dip switches right, it ...
