Any word on the length of the pending NPT?

I am trying to get all of the ducks in a row for the upcoming National Periodic Test and, since we know when it is scheduled, I was going to give traffic a heads up to adjust the break to make time for it. Has anyone heard anything about how long the script is or what the total time of the test will...

Re: Good ole analog

Assuming you would be using a quality manufacturer for the gear the 950 digital stuff is pretty bullet proof. I run a couple of Mosely SL9003Q radios and a couple of Harris HD Link systems and both have been trouble free. For backup audio and for data transport I have unlicensed Radwin data links wi...

Re: Setting ideas for an Optimod 9100a

I am fairly sure the station could save a lot of money by using a more modern STL method. Check the price for a dry pair. There are mountains of Tellabs equalizers floating around. I have at least a dozen that have been abandoned at various transmitter sites and I would be happy to mail you one alo...

Re: Electro Impulse Reject Load Schematic

Just for closure on this thread for future reference. I never did score any schematics but I have a Electro Impulse 50 kW dummy load that has the same auto on circuit at one of the other sites. I scabbed the parts out of the dummy load for the reject load since the dummy load isn't mission critical ...

Re: Broadcast Electronics MVDS, FM20B

The fan at the back of the controller has a habit of getting dirty and seizing up which takes out the power supply fuse to the whole controller. That is whether or not it has the MVDS option. I've had the BEs both with the MVDS and without it and the MVDS option really has limited utility. It had a ...

Re: Electro Impulse Reject Load Schematic

Good ideas, I also have two FMD-50ks (twin Harris FM 25ks) in the same cluster and they have the same reject load except I think they both originally came with a pair of oil cooled Bird loads that had a nasty habit of blowing the fan fuses and they burned up on both rigs. Calling Gates is of limited...

Electro Impulse Reject Load Schematic

Greetings, I was wondering if anyone can lay their hands on the schematics and parts list for an Electro Impulse DPTC-25KFM that is set up as a reject load? Although Electro Impulse is out of the dummy load business they sent me a schematic for the load but it is set up as a dummy load rather than a...
