Mouse Poop reduces eddy currents

12v relay activated when silence alarm goes off

Sits on top of the main rack.

I'm thinking of replacing the 110v bulb with some LED's.

One of the last pieces of 'home brew' equipment from the AM Side. We think that station founder made this and used it on this AM station since around the 50's.

During my short time here, all it did was serve as a silence detector.

At the radio shack... I'll buy ya a coke if you come climb the transmitter tower and move our receiver antenna to link up our recently relocated studio...

We are just 2 hours east of Dallas.

Removed from service years ago. AM Station.

Completely out of my league here.. We are moving an existing Nicom 9XX STL link.

This is a plot of the new proposed location. Anyone want to hazard a guess if it will work?

There are 2 DPDT relays inside..... EAS control. Thanks for playing

Taken at a nearby radio station. Going to be my responsibility soon.

I have been tasked with revamping the EAS relays.

We have an EAS911 unit.

I cant figure out why there are 2 wires, one carrying 36vdc from the transformer, and one that is grounded.

Looks like nothing is connected to LINE C, and Line A seems broken as all it does is click, and no voltage change is regis...

So one chip could control up to 8 lights? I could use existing 28v dc power supply, and all the old 28PSB Miniature Incandescent Lamps/Bulbs indicators?

[ The remote indication functions: 1) require current limiting resistors and 2) provide up to 100 mA
for indicators. A +5 volt supply is provided on the ECU rear-panel for remote control
operations. The remote control connections are located on the rear-panel of the ECU. ]


Sound right?

[The power level status indicators will go LOW (0 volts dc) when activated. ]

Does this mean that once the 1000w transmitter is set to 1000w, then the 1000w indicator circuit will no longer produce +5v?
