Convert to LEDs, or leave 110v?
I'm thinking of replacing the 110v bulb with some LED's.

Removed ye old Transmitter Monitor/Control
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.

Anyone want to come and realign our STL?
At the radio shack...
We are just 2 hours east of Dallas.
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.

Will this STL link work?
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?

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

EAS911 Unit, trying to understand relay closures
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.

Re: Asking for any and all info on this unit please
Another pic https://www.dropbox.com/s/ids9h1nfee99lhc/reg1.jpg?dl=0 Once I turned it on, it makes clicks, etc, and the voltage moves slightly back and forth with changing loads. 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...

Re: indicators will go LOW (0 volts dc) ?
http://pdf.datasheetcatalog.com/datashe ... 828_DS.pdf
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?

Re: indicators will go LOW (0 volts dc) ?
[ 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?

indicators will go LOW (0 volts dc) ?
[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?
