Re: Broadcast Electronics Console Model 5S150

I have a PDF for the 100 and 200 series consoles, which includes the 5BES100. Don't know if this is the same vintage as yours, but you can PM me and I'll e-mail the PDF.

Re: STORQ Users--Downgrade coming

Apparently, if you get just the new I-pump you will still need a downstream automation system if you do other net programming. Don't forget that would include sports--like the Steelers net we carry.

Re: GR EAS-1/CAP-DEC-1 issues

Yesterday's weekly CAP test apparently failed when it was first sent around 11--some folks reporting strange error messages. Test was later resent around 2:00 Eastern, seemed OK that time.

Re: Convert to LEDs, or leave 110v?

Aha. You could stick an LED bulb in it, or cruise Jameco for deals on big LED's. The LED bulb would cost you oh $3 or $4, to get as much light from a couple of LED's--probably more. Plus time.

Re: Removed ye old Transmitter Monitor/Control

Pretty, but if you go to Pira.CZ, you can download a free program that will e-mail you when there is silence. Get an old computer & a cheap radio, plug it into the sound card.

Re: FM range question - coastal mountainous terrain

Another problem--get back up those ridges (some of the roads show on Google streetview)--and you have a nice view of the ocean, but no electric.

Re: FM range question - coastal mountainous terrain

Antennas: Those are circularly polarized antennas, dividing power between the horizontal and vertical plane. Two bays is usually unity gain.

Re: OMB PTX-20 test and repair help required

Ah--Gran Canaria. I see the problem! A losing battle with geography. (Think Oahu--the islands are about the same size.)
600 square mile island with a 6,000 foot mountain in the middle.
