Re: RF Spectrum Analyzer

Apparently some pilot thought he heard your station in their aircraft radio, and complained. Regulatory folks want measurements showing your station meets Canadian emission limits. You are dealing with bureaucrats. They deal with their pals--or at least their acquaintances. You are not in that crowd...

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.

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. So, whatever power coming out of the end of the coax is what you are radiating. You loose some power in the coaxial cable--so your effective radiated power is ...
