Re: WPON testing again ?

Kind of related, as they are on the same towers: This afternoon, I heard what surely must have been WCXI 1160 fairly strong in Mexicantown, not booming, but easy to hear. Two old men talking about 1950s cars and 1950s music. They also sounded like they were overmodulated. Also heard Motown music on...

Re: WPON testing again ?

Hawaii has many shared AMBC antennas, for several stations in some cases, all the AM stations in Honolulu are single tower. You find this where real estate is really pricey !

Re: Is ≤2dB a good noise figure for an amp or should I get one that has less noise?

Is the 3 DB an ANTENNA GAIN figure ??
Depends what freq range you are on and what is the signal that you are listening for ??

Re: Indespensible SW resource - HF Underground

My favorite source of HF BC info is gone. "What's on ShortWave right now" where You could type a freq and it would return a list of users and what one is currently on the air and some rough strengths of the signals you would likely hear AND the program language !!. Made it easy to be sure what forie...

Re: CHYR Radio 7 Canada

I started listening to CHYR (CJSP in Canada's Sun Parlour) when I was about 13 years old. I thught it was strange for them to have to change frequency to keep broadcasting at night. Now we had WNZK that changed from 680 to 690 at sundown ! I got a Hallicrafters S 38 D for Xmas in 1957 and listened t...

Re: A great explanation of "Tropo"

Have been working some good distances on tropo openings, since I got on VHF back in 1962, on the 6 M band and in 1978 on the 2 M band.
Started listening to FMBC DX with a 3 tube Granco tuner and a twinlead dipole taped to my wall, in 1960 :D

Re: Reduced ERP from "Overheight" FM Stations

Not happy with 300 ft and 3000 W ? :D
Was that on 100.9 ? I see 3000 W and 328 ft HAAT listed !!
Was the station licensed to Allegan or just located there ?

Re: As the repack continues, TVFool still doesn't have an updated transmitter database. What's going to happen?

I have not been too interested in TV but FM Fool has been pretty accurate. I use it to make a list, when we go camping around the state , to predict what I will likely hear out in the woods.

Re: Reduced ERP from "Overheight" FM Stations

Back in the late 60's I got all the FCC signal level curves and charts for Low antenna high power vs. High towers and low power. I wanted to see what reception would be at different distances and see if there was really parity . I found that he low power and high antenna signal went a lot longer dis...

Re: More New Outdoor Antenna Options, And The TV Antenna With Red Light

Those non, directional saucers are subject to multipath , a problem in urban and suburban settings. Used to cause "ghosting" in the old signals but now it will cause intermittant "pixelating" or blue screen. Some directionality is the cure for that problem !

Re: Why Are Towers Shrouded On Satellite View?

I see lots of towers on GoogleEarth. I am particularly interested in directional AM BC arrays. Some images are so clear the guy lines show up, some are not so good and you have to look for shadows to pinpoint towers. I have caught details like FM arrays on the side of AM towers.
