Re: Dr. Hook dies
The songs, both Sylvia's Mother and The Cover Of The Rolling Stone, were actually written by Shel Silverstein. Sylvia's Mother was VERY autobiographical, except Pandolfi didn't fit the lyrics, so it became Avery. I think it captures the true feelings of all three people in such a situation, though s...

Re: FM translator signal range in Metro Detroit
Thanks, Rich, for the analysis. There is flatter and downhill terrain to the ~150 degrees null South of the TL, so except for ground clutter and a 2 meter AGL Receiving Antenna Height, I would expect less loss, and probably little to no loss or very little at 20+ feet AGL.

Re: WSM 650
Can you get KBHR 580 K-Bear there since the "Upgrade"? :rollin I swear I think they got Chris Stevens character name from Kris Eric Stevens. One was from the 906 Area Code, the other from the 907 Area Code. Both Frozen Tundra. Ever hear of Peter Kott and Bernard Rosenberg there in Alaska? They went ...

Re: FM translator signal range in Metro Detroit
Yes. I was talking about M-59, US-23 and Davison Michigan. Thanks for the correction. And thanks to you for bringing these issues up. I learned some things too. Like they show M-59 turning north on the official MDOT Michigan Map and intersecting 23 Mile Rd., and Chris Bessert's Michigan Highways si...

Re: FM translator signal range in Metro Detroit
Using the F(50,50) graph, the 40 dBu contour goes out (40 dBu+38 dBk=78 dBu on the graph above). At 287.7 meters, that is about 11.7 km, or about 7.27 miles. The inverse field for the 40 dBu would be 2800 uV/m inverse field at 1 km/100 uV/m=28 km or 17.4 miles. That surprises even me, but I rechecke...

Re: FM translator signal range in Metro Detroit
It's been very recent that Longley Rice predictions have become more available. There is an old Rule Of Thumb that a clear unobstructed LOS gives you a 6 dB boost over F(50,50) curves in about the ~1.5 km to ~32 km range. And of course F(50,50) is based on about 30 foot AGL antennas, not the typical...

Re: FM translator signal range in Metro Detroit
I assume you mean US-23 NB, not 23 Mile Rd. (I'd have to look at the map to see if M-59 turns North and intersects 23 Mile Rd.. They should go back to calling 23 Mile Rd. Coldwater Road (Historical Name) or Avon Rd., extending it into Macomb County, as there would probably be less confusion with the...

Re: Old WDTR Tower gone
The tower that was taken down was 541 feet according to the VFR Aeronautical Map. The HAAT was 538 feet. Here is the WDTR/WRCJ History Card. They were originally proposed for the 42-50 MHz band but it looks like it was modified before it went on the air. There is a 140 foot HAAT facility shown at so...

Re: Radio.com playlists down.?
They're afraid that some Mom and Pop in the UP will steal their playlist and format. More likely the other way around. There are no secrets in radio. It's right out there over the air to be analyzed. If there was a decent format from a neighboring market you could hear OTA, they'd put a translator o...

Re: Old WDTR Tower gone
How tall are the remaining towers at the WRCJ site? Are they registered? I couldn't find them using the ASRN site. Only a short 135 foot pole. When they demolished Genesee Towers, the two old supporting towers of the WFDF Hammock antenna on top of the Mott Foundation Building, used as the Main anten...

Re: Travel Back In Time To Buy A Good TV Antenna
TV Antenna Sales are way up over the last few years due to price gouging cable companies. That's the unvarnished truth in my opinion.

Re: Rare catch on 720 AM at nightnslator
What time was it? WGCR Pisgah Forest, NC is 50 kW-D 15 kW-CH nondirectional. It has a translator. The Daytime AM translators cause a lot of confusion to board operators who don't understand AM radio, as the programming continues after the AM is supposed to sign off. So a lot of them occasionally for...
