Re: 87.7/87.9 Brighton

You can have images, difference frequencies, and RITOIE like interactions with the oscillator and its harmonics on some radios. It's kind of like when all the stars are in alignment on those, because the oscillator frequency varies. When I've heard just one program in an intermod image, the other is...

Re: 87.7/87.9 Brighton

What is RITOIE? I'm not familiar with that term. RITOIE stands for Receiver Induced Third Order Intermodulation Effects. The two strongest FMs in 48114 are on 89.7 and 91.7. 2 X A - B = 2 X 89.7 - 91.7 = 179.4 - 91.7 = 88.7 2 X B - A = 2 X 91.7 - 89.7 = 183.4 - 89.7 = 93.7 A and B are the frequenci...

Re: 87.7/87.9 Brighton

I think GM and Ford have had some kind of mutual licensing agreements for those types of performance issues. Since Delco invented most of them, including seek and scan, originally marketed as the "Wonder Bar" back around 1960, there is probably a net income to GM from the mutual licensing agreements...

Re: 87.7/87.9 Brighton

I stayed overnight in Brighton several weeks ago for a Continuing Education at Cleary in Howell. I noticed that there was a lot of RITOIE on the hotel room clock alarm radio, but none on the Buick GM Delco car radio. The strongest signals there are WUOM 91.7, WTAC 89.7, and WHMI 93.5, between V-Soft...

Re: 87.7/87.9 Brighton

Somebody is probably rebroadcasting the Internet feed of WKFM, er, whatever it is now. It really doesn't take much power to be heard in a small area like that. However, it technically violates Part 15 and is a pirate, if it can be heard more than 50 feet or so under ideal circumstances. They can get...

Re: WDFN nights

WWRL 1600 has been a perennial DX log in SE Michigan, off the back lobe of the four tower parallelogram, I think a rectangular arrangement. Kevin Sanderson told me that he would frequently hear WAAM on the off air monitor when they signed off the air back in the late 1970s, out at the "Lake Sinclair...

Re: WDFN nights

On an AM Radio group on Facebook, someone in western Massachusetts yesterday (4/20) reported hearing nighttime interference from WDFN to Bloomberg's NYC WBBR 1130, usually solid at his location. Much like listeners in metro Detroit, he had never heard WDFN before, much less at night, Someone forget...

Re: So many 50 kW AM signals

For a while, WOWO had an application to increase Night power to 15 kw Night. It would have favored Michigan. The WCHB/WMUZ 1200 50/15 DA-2 and the WLXX 1200 in Chicago complicated it.

Re: Source: Cumulus Detroit is for sale...

WJR has a better signal for all areas except close in in the major lobe of WWJ. It's the programming, but not just Right vs. Left. WJR's News could be a lot better. That would help their ratings a lot. Where I hang out, WJR has twice the Field Strength as WWJ. They used to be close to equal to WJR w...

Re: Source: Cumulus Detroit is for sale...

A big part of WLS's problem is its signal in the Northern half of the Market. In the really old days, 1930s to WW II and post WW II until 1960 when they went Top 40, the market to the South of Mokena/Tinley Park was a big part of their business. WVON 1450 was just 250 watts Night, WGRT/WJPC 950 was ...

Re: 99.3 WQAN Signal Strength

It's my belief that "conditions" are dragging the 99.3 signal inland on some days. There's no way it's broadcasting from anywhere near Traverse City. :blink Maybe they're broadcasting from a hot air balloon. Or from a pirate ship in Grand Traverse Bay? When broadcasting from a ship in Grand Travers...

Schematic Diagram For Realistic STA-111

Does anyone have any ideas for finding a schematic for a Realistic STA-111 Receiver? The relay system for preventing the amplifiers from being overloaded from shorts and other impedance mismatch overload is malfunctioning, and no one seems to know where to find them. I've talked to a former Radio Sh...

Re: Casey Kasem WJBK 1957

I'd have to look at the History Card. I think it was 10 kW Day and 1 kW Night on 1500 kHz. Before that, until 1956 as I recall, they were 250 watts Day and Night nondirectional on 1490 kHz from Highland Park.
