Re: VHF DX From A Mist From The Smoke Of A Distant Fire

Can you even imagine all the cell towers that are literally melting in these fires. No cell or data service for months. Kind of makes you long for having a landline again. And 2 meter walkie talkies. I'd say CB, but there always seems to be skip to interfere with anything further than a mile or so,...

VHF DX From A Mist From The Smoke Of A Distant Fire

Any predictions about the effect of the smoke from the forest fires out West on VHF DX? In the past, volcanoes and fires have had an effect. The smoke particles alone may have an effect, and water condensation on the smoke particles probably enhance that signal reflection. It seems like I heard FM s...

The rechargeable in mine no longer charges, nor can I figure out how to remove it without breaking it.

Re: Late Summer NOAA WX Station DX

I'd say that's DX. Often happens across the Great Lakes this time of year. Does your WX Receiver get the Marine Weather frequencies? Yes. It's a Uniden hand held scanner. Have you ever changed the rechargeable battery in that? I have a Uniden. I tried to get the battery out to replace it, so I woul...

The Climbing Of Island View Hill

Last week, I decided to take a ride along the M-119 Tunnel Of Trees. I had always wanted to see where the short lived WMBN-FM 96.3 site (mid-1980s) was, and if there was any evidence of there ever being a tower there. There had been a 683 foot tower there for a couple of years, which was reportedly ...

Re: Happy 100th Birthday 8MK / WBL / WWJ

Michigan now even has an NCE-FM station with K calls. It's KDTI Rochester Hills, on 90.3 with 37 watts. It airs Air-1. The tower is in Rochester, 1.5 miles NW of Yates, just west of the Bloomer Recreational Park. It's near South Street, "where all the hippies meet".

Re: Happy 100th Birthday 8MK / WBL / WWJ

WABC and WBZ. But time signal station WWV operated in the AM BC band in 1919 on 600 kHz before moving to Shortwave, even before KDKA. WWV even broadcast music at times in their early History. History can be complicated.

Re: Happy 100th Birthday 8MK / WBL / WWJ

There are many other stations who had experimental licenses. Many of these were at Physics and Engineering Departments at various colleges, including MAC/MSU, the station later licensed as WKAR. In terms of commercial licenses issued, it was about 4th, behind KDKA, WABC, and WBZ. KDKA was experiment...

Re: Did WKHQ or WKPK Ever Have A Published Record Survey?

Did they just use Billboard, Cash Box, Record World, etc., or did they have a typed/written in house survey? Usually they had those, if only for intro times for "hitting the post". I probably would have been good at that. Once I was at a seminar where the speaker asked a few of us to walk around the...

Re: antenna lift

Due to the dearth of FM Top 40 except WKFR Battle Creek (and AM at Night besides WKMI, and except for WLS and WOWO) choices in Kalamazoo in the late 1970s, WGRD-FM did very well in Kalamazoo back then, even with a relatively weaker signal. It was very tightly formatted. FMs from adjacent markets did...

Re: antenna lift

BTW, the departure from perfect circularity of the h-plane radiation pattern of a batwing/supertunstile TV transmit antenna is a lot less than that of a typical "circularly polarized" FM broadcast antenna mounted on the leg or face of a supporting tower structure. That certainly reminds me of the v...

Re: WMT 600 Cedar Rapids Legendary Self Supporting Tower Collapses In A Storm

And your point is? Internet radio is radio. But not nearly as reliable in my experience. Cuts out all the time, every day, if it works at all. It's a near daily frustration with me. I'd rather just turn on an old school radio. Some things about old landline phones. They nearly always worked 99 plus...

Re: WMT 600 Cedar Rapids Legendary Self Supporting Tower Collapses In A Storm

Time to sell the land, it’s worth more than the tower and the station together. Unless the FCC were to approve a brand new 100 kW/2000 foot HAAT FM facility for them to move to, it would be impossible to even come close to duplicating the eight state 0.1 mV/m coverage on 600 kHz. https://radio-loca...
