Re: [IRCA] [NRC-AM] Help please from Salem and Vancouver tower historians

[Earl Higgins <earlthenut@xxxxxxxxx>]

Steve (and others),

You will definitely want to acquaint yourself with David Gleason's excellent website at http://www.americanradiohistory.com/ ;. It contains Broadcasting Yearbooks going back to 1935.

Of course, as you correctly point out, BY doesn't seem to have started including transmitter coordinates until 1991. KSLM's location is given in that issue as 44 56 32 N 123 04 17 W (what you would type into Google maps: 44.9422, -123.0714); this is several miles south of the current FCC listing of 44°  59' 43.00" N 123° 04' 15.00" W (what you would type into Google maps: 44.9953, -123.0708).

If you look on Google maps, the "old" (1991) coordinates map to an address on a street curiously named "Tower Drive NW" but clearly now a residential subdivision. In fact, it is within 2/10 of a mile of the address you have for the tower site in the 1950s. It's likely the 1950s site you have, and the 1991 site Broadcasting Yearbook has, are in fact the same site. So there you have reasonably definitive evidence that it was probably there in 1976. Incidentally, you can see their now single tower located in the corner of some kind of orchard or farm by typing in the current coordinates.

Now, on to CKWX. The 2002-2003 Edition of Broadcasting Yearbook, the most recent one available on the site, lists CKWX 49 09 22 N 123 04 00 W (what you would type into Google maps: 49.1561, -123.0667). Looking at Google maps satellite view, you can see there are indeed 2 towers at this site, and both http://www.radio-locator.com/ and http://topazdesigns.com/ambc/ agree that this is the current site of CKWX. So we can assume that it was there in 2005 as well.

So one could say, with a pretty high degree of confidence, that KSLM, at -123.0714 degrees west, being further west than CKWX's -123.0667 degrees west, is your furthest west catch.

Hope this information is useful.

Sincerely,

With the discussions about transmitter locations today, I thought this would be a good time to ask a favor of you tower experts.

I'm not sure what my westernmost catch is.

In April 1976, I heard code from a DX test from KSLM-1390 in Salem, Oregon.  

In February 2005 I heard CKWX-1130 in Vancouver, British Columbia on an unattended overnite recording.  

The longitude of Salem and the longitude of Vancouver are so similar that one or the other can be shown as "more west", depending on what atlas or website you're consulting.  So the coordinates of each station's transmitter sites would have to be known in order to know who's farther west.

KSLM would still be farther west, according to where the towers are today.  But I would appreciate knowing where their stick was in April 1976, there being no source I'm aware of that can give you old-time transmitter coordinates.  Broadcasting Yearbook would eventually provide them, but had not yet begun to in '76.  Google sez their tower was on a hill in West Salem in the 1950's, and that the address was 520 West Hills Way NW.  Google Maps shows that address today with a suburban home and not a tower in sight.

So my questions are: Where was KSLM in 1976, and are CKWX's towers still where they were in 2005?

Thanks to all who can help!
