Night of nights, 2015

Every year, the Maritime Radio Historical Society celebrates the closing of the last commercial Morse code radio station, which happened at 0001 UTC, July 13, 1999.  They do this by re-manning the watch for a few hours in honor of all those who so diligently listened for distress signals on 500 KHz and other frequencies continuously for over 90 years.  Your humble author was one of those, who in the late 1980’s and early 1990’s strained to hear, through the static crashes and OTHR, the simple, yet effective combination of SOS sent in Morse code.

Fortunately, after the closure of KPH, the National Parks Service took over the land and preserved the buildings and antenna fields intact.  Today, a dedicated group of volunteers maintain these facilities as a working museum.  This is the earliest history of radio technology and from this, sprang Amateur Radio, then Broadcast Radio services.

So, if you have the opportunity on July 12 (Sunday, starting at 8 pm, EDT), tune around to some of the frequencies listed below and see how ship to shore communications was handled:

KPH KFS KSM WLO KLB NMC NMW Ship transmit
426 426 488 472 448 425, 454, 468,480,512
500 500 500 500 500 500
2055.5
4247 4343 4184
6477.5 6383 6276
8642 8438.3 8658 8582.5 8574 8368
12808.5 12695.5 12993 12992 12552
17016.8 17026 16914 16968.5 17220.5 16736
22477 22280.5

These are duplex frequencies, meaning; the ship transmits on one frequency and listens on to the shore station on another and vice versa.

Those medium frequencies do not carry that far during daylight, however the high frequencies should be heard across the world.

In addition to that, there are youtube videos to watch:

There are more videos on youtube, if one is so inclined.

Those old RCA transmitter look like they are in excellent condition. Somebody has spent a lot of time restoring those units.

Hopefully, one of these years, I will get a chance to head out to San Fransisco during the middle of July and see this in person. It would be nice for my children to see what their old man used to do in what seems like a different lifetime.

The old school marketing campaign

I found these old drawings in the filing cabinet and thought they were kind of cool. They look like they were drawn sometime in the 50’s for the WPTR studio at 1860 Central Avenue in the Town of Colonie.

It looks like there was a lot of Neon, including a speller, which I take to mean the sign would spell “W-P-T-R 1540” then turn off again.

This was the sign for the entrance to the studio building

I think this is a take off on the old KHJ sign in Los Angeles.

The General Electric BY-4-C FM broadcast antenna

Whilst working in the generator room at WFLY, I found this bit of treasure stashed on an overhead shelf:

General Electric BY-4-C FM broadcast antenna, ca 1948
General Electric BY-4-C FM circular broadcast antenna, ca 1948

That is a very old FM broadcast antenna from 1947-48.  It must have been intended as a spare antenna in case the main antenna had a problem.  It was never needed, so it remains in its original shipping crate.  I would think that these were rather well made, since the original main antenna was in service from 1948 until 1970 or so, when it was replaced with a Shively 6710.

The entire antenna is intact including the interbay lines, power divider T’s and tuning section.  Of course, it is of little use to the radio station today, as it is horizontally polarized.  Perhaps some museum somewhere?  I don’t know, it would be kind of neat to put it all together and use it as an exhibit.
