[ARC5] [MRCA] CW Keying Wheel

[howard holden]

WNU was a coastal station in Slidell, Louisiana. They would have been on 22431, not 21431, which is in the 15 meter ham band. Plus, they would have been on 500Kc, plus a traffic alternate to 500 somewhere between 400 and 500 Kc, plus on 4, 6, 8, 12, and 16Mc marine bands. That wheel was probably an idle traffic wheel, which would have gone something like this: VVV VVV VVV CW DE WNU WNU WNU OBS? TFC 4/6/8/12/16/22 MC and would repeat. There's a photo of WNU on this site: https://www.radiomarine.org/historic-coast-stations

Not sure I was able to send previously.

I found WNU 36 at coastalradio.org.uk . It seems to have been a commercial telegraph station in Slidell, LA operating on 21431 kHz. My guess is the disc is a mechanical station ID disc.
