1939 Film: New Zealand Shortwave Communications; Morse code (CW) 

8:13 power supplies: minor HT (2x 866), major HT (3-ph 6x 866 + standby) the latter faithfully reflecting the morse in a soft aqua glow

Thanks for the great historical video on CW! Such an important communication mode.

Wonderful old insight. I was a Radio Officer deep sea for over 25 years. Always enjoyed working the Kiwi stations, especially ZLB/Awaruaradiio. Managed to get probably my furthest QSO ever to him from just South of Land's End on 22mhz mid-morning my time. Things were a bit quiet for both of us, so we had a wee chat about rugby! They were most definitely good days, when 2 skilled communications experts could send/receive messages over great distances. Happy days, and 73's to all ex-Radio Officers both afloat and from the Coast Radio Stations.

The brought up a memory. In 1980 I contacted the radio station on the Queen Mary. The ship was in Long Beach California. The amateur radio station aboard was W6RO operated by the Associated Radio Amateurs of Long Beach Inc.

Very nostalgic as I worked at ZLW Wellington Radio in the late fiftes/early sixties and some of this gear was still there then.I loved this job.

I always keep at least one HF rig with CW key in good working order. Hey, after 2020 - ya never know.

Theres some die hard ham operators yet. Cw and tubes and tube radio art. Long live radio. Long live cw great film thanks. Tony ve4akf.

Thanks for this very interesting film. New Zealand, East Coast USA, Britain, France, etc. it is a fine documentary of marine SW CW radio circa 1939. A wonderful epoch, alas long gone...except on film or in personal memoires. 73

As he sits there comfortably reading his miraculous radio telegram he asks the passing purser: "I say"...excuse me sir, could you tell me what this means...Torpedo impact imminent !!!

how did you do it can you share with me , thank you

De DU9HLI 73 thank you for sharing.

Interesting video. What was the speed of the morse code messages? In India telegrams generally had a bad reputation - it was considered as harbinger of bad news.

Nice! Thanks!

Amateur Radio Operators often set up at county fairs and take radiograms to send. Try it if you see one. Its a novel thing these days but still works. Better yet become a Amateur. Easy and lots of fun. Great post. Awesome old equipment. Thanx.
