Over the past few weeks Iβve had time to examine many dozens of diodes, mostly germanium, in my crystal radio diode collection. Many of them were removed from equipment built in the '50s and '60s (old diode matrix boards), some are vintage NIB 1N34As w...
Curious about what you can hear on shortwave ham radio? This video is a brief survey of the diverse world of communications on the shortwave spectrum. Expand your radio horizons and enhance your emergency communication preparedness by tuning in to the world of shortwave ham radio. If youβve started delving into radio communications beyond local [β¦]
Turning back time to virtually witness a critical historic method of shortwave communication using the fundamental mode of continuous wave modulation. This is a film from 1944, teaching the basics of Morse code, for military comms. What is the proper (and most efficient) technique for creating Morse code by hand, using a manual Morse code [β¦]

This is a video of the German Weather Broadcast from DWD, Hamburg, on shortwave (HF), using teletype (RTTY). I demonstrate two decoding software options: JWcomm32 (older), and, FLdigi. Note the in FLdigi, the βReverseβ feather is selected to properly decode the signal (in either USB or LSB, you still need to select, βReverseβ). The radio [β¦]
This video is an introduction to an international public-service and technology hobby known as βamateur radioβ (or βham radioβ). Amateur radio (also called ham radio) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term βamateurβ is used to [β¦]
Before modern radio broadcasting, the trails were being blazed both in public broadcast, but also critical links out of the local area. Hereβs a side-look back in timeβ¦. in this 1939 Film: New Zealand Shortwave Communications; Morse code (CW) The romance of the radiotelegraph service (in this video, the service in New Zealand) is a [β¦]
