What I found interesting was the pattern on the (Tek?) scope above the rig.....must have an incredibly slow sweep setting and very long CRT persistance to display 'CQ' in pulses from the key like that! :o0 73, Leo |
Check out the man on the cover of QST March 2004 smoking a Morse Code bong! The use of breath power to key a rig goes back at least 32 years that I am aware of. There were patients of mine who used that system to play pinball machines ...for flipper control. I also recall having a QSO a number of years ago with a fellow who used a puff keying system. I haven't read the article yet to see if there was a new "twist"..... also had patients who used the system for scooter control .... tried it once ...took out some woodwork and plaster.

At 30 wpm, the displayed code requires a sweep time of about 1.2 sec 73 de Jim, N2EY |

I didn't read the article yet, but that seems pretty fast. - Mike KB3EIA - |

At 30 wpm, the displayed code requires a sweep time of about 1.2 sec Agreed - but at a sweep of 1.2 seconds, the phosphor would need to have a pretty long persistance to make a nice even display like the one pictured.......bright, too! My Tek 465 can't do that - where can I buy one of those? :) 73 de Jim, N2EY Can a person even do 30 wpm with one of those? I didn't read the article yet, but that seems pretty fast. The article claims 25 wpm or more from this device. Maintenance isn't mentioned, though - one shudders to think what that thing would be like after a couple of weeks of use! Ewwww. - Mike KB3EIA - 73, Leo |

My Tek 465 can't do that - where can I buy one of those? :) Tek makes lots of DSOs now. They can do so without straining. Do you need a Tucker Electronics catalog? Tucker used to sell ham equipment until business in that line got way too unprofitable (apparently all Texas hams get Southgate Type 7s or Elecraft or something). Morse code can do anything. Slowly, to be sure. Morse code gets through when everything else will. LHA / WMD |
