ample.net... Do you remember the giant sunspots during the 1960's you could see with the naked eye? Solar flux over 200. I used to pick up WWV on 25 MHz on my cheap walkie-talkies. New Zealand used to blast in around midnight local time just below 18 MHz. Good times. I'm surprised you could hear 25MHz WWV on a cheap walkie talkie. Surely band conditions opened up that you'd get all the CBers first, so they'd wipe out WWV. The superregenerative receivers were wide band, but the CBers were a lot more plentiful. -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- In the 60's, there were relatively few CB'ers, and the ones that were around were legal 3 watt output. The big CB boom didn't happen until around 1971 or 72. WWV would have been what? About 50KW? At any rate, a lot more powerful than a 3W CB. |

These were cheap crystal controlled transmit walkie talkies. The receive as mentioned was wideband and in the late afternoon during peak solar conditions (late 60's) WWV would fade in and out. I don't know what path the signal took,or even what frequency I was hearing - I assume it was 25 MHz - but I could hear it pretty well from northeast Detroit, MI. Jim (MI) |

![]() As I remember, and don't take my memory to the bank, 11M came about 1958. I built a 5 crystal/channel Heath around 1960, I believe. Ch 9 was the call channel, this was before REACT came about. The only radios out there were a Halli, Courier, and Heath. Near as i recall, Allied came out with a rig around 1962. I remember taxi and some truck company's on ch23. It was a real mess. Hams were ****ed, but most I knew were in there with the rest of the noise. Lots of medical inside ch22A and B. Which became ch24 and 25 when they opened up to 40. As I said, 9 was call, 10 to 15 was to anyone, other channels were inter-ticket only. It was fun, but when it got busy, I walked away. Did make some nice local friends on it. Lafayette, and then Allied/Radio Shack really got it moving with reasonable priced radios. I still remember my Allied with tunable receive and a spot for TX/RX. I was a 20Q call. And that's about all I remember from back then. Or, I could be wrong on some of this info. Drifter... E.F. Johnson also made early CB radios. |
