I dunno how many times I worked "6L6GB". "QSL
via the buro". Yeah, right. ROTFLMAO! You probably did work someone who had a 6L6GB vacuum tube final in his transmitter....... :-) Others: 6u6gt 6w6gt 6w4gta 6y6ga 6k5gt 6k8gt 6j5gt 6a8gt 5z4gt 5x4ga 5r4gyb 5u4gb 3q5gt 2w3gt |

You probably did work someone who had a 6L6GB vacuum tube final in his transmitter....... :-) No doubt. But most of the serious 80M dxers in those days ran "suds", a lotta power, not just a lotta power but 'WAY too much power. Back then the max allowable power was one kW input vs. today's 1.5kW output. Any number of the Really Big Guns used homebrewed amps which tossed out a kilowatt's worth of heat alone. Or more. And those beasts weren't lossy linears either. Which is another example of blatent "impurity" in the CW bands. Offhand I'd be willing to bet that there are far fewer instances of busting the power limits today than there were back then. The FCC took the easy way out of having to bother with enforcing the power limits by roughly tripling the max allowable power input, clever labor-avoiding folk that they are. That move plus economics, the drying up of the WW2 parts sources and the need for linear amps have "solved" the excesss power problem and brought most of those bad old boys and their descendants into "compliance" today. Others: 6u6gt 6w6gt 6w4gta 6y6ga 6k5gt 6k8gt 6j5gt 6a8gt 5z4gt 5x4ga 5r4gyb 5u4gb 3q5gt 2w3gt "Tube callsigns" were a favorite but there were others and some were a tad on the raunchy side. 4Q2?? showed up more than once. Whatever it took to get some giggles. w3rv |

Have heard what is likely an urban legend of a ham (who was also a broadcast chief engineer) using the 50KW AM transmitter in his charge to work some rare DX on some HF ham band. Late at night when it was off for maintenance. Seems unlikely as the power amp would have circuits tuned for the MW AM broadcast station's frequency and low pass filters to block harmonics in the SW spectrum. That's not something one can modify in a few minutes. Oh, you could connect a ham transceiver to the broadcast antenna tower to work some 160m DX, but that would be legal. |

The late WB8LUA was chief engineer at WNOP, a Newport, Kentucky 1,000 watt daytimer with transmitters in suburban Cincinnati. They used a three tower critical array and all three towers were about 295 feet tall. Len would disconnect the feeders after sign-off and fire up on 160m through a Dentron tuner at the base of one tower. His barefoot sigs were incredible. Unfortunately for him, his TS-820's receiver was eaten alive by broadcast band overload. An old time W2 in New Jersey (still living) was nailed by the FCC for running 35 KW from his home in the early 1970's. He beat the rap on a technicality and is involved in "hi-fi" SSB audio on 20m in his dotage. Dave K8MN |
