[Boatanchors] FT-101

[Dave Mayfield]

Barrie, in my early ham days I ran lots of RTTY with a FT-101E, and 
after many hours the tubes did go soft, whet from 100 watts out down to 
about 60. So my thought is this, they can handle CW key down for some 
time. By the way how can you own a Bird watt meter and not have a good 
dummy load? A light bulb?
