I once knew a Novice ham about 30 years ago who modified a Viking I to have an external power supply for the modulator, and 8417 modulator tubes. This thing could really modulate that 4D32. One lonely day the thing was put on 11 meters, and the 5R4's were removed so there was NO B+ or screen voltage to the final RF amp...that is until the modulator was driven. This produced a very distorted and effective jammer that occupied all 23 channels and then some. Another ham cam by who could play the harmonica. You could say this was DSB without carrier, and overdriven to the limit for maximum splatter effect. I forget the name of that troublemaker, but my good buddy W5OMR is using those same two 8417 tubes today in his Titanic speech amplifier.
