Hi guys,
I once had an FT-101E and had no problems with TVI.
"Those 101's use the so-called " TV Sweep " tubes and are notorious for coming in on all of your neighbors TV's, stereos, phones ect...."
Sweep tubes (horizontal scan output) and many otherTV tubes were commonly used because they were dirt cheap, you could get them at any TV repair shop and could easily handle the high voltage and short duty cycle encountered in CW and SSB work. When operated within operational parameters they generated no more spurious emissions than any other tubes.
FYI, the common transmitting tube 807 was once used in early RCA B&W sets, later the 5 pin base was changed to octal and became the most common sweep tube of all, the 6BG6. Early on I noticed the internal structure was the same and used it in many RF experiments that called for an 807 because I had no source for it at the time. I only learned of it's history much later, strange I should pick up on that long after the fact. (;->)
One thing to note, the WWV 10MHz band switch position and crystal are of course very useful, I don't remember exactly but maybe it could be used today on 30M. One bit of caution, if the 11M crystal is in it's socket, TAKE IT OUT! Many of those rigs were used illegaly on CB with the yellow wire clipped but I won't go into that, just keep it legal. You don't want to end up like the latest guy the FCC pasted to the wall, he's not permitted to even own any CB gear for the next five years.
