I was WN8DVT-WA8DVT in Dayton in about 1960.  See picture of my first 
stations here:

The top picture shows my Hallicrafters Sky Champion (was an antique when I 
got it) and an Ameco AC-1 (AC-1 kit bought mail order from an ad in QST).

The next picture, after I got my General, shows on the far right a homebrew 
single tube 6146 amplifier, and a Heathkit VF1 VFO.  On top of the VF1 is a 
6AU6 push-pull modulator I built from plans in an old ARRL manual.  I used 
the modulator on the 6146's screen grid.  By setting the control grid bias 
just right, the screen modulation produced a double sideband signal (sort 
of)--I got good audio reports as such, anyway.  I couldn't afford to buy an 
output transformer to build a plate modulator to run AM.

As you can see, my station was in the attic.  The antenna was a 40 meter 
dipole which ran from one end of the attic to the other (just above my 
head), and then out through a hole to a tree in the front yard.
