That was my first transmitter, too, Tom, a DX-35.  I operated on 40 and had 
a xtal whose tripple harmonic allowed me to work 15-meters Novice band then. 
I well remember that rig and the stupid 75 volts on the cathode-key circuit.

And, for Howard #3, the P2000CW was the accessible predecessor of the LDG 
talking wattmeter, except its output was in CW and considerably more 
accurate.
