I had an HW-16 when a teen novice, and bought a Heathkit VFO to expand it. Used it one summer and put it all away. My dad sold the VFO off, and the buyer smoked it...power cable was configured for HW-16 only! What was the OTHER rig you could wire it for, and, can one rewire the VFO (model #?) to serve the other? (A matter of an 8 pin plug, as I recall.) HELP please!

I bought an HG-10 VFO for my HW-16 in 1969. My recollection is that it was used on xmit only, and the
built in vfo on the transceiver was used on receive. I
believe the HG-10 was the only external vfo available at
that time.

I think the VF-1 could also work with the HW-16.  Good like finding one of those, there as unobtanium as the HG-10.  I also have an HW-16 I acquired recently and I discovered references to a mod on the web that allowed you to use the rig's VFO for transmit as well as receive.  You replace the crystal oscillator tube with a mixer tube of some kind, and inject the VFO in at that point.  Not sure how much work you're willing to put into an HW-16 but I thought this would be the best way to go, as it would give you about the best it would get with one of these rigs. I still have half a dozen FT-243 xtals I used back in the day, so I might stick with those for a while, until I get motivated to dig into it.

The other Heathkit rig of that vintage would be the DX-60 transmitter.
The plug would carry the power (high voltage and filament), and
possibly 117VAC for switching.  Mis-wiring the plug could blow the
filaments in the tubes, and perhaps some capacitors if they weren't
rated for a high enough voltage.  You would have to check the transmitter
schematic, but rewiring shouldn't be difficult.
