[Boatanchors] Dx40 and VF1

[Rob Atkinson]

I'd just build a small power supply and run the VFO separately and not
worry about the iron in the rig.  Besides the reasons given, when you
power the VFO separately, you can fire up just the VFO and leave it on
during the course of a day's operating.  This allows it to settle down
so it doesn't drift very much.  Most of the 1950s VFOs take a few
hours to really reduce the drift down to less than 100 cps / hour.
When rigs have the VFO built in or run off the rig's supply the whole
show has to be fired up.   I prefer to just have the VFO on and only
run the transmitter when I need it.  All you need is a chassis, fuse
and holder, on off switch, power cord, small 120 to 400 to 600 VCT
secondary, 100 ma or more plus 6.3 v. secondary, pair of diodes,
filter choke, 20 mfd filter cap and 100 K bleeder, wire, binding
posts, rubber feet and output terminals.
