This Heathkit thread has been very interesting to me as a

20 years ago, I had a Heathkit-style assembly procedure in mind. In

Don, you old f**t, I'm 32 already, 10 months older than thee.
Regarding surface mounts, I have used Scotch tape to pick up and place parts.
It holds nicely while tack soldering and is easy to reposition. I also like to
flood with solder and wick the excess, it's risky, but usually works
OK! OK! I should have phrased it that nearly no hams build anything,
anymore (one out of a hundred hams), and most hams are scared of
trying to do SMT (if they even know the term). Oh yes, hams build
antennas (those things out of wire) and connect radios to other
accessories and plug'em in

I disagree that Surface Mount Technology has taken kit building out of
the hands of most hams. Yes, it is not a task for the sloppy builder,
or for those who do not have good hand and small muscle control - you
must hold those small parts in the proper place while soldering, but

It's great to see general interest in kit building, but I'm waiting to see
if they are no solder kits. The old Heath had gone to no solder kit TVs
and computers
In the 1950s, the Heathkit AT-1 and AR-3 were pure junk. Yes, the prices
were low, but the design quality was awful. The DX-20, DX-35 and DX-40
were just okay but the VF-1 was trash. The DX-100 and DX-100B were okay if
you were rock bound, but if you used the VFO - it was a VF-1 - and it
was
The VF-1 could be considerably improved if operated from a separate
power supply and left on long enough to thermally stabilize. Not saying
it could be confused with a crystal controlled oscillator, but a lot of
its problems were related to voltage changes from the associated
transmitter.

I hope they will make test equipment kits again.
Some folks are still running their Heathkit radios too.
