[OT] A question for Elecraft

[Byron Servies]

Dear Elecraft,

Knowing what you know after designing the K3, KPA500, and KX3, what
would a through-hole kit design, along the lines of the K2, look like?
 I mean, you've learned a lot.  Surely improvements can be made?

You know, for those of us who know the K-Line is superior, but prefer
the Grey-Line anyway.

The problem, in a nutshell, is that through-hole components are becoming
increasingly hard to find.   It is for that reason that I am presently
looking for, and purchasing, through-hole components in bulk  for that
soon to come day when they are effectively no more.    Fortunately,  
they are  cheap right now, if you are careful what you buy.  For
example. 2N3904 transistors are about 2.5 cents each if you buy them a
thousand at a time.  (thats $25 per 1000). and 1N4007 diodes are 1.5
cents each in similar quantities.  I have my own list of about 10
different parts that will answer something like  90% of all ham radio
and experimenter type applications.


What I am looking for is a source of small PCBs that can be used to
adapt some of the surface-mount parts to through-hole circuitry.   Does
anyone know of a source for such a thing?   For example,. where I can
mount a SOT-4 type package on the PCB,. and then extend wire leads from
the PCB to a conventional circuit.  This would re-open the world of
dual-gate MOSFET parts that have disappeared altogether in through-hole
form, but are available in quantity as surface-mount parts. .  (example:
the 40673 dual-gate MOSFET that was popular in so many older designs)


Just my 2 cents worth

Hello Jim,

Unfortunately I do not know offhand of a source of small PCBs which would
suit your need, but some years ago when fiddling with my K2/100 and adding
some surface-mount devices, I wound up having to make some small "daughter
boards".

The type of PCB from which I cut these small boards goes by the name of
Oktopad, and is stocked by Farnel.  Other suppliers might also carry stock,
but I have not been able to check.  It is a predrilled fibreglass board with
copper pads on one side.  One type has a copper "honeycomb" ground plane on
the other side, another type does not have the groundplane.
