I know where you're coming from, Mike. Like you I
built my own K2 from the ground up starting in
1999 and "completing" it in 2003 with the KDSP2
(and some other adds updates in 2014); I still use
the K2 regularly even with a K3/P3/KPA500 etc. My
favorite time in the hobby was building QRP

If I recall it right, the schematics of the KX3 wasn't released
immediately after the radio, it took more than a year.

Mike,
I completely agree with your position. I suspect that Elecraft having
not yet published a schematic is simply a matter of time. Schematics for
most, if not all, of their products have been published, and the later
ones (K3 and later) are on their website as pdf files.

It's just a matter of principal, Phil. I've never in almost 49 years a ham
purchased HF gear that did not, at minimum, include the
I was writing software for radios in 1981. Diagrams might help understanding,
but the source code is the equivalent to a schematic. We already have a block
diagram for the KX3 and people keep complaining.

Source code is too low level to get a conceptual understanding of what the
software is doing -- a software architecture diagram is likely to be more
useful for that. (in a similar way, for hardware a schematic diagram abstracts
out implementation details such as PCB layout and track routing to
These days, the source code matters as much as the schematic. Want to find the
Weaver SSB demodulator? That is in software.

Mine works just fine, without schematics.

Hi John,

I had some trouble with the LT1965 regulator oscillating, probably due
to the lead inductance of the leaded (non-smt) capacitor I used,

Mine was from the Blue Mountains in NW Oregon in
1955. ARC-V gear powered via a dynamotor.
Those were NOT the good old days :-)

For me, portable operations went from a rare, scheduled event requiring a
team of people and equipment to a small Nikon camera bag that fits in a
corner of a bag on my motorcycle. In other words, it went from a chore to a
joy.

For what it's worth, here's my recent solution for bicycle portable

It weighs a bit more than Wayne's station, but I don't need trees to
hold the antenna up.
