Bill,
Sorry that you missed my point - those changes, while significant, did
not change the block diagram - they did produce modifications of the
circuits within the blocks, but the transmit and receive chain were
unaltered.
Even these changes, while significant, did not result in extreme rework
of the K2 - of course, your concept of extreme rework may differ from
mine, but I relate to extreme changes as a *major* rework of the circuit
area rather than a minor change or addition of components.
I might point out that I have worked with large computer cards that have
had layers of change wiring that one had difficulty getting a 'scope
probe onto the pins of the card - that to me is major rework - the K2
rework changes are minor with that perspective.
73,
Don W3FPR

If the K2 stability can be any example, remember that the K2 did not
have significant hardware changes to the receiver or transmitter chains.
No? The 2nd XFIL mod, the BFO stability, PLL temperature compensation,
the KPA100 mods, the PLL stability mods all seem significant to me.
