What
features are in each new software version?
How can I get "the latest" software?
Original kits came with a controller IC "U2" programmed for v1 software.
Since then we’ve fixed bugs and added some new features, and now ship
kits with "newer software" programmed in the U2. In all instances, older
kits with v1 software will work well and as intended. If one wishes to
have the newer features, a purely optional and simple upgrade is
possible by ordering a new U2 controller chip containing the latest
software.
Features for v2 =
v1 features + Iambic Mode B Keyer + Frequency Presets
Features for v3 = v2 features + CW Speed Select via
rotary encoder + SK Mode with Presets
The single manual we have now
indicates all features present beyond the v1 baseline software, with
indications for the version in which they were added. So if a
feature is described in the manual but does not appear to operate as
described, then it is likely that your software is an older version.
Your Old Friend still works just fine! ... but it just doesn't have the
specific feature added in a later version of the software.
But the solution to all
this possible confusion is easy! We can ship you the U2
controller chip containing the latest software for just the cost
of the new chip and shipping fees. Merely send $8 via PayPal using
this link to purchasing the "Old
Friend U2 Controller".

Before you start assembling your kit ...
Using your
multimeter in the lowest "ohms" position, check the resistance between
the U1 regulator tab and its lower leg (toward the inside of the board)
to ensure that you do not read a 'short'. If you do read a low
resistance value (e.g., less than 2 ohms), please contact George (n2apb
at MidnightDesignSolutions dot com) to let him know before proceeding.

Nothing works after I plug in the U2 microcontroller
--
Is it oriented properly in the socket with the IC's pin 1 'dot' closest
to the display?
-
Display receptacle (2x8 pin) doesn't fit into PCB -- Yes
it does; the holes are slightly too small and it's just a 'hard fit'.
Press hard.
-
The 7/8" standoff (and 2 screws) for the end of the display are missing
-- Yes; not needed and not included.
-
Is it hard to screw in the 8 screws holding red PCB cover and OF PCB to
the 4 standoffs? -- Use a 1/6" jeweler's flat blade
screwdriver.
-
The Tune/Speed Pushbutton doesn't bring up "Presets"
--
Don't forget to ground the other switch contact next to the one with the
wire you added.
-
The Tune/Speed Pushbutton doesn't 'click when depressed
-- Be sure to leave enough room for this to happen when you attach the
knob.
-
My connectors are not aligned in enclosure pre-cut holes!
-- Loosen the 4 top nylon cover plate screws to 'optimize' dimensioning
of the PCB assembly beneath it.
