How do you calibrate
the frequency on uBit?
I have not figured out
the menu yet!
I do get WWV now on
about 15' of wire out the door.? I can Zero beat it and get
the AM at 9.8 something?

I found the same thing with a straight key, decent performance
with a paddle. Yes, the pops going into transmit are a bit
annoying. Perhaps a simple transistor switch to break the audio
connection could be a mod to pursue - the KK7B R1 and R2
circuits used a 2N7000 transistor for this. A little research
into the cause will probably find a cure.
Pretty amazed with it as it is - haywired it on the table and
it's working pretty well. Operation is intuitive. However, I
can't get the CW tone to change - hitting PTT doesn't seem to
set it as the screen says. So I can't move that yet.

Definitely a loud
POP in both the headphones or a speaker if plugged in.? It is
very annoying and occurs on both the PTT keying transition and
on the first dot of the CW keying transition.? Also, the paddles
are very difficult to send CW with as the keyer chops the first
dot and the timing is NOT consistent between the dot and dash
transitions in the keyer.? I've been a mostly CW operator for
over 50 years and this rig will not meet my specs as a CW rig
until that is fixed.? Also the hand key doesn't always key right
either.? I polished the paddle contacts and the hand key
contacts til they were squeaky clean.? They work perfectly with
my Elecraft K3S giving no errors (that I don't make myself) in
keying so they should do well with this rig too, but they
don't.? The hand key occasionally will trigger the keyer into
dots or dashes when first pressed.?
I did put the 4.7K pull up resistor right on the Raduino rather
than on the key jack but that shouldn't affect the voltage
divider operation if the software is working like is should. I
actually added a separate paddle jack because I do not want to
modify my Begali paddles by putting resistors in line.? That
would lock them to just the uBITX and I'd be unable to use them
with any other rig.

PS:? my uBITX made it's first QSO this morning on 40 meter SSB.?
7200KHz from KS to Tennessee on a very low mounted end fed Zepp
antenna.? Signal report was 4-4 in QSB but we completed the
QSO.? Hoping I can make a CW QSO now, but it's going to be
tricky with the keying malfunctioning.? (I did check all wiring
and it's good).?
