John and Jerry:

I just checked the kit page on the 4SQRP website and the "builder's
alert" clearly states that if it sends V2 at startup, it is one of
the early chips that had been incorrectly programmed. However, it
also states that it may still function, but not as stably as the
corrected chip, so Jerry probably has a functional device, only not
as good as it would be with the corrected software.
You are right that contacting Steve, KD1JV, might be the best way to
get the updated chip, if it is still available. Or, as Jerry
suggests, if Steve doesn't mind, he could send Jerry the code so he
could reprogram it himself. He may not wish to do that if the code
is "proprietary" to someone.

V2 would’t be the battery voltage by chance ?
Chapter Two: One step forward and one
The PIC wasn't to blame for the silence.
I put a scope on the output from the 74HC00 (pin 3) to
the speaker. Pressing and holding the program button
produced a stream of
raggedy but lovely square waves
(amplitude ~2-3Vpp). Clearly the PIC was sending Morse
as it was supposed to.
The problem had to be a faulty speaker.
I removed it and temporarily put an LED in its place. It
clearly flashed Morse. Then I connected a different
speaker. It worked fine, and I thought I had the
But no. On power up, the chip sends
"V2". Oops, that's not the right ID. According to a
note that came with the kit, it indicates the PIC was
one of an early batch that were
So I'm back where I started, still
needing a correctly programmed PIC, or alternatively,
Thanks for reading.
