The Norcal keyer chips were used in the very popular keyer kits from
The Norcal keyer chips are fully pin compatible
with the PK-4 keyer.
The Norcal keyer chips are also pin compatible
with the PK-3, PK-2 and PK-Basic (Tick and K8 chips, too) with the addition of a 10k ohm pullup resistor
between pin 1 and 4 of the keyer chip socket. The Norcal keyer chip shares the same pot speed
control of the previous PK series.
Also note that there are two versions of the chip, the regular version and the Pacificon
version which adds a sidetone frequency set but which has a higher minimum speed. If no preference is
indicated at the time of purchase, the regular version will be sent.

your keyer chip customized with pre-programmed memories or different default settings and we'll
