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.
Customize your Norcal keyer chip: please indicate at the time of purchase that you'd like
your keyer chip customized with pre-programmed memories or different default settings and we'll
set that up at no extra charge! For example, you may want iambic mode A as the default OR
have the pot speed control as the default, it's up to you !
Here are a few of the Norcal Keyer chip features:
