Prototype 2N2
The NorCal 2N2/XX series of transceivers are real, PN2222 based, QRP
transceivers, available on 20, 30, or 40 meters. They are based on prior
K8IQY 2N2 designs – using a "best practices" approach.
This version of the design employs a PCB for building ease and predictable,
consistent performance. Each kit comes complete with all parts, a painted and
silkscreened case, and detailed assembly manual.
The all analog design results in very low noise, affording a sensitivity of
0.2 uV, or better, depending on the band. This rig features 6 poles of crystal
filtering, a stable VFO with 100 KHz band coverage, (50 KHz on 30M), world
class QSK keying, built in sidetone, and room filling audio.
A commercial quality PC Board is used, featuring thru hole construction with
leaded parts, except the mixers which are large footprint SMT, commercial
grade, level 7 devices.
The output transistor is rugged, self-insulating, and sufficient for 5-watts
of output power, adjustable down to the milliwatt level.
