The multiPIG specifications
The preliminary specs are:
Receive from 100 KHz through 30 MHz.
Transmit on ALL HF bands through 10 meters; 11 meters CW too :-)
Variable 4.9152 MHz band pass filter
Radio "system" will utilize band modules like the TenTec Scout. MC145151P2 PLL
MAIN TUNE will double as a Signal Generator
using a LMC662 and a LT1252
FREQ DISPLAY will double as a Frequency Counter
This will be a very "MANUAL" radio INITIALLY
Frequency sub-bands are set with dip switches
Each sub-band is 10KHz to 30 KHz depending upon Main Band
using a J309 VXO Reference Oscillator
Main VCO using a J310 and
4-MV209 varactors tunes 2-30 MHz minimum
VCO used a VN0106/2N7000 AGC loop
Built-in K1EL memory keyer (K10 chip)
Built-in Capacitive Touch Paddles
5 watts out, fully adjustable
SWR indicator and BALANCED/UNBALANCED ANTENNA Tuner optional
Transmit function could be optional (Receive Only)
Completely modular, designed with the experimenter in mind

The Freq counter/display is from AADE
Ugly-Manhattan style construction throughout.
