Description: The "Half Pint" is a easy to build QRP transciever, built with just 7 transistors. I've had quite a bit of fun building and operating this little rig. I hope you will enjoy it as much as I have. It features a direct conversion receiver with an active audio filter. Specifications Power supply: 9-20 volts DC Receive current: 35 mA @ 13.8 VDC Power output: up to 1 Watt on the 40 meter band, 500 mW on 20 meters, with 16 VDC power supply Receiver sensitivity: approximately 10 uV @ 10 dB S/N Audio gain: 42 dB + 20dB from Q-Multiplier = 62 dB Receiver Selectivity: less than 500 HzKit Includes: 2.9" x 1.7" high quality double sided circuit board. Gold plated. Made in U.S.A.Quartz crystalMulti-turn trim pot to adjust filter Q.20 machine pin sockets to connect to off-board components.Molded inductors, so no coils to wind.
