I have the MFJ-9040, 9030 and 9017 rigs. Using the 9040 rig with a variable
Voltage power supply, I can lower the output power all the way down from 5
Watts - down into the 100 milli-Watt range with no chirp at all, using an Oak
Hills Research QRPp Watt-meter. I have made numerous QSOs with it in the 100 -
150 mW power level.

I also have a Cub for 30 meters and worked a /MM off the Baja California coast
using a 9 Volt transistor radio battery for a power supply.

have my first 40 meter MFJ CW radio with the keyer and CW
