the joy of oscillation!
FT-243 crystal, one old classic...
little pearl have been used in each of our Michigan Mighty Mites transmitters.
There is not complete agreement on what constitutes QRP power. While most QRP
enthusiasts agree that for CW; AM; FM; and data modes, the transmitter output
power should be 5 watts (or less), the maximum output power for SSB (single
sideband) is not always agreed upon. Some believe that the power should be no
more than 10 watts peak envelope power (PEP), while others strongly hold that
the power limit should be 5 watts. QRPers are known to use even less than five
watts, sometimes operating with as little as 100 milliwatts or even less.
Extremely low power,1 watt and below, is often referred to by hobbyists as QRPP.
