I missed reading Vol. 72, issue 22 of the Elecraft Digest so got a chuckle with this one.....but
I am using a 2N2222 as an 18-dB buffer amp following my K3. This is on 500-KHz running the K3 in TEST mode where the output is ~ 1mw via the KXV3 option. I run 0.25 to 0.62 mw to drive the 2N2222 up to 10mw output. This then drives a converted Non-Directional Beacon (NDB) transmitter to 100w in CW/QRSS/PSK-31/WSPR (the legal modes for the ARRL Experimental Group on 600 meter band). The NDB originally had a xtal controlled oscillator using SSB+carrier for pseudo-AM MCW ID in morse code. A happy coincidence is that the drive requirement suited the K3 in TEST mode. The NDB pre-driver stage is also a 2N2222.
