Tells if unknown bipolar or FET transistor is AF, RF, or VHF and whether it is NPN or PNP. Transistor to be tested is placed in frequency-switchable oscillator circuit, and amplitude of oscillation is noted on meter. Highest oscillation frequency corresponds to highest amplification frequency. Six switch positions cover frequency range of 1 to 190 MHz.-F. Brown, An R.F. Transistor Testor, CQ, April 1975, p 35-36 and 66.
