This is a vertical plug-in module providing one multiplier stage followed by two stages of
amplification.
A harmonic of the oscillator output is selected at the multiplier stage TR1 and after two stages
of amplification TR2 and TR3, the signal, now at carrier frequency, is fed to the PA Module (11).
All stages are capacitively coupled and inductively tuned. Test points, TP1, and TP2, are
provided in the emitters of TR1 and TR2 respectively.
