[INLINE] In the mid 70-ties the clubs organized meetings where new techniques were presented. One of such meetings took place in the spring of 1976. During that meeting Kazimierz SP3NK presented his new transistor TRX (bottom right-hand side of the picture): crystal-controlled transmitter with 5 transistors with 1 W power, superreactive receiver with 2 transistors, fed by a 12 V source (3 "flat" batteries).
Designed by Julian SP3PL, it was a technical "hit" in Poznan, built by almost every VHF amateur in the world.
