First amateur ssb

Above the critical angle, waves escape in free space while waves emitted under a low incidence angle can reach DX stations. John Glenn's audio files. Block diagram, schematic, and, photos of a typical TRF radio. In a superheterodyne receiver the desired RF signal is multiplied down to an intermediate frequency IF by use of a mixer and a variable frequency oscillator VFO or Local Oscillator where there exists a multi-stage filter to select the signal to pass onto an envelope detector.

After having reduced the dynamic range of the signal, a servo system, the automatic level control, ALC is used to set the gain properly so the power amplifier is used all the way up to its maximum capacity, but not above. Participation is limited to club members residing and operating within a mile radius circle from the center of club area except for expeditions organized specifically for the contest conducted by members who reside within the club circle.

A lot of cables to connect!
