TS570 S-Meter & Info

TS570 S-meter vs RF Input



TS570 Intermittent fault


SSB/CW RX Audio: reduced output level with distortion


Failed joint at pin1 CP500 [1.1MHz o/p] disrupting the 8.8MHz 1Vpp carrier injection level [noisy 200mVpp]


The 1.1MHz squarewave is filtered & fed to IC503 carrier mixer, producing 8.835MHz 1Vpp sinewave o/p.

Full performance now restored.
