GM, My TS-850 apparently took a RX front end overload this past weekend and has lower sensitivity and RF output from 30m up. (Make that 0rf on 10m). Am courious about K0ZL mod on http://n6tr.jzap.com/850repair.html#Reduced_receiver_sensitivity_and_transm has anyone used this? Are there any other suggestions for Front end protection? Thanks, Chuck N7BV
