"I don't recommend removing TR32 as it disables VR12 ALC, SSB power will be at full blast. 

Instead clip or remove R249. This only disables AMC not ALC. 
Tune L40, L43, L44, and L33 for maximum forward swing on wattmeter.
 
Adjust AM power for no more than 5 watts dead-key - if running a linear amp set at 3 watts dead-key. 
Adjust ALC for no more than 20 - 25 watts PEP on SSB. 


Roger Beep Switch: Insert switch in-line with C134. To change length of beep, play with value of C134.
