RF Tracking - adjusting T1, 2, 3

 

Has anyone actually done this part of the FT-301 alignment? On 4.0 MHz you adjust T2 & T3 for maximum output power. Then adjust T1 for best Rx sensitivity. Problem is that all three of these in the "Tune" or preselector section are seriously "gooped" in place. I could remove the hardened resinous material, follow the procedure, then use something to lock them in place again. But is it worth it??

This radio is putting out about 82-85 watts on 4.0 MHz, and sensitivity is pretty good. Maybe not worth it, just to do a "complete" alignment...?

Yes Joel….I did it ?and found some improvement, but the rig I was working on had had a hard life.
