[Amps] FL-2100 Grid Metering

[VE6TI]

Thanks to all the responded to my inquiry earlier in the week, the  
suggestions were helpful and lead to discovery that I had indeed  
tapped into the relay coil line instead of the RFC.  Both lines are  
in the same bundle and have the same colour coding.  I had checked  
for continuity and the multi-meter "beeped" so I thought I had the  
right one.   Well at least that is my story and I'm sticking to it.

Having played with this a bit now on 20 meters I find that dipping  
the plate and loading for maximum power output for a given exciter  
setting is coincident with about 85 ma of grid current.  Additional  
loading does drop the output power slightly but also increases the  
grid current.  I could easily exceed 100 ma with a relatively small  
amount of added loading.  I have read several comments that one  
should advance the loading beyond maximum power output to reduce the  
grid current, however in this case the opposite is occurring.      
Perhaps this is why Yaesu did not include grid metering and advises  
dip and load for max plate current provided that it does not exceed  
0.5 A.

I will try the other bands out and if I find different behaviour will  
post again.

Thanks to all
