Icom Reflector group:
   I have enough information now on adjusting the bias on the soon to be 
replaced driver. The information from VA7OJ coupled with two of your 
procedures for adjusting the bias current ( 1 amp per device ), slightly 
varying in how and where to read the current,  will allow us to get the job 
done.  Unfortunately RF Parts wants a minimum order of $25 plus shipping, 
and Chinese vendors only want $3 each plus $3 shipping, but there is a 14 
day shipping delay getting the parts to me. A local person has the drivers 
but we can not get them yet (long story), so we are without drivers. I 
wanted two, one for a future backup, in case the currently working one 
becomes defective. Again, THANKS to those who replied.

Subject: [ICOM] bias setting on driver RD15HVF1

Group:
   Have one of the drivers out on the PROIII, the RD15HVF1. I do NOT have a 
tech manual. When I have installed the new driver transistor what is the 
bias setting procedure?
