[Yaesu] Part for FT-100

[KC3VO at aol.com]

YAESU discontinued the RADIO, not the part!   YAESU had to stop  production 
of the FT-100 because MOTOROLA stopped making the  transistor!   (It was NOT 
Yaesu's desire that things happened this  way, and there is NO equal replacement 
for the part.) The closest alternate  parts are intended for 24 to 28 volt 
operation, and will give only 15 to 20  watts after careful circuit 
modifications, on 13.8 volts. POLYFET transistor  company has said they are working on a 
similar device for 12 to 14 volt  operation, but I have yet to see or obtain 
one.
  I believe the original device was made ESPECIALLY FOR the FT-100, by  
MOTOROLA, and sold ONLY to YAESU, so it is VERY UNLIKELY that you will find a  
substitute with EQUAL performance, unless POLYFET or another manufacturer  decides 
to create a similar device.
  Sorry for the BAD news.------------73, and Happy Holidays!-Bob  Curry, KC3VO
