[Amps] LDMOS availability

Mon Jun 5 22:54:55 EDT 2017

Larry,

You made and proved my point for me. The transistor you mention is NOT an 
1400 watt class (as I specified in the email) in fact your transistor is not 
even close, it is closer to 140 watt out (if memory serves) That makes your 
statement off by a factor of 10. You asked me to be careful, I was very 
carful to specify 1400 watt class in my email.

Thank you , Bruce, W8HW

Bruce,

The MRF-150 came out in 1983/84 and Helge Granberg produced the Motorola
app not EB-104 using the XRF-150 in the same year.  It is still readily
available.  Be careful with your FACTS!
