HW-101 for PSK31?

[David Griffin]

Glen,
You're right, of course.  Whatever was I thinking?   I was thinking input, 
of course and I was thinking that I remembered a number like that from the 
manual, which I haven't seen in years.  I have my old RCA Transmitting Tube 
Manual out and the highest I see for any kind of service is 70 watts.  Could 
Heath have been pushing the numbers over the top and hyping the PEP if you 
lit off a firecracker in front of the microphone?
Dave
