Jon, Your 1/3 rule is right for continuous duty data modes like RTTY, but I understand (and have not tried to figure out the details for myself) that plain PSK31 does not come up to a full duty cycle - something about the coding, so you might go up to 1/2 the normal rated power - 6 or 7 watts.
If you push it more than that, put your hand on the bottom rear cover once in a while. If it is too hot to hold your finger on it constantly, then you should back off the power a bit. 73, Don W3FPR On 3/27/2011 6:23 PM, jon.perelst...@gmail.com wrote: > Duhhhhh!
