Hi Tom, I'm sorry for my delayed response to this thread but I was traveling today. 

The last time you raised this topic with me, Dec 28, 2011 in my records, 
I did send you a "rationale."  You thanked me for the reply and commented that 
"The low power facet of this contest is what I find most fun..." 

I will reiterate my rationale, that "low power" is a large part of what makes the NAQP 
contests fun, since people feel they are on a more balanced playing field where they 
will not be "stomped" by high power stations. In the past, there were complaints about 
excessive power. This rule  tries to make clear that our power limit is 100 watts, not 
assisted by an external amplifier capable of more than 100 W output. I think that 
allowing such amplifiers would lead to more "mistakes" and complaints. The goal of 
the contest is fun and skill development, neither of which is helped by allowing 
external amplifiers capable of more than 100 W output. 

We do want to have one consistent set of rules for the three NAQP contest modes 
(RTTY, CW and SSB), and so far the three NCJ Contest Managers (RTTY, CW, SSB) 
haven't agreed to eliminate the rule "no external amplifiers capable of more than 100 W 
output." But, I will make sure we consider it again later this year, for next year's rules. 

Hi John W8WEJ, The last time this "no external amps" question was discussed 
on the RTTY reflector was Feb 26, 2015. (Two days before the contest!) Since 
we only revise the rules once a year (before January), I am not surprised that you 
have "...heard nothing since..." 

I'm sorry you consider it "a dumb rule." Perhaps you can see that I might consider 
an environment of warmed-up, on-line, and already operating high power amplifiers 
puts the important "low power" aspect of this contest at risk. 

Just FYI:  I am a long-time user of the Kenwood TS-590s, and I will note it is 
rated for 100W on all modes including RTTY. The In-Depth-Manual even has a graph 
showing the TS-590s "transmitting continuously for more than two hours at a 
25°C or 77°F room temperature with an output power of 100 W."  I have operated 
them extensively on RTTY and never had a concern with the usual short contest 
exchanges. 

Hi Jeff WK6I, The rule does not apply to your example of  "10W radios using 
external amps to get to 100W."  The rule applies to external amplifiers capable 
of more than 100 W output. A KX3 driving a KXPA100 is fine. A K2 or K3/10 
driving a KPA100 is fine. If someone has a specific, not hypothetical, question 
about their amplifier stage please send it to me. 

Sorry if I'm a little grumpy today. Traveling does that to me. I need a little 
contest fun to relax... See you Saturday!
