[Elecraft] KPA1500 and FT8

[Ed W0YK]

Using 1500 watts in a digital mode like FT8 "may be" an unwarranted bad practice, but none of the reasons cited here is justification for prohibiting the practice.  It's like arguing that compromised antennas and unfavorable QTHs "should " only use QRP because that's common practice. 
The amount of power used in any situation should  be no more than needed to achieve reliable communication.   Because FT8 is an effective weak signal mode, the need for high power should be far less frequent than other modes, but that's not justification for prohibiting high power.
The reason for restricting power level to that needed for reliable communication is to minimize QRM to neighboring QSOs.  That may mean that while the use of high power FT8 may be required for a specific QSO, it may be inappropriate within the same audio sub-band where many other FT8 users will be negatively impacted.

Using 1500 watts on a digital mode (except for RTTY) is unwarranted a 
bad practice.  I've been using the new digital modes since PSK31 
started.  I was on the bleeding edge of working with PSK in its earliest 
days.  This is the first time I've heard anyone try to justify using 
that kind of wattage on a weak signal mode.  The vast majority of those 
who use the JT modes (including FT8) consider QRO to be 100 watts.  As I 
said what you are doing is legal, but it does fly in the face of the 
general consensus among users of these modes.  If a poll was taken of 
users of these modes, I'm quite certain your position would be a 
distinct minority.  73 de Carl N8VZ
