What a chain of "reflections", which is, of course, what a reflector is
about.
I also take into account Don's. G3XTT, comments under the Mega Station
subject line. The difference between 1500w and 2Kw is not much unlike
the difference between 400 to 1500. As I see that Lynch, Vine Antenna et
al do a good trade in 1500 watt amplifiers I am sure there are many
stations this weekend sending 5NN4TT who are understating the situation.
Of course we may be in a situation that comes under the heading of: "You
do not say and we will not ask". Most of the 1500 watt amplifier are key
down for ever types so the old excuse of running at 25% output does not
wash with me.
The problem comes to those who generally want to abide by the licence
but at the same time do not want to be at a competitive disadvantage.
They have an ethical dilemma, to run 400 and be at a competitive
disadvantage or run 1500 and operate outside the licence conditions. If
you are highly competitive then the decision is obvious, if on the other
hand you believe in the rule of law then you run at a competitive
disadvantage. Why should we put people in this position? They could
avoid it by going to the lower power categories but there is something
compelling about going for the "top" category especially for those who
are highly competitive.
I and many others on this reflector will remember the time we had
150watt DC input restrictions except top band with 10watts DC input. I
can remember competing in RTTY contests in the early 70s when that meant
no more than 100 watts output or may be 110 watts if the PA was very
efficient. Then some one came up with the idea that 100% modulated AM
with 150w DC input became an output of 400 watts of Peak Envelope Power
so we could run that on SSB and then a bit later all modes became 400
watts PEP. Technically a falsehood as a 150w DC PA could never give 400w
PEP output with good IMD performance. This, in my view, was a
bureaucrat's face saver and nothing else to enable us to run 400watts
out rather than 100.
We used to have no alternative to using normal length callsigns and that
has been changed to allow calls with just 3 or 4 characters for
contesting. This was done so that contesters were not disadvantaged
compared to the international competition. So why not 1500 watts of
legal power as we are not disadvantaged compared to the competition
unless of course we throw individual's ethics out of the window and
operate a "You don't say, we won't ask" policy. Unless some one can
think up another bureaucratic face saver?
