It appears that for the ARRL contest, and maybe for CQ contest, 150 watts is the break point between high and low power. Does anyone know why that limit was set? It would seem that changing it to 200
Back in the 1950s and 1960s a pair of 807s or 6146s ran 150 watts INPUT. 73 Frank W3LPL It appears that for the ARRL contest, and maybe for CQ contest, 150 watts is the break point between high and l
In the days of tube radios, 100 w often wasn't the ceiling barefoot, with the exception of some transmitters/transceivers that could push out 400. 150 is a good compromise. It gives some headroom to
Thanks for all of the clarifications about this rule, and it does seem to be rather unique to the ARRL as the lower power limit for CQ contests is 100 watts. I am sure someone has entered low power r
John, If memory serves, and I well could be wrong, this dates back to the point in time when we "switched" from measuring DC input power to the finals to output power. Consider that most 'standard' r
There are way more radios that DON'T do 200 watts than there are that do. 73 Tom W7WHY _______________________________________________ CQ-Contest mailing list CQ-Contest@contesting.com http://lists.c
W3LPL is correct. Years ago we could run 150 watts input which is about 100 watts out now. It was easy to figure input (voltage times current). I had a club official come by and certify that I was le
Few contesters today think about INPUT versus OUTPUT power. They think about the manufacturer specification of transmit power. My first nice rig was the Yaesu FT-101E, with two 6146 tubes in push-pul
In 1959, my first Field Day, 150 watts input power was one of the multiplier categories. During the 1960s it was hanged to 200 watts input power Twenty years later is was changed again, to today's 15
100W output is adequate for nearly all today's transmitters. IMD properties for the expensive transceiver boxes are much better than at 200W out. These hams set the power output to 100W. They set it
My FTdx5000 is a 200W rig. But I can throttle it back to as low as 10W max output, in 10W increments. I presume other rigs have a similar governor. 73, de Hans, KØHB "Just a boy and his radio" ______
Hello, Jukka, OH6LI, just about nailed it for keeping or returning the contests LP max. output to 100W. 73, Mike, K4GMH _______________________________________________ CQ-Contest mailing list CQ-Cont
way back when for some reason i entered a 100 LP class for some contest, and the only power meter i had was an eico 7 something SWR meter. i got a set of carbon reisiters to 50 ohms and measured the
