[Boatanchors] 813 grid to filament short

[Glen Zook]

With the exception of the 60-meter band, amateur radio operators are not limited to any ERP (effective radiated power) limitations.  Our limit, on HF, except for the 30-meter band, for those holding a license class of General, Advanced, or Amateur Extra, is 1500-watts out of the transmitter / amplifier.  For Novice and Technician class operators, they are restricted to 200-watts output as well as 200-watts output being the limit for the higher classes when operating in the 30-meter band.  Technician Class and higher class licensees, have the full 1500-watts output above 50 MHz.
On HF, it is possible to get gain, in the antenna, at least 10 dB.  This increases the ERP, if the output power is 1500-watts, to 15,000-watts.  On the VHF and UHF bands, antenna gain of at least 20 dB can be had by "stacking" antennas.  With 1500-watts out of the transmitter, the ERP, with 20 dB gain, would be 150,000-watts.  There are a relatively few operators, that have available, for UHF and SHF operations, antennas with at least 30 dB gain.  That means an ERP, with 1500-watts out of the transmitter, of 1,500,000-watts! Glen, K9STH

ERP is NOT what we are held to!

That is an entirely different animal than power out of our radios.

Repeaters and certain bands for experimental use get into ERP.

This is a herring tossed into the morass that is way off base.
