You can go to the FCC site and pull Part 95 like I just did and read
it for yourself.
I'm running 50w from my Micor rptr. xmtr. with 1.5db loss from a MOt.
1504 duplexer into 50' of 1/2' LDF4-50 heliax to a DB410 9.2db gain
omni antenna. This all calculates out to approx. slightly more than
250W ERP. This machine has been in service for at least 25 years on
462/467. 675 in the Atlanta Ga. area
