  1. Here's the way I read it: 95.1767(a)(1) Transmitter power of mobile, repeater, and base stations must not exceed 50 watts. This is for the "main" (a/k/a repeater input/output) channels. It seems that the term "fixed station" is no longer defined by the new rules, so that 15 watt limit seems meaningless. It appears that, with low-loss coax and a high-gain antenna, ERP could exceed 50 watts. 95.1767b limits all stations to 5 watts ERP when transmitting on the 7 interstitial channels at 462 MHz. 95.1767c limits all stations to 0.5 watts ERP when transmitting on the 7 interstitial channels at 467 MHz. So one has to take coax loss and antenna gain into account on these channels. If you have low-loss coax and a high-gain antenna, be careful! ERP is calculated using dBi, not dBd.
