[amsat-bb] Power output for using AO-73 transponder

FYI - In a sidebar on their website, AMSAT-UK requests that stations limit power output to 25W EIRP for using the AO-73's transponder.

"FUNcube-1 / AO-73 Radio Communications Subsystem • 145.935 MHz BPSK Telemetry 30 or 300 mW • Inverting SSB/CW transponder 300 mW PEP - 435.150 – 435.130 MHz Uplink LSB - 145.950 – 145.970 MHz Downlink USB Educational Telemetry beacon is 300 mW during day and 30 mW at night. Transponder is only active during night passes. Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna (25 w EIRP). Lower power will also work well. If adjusting for Doppler shift manually try tuning the uplink frequency while transmitting to keep the downlink constant."
