Summary

1. For SSB use a peak reading wattmeter to measure Px

2. Use carrier (key down) for all other modes to measure Py

Maximum output power – Advanced Station

135.7-137.8 kHz – 1 watt effective radiated power

472-479 kHz – 5 watts effective radiated power

All other bands:

400 watts Peak Envelope Power (PEP – also known as Px) for the following modes:

(a)       analogue television; or

(b)       Single Side Band (SSB) suppressed carrier; or

(c)        SSB reduced carrier.

For other modes – maximum output power 120 watts mean power (also known as Py)*.

Maximum output power – Standard Station

Maximum output power 100 watts PEP for the following modes:

(a)       SSB suppressed carrier; or

(b)       SSB reduced carrier.

For other modes – maximum output power 30 watts mean power.*

Maximum output power – Foundation Station

Maximum output power 10 watts PEP for all modes.

*Measuring CW (Morse Code) power output

CW (Morse Code) power output is measured with the transmitter keyed – that is, the radio transmitting a carrier with no modulation.
