G1F: Standards for Power Amplifiers

External RF power amplifiers designed to operate below 144MHz may require FCC certification. Without a grant of FCC certification, you may only build or design only 1 external RF amplifiers capable of operation below 144 MHz in one calendar year.

If FCC certification of an external RF amplifier is required, the amplifier must not be capable of reaching its designed output power when driven with less than 50 watts.

The following WOULD DISQUALIFY an external RF power amplifier from being granted FCC certification: (A) The capability of being modified by the operator for use outside the amateur bands, (B) the capability of achieving full output power when driven with less than 50 watts, and (C) the capability of achieving full output power on amateur frequencies between 24 and 35 MHz. The capability of being switched by the operator to all amateur frequencies below 24 MHz would NOT disqualify an external RF power amplifier from being granted FCC certification.

The maximum symbol rate permitted for packet or RTTY emissions below 28 MHz is 300 bauds.

The maximum symbol rate permitted for packet RTTY or data emissions on the 10-meter band is 1200 bauds.

The maximum symbol rate permitted for packet, RTTY, or data emissions on the 6- and 2-meter bands is 19.6 kilobauds.

The maximum authorized bandwidth of RTTY, data or multiplexed emissions using an unspecified digital code on the 6- and 2-meter bands is 20 kHz.
