ACOM 500S: compact solid-state HF/6 m/4 m amplifier, the lowest-power model of ACOM's S-series.
Drive power: about 35 W for rated output (the usage text says less than 50 W); RF gain 11.7 dB ±1.5 dB
IMD3: better than 30 dB below rated PEP; harmonics: better than 50 dBc below 30 MHz, 70 dBc above
Input SWR: below 1.5 (typically 1.2), 1.8-70.5 MHz; RF bypass SWR below 1.1
Antenna outputs: RF OUTPUT 1 is for direct connection to ACOM 04AT / 06AT tuners only; RF OUTPUT 2 is for an antenna or a non-ACOM tuner (SWR below 1.5 recommended, especially on 6 and 4 m)
Transceiver-independent: needs only ground-on-transmit and under 50 W drive
Coverage notes: 60 m 5.020-5.455 MHz, 6 m 50-54 MHz, 4 m 70-70.5 MHz; check regional band plans
Operating temperature: -10 to +40 °C; up to 3050 m without output reduction
FCC ID 2AJXZ500S (granted April 2023); CE
