ACOM 2100: 1500 W tube amplifier for 160-6 m, rated for PEP and continuous carrier alike.
Drive power: 50-85 W for rated output; RF gain 13 dB typically, response flat within 1 dB
IMD: better than 32 dB below rated output; harmonics: better than 50 dB (1.8-29.7 MHz), 66 dB (50-54 MHz); hum and buzz: better than 40 dB below rated output or 1% AM
The March 2016 user manual differs from the current product-page specification table on harmonics (manual: better than 50 dB at 1.8-21.5 MHz and 66 dB at 24-54 MHz) and RF gain (manual: 13.5 dB typically). Current product-page values are used in the fields above.
Input SWR below 1.3:1, 1.8-54 MHz; bypass SWR below 1.1:1
Output match: SWR up to 3:1 or higher at reduced output levels
Tube: single 4CX1000A / 8168 (1000 W plate dissipation, forced air, class AB1)
Withstands up to 400 W reflected power; fault signatures of the last 7 protection trips stored
Shipped in two cartons (amplifier 17.0 kg, transformer 16.5 kg)
Coverage: the current official product-page band list is 160, 80, 40, 30, 20, 17, 15, 12, 10 and 6 m; 60 m is not listed. The March 2016 user manual says "all amateur bands 1.8-54 MHz" without a band-by-band list and does not mention 60 m.
The March 2016 user manual requires the external auxiliary fan for continuous-carrier transmissions longer than 5 minutes; the current product page does not repeat this.
FCC ID 2AJXZ2100 (granted July 2017); CE
