FlexRadio Aurora 500W HF+6M SDR Transceivers
FlexRadio AURORA™ SERIES is an all-new family of HF + 6M transceivers featuring the world's first truly integrated 500 watt SDR transmitter. The Aurora Series defines a new category in amateur radio, eliminating the traditional boundaries between transceiver, amplifier, tuner, and power supply. Designed for the modern operator, the Aurora Series delivers exceptional RF performance in a radically compact form factor—leveraging cutting-edge high-efficiency technology that produces more power with less weight, lower heat, and dramatically reduced power input requirements. Aurora Series transceivers are network ready, designed for remote access with SmartSDR clients on any Windows, macOS, iPad®, iPhone®, or Maestro™ device, in your shack, easy chair, or from virtually anywhere in the world! All four Aurora versions offer full coverage reception of 30 kHz to 54 MHz in real time for complete visibility and control across the bands. The AU-510/510M has a single SCU (Spectral Capture Unit) that digitizes the RF spectrum for signal processing and display, supporting up to 2 slice receivers and 2 simultaneous panadapters.

ACOM 2000A Automatic HF Linear Amplifiers
ACOM 2000A Automatic HF Linear Amplifiers are the world's most advanced amplifiers designed specifically for hams. These amplifiers were the first to include fully-automatic tuning and sophisticated digital-control capabilities. ACOM's revolutionary 2000A amplifiers deliver maximum legal power in all modes and operate on all amateur HF bands 160 to 10 meters. Be sure to read the SPECIAL Note, below. These amplifiers follow your transceiver's band and frequency automatically in far less than a second. No special cables are required: Just a "dit" on CW or "AHH" on SSB is enough for instant band and band segment changes. ACOM 2000A amps break every amateur band into multiple frequency segments. The user can store up to ten (10) sets of tuning adjustments for every frequency segment - allowing individual settings for multiple antennas on each band. By completely eliminating time-consuming tune-up procedures, ACOM 2000A linear amplifiers give contesters a real edge. At the core of the ACOM 2000A is a classic HF amplifier design that employs two matched 4CX800A high-performance ceramic-metal tetrodes for maximum efficiency. ACOM uses these rigorously tested tubes with today's most advanced digital control technology to create an amplifier with outstanding performance, features and reliability. Measured third and fifth order IMD are typically 40dB and 45dB down, respectively. Typical harmonic emissions are as low as -55dBc (second) and below -70dBc (for third and above). Thus, probability of QRM, BCI or TVI is dramatically minimized. ACOM's 2000A remote diagnostic features and modular design ease fault isolation and repair. The protection system makes damaging one of these amplifiers difficult. Information on the 12 most recent protection trips is stored in an INFO BOX for remote diagnostics via phone line, PC, and Internet. Full break-in (QSK) is based on a built-in vacuum relay. Transmit/receive switching sequence is secured by a dedicated microprocessor. * Frequency Coverage: All Amateur Bands 1.8-29.7 MHz * Power Output: 1,500W PEP, 1,500W continuous carrier (the external auxiliary fan must be installed for operations of continuous carrier transmissions longer than 15 minutes * Hum and noise: Better than 35dB below rated output * Harmonics Output Suppression: Better than 50dB below rated output * Input and Output Impedance: Nominal values: 50 Ohm unbalanced output; Input circuit: broadband, VSWR less than 1.3:1, 1.8-29.7 MHz Amateur Bands (no tuning, no switching); Relay Bypass Throughput: VSWR less than 1.1:1, 1.8-29.7 MHz Amateur Bands * Automatic Tuning: Load Impedance Matching - less than 3 seconds; Band Change - less than one second; Segment Change - less than 0.2 seconds * RF Gain: 14.5dB, frequency response less than 0.5dB (50 to 60W drive power for rated output) * ALC: grid-current derived, -11V max, rear panel adjustable * Primary Power: 180-264V (200, 220 and 240V nominal taps, 10 percent tolerance), 50-60Hz, single phase, 3,500VA consumption at rated output * SPECIAL Note: Order part number AOM-2000A to wire the AC plug yourself; order part number AOM-2000A-240 for pre-wired 240 volt operation * Complies CE safety and electromagnetic compatibility requirements, as well as FCC regulations * Size: W 17.3 x 19.7 x H 7.1 in.
