*** E-MAIL YOUR RFQ FOR PRICING TO SALES@TACTICALGEARCOMMAND.COM *** Icom has developed the new flagship model IC-7800 which is a fusion of forty years of analog RF circuit development expertise, with cutting edge digital technology. The result is 110dB dynamic range, +40dB 3rd order intercept point in HF bands and other phenomenal performance features. The receivers combine various current and new technology, to obtain the +40dBm IP3, a specification never before achieved in Ham radio. Quite simply put, the IC-7800 is the ultimate Ham radio. Nothing else comes close! Astonishing +40dBm 3rd order intercept point (in the HF bands) Two completely independent receiver circuits allowing reception of two different bands in different modes simultaneously Four 32-bit DSP units and 24-bit AD / DA converters Digital IF filter Ultra high stability OCXO unit 200W output power and high stability transmitter +40dBm IP3(3rd order Intercept Point): Icom’s considerable analog RF circuit experience combined with cutting-edge digital technology results in an astonishing 110dB receiver dynamic range and a +40dBm IP3 in the HF bands. A first in Ham radio! To achieve this superior receiver performance, Icom’s engineering team completely re-engineered the whole analog circuit and matched it to the DSP units. Two completely independent receiver circuits: The dual receiver allows you to receive two different bands simultaneously in different modes, with each receiver not causing any adverse affect to the other one. Quad processing: The IC-7800 incorporates four independent, 32-bit DSP units and 24-bit AD/DA converters. By having four independent DSP units, the radio will respond to operator changes in an instant, as each DSP unit has a dedicated function. While there is one for each receiver, there is a DSP unit for transmit as well as a DSP unit for the Spectrum Scope. Digital IF filter: Icom’s digital IF filters give you performance that is not possible with crystal or mechanical filters. This allows the operator to adjust filter shaping (sharp or soft), filter bandwidth, and center frequency characteristics, without missing the action. Multiple filter memories store the last used filter settings by using operation mode. Ultra high stability OCXO unit: The IC-7800 uses the OCXO (Oven Control Crystal Oscillator) unit which is stable to within Ý0.05ppm at 0ÝC to 50ÝC. This specification means that even on the 50MHz band, frequency error is less than 2.5Hz! Real time spectrum scope: Due to the DSP unit for the scope, the IC- 7800’s spectrum scope provides excellent sensitivity, with 80dB of dynamic range. While the scope rivals many of today’s commercial test sets, there are 7 steps, ranging from Ý2.5kHz to Ý250kHz. This is up to 500kHz of spectrum! 7-inch wide color TFT LCD: An active matrix 7-inch (800+400 pixel) TFT color display was selected for the IC-7800. This large display shows main, sub-band frequencies, including various settings, and operating conditions, as well as the spectrum scope, S-meter, and RTTY/PSK31 decoded messages. The “virtual” S-meter shows high quality, analog-looking needle swings that are smooth and accurate. Other Outstanding Features: DSP controlled CW keying waveform shaping Multi-function electronic keyer with adjustable keying speed, dot-dash ratio and paddle polarity • AGC volume knob for fine tuning of the AGC time constant 3-step manual notch filter Microphone equalizer and adjustable transmit bandwidth Built-in RTTY and PSK31 modulator and demodulator Pre-amplifier and mixer circuit dedicated for 50MHz band High quality digital voice memory 64MB CF memory card for storing various personal settings Digital twin PBT eliminates interference from adjacent signals 16-step noise reduction 4 antenna connectors with automatic antenna selector Triple band stacking register Automatic antenna tuner Twin peak audio filter for RTTY operation Message memory for CW, RTTY and PSK31 operations 101 memory channels
