This allows the operator to adjust filter shaping (sharp or soft), filter bandwidth, and center frequency characteristics, without missing the action. More info: Email Subscription You are not subscribed to this review.
Dealers, and pricing should be available soon. There is even a separate preamp and mixer for the 6 meter band.

The other AGC loop detects the AGC voltage at the digital IF filter output which has only passed the intended signal and draws the full potential from the digital IF filter. The first AGC loop prevents saturation of the 1st IF amplifier. The AGC voltages detected in front of and behind the digital IF filter in the DSP unit. Multiple AGC loops The IC-7800 has multiple AGC loops. This system provides wide dynamic range, reducing the distortion from strong signals and lower intermodulation. The image rejection mixer for the 2nd stage reduces signal distortion through IF processing and provides a high-fidelity signal to the DSP unit. They provide a powerful 200W output power at full duty cycle and low transmit intermodulation. 200W output power at full duty cycle The newly designed push-pull power amplifiers using power MOS-FETs work on 48V DC. In addition, a total 8 channels of RTTY and PSK31 transmit memory stores up to 70 characters of often used messages for each channel. In the PSK mode, the AFC function tracks the receiving signal for accurate tuning and the NET function allows you to send at the shifted frequency. To reduce errors in receiving RTTY, the IC-7800 has a digital twin peak filter to reduce interference from other signals in the band. While decoded RTTY and PSK31 is shown on the 7-inch display, simply connect a USB keyboard to the IC-7800 to send as well. RigPix Database - Icom - IC-7800 Last modified Icom IC-7800 SPECIFICATIONS Type: Amateur HF/VHF transceiver Frequency range: TX: 10-160 m + WARC / 6 m RX: 0.03-60 MHz Mode: AM/FM/SSB/CW/RTTY/PSK31 RF Power output: 5-200 W (AM: 5-50 W) 100% duty cycle! Adjustable noise blanker A newly designed, digital noise blanker significantly reduces pulse type noise. By suppressing the noise components, an outstanding signal-to-noise ratio is achieved, providing clean, clear audio in all modes without distortion of the target signal. A total of 90.Īdditionally, the filter shape of the Manual Notch can be adjusted in three steps, with more than 70dB of attenuation! Variable level noise reduction The 32-bit DSP processing power of the IC-7800 produces real results by separating a signal component from the noise with the variable noise reduction. Continuing with this tradition, Icom announces the groundbreaking IC-7800! CQ, or contest number in up to four memory locations.
