This IC is designed as double conversion RF block integrated Pre-Amplifier + RF/IF down-converter + PLL frequency. RTTY /PSK31 operation without PC connection The IC-7800 has a modulator and.REFERENCE FREQUENCY 16.368 MHz, 2nd IF FREQUENCY 4.092 MHz RF/IF FREQUENCY DOWN-CONVERTER + PLL FREQUENCY SYNTHESIZER IC FOR GPS RECEIVER DESCRIPTION The µPB1007K is a silicon monolithic integrated circuit for GPS receiver. When notching the same carrier signal, the AF Gain on the IC-7800 has to be turned all the way up to give the same audio output as in the IC-781.Professional communications receiver with 0.005 to 3335MHz coverage and high performance spectrum scopeAlso, a 10MHz reference frequency can be input/output for external equipment. 4.3 Manual Notch The notch functions of both IC-781 and IC-7800 are effective, but the IC-7800 has a much deeper notch. Among big guns, IC-7800 is your combat fighter.

It is possi-ble to encode and decode PSK31 as well as bau-dot RTTY signals by simply connecting a USB keyboard to the IC-7800. RTTY /PSK31 operation without PC connection The IC-7800 has a modulator and demodulator for the 2 major HF Amateur digital modes. The IC-7610 the 2.the receiving frequency in the scope screen. A 10 MHz reference signal, for higher frequency precision.

The digital twin PBT nar-rows and shifts the IF passband to effi-ciently eliminate undesired signals.* For FM, WFM and P25 mode, the passband width is fixed.Wideband coverageThe IC-R9500 covers 0.0053335MHz in SSB, AM, FM (WFM), CW, FSK and P25* modes. A special input for a 10 MHz reference signal, for higher frequency precision.Digital IF filterThe digital IF filter* allows the operator to adjust the filter shape (sharp or soft), filter bandwidth, and center frequency characteristics. IC7800 HF/50MHz Transceiver Features Icom America.

The 10MHz reference frequency can either be supplied to or input from external equipment.1604000 3000 2000 12000 3000 4000 5000 6000Multi functionspectrum scopeUsing a dedicated DSP unit improves the dynamic range of the spectrum scope. By using the power of two independent DSP units, the radio can respond to operator changes in an instant.0.05ppm high frequency stabilityThe IC-R9500 uses an OCXO (Oven Control Crystal Oscillator) unit which provides 0.05ppm frequency stability from 0C to 50C. * At 15MHz reception, with 5kHz separation signals.Dual DSPThe IC-R9500 incorporates two indepen-dent, 32-bit floating point DSP units, a dedicated DSP unit for receiver functions and another for the spectrum scope. The 3kHz roofing filter provides a 130dB (approx.)* blocking dynamic range. In very crowded RF spectrum conditions, it is extremely im-portant to protect against strong in-band signals. IP3 performance is +9.8dBm at 50MHz and +6.2dBm at 620MHz (+5dBm (typical) from 30MHz to 3335MHz).Five roofing filtersThe IC-R9500 has 5 independent roofing filters (240, 50, 15, 6 and 3kHz) for im-proved selectivity.

This means that two strong beat signals can be eliminated at once even while using the auto notch filter.Synchronous AM detectionThe synchronous AM (S-AM) detection prov ides less dis tor ted audio than normal diode detection. Sweep speed/span/ filter width setting Peak search function Peak hold function Attenuator Mini scope functionMini scope function exampleFix mode setting exampleTwo-point manual notch filterThe digital manual notch filter has a depth of more than 70dB at two points with adjustable filter width (wide, middle, narrow). The receiv-ing frequency is always centered on the scope screen.Wide band scope receives up to 500MHz. The scope screen shifts as the receiving frequency moves.

The multi-function spec-trum scope is displayed in vivid color. For example, use VFO-1 for the 7MHz band, VFO-2 for the VHF marine band,7-inch wide color TFT LCDThe large 7-inch wide (800 480 pixels) ac tive matr ix display delivers quick response time, high resolution and has a wide viewing angle. Twin peak filter Water-fall indicator FSK-R mode FSK tone and shift frequencies programmable10 VFOsThe IC-R9500 has 10 VFO channels for tuning and storing operating frequencies, mode, filter width and other settings. In addition, upper or lower sideband demodulation for S-AM is selectable for eliminating interference from adjacent strong signals.FSK demodulator & decoderThe IC-R9500 has built-in FSK demodu-lator and decoder. The IC-R9500 can recreate the carrier signal exactly by using the DSP.

When the VFO is changed, the settings are automatically stored in that VFO channel.A total of1220 memory channelsThe IC-R9500 has a to tal o f 1220 memory channels. You can quickly change the operating bands with the 10-keypad. You can use these to target the specific noise interference.Noise reductionThe noise reduction function separates signal components from random noise through Digital Signal Processing (DSP) and enhances the signals bur ied in noise for improved signal readability.VFO-3 for the 1200MHz band, etc. The noise blanker has two channels with adjustable width and depth parameters. The dB, dB(emf) and dBm meter have 3dB of accuracy (10 to 70dB signal from 100kHz to 3335MHz at 25C).Noise blankerThe IC-R9500 has a DSP controlled noise blanker that significantly reduces pulse type noise and improves the S/N ratio by remov-ing interfering noise. In addition, the IC-R9500 has a VGA connector allowing you to connect an external monitor.Multiple RSSIS-meter, dB, dB(emf) and dBm meter types are selectable in the IC-R9500.

In SQ1 mode, up to 130 minutes (approx.) of recorded audio can be stored into the CF memory. The sampling rate is variable from 8kHz (SQ1) to 48kHz (SHQ). One is the regular recorder, recording for long periods in WAV format into the built-in CF mem-ory or an external USB memory. 1000ch regular memory channels 20ch scan edge channels 100 auto memory write channels 100 memory scan skip channelsDigital voice recorderThe IC-R9500 has two types of digital voice recorders. By connecting to a USB keyboard, you can edit memory contents directly. Memory channels are grouped into 10 memory banks.
