HF+50 MHz ALL MODE COMMUNICATIONS RECEIVER
Expanded frequency coverageThe IC-R75 covers a frequency rangethat’s wider than other HF receivers;0.03–60.000000 MHz*. This wide fre-quency coverage allows you to listen to avariety of communications including ma-rine communications, amateur radio, shortwave radio broadcasts and more.*Guaranteed 0.1–29.99 MHz and 50–54 MHz only
High stability receiver circuitIcom’s latest wide band technology pro-vides highly stable receive sensitivity overthe entire receive frequency range. TheIC-R75 makes it easy to catch communi-cations world wide.
Superior dynamic rangeA wide dynamic range of more than 100dB*1, 104.5 dB*2 for 14 MHz band, 102.5dB*2 for 50 MHz band, and a well-de-signed triple conversion system help min-
imize image and spurious responses forbetter signal fidelity.*1 Not guaranteed.*2 Not guaranteed; When PREAMP OFF; CW
narrow 500 Hz bandwidth; 100 kHz channelspacing
Twin PBT capabilityThe PBT (passband tuning) function nar-rows and moves the IF passband at twostages to efficiently eliminate interferingsignals.
DSP capabilitiesDSP (Digital Signal Processor) filtering in theAF stage is available with the optional UT-106 DSP UNIT*. The DSP provides the fol-lowing functions: * Already installed with some versions.
Noise reduction:Pulls desired AF signals from noise. Out-standing S/N ratio is achieved, providingclean audio in SSB, AM and FM. Pull weaksignals right out of the noise.
Automatic Notch filter:This automatically minimizes beat signalsand protects the receive signal. Also, thenotch frequency is automatically adjusted tofollow interfering beat signals—reducing in-terference from RTTY signals during SSBoperation for example.
FM mode standardUnlike many other HF/50 MHz receiversthere is no need to install an additionalunit for FM mode reception on the 29 and50 MHz bands.
