430MHz FM Transceiver INCORPORATING A MICROCOMPUTER CPU control with ICOM's original programs provide various operating capabilities. No-backlash dial controlled by ICOM's unique rotary encoder circuit. The band-edge detector and Endless System provides out-of-band protection. There are no variable capacitors or dial gears, ensuring problem-free use. The IC-45A E can accomodate FM, coverage in the 430 ~ 440MHz IC-45A 440 ~ 450MHz) frequency range. MULTI-PURPOSE SCANNING The Memory Scan allows you to monitor five different memory channels and two VFO frequencies, and the Program Scan provides scanning between two programmed frequencies. The scanning speed is adjustable, and the auto-stop terminates scanning when a signal is received or a channel is empty. DUAL VFO'S Two separate VFO's can be used independently either for simplex operation or for duplex operation, and any desired 100KHz steps frequency can be split in duplex operation. CONTINUOUS TUNING SYSTEM ICOM's new continuous tuning system features an LED display that follows the tuning knob movement and provides an extremely accurate readout. Frequencies are displayed in 4 LED digits with a resolution of 5KHz. Automatic recycling restarts tuning at the top of the band, i.e., at 439.995MHz when the dial goes below 430.000MHz. Recycling changes 439.995MHz to 430.000MHz as well. Quick tuning in 25KHz steps is available with VFO "B", and is also provided for trouble free QSO IC-45A 439.995MHz and 430.000MHz should be read 449.995MHz and 440.000MHz.) OUTSTANDING PERFORMANCE The RF Amplifier and the first mixer use high performance FET's, and with other circuits provide excellent cross modulation and two-signal selectivity characteristics. The IC-45A E has excellent sensitivity, demanded especially for mobile operation, high stability, and with a pair of high quality monolithic crystal filters and ceramic filters, facilitates very stable receiving and excellent durability. The Transmitter uses the VCO signal which is locked at a half of the transmitting frequency and modulated with the microphone signals. This signal is doubled, amplified, and fed through band-pass filters and a high-performance low-pass filter. These systems provide distortion-free signals with a minimum spurious radiation level. The IC-45A E has everything you need to truely enjoy UHF FM operation, in an extremely compact, rugged Transceiver designed to ensure high quality, long term use.
