For the user who values portability and raw performance above all else, the IC-R6 is a legendary and time-tested choice.
was silent. Only a single, clean sine wave at 440 Hz. But when he left the UI-7 on that frequency overnight, he woke up with a nosebleed and the word “Tacoma” written on his palm in black marker. He had no memory of writing it.
Turn off the transceiver. Disconnect the DC power cable, antenna coax, and all grounding wires. Let the unit sit for 5 minutes to allow internal capacitors to discharge. icom ui7 am fm unit
Replace the top and bottom chassis covers and secure the screws. Reconnect the power supply and an appropriate wideband antenna.
When slotted into a compatible transceiver like the Icom IC-725 , the UI-7 modifies the radio's RF generation behavior: Performance with UI-7 10 to 100 Watts (continuously adjustable) AM Output Power 10 to 40 Watts carrier maximum FM Modulation Variable reactance frequency modulation AM Modulation Low power modulation FM Receiver System Triple-conversion superheterodyne (via 455 kHz 3rd IF) FM Squelch Sensitivity Less than 0.3 µV (with preamplifier ON) For the user who values portability and raw
Tuning is achieved via the main dial (VFO) or direct frequency entry on the microphone. The display shows the broadcast frequency on the transceiver’s LCD screen. Memory channels allow the storage of favorite stations.
For amateur radio hobbyists, installing the UI-7 is highly accessible and requires minimal technical expertise. But when he left the UI-7 on that
Fully integrated with the radio’s main VFO (Variable Frequency Oscillator) tuning dial, memory channels, and front-panel mode selectors. Step-by-Step Installation Guide
