Strictly for IC-705 . It will not fit IC-706, IC-7000, or any other Icom mobile. Some sellers mistakenly list it for other models – check compatibility before purchase.
AM operations remain a vibrant sub-hobby within amateur radio. Enthusiasts gather on frequencies like 29.000 MHz for "AM nights." The UI-7 allows operators to join these vintage circles without needing an entirely separate, bulky transmitter setup. Installation Overview icom ui-7 am fm unit
