operator in the driver’s seat. The knob has a substantial, easy-to-grip, rubberized outer ring plus the now customary tuning dimple, and I preferred it to the PROIII’s main tuning knob. It’s possible to manually adjust the tuning dial tension with a slider beneath the knob — no screwdriver needed! ICOM followed through elsewhere on the front panel with larger knobs that offer a more positive sense of control. Even the inner concentric controls are easy to maneuver.

choice on F-4, while in CW mode, the same key opens one of two selectable KEY menus, and in RTTY mode it opens the decoder screen. Pressing and holding the primary MENU button takes you into SET MODE, letting you enable or adjust those parameters less-traveled. I found menu scrolling to be counterintuitive. You press the ∨ key to ascend the menu tree and the ∧ key to descend.
1 kHz, 2 kHz, 5 kHz etc. You then tune to the blip to hear what’s there. You can use this tool to seek activity on one of the three band stacking registers, then swapping to a second band register to dial up the signal without tuning away from your original frequency. You can monitor SWR and relative power output (there’s no level or percentage readout) at the same time, although I still prefer a “real” meter or at least a digital representation, such as the virtual meter on the IC-7600.
predecessors in the IC-746 series and the IC-756 series. ICOM does advise users not to place anything on top of the IC-7410. And Furthermore . . . Where does the IC-7410 fit into the larger Amateur Radio transceiver market? While the IC-7410 occupies the middle ground in terms of price, its performance definitely trends toward that of higher-tier transceivers. An IC-7410 goes for approximately $2000 at the big outlets, and the optional 6 and 3 kHz filters are about $125 apiece.
