RIB and remote operating like N5J and others.

I view AA7JV's Radio In a Box as the greatest and most innovative engineering achievement in ham radio in my 69 years as a ham. It increases the likelihood of a team getting permission to activate islands that are a wildlife refuse, greatly reduces the difficulty of setting up decent stations on islands with difficult topgraphy, and greatly reduces the cost of expeditions by eliminating the need to set up an encampment of two dozen hams on an island or in an entity, to transport them there, and to maintain their human needs there for two weeks.

Those of us without heads in the sand may have noticed that ham radio has been graying out for decades, as many of us old-timers are dying out, AND WE ARE NOT BEING REPLACED in like numbers. An important innovation of the N5J operation was to involve both OT ops and new hams as remote operators.

The ONLY impact of these innovations on those of us at home has been that reduction of cost and difficulty of putting all those radios on the island, and to get them permission to be there. It has ZERO impact on our end of the QSO. There are radios and antennas on both end of the QSO, and a human operator is in control on both ends. The difference is that the human operators didn't all need to travel to the island -- only the much smaller team that set up and maintained the gear, which some of them built!

AA7JV introduced another important innovation at the Visalia DX Convention in 2019 that is quite important to we Topband OTs. Observing that in his many DX trips, propagation allowed nearly all of the most difficult QSOs on one or two nights of a 2-3 week trip, George developed a sophisticated combining network that allowed the two best weak signal modes, CW and FT8, to operate simultaneously into the same TX antenna, and to use the same weak signal RX antennas, allowing them to be active all night every night! The magnitude of this achievement technically is to realize that the two modes are working within 20 kHz of each other, and listening within 10 kHz, and the CW station is running high power!

George Wallner, AA7JV, is one of my heroes!

73, Jim K9YC
