Very difficult (but not impossible) for a singleton WOp to operate on 2 nets simultaneously! It is possible that there was, say, an Ops Net and an Admin Net. The Ops Net was worked all the time but the Admin Net was only worked, say, on the hour every hour. You could have one Tx/Rx tuned to one Net, and the other to the other. To work 2 Nets from the same set would require re-tuning to the frequencies of the Ďotherí Net every time you needed to change Nets! Re-tuning was not instantaneous. You needed to get the Tx/Rx up (and probably to change the length of the trailing aerial!). My guess (having only worked on the periphery of the Black Arts of the Wiggly Amps) is that the second set was simply a spare. After all, what use is a Catalina 3000 miles out over the ĎOggin if it canít report what it sees?
What we really need is an ex-Brass Pounder to give us ďThe GenĒ!!
