I explained that mobile and fixed stations need different supplies, and so they're sold separately. However, her question has piqued my curiousity, and I'll ask the rrab readers to answer one of mine: why were the transmitters of "twin" receiver/transmitter combos, such as the R-4/T-4 pair, designed with separate supplies? If there are any historians reading this, I'd appreciate your insights into why the design went in this direction.
