The on-list descriptions of K3DSPUPGD say it changes a few capacitors and other components to extend frequency response for TX and RX (in combination with firmware) below 300 Hz, but has no effect on the line in/line out jacks used by digimode programs. Is that still the description? In other words, is this change mostly for ESSB and high-quality audio needs, or is there some other advantage that might come about now our in the future from having this board? (Presumably with a KRX3 you need two of these and that gets a little pricey for something with uncertain benefit.)
