Thank you for the response! If I were to use a Y-cable, that plugged into both KEY and ACC2 (ACC2 via 3.5mm-to-2.5mm adapter), would this work? My key is only a straight key, but for some reason, it has a stereo (not mono) 3.5mm plug. I'm curious: Would it be possible to add a software feature to allow the use of a key as a PTT switch? It seems rather strange to have the key toggle TX/RX in CW mode just fine, but to lock out that function in all other modes except for CW. As the KX3 is very small and compact, it would be an advantage to minimize the cables, and maximize the functions available through existing accessories. Allowing a single key to be used for both CW and PTT would make a lot of sense. Thank you! I'm glad you have an accessory cable kit available. Finding good 3.5mm to 2.5mm adapters that actually work seems to be unusually difficult. Most of them are made for cellular headsets (4-pin), not stereo headphones (3-pin). I realize that space was limited on the KX3 to use standard 3.5mm cables everywhere, but it's still a disappointment to not have standardized on a single cable size.
