2 things: I see that the K3 can delay RF generation before keying the amp relay but what about, upon key up, delaying amp delay until RF ceases? How is this accomplished. Is it included? 2. The K3's keyer is excellent but it's a ratio adjustment, not weight as indicated. The dit length or heaviness is non adjustable. This is like most JA rigs and is really strange. Why would anyone want long dahs like a bug? A real weight control shortens both dits and dahs equally and makes overall keying sound more choppy or heavier. Although the K3's weight is about right, some of us would prefer lighter weight for high speed and heavy weight for bad conditions. This goes way back to the early days of Morse.
