Is this just a rumor or factual?  I find the idea that this actually
has happened to be very scary (the "unannounced" part).

There's an IMD mod to the Hardware AGC circuit. It is not complicated and can be done with leaded components (or SMT) in a few minutes. I do not know if it has been added to production radios yet or if the ARRL's unit has it.

There have been several versions of it. Perhaps Elecraft hasn't settled on a final version.

Improvements in turnaround time for AMTOR (etc.) have been made in firmware. Further improvement is planned; I don't know if it will be made in firmware or hardware

There is a single capacitor whose value was changed to improve CW waveshape.

I'm sure that at some point -- if it is decided to add these changes to production radios -- Elecraft will tell us what serial numbers are affected and how to do them if we wish, just like they did with the K2.

If they are not announced, it's not because they will be forever secret. It's because the Elecraft staff has plenty to do without dealing with this right now.

Would it be better for Elecraft to not make any changes where they see an opportunity for improvement?
