[Elecraft] am for the k2

[EricJ]

I've been using my K2 as a VFO for my Drake 2-NT for the last several weeks,
including SKN this year. Got quite a few "HUH??" reactions. Hi.

You can see what's involved at:

I'm retiring it tomorrow, though. I just finished putting a KD1JV DDS
controller, DDS-60 and Keyall in a little sloping case that sits by my
straight key. Heresy for try boatanchor fans, but it works.

Not sure why anyone would want to put a K2 on AM. There are so many great
old boatanchors available for AM. Not only do you get a rig MADE for AM, you
get a rig that reminds you of the K2's place in history. Spend a week or so
with some 60's gear, even very good receivers like my 2-B, and you will be
reminded how very far engineers like Wayne Burdick and his contemporaries
have brought the state of receiver art.

I know of at least one AM'er I saw online that ised his K2 as a (n
expensive) VFO for this tube transmitter.

You won't find AM'ers always "on frequency", as most old vfo's are only
accurate to 5kHz (1kHz with Collins).

I have thought of playing with AM (tx and rx) with a K1 or K2 when I get
one. 
But I would doubt Elecraft themselves would bother with such endeavors,
especially on a rig that is designed to be such a fine CW rig.

The issues I think I would encounter are:

rx:
1) detection: cut the BFO and perhaps insert a diode detector
2) bandwidth: would have to open up to at least 4kHz

tx:
1) modulation: you could just drop a book on the key in CW mode and then you
need to modulate with voice, one way might be via series PDM modulation
