[Elecraft] KPXA-100 & K2 Integration?

[KJ]

Hello again all,
Can the KPXA-100 be fully integrated with the K2? Full QSK and so on? Appears to be mostly for the KX3 and KX2.
My 2003 K2 has all the options.

I can't believe Elecraft discontinued the 100w amp for the K2. What do have then?
A full featured, basically, QRP radio! These little 5 watt jobs are 1/8th the size but maybe w/o all the bands and there all over the place for sale.

Should have bought the KPA-100 back then but the $$ weren't there!!
Anybody has one up for sale....let me know....

Thanks!! Ken
