[Elecraft] [K2] K2 to KXPA100, serial interface?

[Matt VK2RQ]

No, but if you change bands on the K2, a quick tap of the "dit" paddle will trigger the frequency counter in the KXPA100, and instantly recall the band pass filter/antenna selection/tuning solution for the new frequency. If you want the greater degree of integration that you mention below, you need to look at the KPA100/KAT100.

That said, it may well be possible for Elecraft to implement the sort of integration you mention between K2 and KXPA100; it would come down to whether they see it as a worthwhile investment of engineering resources.

I presume I would need to set the BPS to 4800 and either poll the K2 or turn AutoInfo on for this to work.  The assumption here is that the RJ45 TxD/RxD lines are carrying standard serial data at standard bit rates. If true, I would also expect to be able to talk to the K2 through the KXPA100 just as I would talk to a KX3.
