[Elecraft] K4HD question

[Grant Youngman]

Any of these things you mentioned  might not bother you now BECAUSE you are using a K3.

The K4D adds a second A/D chain with dedicated front end filters for whatever band the second receiver is tuned to.  Plus diversity reception.

I seem to recall some reference to a “wide-band” mode, which may come in to play if the two receivers in the K4 are tuned to widely disparate frequencies (e.g., one on 80M, one on 20M).  This could exacerbate the A/D overload issue with wide-band direct sampled SDRs.   Wouldn’t be an issue with the K4D.  Although you might need a K4HD to get to the heat-proof front end you currently have with the K3.
