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.
