Re: [Elecraft] K3S (SDR/superhet hybrid) vs. entry-level direct-sampling radios

May I add that another good feature of a direct sampling SDR is low IMD in the passband. That is due to lack of crystal filter in the passband. The result is that that output audio is cleaner especially when there are several stations calling on the same frequency. 73, Igor UA9CDC

We’re quite familiar with this document. But blocking is blocking: a single strong signal in the passband of the RF band-pass filter can overrange the ADC, causing desense or spurious responses, thus requiring that gain be reduced ahead of it. Clever firmware can help, but it can’t overcome
