If you want to be even more effective for CW pileups, add and SDR/SKIMMER to the subrx IF output. You can see the calls of the stations in the pileup on a "band map/waterfall" display. IDing the frequency last worked is considerably easier with both KRX-3 audio and the SKIMMER display. Putting VFO B on the frequency last worked is as easy as clicking on the call.
