Hi Bill, Hopefully you’ll get some responses to this question from those with direct experience. But looking at it theoretically: both the 7300 and 7610 are direct-sampling radios with about 25-30 dB less blocking dynamic range than the K3 or K3S. On Field Day this could have a definite impact when using multiple transmitters on the same band, or even on different bands, depending on antenna spacing and power level used. Dynamic range of all of these radios is quantified in the receiver performance table at www.sherweng.com, specifically the fifth column (“100 kHz Blocking”).
