levels were mostly unpredictable in how they produced signal artifacts,

Hi Gord,
The ongoing worldwide supply chain debacle has impacted K4HD module
development. We’ve already redesigned PC boards twice to work around chip
shortages.
We’ll keep everyone updated.
Meanwhile, we’re hearing from those who took delivery of a K4D instead that

Gentlemen,

included and

I need that as well. The costs are adding

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.

Why is this theoretical? My interest in the question is for use with WSJT-X

Can the superhet option be switched in/out independently for each of the K4D
receivers?
For example it might be nice to run a full band skimmer on one receiver (so no
superhet) while still needing the strong signal performance on another receiver
(with superhet).

K4HD is still an active license. If the transceiver is free to the

for the variety callsign:)
