Wonder if anyone is using a K3 to work the WSJT meteor-scatter and/or EME digital modes on 6M. I'm just now starting to explore these modes with my current crummy rig (TS-2000), and it's really cool to be able to work this band with no ionospheric propagation. Additionally, MS will usually support shorter-distance propagation than an Es path, so it's a good way to fill in those close-in grid squares in the Es skip zone!
This is extreme weak-signal work -- oftentimes at or below the noise floor, and rarely more than 6 dB above it -- and one of the comments I'm hearing from a number of local guys is that "only one local station at a time can QSO (in the frequency sub-band of 50.240 to 50.310 MHz) because the QRM from adjacent-channel local signals will make it impossible for you to receive." Of course, all the local stations could synchronize TX and RX periods to solve this problem, but this isn't always practical or desirable. Seems to me that a K3 with the 2.8 kHz roofing filter, though, should be just fine with 5 kHz spacing from a strong local signal, or maybe even 3 kHz. Wondering if there is any actual experience with this yet.
