They are running the REAL WSJTx in F/H mode.  I called them a few times and my Enable Tx timed out after 2 minutes, as expected.  I was doing something else and they popped my Tx back on in an unsuccessful attempt to receive their RR73.  I'm on an EFHW and they are pretty much off the end of it.  

I got them on many bands back in 2018, but not 30m.  So I'll try from time to time.  They just pop in and out at -17 or so.  Last night they were approaching +00 at times on 20m.
