Very interesting propagation today on 1900 kHz. Just a few minutes before 1730UT there was a quick KGØVL-W4DEX solid 808 mile copy CW contact. There was no signal detected on the same path the previous three days. WW8II/4 operating from Georgetown, GA copied the CW QSO. The distance between WW8II/4 and KGØVL is approximately 833 miles.

Initially WW8II/4 (360 miles) was Q5 S1 SSB copy at W4DEX. Also WB4EZ's (202 miles) initial transmission was a stable S3 copy. KM4GBM (165 miles) checked in. After the initial comments from the above propagation seems to have changed dramatically. WW8II/4 was not copyable and there was no signal from WB4EZ and KM4GBM. K4CFZ local to W4DEX observed the same. W4WAV checked in just as we were closing the session. His signal was stable at S5 at 31 miles from W4DEX

At the end of the seccion another CW call was made by W4DEX to KGØVL and another Q5 QSO was made. The signal was noticeably better than at the beginning of the session. A mode change to SSB also produced a quick Q5 exchange.
