Hello VLF,
also I have the decode of VO1NA transmissions (confirmed by Joe).
Stacking procedure of files from 30 Dec to 10 Jan give me this decode (message deleted) without false decodes:

Last three nights very poor T/A reception, noise has been high.
But a good transmission - 13/14 decoded at Hawley without stacking.
