An almost instant verie

US Hobby Pirate XFM has been active on 6285 kHz. I managed to hear them, quite well actually, at 0450 UTC. They gave an email address of XFMshortwave@gmail.com so I emaled them with a sound recording of the broadcast and almost instantly I got a shout out on air and an email back. They are 500 w apparently and as darkness fell here in New Zealand the signal improved markedly. On the SINPO scale I would say it is 35453. I am happy to count their email as a verie.
