Just has a QSL received from Coast FM "Tenerife's official British Radio Station". i heard them on 6285kHz on 1st April so fairly prompt response. i also received a bumper sticker. the station only has a 600W TX but no details available on the antenna. I'm in the UK, using a Lowe HF 250 RX and a 20m longwire. they also have a 500W TX on 4025kHz, which i couldn't hear.
This snippet from their website gives a bit more insight...http://www.coastfmtenerife.com/
