G0UPL in the Caribbean, QRSS DXHans, G0UPL is running a 30-metre band QRSS station on 10140.070 kHz, from Grenada until July 28. QRSS is extremely slow CW, dot lengths of 10 to 30 seconds are typically used. Decoding is by a PC and free software to extract the CW characters from below the audible noise floor. . Hans writes: Well, Wednesday 15 July, 3am in London, the packing was done and I started work on designing, building and debugging a 30m QRSS beacon to take with me to Grenada. 2 hours later it was time to wake up XYL and get ready to leave for the airport at 5:45am. I just about managed to make the beacon work in those 2 hours, which was no mean feat... nobody said it's the most elegant design, but it works and puts out around 150mW. This evening I spent a little time antenna farming and hung a 30m dipole, orientated to point best at Europe. The QRSS signal is on 10,140,070 or so (will drift down a few 10's of Hz perhaps, when the tropical heat starts up tomorrow morning). Power is 150mW or so, and the PSU is my 5V Nokia mobile phone charger (saves bringing along a separate PSU!). Some photos here: I will be QRV until 28-Jul-09. I have already seen the beacon on the online QRSS grabbers of G8NXD, ON5EX and W1BW so know the sigs are getting out FB! Not bad, everything survived the 9 hour flight and customs, and within moments of powering up I could see the signals clear on G8NXD's webpage http://www.pencoys.org.uk/g8nxd.jpg . Anyone wants to have a listen, please do and send me your reports! If you haven't tried QRSS before, you should have a go! Lots of fun! Any receiving stations wanting a DX QSL card, I will prepare one when I get back to G-land! 72/3 de Hans G0UPL Tropical QRSS QRSS links to free PC software GQRP Yahoo List GQRP Club. Their quarterly magazine SPRAT provides a fascinating read containing articles of varying complexity, from simple test equipment, to fully functioning radio transmitters and receivers.
