Content preview: After several attempts Tom G8HUH managed to decode my WSPR15 transmission on 137.607kHz this evening. As the FT817 was drifting around 4Hz in the 15 minute TX slot with the FT817 on 1837.607kHz (I was using a stabilised sig gen for the LO at 1.7MHz), I think this was messing up the decodes as Tom only gave me -32 and -34dB S/N whereas I have been getting some 6dB BETTER than this with the WSPR2 transmissions.

If WSPR15 is going to succeed for me I need a more stable rig (or a 0.5ppm TXCO fitted to the FT817) or a fan to force cool the FT817 - even when running 500mW! I'll leave the rig on for a little while longer, but will probably revert to WSPR2 for the rest of the evening. Thank you Tom G8HUH, and Trevor G0KTN, for working with me for the last couple of hours to get this as good as I could. 73s Roger G3XBM -- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk https://sites.google.com/site/sub9khz/ http://qss2.blogspot.com/ http://www.youtube.com/user/G3XBM --047d7b6d88daaf854804d4d6e928 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable
