I think the PC must have decided I needed a fiddle!Roger G3XBMhttps://www.blogger.com/profile/13673890140751539870noreply@blogger.comtag:blogger.com,1999:blog-9071048343455395511.post-87051340409253697022014-10-06T13:56:02.456+01:002014-10-06T13:56:02.456+01:00Roger,

I can't see much point in raising the signal and the noise-floor by the same amount ;-) Pre-amps have a place, but only at the other end of the feed-line in my opinion.<br /><br />My guess is that the only significant difference between us is the antenna. Mine is a simple horizontal dipole at about 7m, fed with about 15m of RG-8X (a little under 1dB loss on 10m).<br /><br />Also, during working hours I have a fairly quiet local noise environment.<br /><br />Another thought - It couldn't be the rain today perhaps? Is water getting in somewhere?<br /><br />David G0LRDDavid (G0LRD)https://www.blogger.com/profile/11377879585873483008noreply@blogger.comtag:blogger.com,1999:blog-9071048343455395511.post-20841869483154568042014-10-06T12:31:42.016+01:002014-10-06T12:31:42.016+01:00Hello Roger, it could be soundcard settings? Could...Hello Roger, it could be soundcard settings? Could be you got IPO and ATT switched on? Or it could be the antenna/coax. So many different things you could check. There could also be a difference betweens WSPR-X and old WSPR 2. I don't know that for shure. But you could try. I just tested versions of JT65-HF and WSJT-X and compared receive. Lot's of differences between them. See my blog. 73, BasPE4BAS, Bashttps://www.blogger.com/profile/12958141238330445285noreply@blogger.com
