Ok Graham thanks for the info.
If it was on the same frquency that was probably Dennis and me. We've been on for abt an hour ...hee. Well I can only conclude it is ADSL because it is just raising the noise floor it is very subtle not really identifiable like say TV LTB, it's a mush. Frame ants help a bit but not as sensitive at the LW by a mile. I use everything SDR software to niose blank and is filtering down to 200hz and Xtal filters on my Kenwood TS690s which has all the filters. Its very depressing. I took my DC rx around to Chris XIZ abt 6miles away and I could hear you on RTTY the other day a smashing signal. I have a similar ant set up I have a higher ASL and I am in open fields about 1/2 to a mile from the rest of humanity but still have noise....dohh!!!
Any way gl Graham and thanks for the reports. Things will be picking up now with the season change so hope to hear you for a twoway on 500kc/s soon.

Ok Peter
Should of given you a cal then but was using the ft897 at the time , with no tx on 500 , good signal at the time , odd for mid day ? some cw on at the moment 1530 bst , but quite low .. may be the same tx ... noise level on the rx is showing s8 to s9 all day .... across the full band, interestingly the dsp noise reduction in the ft897
actually helps .. must be the right kind of noise ...
As for the rx .. well in a direct test , swopping from the ft897 and the ra1778m , the ft897 was giving a better recovery of the signal .. which is a bit disconcerting .. may be the wrong type of noise for the 1778 xtal filters (1.4 mhz and do tend to ring a bit if pinged) , but iv'e had a few replies lately where I could not resolve the other station, I think mainly due to the high level of noise a the qth

Thanks Graham
Not a beacon but a call, computer generated. Locally we try to have a qso weekdays at around 11:45 or at some time over the lunch hour and again later around 4:00 it is a very loose sched with M0JXM Dennis and rarely M0KHW.Ken. Rog GW3UEP listens some times whch is remarkable and reports by e-mail because I can't hear him its my RX or location (adsl noise?) that is poor but we should be reciprical.
FYI the current rig is an xtal controlled GW3UEP (ala UK500kHZ group) this week run off a laptop PSU very approx 35 watts output to a lw up 12m - 40m lng. Tnx fer rprt, meanwhile back to the RX with a big hammer.
