Re: Topband: Spurious Signal on 1810.8
Now peaking S8.5 at 3:45am EDT (0745 UTC) Oct 3rd, and after more listening I would say it's 90 degrees from my location (EM69xx) near Indianapolis based on it being just slightly stronger on average on my 40 degree pennant compared with my 160 degree pennant (very similar response that I have when copying AA1K right now, and he is 93.6 degrees from my location.

Location: FN02mq antenna: 160m inv vee ( sorry no directonal antennas - down for repairs) Last night: 10 over S9, one fade down to S9 over the course of a few hours. This morning: S7, started fading around 1200z - once to zero ( so suddenly, I thought it was shut off, but it slowly came back). I did observe that around 1157z, the frequency abruptly shifted down and returned. This occurred a few more times afterwards, but with no discernable pattern.

Re: Topband: Spurious Signal on 1810.8
I did a quick plot of 8 stations giving directional info on the spurious signal. The report from WT3Q SE of here S8 to 9 fn20ac helps narrow it down. The data suggest eastern PA (around Philadelphia), northern Delaware (Wilmington), or the lower part of NJ (toward Atlantic City). More reports from hams near Baltimore, Philadelphia, and NYC would be useful. 73, Paul K5ESW ___ Remember the PreStew coming on October 20th. http://www.kkn.net/stew for more info.

For some while I have been hearing a strong spurious signal on about 1810.8 kHz. I thought it was a local SMPS or similar until I started trying to find it. It is not local to me it - I can hear it on several different antenna systems, and also from my remote station 15 km away. It beams south west and is inaudible during the day.

East from near Erie, PA. No SE antenna to try, so can't determine if the signal favors that direction from here or not. Freq. is 1810.53 when zero-beat in CW, but does not seem particularly stable, moving +/- several Hz in a short period of time.

Re: Topband: Spurious Signal on 1810.8
Gentlemen, I honestly thought that was a growler here at my house (typically caused by a wallwart or TV) and had no idea that others were hearing it. Today I took another look at it and opened up one of my favorite spectrum monitoring tools. I recorded the spectrum as well as the audio. Please note that at this location FM19nm it shows clear 60Hz spectral lines and you can clearly see descrete frequencies on the spectrum display. Attached is a link on my WEB site where you can observe the spectrum (.JPG) and an audio file (.WMV). These should be usable by most of our users I hope. At my location I observed an S5 signal on my inverted L and when switching to the Beverage (aimed at about 35 degrees) was S1.5 I hope this is what everyone is seeing and I am interested in finding this as well.. Now does anyone have a signal about 1.836 there abouts? Jim WA3MEJ ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

Re: Topband: Spurious Signal on 1810.8
From eastern MA (FN42gk) the signal is very strong in the daytime and nighttime. This appears to indicate that the source is within groundwave distance of me. I tried getting a direction fix this evening with my RX vertical array that can switch in 8 directions. However, I see very little signal change with direction, which tends to indicate the propagation, at least after dark, is very high angle. There may be a very slight peak to the southwest or west, but I can't be sure because the differences are so small. I'll try getting a daytime fix, maybe tomorrow morning after sunrise, when the propagation should become predominantly groundwave and a direction fix should be more reliable. 73, John W1FV ___ UR RST IS ... ... ..9 QSB QSB - hw?
