Re: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz
More information on the nature of the signal can be found here: http://www.topbandhams.com/tech-page/30-washing-machine-daylight-recording-k3pgp I did not hear it at all last night (Tuesday). It was weak but audible here Monday night, but I noticed propagation was flaky, apparently affected by a solar event. SWBC stations on 40m were weak with a lot of flutter and fade. _ Topband Reflector Archives - http://www.contesting.com/_topband

Hi Doug Last night I told w1fv that my estimate was 70 to 75 deg from my location in Fishers IN and a heading of 70 deg from my location clips the bottom tip of Nova Scotia, while 75 deg runs me through Cape Cod. Therefore having very strong signal in southern part of Maine fits in well with what I am seeing. Need some good directional headings from Maine, New Hampshire, and Nova Scotia.

It's peaking at S9 on 1.912 right now -- 0900 EST. At times, the pulsing portion of the signal becomes inaudible but the raspy carrier remains at full strength.

Re: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz
All: Turned on my radio to listen to the ARRL 160, and saw it. First thought was what piece of crap in my house is doing THAT. But as we now know, its something big. Since CODAR was suggested, I compared it to CODAR around 4.8 MHz. Similar, but not the same. BW is similar, but the CODAR I saw sweeps high to low about once every 1.5 seconds where this sweeps low to high about 3 times per second. CODAR looks to be one carrier (with some pulse-ish modulation) while this one looks to be two carriers, one delayed by a short time interval (maybe 100 ms.) and starting at a slightly (aprox. 200 Hz) higher frequency. Carriers modulated with a fast rise time waveform, giving us the raspy sound. Hope this info helps us figure out what this is. 73, Mike, WV2ZOW On Tue, Dec 9, 2014 at 9:55 AM, Roger D Johnson n...@roadrunner.com wrote: Here is a YouTube video of a CODAR signal.

I live in Southern ME, next to the NH border and 30 miles inland. I listened on 1.915 MHz at 1815 Z today, (Tuesday) and could hear it quite well at about S5 with my NE beverage. When I changed to my vertical to receive, I could barely detect it in the noise. My beverage is aimed at 45 degrees true. So it can't be too far away if I can hear it at mid day.

Re: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz
The signal is at times peaking at S9+20 here in central Ohio, with a bandwidth from approximately 1900 to 1930. It appears to be rapidly sweeping up the band at a rate of about four sweeps per second. You can definitely observe the doppler effect by slewing your rig up and down the band while listening for the rapidity of the pulses.

The fact that Mike VE9AA could not hear it on ground wave, means that is likely more than a few hundred km's from his location. The would possibly eliminate New Brunswick, Nova Scotia, Newfoundland and PEI. However, it would leave Labrador and then Greenland as part of the picture.

Hi Mike and gang, I have been monitoring the signal during the early hours of this morning and on web SDR in England it was there at 3am EST but when I checked again at 4:20am EST it was no longer being received. The heading from my house has been very consistent at approximately 75 degrees but somewhat difficult to determine exactly due to the pulsing nature of the signal. Signal still S9 at my location near Indianapolis at 7am EST. Signal is definitely at a heading greater than 45 degrees at my location based on numerous methods I have available, and estimated around 75 deg. As I type the signal just about dropped below my noise level at 7:04am (I thought it abruptly stopped but it is still there but right at my noise level at 7:10am EST I currently only have Internet via cellphone due to a large area outage on ATT DSL and when I get internet coverage back I will plot my heading to the signal to see what it shows.

Re: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz
Same estimated heading (~75 deg) from the Boston area and same as last night. The relatively big signal strength suggests something in NA rather than EU. But that would place it almost out a sea from here, or possibly very southern VE1 or FP8. Is there anyone from that area that can give a report or heading? If it's Europe, it would point to the CT/EA area, or it could be northern Africa (CN, EA9, etc.). The heading is definitely too far south for the signal to have its origins in places like TF or OX. 73, John W1FV -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Don Kirk Sent: Monday, December 08, 2014 8:50 PM To: Michael Walker Cc: K2RS; Mike Waters; topband Subject: Re: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz Copying the signal again this evening from Indianapolis area at 8:45pm EST (0145 utc) Heading is again approximately 75 deg.

Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz
Kind of a pulsating buzzing sound, centred around 1915, but audible down to slightly below 1900 and up to approximately 1925. At its centre frequency last night (Saturday), it was just as strong as any CW contest signal. It was particularly loud (S9 + 30) in the Northeast and ops with beverage antennas are reporting that it appears to be coming over the horizon in a south easterly direction, while others say it is possibly coming from Europe or Polar Russia. Whether this is a harmonic, a spur or something coming from an intentional radiator, it has made regular QSO operation between 1900 and 1930 almost unbearable for the past three nights now. All the more reason to hope that the FCC goes ahead and adopts their proposed reallocation of 1900-2000 to delete sharing with radiolocation and to restore amateurs to primary status. Although many 160m ops seemed to blow off this NPRM while the comment period was still open as if it were much ado about nothing, a few of us maintained that it was of utmost importance for the amateur community to flood the Commission with comments supporting their proposal. Although GPS has pretty much killed 160m radiolocation for the moment, we never know when some new service might attempt to start up in this part of the spectrum under the guise of Radiolocation. That could be what's happening right now. For those only interested in DX and contesting in the bottom end of the band and who sometimes appear not to even consider 1900-2000 as part of the band, still must remember that if some new service were to displace amateurs from the top half, congestion in the 1800-1900 kHz segment (including the DX window) would likely become unbearable. The FCC proposal, if adopted, would protect amateur status in the entire 160m band once and for all, and let's hope it is not already too late. _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz
Intruders are becoming endemic on all the hf bands, not just top band. Every morning I hear SSB stations on the low end of 80m and 40m, and the worst of all are 10m-12m, which have become a nightmare of swishing signals, carriers, buzzing sounds and illegal CBers. I hadn't realized how bad the situation had become till I could see the spectrum on my Flex transceiver. Most ot the problem seems to be coming from the North in the afternoon, when those bands are open into Asia. I can't imagine how bad all this crap must sound to our JA friends. 73, Jim W8ZR -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Donald Chester Sent: Sunday, December 07, 2014 1:55 PM To: topband@contesting.com Subject: Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz Kind of a pulsating buzzing sound, centred around 1915, but audible down to slightly below 1900 and up to approximately 1925.

John W1FV, You and I are in very close agreement on heading because you are 73 degrees from me and we are both saying approximately 75 degrees. I can hear it on numerous web SDR receivers that are located in Europe (England, etc.).

It's peaking at 15 over 9 here in SW Connecticut right now. I first heard this noise last Thursday evening (12/4) around 0300Z. Signal strength was between 20 and 30 over 9 at that time. My friend Fred, K2DFC, in NJ heard it then too, with a signal strength of 20 over 9. Since then, he's heard it a few times during the day, but the signal strength is weaker during daylight hours.
