N1BUG: 160 Meter Sound Clips


On this page is a collection of sound files representing some of the DX I have worked or heard on 160 meters. These files do not represent every DX station or entity I have worked. They are intended to illustrate the nature of DXing on 160. Recordings are made as a matter of convenience when doing so is practical and does not interfere with working the DX!

These files have not been processed or enhanced. This is audio exactly as I hear it from my receiver while operating. Files prior to May 2007 do have some distortion due to overdriving the sound card input while recording.

As of March 19, 2013, files have been converted to monaural and file sizes reduced without loss of quality.

For some long haul DX there can be several possible paths (short, long, and skew). Where known, I have indicated the direciton of signal arrival for the longer paths and polar paths.

I have sorted the files by continent, except Asia I have broken into three sections based on perceived difficulty. This is a rather "fuzzy" distinction. Japan might not be any harder than some of the paths in Mid Asia... while some of the paths in "Mid Asia" may become just as difficult as the Far Asia paths in times of higher solar activity. Also, some in Oceania are just as difficult as Far/Mid Asia... for example Guam.



Far Asia
These are the most difficult paths from Maine, because the direct (and long) paths are either high latitude or polar, traversing the auroral zones.
9M2AX 2006 Nov 20 Near his sunrise. Path unknown because all I had for transmit and receive antenna at this time was an inverted V at 75 feet. This is the strongest I have ever heard Ross. It seems likely his signal was high angle that day, though I cannot confirm that.
9M2AX 2012 Jan 03 Near his sunrise working K1UO.
9M2AX 2012 Jan 03 Near his sunrise working N1RJ.
9M4SLL 2013 Mar 11 Spratly Is. Peaked on south path about 3 to 5 minutes after my sunrise. Excellent copy but was unable to QSO.
BU2AQ 2010 Nov 09 Heard via unknown path. Initially the path seemed to be alternating between southwest and northwest, but later his signal was about equal on south, southwest, west, and northwest Beverages. This suggests the signal may have been arriving at high angle from an unknown direction.
DU7ET 2013 Mar 15 Closer to his sunset than my sunrise, south path.
DU7ET 2013 Mar 15 After my QSO he got even stronger! But faded long before my sunrise.
JA1HQT 2007 Jan 14 Near my sunrise, northwest path.
JA8ISU 2009 Oct 29 Near my sunrise, northwest path. For the JA>Maine path, this is a huge signal!
JA0QNJ 2007 Jan 14 Near my sunrise, northwest path.
JD1BMH 2011 Jan 02 Weak, but workable. What a pleasant surprise! I believe I was Harry's first W1 from JD1/O.
JT1CO 2009 Dec 11 Shortly before my sunrise. North path. Notice how he comes out of the noise just long enough for a QSO, then fades again. I was lucky!
JT0YAB 2010 Nov 01 Shortly after my sunset.
RA0FF 2010 Nov 06 Near my sunrise, northwest path.
RA0QC 2009 Jan 23 Near his sunrise, north path.
V84SMD 2012 Nov 20 South to Southeast path between my sunset and his sunrise.
XU7ACY 2010 Nov 09 Via long path (south/southwest) just before my sunrise. Peter reported high QRN this day and I am shocked I got through! This was my first 160m Asia QSO on the S/SW path.
XU7ACY 2010 Jan 28 Near his sunrise. Skew path over Europe (Northeast).
XU7ACY 2011 Feb 12 It is amazing how oftem Peter is workable!
XU7ACY / JT1CO 2011 Feb 14 This was bizarre. I heard Peter and Chak only on my South Beverage on this evening. This is a large file. I am including the whole 10 minute segment as recorded during this unusual event.
YC0LOW/1 2011 Jan 15 Jo had a good signal but was struggling with noise on his end.
HS0ZKX 1
HS0ZKX 2
2013 Dec 03 Via SW path. First file (1) is our QSO; second file (2) is the peak about 3 to 4 minutes later.
 
 
Mid Asia
These are challenging or infrequent paths due to being relatively high latitude.
4S7NE 2007 Jan 18 Evening, northeast path.
EY7AF 2007 Jan 29 Near his sunrise, northeast path.
EY8MM 2013 Feb 20 Evening, northeast path.
EY8/K4ZW 2009 Jan 31 Evening, northeast path.
RZ0AF 2008 Nov 22 Evening, north path. This is an incredible signal for a polar path!
RZ0BA 2010 Nov 03 Evening, north path.
UA9YAB 2007 Feb 11 Evening, north path.
UK8DAN 2011 Feb 02 I had worked this station before, but this is probably the best I have ever heard him. Not bad for 70 watts to a low wire antenna!
UK8GK 2007 Feb 12 Evening, northeast path.
UN5J 2011 Feb 13 Not an easy QSO but we made it!
VU2BGS 2010 Jan 17 Near his sunrise, northeast path. Kumar was running 70 watts to a 12 meter high wire vertical on the roof!
 
 
Other Asia
These are relatively easy, mid latitude paths.
4L/UT5EO 2010 Nov 26

KH2/N2NL 2010 Nov 03 Weak, propagation not especially good this day. All those years of EME were good training for copying in conditions like this! The power was out on Guam, so Dave (running on a generator) had very quiet receiving conditions.

VK6GX 2008 Oct 22 Near my sunset, but VK6 is nearly antipodal from here and is just as workable the other way around at my sunrise.
VK6HD 2006 Nov 08 Also near my sunset... but really, they are workable the other way around!
VK6HD 2011 Dec 24 See! This QSO was near my sunrise.

I have been asked what plasma TV noise sounds like on the bands. Here are two samples. The first one is noise from a plasma TV on 10 meters. At the beginning of the file I was using a 2.4 kHz filter with the receiver tuned to the center of the noise. Later I tuned back and forth through the noise with both wide (2.4 kHz) and narrow (300 Hz filters). The time line is as follows:
0:00 - 0:47 steady noise, 2.4 KHz filter
0:47 - 1:20 tuning through the noise with 2.4 kHz filter
     0:56 brief silence as I tuned out of the noise
     1:10 brief silence as I tuned out of the noise
1:20 I switch to 300 Hz filter and begin tuning back and forth through the noise
     1:43 brief silence as I tuned out of the noise
     1:48 brief silence as I tuned out of the noise
Plasma TV on 10m Band

Next is plasma TV interference on 160 meters, first with a wide filter, then narrow, as before.
0:00 - 0:25 steady noise, 2.4 kHz filter
0:25 - 0:50 tuning through the noise with 2.4 kHz filter
     0:30 brief silence as I tuned out of the noise
     0:42 brief silence as I tuned out of the noise
0:50 I switch to 300 Hz filter and being tuning back and forth through the noise
     1:01 brief silence as I tuned out of the noise
     1:18 brief silence as I tuned out of the noise
Plasma TV on 160m Band
