Hi, it seems that 40m isn't the only band these people have invaded. I did a little listening between 10 and 12 MHz last night and found the same type of chanting on various frequencies between the two above. I also recorded some chanting on 11425 kHz which is attached (only a minute or so - short r...

Well done Mark. Last decode (RTTY) here was at 7475m with the balloon on the way down around 160km ESE of Adelaide. Signal lost shortly after. Used a dual band (2m/70cm) vertical colinear antenna about 6m agl into an Icom R7000 receiver. $$$$$VK5ARG-1,884,05209:03,-35.643561,140.098892,7475,0,10,184...

Last decode of PS-45 from me (PF95gc) at 16:36, a distance of 281.6Km and elevation of 0.5.

$$PS-45,1066,16:36:01,-33.6154,141.1368,8781,76.10,10,3,-33,3353,0000 1101*69CB

Using a dual band 2m/70cm colinear vertical antenna at 6m agl and an Icom R7000 RX.

Well done Andy

Here is a screenshot taken during a geomagnetic storm of a WSPR signal from VK7VF on the 10th of January.
Both signals (VK7DIK and VK7VF close together at 1158) are normal but at 1214 and 1218 VK7VF's signal got
frequency shifted.

Here are some interesting spots that were received overnight. 2014-12-07 16:36 VK4TVL 50.294477 -22 QH30jq +43 VK2CBL QF56hh 1643 Km 2014-12-07 16:26 VK4TVL 50.294477 -18 QH30jq +43 VK2CBL QF56hh 1643 Km 2014-12-07 16:16 VK4TVL 50.294477 -19 QH30jq +43 VK2CBL QF56hh 1643 Km 2014-12-07 14:32 VK2CBL 5...

Hi Adrian, > Have setup the laptop with WSPR 2.11 with 2 cables, speaker out to mic socket (using vox) and speaker out to mic socket on laptop > but I am not decoding anything. Any ideas? From previous experience with laptop mic in sockets, the one I played with exhibited wicked AGC when feeding spe...

Hi,
here is a screen shot of an aircraft reflection on VK5KC's signal on 6m wspr.
Also visible (just) is VK5BC/p from Corny Point.

The aircraft in question was a police helicopter doing a search to the north
and north east of my qth. Yagi was beaming to VK4 (north east) at the time.

Hi Leigh,

yes, a lot of aircraft reflections from air traffic to my West (Gulf St. Vincent).
I also get reflections from aircraft to the East at times.

The joys of living close to an airport
Cheers Leigh.

Hi, here are some screen shots of a wspr signal from Brian VK5BC taken Thursday 27-11-14. The station (at the time) here comprises of a 5 element yagi approximately 4 metres agl into an IC-7000. I was beaming directly East and Brian was at his station at Corny point on the York peninsula (West of Ad...

Another pic of 2m wspr with the strange signal.

I also noticed some scattering on local 2m wspr signals this morning Leigh.
In the display there is also a strange signal - not sure what it is !?

Cheers.

Hi all,
here is a screen capture of a possible aircraft doppler wspr signal from VK5LA.
The reason I suspect it is from VK5LA is that Leigh VK2KRR decoded his signal
at the time (too much doppler for wspr to decode here).

G'day Leigh, I think John was beaming VK6 when the scattering was evident. G'Day Glenn, In my own case, bearing in mind that I am in the "burbs and suffer with all sorts of noises, I set the filter on the IC-7000 at 1200 Hz for WSPR operation and use that on all bands. If you are away from subu...

Some scattering occurred on 6m WSPR signals today. The interesting one was a local
signal by VK5SIX which suffered some scattering then returned to normal fairly quickly
as the screen capture below shows.

Hi all, This may be an interest to Leigh VK2KRR. Propagation on 160m tonight has been very poor, lots of noise (constant) up to S9+10dB on the guess meter :wink: . The screen captures below show some of the noise (possibly sun/ionospheric disturbance) I got and the effect it had on signal levels. Th...

G'day,

Just thought I would post a screen grab of some signals.

Hi Leigh,
thought you might like to see what I see at this end on 2m wspr.
Problem is I live close to Adelaide airport hence all the crazy AE
especially on VK5KK's signal (flightpaths are between his station and mine).

Cheers.

Just thought I would post some screen captures of 2m wspr activity around the Adelaide area.
The signals seen on these are received on a vertical dual band colinear antenna EG: nothing fancy.

G'day Peter, I find it surprising that you find the IC-R7100 deaf and that you need to use a preamp. I have the slightly older IC-R7000 (specs are similar) and it has a hot receiver. Its AM airband performance is fantastic as long as you have a decent external speaker and a reasonable antenna. It wi...

G'day all,

Sorry all, it was indeed a mistake on my part

Those stations as listed on 6m were not, they were stations on 40m.
That's what I got for doing too many things at once

Again, apologies to all.
Rob.
