Testing the Perseus (software 1.1.b vs 1.1.c)
Indeed the latest version runs quite OK even on my laptop (T40, with 512 MB memory, 1.3 GHz processor) and on my old table-top (Fujitsu) of 3.0 GHz/1.5 Gb mem. only slightly better actually. All these recording 1600 kHz RF-file. And the new file being 16-bit file, it saves HD and now you can record (without modifying the windows parameters) 5 minutes files (of about 2.2 Gb each). The latest version has also the “zoom” when you can zoom the frequency reading to be able to read rather precise frequencies down to below 1 Hz. However on my setups, it is still rather slow and there are problems when trying to do that when playing back the recorded file. Still I find easier to use SpectruVue for exact frequency read-out. Otherwise the Perseus software is fine with many bells and whistles like the DSP-noise reduction etc. Well done, Nico.
August/September: Dario goes King´s Village´s DX (sdr & car-dx)

DX-meeting at Haapavesi with Aurora Borealis and the EDXC
After Dario’s DX-days I drove to Haapavesi-QTH with Viktor Rytkovsky (picked up at the trailway station Kouvola). We went via Joensuu and took MR (Mauno Ritola) with us. As always during the last years we soon noticed geomagnetic disturbance starting when driving up North! And indeed at the night 4th Sept we could even see the Aurora Borealis. Thanks to Jari Ylioja – an active photographer of Space & Aurora (more Jari´s pictures at SpaceWeather Auroa Gallery) the

Some DX in August– September
So far I am still waiting to be able to use my Far East BOG. So most DX is made using my longwire of

KING'S VILLAGE STATION OF THE MONTH - AUGUST: Rádio Itapirema 1390
This station was particularly interesting as it took some days to discover what is doing a strong het on 1390.0 kHz. Soon I noted the signal is coming from
I am not sure if this split still exists, later on I have noted Rádio Jornal here (which is more usual at my QTH).
KING´S VILLAGE STATION OF THE MONTH – SEPTEMBER: Radio Libertad,
This station was first noted on Sept. 29th with nice Andean music. First it was a bit difficult to say what station is saying “Libertad” here although the music was “very Andean” music with nice melodies. The station even had time signals which were rather exact (not so familiar on Latins). Soon I noted the loggings of last year (credits to JMS, JEÖ and TSM in
Radio Libertad with same kind of programming and announcements – and on the same split! The station has been dominating the channel also after September – many times in October – sometimes with good signal and only some QRM from at least two others (one being Venezuela with Nat. Anthem at 0430 – this one a bit above on 1310.01, the other one with programs sounding like Radio Maria – could be Radio Maria, Panama (carrier frequency rather near the nominal). Radio Libertad has also web-pages and program feed on web - very nice! On October 7th some other stations from Perú were noted with good signal.
