• Fixes a compatibility issue with CWSkimmer under Windows Vista.

To install just unzip and install in the Perseus software and CWSkimmer folders.

A new version of the Perseus software has been released, features and fixes are as follows:

Version 2.1i fixes some minor issues contained in the previous software version v2.1h:

• Preselection filters button misalignment in the Front-End panel
• System Date changes prevent software to be run unless fully registered
• New Marker Log File Format

Download at source here.

 

Just a quick note to let everyone know that versuon 2.1H has been released today by Nico.

It is a larger install as you get new drivers. WinUSB is used and this gets around the issues of signed drivers in Windows 64bit OSes. Download at source.

What's new:

- Fully featured demonstration version.
- WinUSB drivers and new Perseus control DLL for Microsoft Windows Vista and Windows 7 - 32 and 64 bit versions.
- Support for multiple Perseus receivers attached to a single PC.
- New FPGA cores with 48, 96, 192 kHz output sample rates.
- Direct support for CW Skimmer.
- Support for external frequency down-converters.
- Spectrum Display Max Hold/Clear/Pause Functions.
- New Waterfall Processing Modes.
- Waterfall Automatic Gain Control Options.
- Waterfall Time Ticks.
- User Configurable Color Palette.
- Markers Log.
- New S-Meter and Marker Units.
- Bugs fixed.

Perseus Control DLL v3.2 (19 Dec. 2009 - 47 kB .zip file) Fixes issues with multiple receivers installations. Improved support  for VE3NEA's CW Skimmer v1.5. Unzip and copy in the Perseus software v2.1h folder (and in the CW Skimmer folder). Download here.

ExtIO DLL for Winrad (20 Dec 2009 - 1.6 MB .zip file) Includes the support for all the Perseus output sampling rates. Download here.

Enjoy!

Evening all, it's a pretty wet night here in the UK and with the children tucked up asleep in bed and the YL at work it seemed a pretty good idea to get some shack time in!

I’ve put together some pictures of the Perseus, QS1R and the Perseus running using the HOKA SDR interface. I have tired to keep them pretty similar on settings so you can get a look at the lay of the land as it were when it comes to the current crop of SDRs. I will say this and that is the QS1Rs SDRMAXII interface although not as polished as the Perseus GUI does has the advantage(?) of the waterfall and FFT spectrum at the same time; again the HOKA SDR also shows the two together.

It is a shame that as yet Nico has not decided to offer this feature – I am sure it is on someone’s Christmas list! As far as performance goes the HOKA SDR is in very early beta and as such does not benefit from some of the changes Nico has made to the firmware loads for the Perseus. I am sure this small issue will be corrected in a later version along with some more control over the GUI and spectrum monitoring bandwidths etc now as the native Perseus GUI has 2MHz on tap.

For all the screenshots have a look in the gallery.

Best 73 & good sDrX!

Having some late starts has its advantages when it comes to LF DXing. This morning I was not needed in the office until 9am which meant some time having a look around the MW band for some US and Canadian stations. Don’t get me wrong I am up with the birds so if there is DX about at 6am then I am there to catch it! The sprogs do not as yet understand what a laying means …

I normally like to check 1010 KHz and 1050 KHz as both are pretty strong to me on the loop, well I was rewarded well this morning, Perseus was showing very strong carriers on all the 10 KHz channels across the MW band.

CFRB and WWZN were like locals to me. Pretty amazing to think that the 1.1 meter ALA330S loop was working that well! It’s not designed for MW DXing as the gain falls off below 2 MHz but even so – the recordings I’ve made this morning show that even at 8.45am they were still very audible. Much more so that the inverted L that I have up which is swamped by locals the moment the sun rises all trace of TADX more or less vanishes, whereas the loop is still going strong. That is one area that the wideband antenna and the Perseus are made for each other – showing the 2 MHz of the LF end of the spectrum at one time in waterfall mode allows you to spot the TADX a mile off.

With this in mind and what it seems a new aspect to my Perseus listening I have decided that father Christmas is bringing me something better for TADX – the ALA100 – this large aperture loop looks ideal for my QTH and would allow some lower frequencies to be DX’ed a little better. The ALA330S is great for UTEs higher up and to some extent the LF bands and the inverted L works very well all over, but the reviews of the ALA100 make it very tempting. I know what I will be doing on the 25th December this year! With the turkey in the oven cooking away I will be running some more RG58/U down the bottom of the garden to my new toy.

The TADX mp3 recordings are below; they were made at 8.43am and 8.45am. Most remarkable from my modest setup considering it was pretty much daylight by then.

Not being a huge TADXer I recently had the opportunity to have a few late nights (or is that early mornings) which gave me the time and the band conditions to try some TADX. Going back in time I used to spend many late nights armed with my Kenwood R2000 and shortwave magazine looking for these elusive TA stations which “popped” up for everybody all the time it seemed! From the logs I could see that WINS on 1010 kHz and CJYQ on 930 kHz should be simple catches with my “DX” setup! Back then I knew that you needed an outside aerial and an ATU … That was it! TADX only happened at night and that it needed to be the depth of winter before you would hear anything. Fast forward and with the improvement in receivers, aerials and knowledge the TADX season seems longer and a lot more can be heard – if you spend enough time in headphones replaying that toth identification over and over.

It’s pretty easy with the Internet to get an idea of how well flags, pennants and beverages work for TADX and I must admit I am in awe of some of the logs and recordings I hear from people in QRM/QRN quieter parts of the UK and EU. Ken and David (Ken a big Perseus lover) I salute your logs! A true inspiration; to anyone who wants to try out TADX. And that is me included!

So what have I done then? Armed with my trusty 1.1 meter Wellbrook loop and Perseus I hit the medium wave band in the early hours. A quick scan of the 10 kHz channels in waterfall mode allows you to see the TADX carrier’s in-between the UKs 9 kHz spaced stations. A wondrous sight as they are pretty much inaudible but very visible on the waterfall. A godsend; no doubt to serious TADXers.

I’ve uploaded a few stations which I know to true TADXers are regarded as “easys” but for my 1.1 meter loop I am pretty impressed!

My logs for the night include:

880   WCBS New York
920   CKNX Wingham
1010 WINS New York (very deep fades over the 1/2hr I was listening)
1010 CFRB Toronto
1030 WBZ Boston
1050 WEPN New York
1200 CFGO Ottowa
1320 CJMR Mississauga
1390 WEGP Talk Radio (could have been a local at one point)
1430 WENE Endicott
1430 CHKT Toronto
1470 WLAM Lewiston
1500 WFED Washington
1510 WWZN Boston
1520 WWKB Buffalo
1700 KVNS Brownsville
