Assorted ramblings from the developer


RadFxSat Fox 1B

Picking up RadFxSat Fox 1B on her first pass over Cornwall, FM on 145.960 adjusted for Doppler. The initial TLE data is pretty accurate. Receiver is the Airspy HF+, antenna general log periodic for 130 MHz to 1.3 GHz.

V3 Analyser

Here's a screenshot of the version 3 Analyser slowly taking shape. This is a zoomed processing on 963kHz taken from an overnight recording, we see many medium wave (MW) carriers present.

Data processing at 1,343 megabytes / second from a NVMe SSD card.

More later...


Pirates!
Pirates!

Listening to pirates on FLTSAT-8 with the HF+. Found the FLTSAT 8 TLE data on the internet, added it and let the software point the log periodic at the satellite. First time I've ever listened to the pirates - not very entertaining if truth be told.

Airspy HF+ & NOAA 18

Overhead Pass

Here's an example of the HF+ receiving the NOAA 18 APT weather satellite, the antenna is a log periodic covering 130 MHz to 1.3 GHz. The HF+ is very sensitive and very quiet - no mixer products, spurs, or artifacts at all.

    

    

Low Angle Pass

Here's an image from NOAA 18 but a moch lower angle - 13 degrees. You see noise on the image, but nethertheless an excellent copy.


Another Airspy HF+

My second Airspy HF+ arrived today fresh from the production run, below are a couple of screenshots from BBC Radio Cornwall on 103.9 MHz. In the main photo you see the packaging!

Well worth waiting for, no-one will be disappointed.


CW Skimmer

The original CW Skimmer implementation missed an importrant feature, namely:

* Working properly

After a few hours' coding it's now OK.


ACOM 1200s

This is what I want for Christmas. 1kW of pure loveliness, ideal for my SDR transceivers.

New Wesbsite - Almost Ready
New Wesbsite - Almost Ready

The new website (that's this one) is almost ready - still testing but looking good. Sadly the old skins I used on DNN8 were deemed to not be secure, the company I purchased them from did nothing about this, so I bought news skines from Mandeeps.com and a new DNN system with DNN 9 was installed on a big DoDaddy farm.

Please have a look through the pages and report any problems.

Thanks - Simon
