Really don’t want to stop logging messages lol, but I suppose its time to start making notes. Once I can get this running on the RPi ill leave it logging 24/7 for a while so I can analyse the data. Still lots of data being sent that shouldn’t be, names, phone numbers, address information, IP addresses, email addresses, URLs … and I’m sure if I log for long enough the obligatory username and password.

So I can’t show or share any of the data I’m collecting. Hibby just pointed me to (Legal stuff) … even though I can’t share the data I can show you how to demodulate the signals yourself.

Random picture for today …
Since I’m working on radio stuff here’s my baofeng handset its the uv-5r, a great starting handset for people looking to get in to HAM radio and start learning. I bought one relatively cheap on ebay around £20, before I got my licence so I could scan and listen a little. I’ve some other scanners and sets but ill save those for another day.

A few pages of notes written and a rough idea for an introduction to SDR. Time for a brew and to record / talk through the audio. Will report back in a while.

Hakology Day 8 : Blog Entry

Posted ebay stuff, bills to pay, boring stuff. Couple of support calls to make. Will be on soon though.

The amount of profit water, gas, and electricity companies make you’d think they’d have more people staffing the phones. Especially when everyone uses mobiles these days. I hate online payment services much prefer top up cards or direct payment. Finally got through and turns out I’m ahead with my payments whoot whoot. Only one more call to make.

Finally done with all the menial stuff. Time to get busy.
