HOPE OSCAR 68

Hi all.

tonight I caught the telemetry beacon of ham radio satellite HO 68.

HO-68 telemetry cw signal. Analysed with SA free. Click to enlarge.

My setup:

RTLSDR
TV satellite amplifier 40-2400MHz
Seven element yagi antenna for 70cm band, 30° elevation, about 160° azimut, under roof
HDSDR

I'm waiting for more amateur satellite signals to come...

RTLSDR: rtl_power - another example

Hello,

yesterday I used rtl_power to create another heatmap. It covers the frequency range from 3 MHz to 5 Mhz.

Have a look at here, please:

As you can see there are many stations that come an go again. Ham radio stations, BC stations, Stanag 4285 and many more...

RTLSDR: rtl_power

Hi.

There's a new utility in the famous RTLSDR package: rtl_power. Coder keenerd says about it:

Rtl_power is a small CLI tool for logging wide swaths of bandwidth. You can specify any chunk of spectrum, with any FFT bin size and any logging rate. (For sane values of any.)

I've done a hf scan with rtl_power lately. It shows a spectrum graphic from 3MHz to about 15MHz.

You can see it here:

Attention: it's a big picture! ;)

You can see many bc stations that come and go. OTHR are visible, too. And many other stations.

My setup was a DVB-Tstick modified as direct sampler. I connected my 12m wire to it.

It's a very cheat solution for non realtime / longterm hf band observations. But you can also use it with a unmodified DVB-T stick, too.

And now have some fun with rtl_power :)
