After a long time, due to work problem, without doing any HF and QRP activity today I've been able to switch on my wspr station again.
Just for a test I've tried a transmission on 30 meters with only one watt.
The map shows the result.
Not so much!!! I'm accustomed to arrive tu USA or Australia with these power and setup, but it's only test.
Doublet antenna for 20 meters
I'm working with a Mac OSX computer, in a Windows XP vmware virtual machine.
I was monitoring the frequency of Bolzano Radio on 120.600 mhz AM with a cheap (15 €) RTL2832U SDR. As a former military pilot and now Glider pilot I'm always interested on these kind of communications.
I expected that Bolzano Radio was at 120.600 Mhz, but the RTL SDR does not receive anything!!
Fortunately the spectrum of more of 1 Mhz is also visible on SDRSharp and the trick is done:
Clearly on the screenshot it's visible that the Tower seems 10 khz off frequency.
A screen shot of some QRSS signals that I've received on September 08 2012 at 12:52Z.
Rig is a Yaesu ft817 and a simple dipole antenna.
The frequency is around 10139 Khz
The signal on the lower part of the spectrum is from G0PKT
The Martello Tower Group G0PKT operate a QRSS beacon on approximately 10,140.010KHz running 150mW from a Hans Summers QRP Labs kit to a half wave dipole located on top of the Martello Tower. This aerial has been carefully tuned to the exact frequency for optimal performance. The beacon is operational 24/7.
