Ultimate2 QRSS kit by Hans Summers G0UPL

The ultimate QRSS Transmitter Kit is a new version of the  original Ultimate QRSS kit. This new version comes with a pre-assembled AD9850 DDS module, and plug-in low pass filter modules which are also available separately for any band. The kit can transmit on any frequency from audio (500Hz) to over 40MHz, and changing bands is a matter of plugging in the appropriate low pass filter kit to attenuate unwanted harmonic output.

I've just completed the kit and put in on air, these are some photos:

Where is going my WSPR signal Today

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.

Work conditions:

Ft817
Doublet antenna for 20 meters
WSPR software
Cat interface

I'm working with a Mac OSX computer, in a Windows XP vmware virtual machine.
