Hello Walter (DJ2LF, to avoid confusion),

just an idea: is it possible to insert a steady carrier (10 sec. or so)
every 1 or 2 minutes. That could make it easier to tune into the signal.
As you mention the PSK signal has a 10 Hz bandwidth, what means that the
power is "smeared" over this 10 Hz and the weak PSK signal is
difficult to detect with ARGO.

Dear Walter,
          thanks for the screenshot. At what time did you take it? The modulator and the software was built by Markus, DF6NM, and installed at about 22utc yesterday evening. I think the weak signal cannot be DI2AG, because it should be seen exactly at the ref. sig. and the bandwidth is about +/- 10Hz.
Thanks for testing, Walter.

Walter,

 

 

 

Is this is you about 1.5 Hz high ?

Too weak to decode on PSK 31.

Dear friends,

          DI2AG on 440.044KHz is now transmitting in PSK31 with 0.4W ERP. Your reports are appreciated.
