Greetings all:
When Garry notified me that SIW was transmitting on the intended schedule, I setup for an overnight session
to see how well I could copy all 3 transmission modes.. I was not disappointed, and propagation cooperated..
I used SpecLab for capturing, and feeding audio to OPERA.. and WSPR-15 got audio directly from souncard..
I use the filters in SpecLab to reduce several types of noise, so WSPR-15 did not have that benefit as did OPERA..
The radio IF bandwidth was set at 500 Hz.. The dropbox image shows a decent SpecLab capture of all 3 of
the transmission modes , out of sequence, but all there in one screen..
It's amazing what 1 watt DC Input into a 15 meter antenna can do on a good night on 1750 meters..

Below is a dropbox link to a capture of my whole screen showing OPERA -WSPR-15, and SpecLab.
The SpecLab image is overlayed from a copy of the full SIW lowFER transmission sequence on 185.185 KHz ...
