[Today’s run: rest day]
I don’t remember if I have written about this before.
The January QST magazine had an interesting article about using a PAL TV USB device as a general software defined radio. I bought one of the things from ebay and have been playing around with it. I think the thing cost something like $25.
I am running the software also discussed in the magazine article called SDR#. The software will demodulate AM/SSB/FM. Adjustments can be made to filter width, AGC and other stuff. And it has a way of putting stations in memories. Here I am listening to the public radio station. You can see blockish sidebands on the signal and I believe those are the digital radio second-signal. I don’t know if there is any way of demodulating that from this software.
I hooked this up to my dipole/G5RV antenna and it pulls in a lot of local FM stations and goes through the ham bands and public service radio bands too.
It definitely is colorful.
