Software / WSPR?
« on: June 03, 2021, 0230 UTC »
Has anyone messed around w/WSPR on their SDRs?  Thought it might be a useful tool for monitoring real world propagation at my QTH.

Would be neat if Multimode added it…(nudges Chris… :))

Think i could see the carrier last night, but i've got a lot of QRM around there so can't be sure.  Wasn't able to make out any audio.

SDR - Software Defined Radio / RPi Ethernet question
« on: June 21, 2020, 0338 UTC »
So if I’m connecting a device with a static IP directly to my RPi via Ethernet, any speculation why it wouldn’t be detected?  I know the cable is good, I know the Ethernet is good (I can ssh into the RPi from my mac), and I know the device is fine (i can ping it from my macs Ethernet port).  There’s something about the damn RPi configuration that’s just not meshing...I even checked that the device and the RPi have the same subnet mask.
Any ideas?
