Noise Study

So perhaps you read FCC Technological Advisory Council is initiating a noise floor inquiry   That is something probably long overdue in my opinion.

I have often wanted to map the bad areas around town.  Seems a Raspberry Pi computer with a RTL-SDR stick and a USB GPS could the basis of sampling the noise floor on various bands and logging that and the location.

And then a way to download this and overlay it on a map when you get home.

Seems like a good SDR project for someone.  I kind of wish I knew how to do it myself.

Maxtrac's and such.

Maxtrac programming software for Linux/ Linux software for programming Motorola Maxtrac radios through a serial port:

I love this, as the Maxtrac/Radius line is my favorite radio.  No longer need DosBox.

Speaking of that line of radios.  Here is well documented, channel (40 channels) steering a GM300 for a remote base:  https://www.youtube.com/watch?v=ZY9pfy5F4hw

I have to say Skyler, KD0WHB is an amazing young kid with a lot of enthusiasm in the right areas. 

On that DIY topic, I recently watched DX Engineering video where they interview the new ARRL CEO, Tom, NY2RF.  Tom says If you want to forecast the future, you have to invent the future..." agreed!
