The next issue of @makemagazine has a really great piece by Tim Deagan on #SoftwareDefinedRadio, and while proofing it the other day, I learned that I could use my existing #RTLSDR dongle with my phone, which opens up a whole new, ultra-portable #SDR world! Anyone else playing with a setup like this? Antenna recommendations? 
@w8emv@a2mi.socialAn #Airspy HF+ and a #Youloop antenna is very portable, and gets you very broad frequency receive coverage.
#Nooelec has some fun SDR parts too.
The ARROW club is doing a group build of a "tape measure Yagi" antenna, optimized for 2 meters and very directional. That's a transmit and a receive antenna, and when I get it built I hope to take to to the top of a parking structure and point it at repeaters far away.
