HRWB077-Hamvention 2019 Wrap Up May 21, 2019

Show notes

George, Brittany, and Jeremy just returned from Hamvention 2019 in Xenia, OH. We had a record year this year - there was no shortage of folks who stopped by to say hello and to pick up our build projects! In fact, we were so busy that we didn't get our usual level of coverage this year. A big THANK YOU to everyone who stopped by to say hello and support us. A special big thanks to the guy who bought my go box!

We interview Eric from Elecraft on the new K4 Direct Sampling SDR HF Transceiver, Mike from Flex Radio on the new multiFlex feature, and Kaitlyn from Digilent on the new Analog Discovery Studio. We also include Hans Summer's presentation from FDIM.
