My biggest frustration is trying to find software and get it to work right on a Mac.
All I have at the moment is a RTL-SDR so mostly I am using different KiwiSDRs via the internet. Keeps me going.
There are two SDR apps for the RTL-SDR in the Mac App Store.
(disclaimer: I am the developer of one of them. If you have posted in this forum and want a Free promo code to beta test my macOS rtl-tcp SDR app, contact me via the email address on my website).
