If you’re looking for a way to listen to some HF activity, but don’t currently have an HF radio or maybe you’re lacking an antenna or live in an area with a heavy noise level – you can try using WebSDR to receive. http://www.websdr.org has a bunch of receivers on air that are broadcast over the internet, including one in Northern PA that’s great to listen to NY State/Section and Regional nets with. Examples being the New York Public Operations Net at 5PM daily on 3925 kHz or Second Region Net (2RN) at 6:30PM daily on 3926 kHz.
