Become an expert operator of KiwiSDR and WebSDR receivers.
K3FEF is now running an rx-888 with NovaSDR! Listen for some synchronously demodulated Brother Stair, tuned on the K3FEF NovaSDR.

While making a routine visit to see the latest list of NovaSDR / PhantomSDR sites, I was pleasantly surprised to see that the K3FEF WebSDR was being upgraded with the addition of an RX-888 mkII direct sampling SDR. It is significant, as this is new radio, in Milford, Pennsylvania, will support the first NovaSDR site in the northeastern USA and the second in North America.

I have been a frequent visitor to the K3FEF WebSDR and enjoyed listening to mediumwave AM talk radio stations in the New York area. Milford is far enough west of NYC that the stations are strong, but not clobbering the SDR, so plenty of other stations from the region are an easy catch. Reception is super clear on the built-in synchronous demodulator.

The older WebSDR lashup at K3FEF had some limitations, as it used a group of SDR dongles, with non-continuous coverage of the bands. Ham bands were in, but a lot of maritime and aero frequencies were excluded. Now, with their new broadband direct sampling rig, a visitor to the K3FEF SDRs may listen for signals on any frequency.

The first NovaSDR site in North America is the Lumpkin Schools SDR of Dahlonega, Georgia, which also runs an RX-888 mkII receiver. That one also does great on mediumwave, plus sensitive reception on other bands through 30 MHz.

These NovaSDR sites are great for people who tune in AM radio and shortwave broadcasts via internet SDRs because they work great and are less restrictive than KiwiSDRs.

It seems that a lot of KiwiSDR site admins do gatekeeping, where users must give a name or callsign before the site can fully function. Some will even ban a user who won't comply. And then there are the sites where operators have set short inactivity timeouts, as brief as 20 minutes. Let's not even go into the issue of blocked frequencies, or else I might rant for another thousand words...

The bottom line is a new NovaSDR site is up, offering internet SDR listeners high performance and features from VLF through HF, thanks to K3FEF.
