| This one has SDRs running KiwiSDR, OpenWebRX, as well as
| WebSDR. I like KiwiSDR's interface the best overall, but
| OpenWebRX has better digital mode plugins pre-installed on most
| of the entries.

| Set it to 4625 USB and listen to the creepy Russian Buzzer

| lost credence more recently. I also didn't notice any mention of
| it in David E. Hoffman's book, but no matter what it's actually
| for it is interesting and just a bit unsettling, especially late
| at night.

|
| Also try 7.050 to 7.300 and set to LSB.

| Comment was about amateur radio
| (https://en.wikipedia.org/wiki/Amateur_radio) and more
| particularly about contests
| (https://en.wikipedia.org/wiki/Contesting). The WebSDR
| receiver posted by the OP allows reception on 0-30 MHz range,
| which includes a number of amateur radio bands.

| For anyone else who isn't sure what this is, from websdr.org:
|
| "A WebSDR is a Software-Defined Radio receiver connected to the
| internet, allowing many listeners to listen and tune it
| simultaneously. SDR technology makes it possible that all
| listeners tune independently, and thus listen to different
| signals; this is in contrast to the many classical receivers that
| are already available via the internet."
