9Z4Z This is a WebSDR receiver, located in D'Abadie, Trinidad and Tobago.

One 20ft mast holds an EdFong DBJ1 Dual Band antenna and a homemade ZS6BKW Dipole.

There are 7 RTL-SDR.com V3 dongles connected, but only the first 4 seem to be functioning. Troubleshooting is ongoing.

Try the Mobile Version of this page for simple controls. I use the mobile version most often on my cellphone and Amazon Fire Stick.

Zoom in to the waterfall on the HF bands to see/hear more activity.

The server is currently running on a Debian 9 Workstation.
It is operated by Gisele, e-mail 9z4z@bengman.com.
