Welcome to the S.H.B.R.G. WebSDR receiver, located in JO21PR, 's-Hertogenbosch, Hogeslagen.

View from PI2SHB, in the distance PI1SHB and PI6SHB.

S.H.B.R.G. stands for 's-Hertogenbosch Repeater Group, we are part of the VERON A25.
For information about S.H.B.R.G, please have a look at https://shbbg.wordpress.com.

The receivers are 3 times RTL-USB Stick's and 2 SDRPlay RSP1A.
The RSP1A for 2 meters is modified and is using an externel clock signal from a GPSDO unit.
The same for RTL-USB stick and LNB for 10 GHz.
Both are modified too, using an external clock reference from a GPSDO unit..

23-10-2020: A makeover of our websdr, Thanks to Steijn for his big effort to help us to make this possible.
22-08-2020: The Antenna for 433-435 Band was change to a X300 instead of the SG7900, the performance is way.. way.. better.
Thanks to PD1ANF and PD9BG for supplying the X300.

31-07-2020: We did maintance today, improved stability for the 2 meters RSP1A.
The RSP1A didn't lock allways to the external refence of 24 MHz.
25-07-2020: We modified the RSP1A, now it is using external reference of 24 MHz, GPSDO locked.

We got our self a domain, the new url is http://sdr.shbrg.nl:8074 The other url http://sdr.pi2shb.ampr.org is still active too.

Since April 2018, the Chrome browser is reluctant to play audio on WebSDR sites. If you use Chrome and have no audio
on WebSDR sites, a workaround is to switch off Chrome's new autoplay policy, by typing
in the navigation bar and changing this setting from to (and restarting the browser).
The second option is, use the "Chrome audio start" button below.
