    The first DMR repeater in Turin activated!
    The HAM digital communication network grows and new radio techniques (DMR ETSI
    TS 102 361-1: the DMR air interface protocol
    TS 102 361-2: the DMR voice and generic services and facilities
    TS 102 361-3: the DMR data protocol
    TS 102 361-4: the DMR trunking protocol)
    are introduced aside of the D-Star experience!

    The new repeater temporary named I1YRB (DMR call ID 222102) on the DMR-ITALIA net is active from Torino JN35UA. According to Roberto, IK1JTD that started the DMR in Piemonte @Mongardino (AT), we use the same couple of frequencies: 430.962500Mhz shift +5MHz.
    The repeater is linked to the global network (regional/national/international) via a "c-bridge" software facility.
    Usefull links:

    Many thanks to IK0YYY and IK1JTD to support this new adventure!

    New WebSDR server added
    Fighting for simple, inexpensive, low energy and networked solutions i tried to build the cheapest websdr server without quality compromise! I got this thanks to the following components and software:
    Raspberry PI (RPI) model B ARM system
    High definition audio for RPI Wolfson card to sample 192 kHz stereo @ 24 bit
    Radios through RF SoftRock sampler
    The original WebSDR software.
    The antenna is a Maxiwhip.

    Listen to rpi.ham.radio.it, tuned on variable frequencies (i.e. 14150kHz now).

    Others local WebSDR sites:
    40m websdr.ham.radio.it (only Java, not HTML5 enabled)
    80m websdr-next.ham.radio.it (WebSDR rel. 11 so HTML5 enabled)

    Access the WebSDR.org site for updated servers list.

      Simultaneous realtime spectrum view
      In this page, the spectrum acquired in Torino and Pino can be see in parallel allowing to compare signal strenght.
      In case of radio operations, the tuned frequencies may be different. So to obtain again the same view you need the access via 'Radiomonitor client' in order to align the windows.
    • 15may2010
      Web access to realtime spectrum view is available!
      The spectrum acquired can be see directly from your browser. The following locations are provided:

      due to authorization statements IR1TB must change the callsign in IR1CJ!
      The work around will take place on saturday 21. So users, to address the repeater, will have to change their radio RPT parameters.
      Furthermore some service trouble may occur on international D-Star links in the next few days.
      The sysop team apologize to you about this and hope the change will be the final one. SORRY AGAIN!

      IR1TB ALERT!
      IR1UCW repeater transmissions heard on the access frequency of IR1TB (145.9875 MHz). This can be origin of access collisions and reason of sensitivity loss and worst D-Star service quality. The problem will be faced by the IR1TB sysop team
