openSpot digital radio IP gateway / hotspot

   Jucarie interesanta.  Anuntata cu surle si trambite, promovata  destul de agresiv in mediul hamradio. Prea promovata chiar.. Desi  reclama suna bine si obtiunile sunt frumos  prezentate eu sincer prefer tot DV-mega-ul meu cu RPI 3 despre care am scris mai demult.

 Totusi , pentru cei interesati de noutati  in materie de DMR si dezinteresati de DV-mega  punem si specificatiile aici.  Au si un video interesant de prtezentare pe youtube : aici

 Ah si sa nu uit.. mi se pare a naibii de scumpa pentru ce face :)

    Supports DMR (Brandmeister, DMRplus), D-Star (DCS, REF/DPlus), System Fusion (FCS) networks. More supported networks and features will be available with new firmware releases.
    Supports cross modem modes. Talk with your C4FM radio on DMR, and with your DMR radio on System Fusion networks!
    Very easy to use, works without a computer. No additional hardware required, works out of the box. All accessories included.
    Web interface for configuration and monitoring.
    HTTP, UDP/TCP API support.
    Custom 2FSK/4FSK RF protocol support with TDMA.
    USB powered, low energy consumption, 20mW RF output.
    Runs fully embedded software written in pure C, running on an embedded real time operating system. No Linux, bulky Windows software or failing SD cards!

     Connect openSPOT easily to DMR, D-Star reflectors, C4FM/System Fusion rooms, and use your radio with excellent voice quality without sync errors
    Customize communication settings on the web interface
    Discover how digital protocols work, and connect your own apps by sending and receiving RF frames in UDP packets
    Create your own RF protocol by customizing RF modem settings, packet format, sync words (even with TDMA support)
    Use single, or separate RX/TX frequencies
    Optional erroneous packet generator module for testing other digital receivers

    State of the art hardware design

     2 CPUs running at 100 and 120MHz
    USB mass storage device bootloader for easy firmware upgrades
    4 multicolor, bright LEDs for easy real time state monitoring
    Low power usage
    Automatic recalibration

     DMR features

    Use openSPOT not only as a DMR hotspot, but as a base or mobile station with 2 timeslots simultaneously
    Timeslot repeating in base station/repeater mode
    Send and receive DMR SMS messages
    Built-in echo service
    Controllable with calls and custom short messages to preconfigured DMR IDs


Price for EU customers: €219 (including 20% VAT, excluding shipping
Price for Non-EU customers: €182.5 (excluding shipping)
Sold with 2 year warranty, including official support on the community forums.
Package contents: openSPOT, antenna, Ethernet cable, USB cable, 120V/230V USB power supply (available with EU, US, AU and UK plugs)


 Cei de la Elecraft au anuntat noul lor model :K3S 160 - 2 m*, 100-W High Performance All-Mode Transceiver

 Pentru moment pagina producatorului este in curs de update pentru acessta versiune de transceiver, totusi au aparut ceva stiri si specificatii atat pe qrznow.com cat si pe pagina oficiala a producatorului  elecraft.com


  Era si timpul sa apara. Asa cum spuneam mai demult Raspberry Pi va avea un viitor interesant in aplicatiile hamradio  mai cu seama in  SDR, D- Star, DMR, Tetra  si nu numai..

    E o platforma foarte interesanta si versatila. Trebuie doar sa ai imaginatie. Si sunt multi care au. DV Mega e un concept care se imbina perfect cu platformale Ardunio ori Raspberry PI  si prevad ca se va dezvolta foarte tare si repede. PE1PLM, Guus van Dooren a scos pe piata cateva "jucarii" interesante si se pare ca va mai scoate.

   In prezent produce :DV Dualband Radio, hotspot DV ,Raspberry PI Single band Radio hotspot , DV Raspberry PI Dual band Radio hotspot , DV GMSK modem,  si se pare ca are in plan pentru inceputul acestui  an  Dualband Radio and AMBE3000 . AMBE3000 si  PCM3500 fiind folosite la (de) codarea digital voice.
