The D-STAR network checks for a valid callsign registration before allowing access. So you can&#8217;t work any D-STAR without the validated registration. It took less than 5 minutes to enter the basic required info via the web. I entered my info on a weekend, and it was working after the following business day.<\/p>\n<h4>D-STAR Gateways<\/h4>\n<p>The &#8216;gateway&#8217; function was what really got me going on D-STAR. The digital repeaters have an internet gateway function that allows for connection to remote D-STAR repeaters and &#8216;reflectors&#8217; around the world. Count me in! This is a must have capability at K6HR.<\/p>\n<p>Finding my local digital repeaters was simple, and I quickly determined which repeaters I could access. The GPS feature enables you to find the local repeaters with the press of a button from a built-in database. Pretty slick!<\/p>\n<h5>However&#8230;<\/h5>\n<p>I also quickly learned that the local D-STAR repeaters, although capable of gateway connections, do not necessarily permit them! At least, not to casual users. I can see that the best local repeater is always linked to a certain reflector. When I attempt to change the reflector, I get an error icon.<\/p>\n<p>It didn&#8217;t take long to realize it is poor etiquette to show up on a repeater and change the reflector that many folks are monitoring! Bad idea. Now what?<\/p>\n<h5>And the answer is&#8230;DVAP<\/h5>\n<p>No Problem. I just need to be a D-STAR Gateway!<\/p>\n<p>There&#8217;s a gizmo for that! What I need is a Digital Voice Access Point or DVAP. The DVAP is an internet gateway interface that can be accessed via UHF simplex. Through the DVAP, I will have my own D-STAR gateway functionality. I wouldn&#8217;t rule out a full blown D-STAR repeater sometime in the future, but for now the simplex UHF DVAP will get the job done.<\/p>\n<p>Enter the <a href=\"https:\/\/www.hamradio.com\/detail.cfm?pid=H0-015993\" target=\"_blank\" rel=\"noopener\">ZUMSpot<\/a>.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1829\" src=\"http:\/\/k6hr.com\/wp-content\/uploads\/2018\/08\/zumspot.jpg\" alt=\"\" width=\"320\" height=\"240\"><\/p>\n<h4><strong>ZUMspot Kit Features:<\/strong><\/h4>\n<ul>\n<li>High performance 32-bit ARM processor<\/li>\n<li>ZUMspot Board Fully Assembled And Tested<\/li>\n<li>Supports DMR, P-25, D-Star, System Fusion and NXDN<\/li>\n<li>Onboard LEDs to show status (Tx, Rx, PTT, Mode)<\/li>\n<li>Up to 10mW RF power<\/li>\n<li>SMA antenna connector, UHF antenna included<\/li>\n<li>Mounts cleanly on all current Raspberry Pi\u2019s including the Pi Zero WH<\/li>\n<li>Works on ODROID boards<\/li>\n<li>The firmware is pre-loaded and is easily upgraded via software.<\/li>\n<li>Connections for Nextion LCD display and I2C displays<\/li>\n<li>1 Year Warranty<\/li>\n<li>Open source firmware (MMDVM) and board design<\/li>\n<li>Open source 3D printable case available<\/li>\n<li>144 MHz, 220MHz and 900MHz versions to be released at a later date<\/li>\n<\/ul>\n<p>I am very pleased with the D-STAR Kenwood TH-D74A, and with the overall D-STAR experience thus far, although I am still learning the radio and studying the manual.
