<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>Hi Everyone,</div><div><br></div><div>On Saturday volunteered at a 5K race to help with the communications support. While I was sitting in my car waiting for the race to begin, I thought it might be fun to turn on the APRSDroid app to see if any of the other volunteers would appear on my display. Several did, which was exciting (bear with me, I'm new to all aspects of digital radio). So, I decided to go a step further and I attempted to send a message through the application. Apparently the message did and did not get through.</div><div><br></div><div>The next day I ran into the guy who organized and ran the communications. He told me that he got the message when he linked his system to the internet, but during the race he comm's trailer was not linked to the internet, which is why he did not receive my message immediately.</div><div><br></div><div>So I'm a little confused. I can imagine a pure internet set of links (and displayed nodes), and I can imagine a set of pure radio linked nodes. I am a little confused about what seems to be a partial mix of internet or radio nodes. Could someone please explain the mechanics of this to me?</div><div><br></div><div>Thanks,</div><div>Mike Goldweber</div><div>KB3IXO<br></div></span></body></html>
