<div dir="ltr"><div>Hello,</div><div> </div><div>I am looking for some opinions and guidance on the best (least annoying) way to announce one-off events such as Ham Conventions on APRS (focusing on RF). I am writing a Python thing which will be released (eventually ;-) so don't want to produce something that may cause problems in busy/active RF areas.</div>
<div> </div><div>My thought is to announce using Bulletin format while the event is far off and then switch to a posit object as it becomes 'more current'. Just prior (as mobiles are converging) the Talk-In frequency would be sent. During the event the frequency object would be rolled back as not to hog the RF Channel.</div>
<div> </div><div>I am working on the following ...</div><div> </div><div>>30 days - No Action</div><div><30 days - Hourly Announcement (:BLNx :)</div><div><14days - Half hourly Announcement</div><div><7 days - Half hourly POSIT Object</div>
<div><2 days - 20/60 Position Object</div><div>< 6 HOURS - 10/60 Position Object</div><div>< 2 Hours - 10/60 Frequency Object (with Talk-In Frequency) </div><div>Event Start + 1 Hour - 20/60 Frequency Object (with Talk-In Frequency) </div>
<div> </div><div>The timings above represent hard coded maximums (max noise rate) - users can reduce the rate and pre-announce days. </div><div> </div><div>What information would you put in the BLN packets (>7days). My thought would be to announce the name of the event and possibly a web address or email (considering the 67 char limit). Just enough for interested parties to hit Google and forward plan.</div>
<div> </div><div>Each Event will have its own path etc.</div><div> </div><div>Does this sound like a reasonable approach and a good balance between announcing an important event and RF Channel usage?</div><div> </div><div>
Given Bob's Virtual Bulletin Board idea ... should the BLN packets continue until the event starts even when the position is sent? </div><div> </div><div>I stress that this relates only to one-off events like Ham Fests and not regular club meets or NetSked (these are handled separately).</div>
<div> </div><div>Thanks in advance,</div><div> </div><div>Mike </div><div>GM1WKR</div><div>
