Seeing over 50 HID's per hour (Counting dupes this is as many as 200 per hour), this is an abomination on 144.39 just in my area. This is a BIG problem that we need to fix now. HID ON causes a TNC to send out an ID packet once every 10 minutes. This is NOT an APRS function and is NOT desired on APRS. From the beginning APRSdos and other software makes sure to initialize the TNC's with HID OFF. Apparently newer software has not been doing this and now MOST TNC's on the air have HID ON and it is DOUBLING if not TRIPPLING the load on 144.39 with USELESS packets. I ask again for stations that are finding their HID's ON to help us figure out what software is not properly configuring the TNC's. The following is the status of APRS softwware and HID: APRSdos sets HID OFF during TNC INIT. WinAPRS ??? APRS+SA ??? UIview ??? Xastir ??? Are there any WEB pages that are recommending DIGI's set HID ON? If so, lets get those web pages fixed too! We must squash this bug. Every TNC that has HID ON (every 10 minutes) is loading the channel equivalent to THREE other stations (with HID off) and sending a position packet only. Every properly configured DIGI that is sending HID ON is TRIPPLING the load from digis. SO far, I am seeing MOST stations with it ON. This is something SIGNIFICANT that we can fix. Lets fix it. Bob
