I was checking out UI View 32 tonight on my way home, and saw you driving near Covina... very cool...
Is there a way for me to send a message to you, or to any other stations I want to contact ?
In order to beacon automatically go to the Setup, Station Setup, menu item
Ensure the Unproto path is APRS,WIDE1-1 or APRS,WIDE2-2 For southern california area these paths will ensure you get to an Igate which will allow your information to get to the Internet APRS infrastructure that will do a lot for you. Remember to keep paths as short as possible. I generally run APRS,WIDE1-1. In your beacon comment you can put in your Name or any other information you may want, Again you want to be short and descriptive.
In the Beacon Intervals going left to right, the first box is your standard beacon rate it should be more than 30 and I think that 60 or even 120 would be better.
The next box is your Mobile rate, this is the rate used when valid GPS data is being received. Try to stay away from an excessive beacon rate especially of you are going slow. 1 -2 minutes is fine for testing and learning, but that rate would be frowned upon. Ideally a rate of greater than 3 minutes is much preferred on this limited resource. 10-15 minutes even better.
The third box is your distance beacon, this will transmit if you position has changed more than the value of the mileage you type in the box.if set to three miles it would transmit a new location if it is more than three miles as the crow flies from your previous position transmitted.
If you press the F1 key it will give you context sensitive help for the menu you are adjusting. Here are some of the more relevant items related to this discussion.
Unproto address - the unproto address used for your beacons. It consists of a destination address and optional digipeaters. The default is a destination address of "APRS" and no digipeaters. If you want to include digipeaters, then use commas as separators. E.g. "APRS,RELAY,WIDE" will send your beacon to APRS via RELAY and WIDE. See UI-View32 Destination Address for information about how UI-View32 regards "APRS" as a special address.
If "Unproto address" is left blank, then it will be defaulted to "APRS".
Beacon comment - The comment text at the end of your station beacon. NOTE - if longitude and latitude are left blank, then the beacon consist only of the comment. This allows you to send an APRS compatible locator beacon by putting the locator in the comment in an APRS compatible format. E.g. ">IO92XX/- Roger in Boston", or "[IO92XX] Roger in Boston". Please don't make the comment too long! UI-View32 will warn you if the comment exceeds the 43 characters allowed in the APRS specification.
Add Ui-View Tag - If this box is checked, then a tag showing that you are using UI-View(32), and what version you are using, is appended to your beacon. The format of the tag ie e.g. {UIV32}. The numbers will change according to the version. UI-View32 identifies stations that send the tag by marking them with a '+' in the Station List, and using different colours for their callsign labels. Don't turn off this option unless you have a good reason, because other users' UI-View(32) systems use the tag as a way of telling that you are using UI-View(32).
Beacon interval (Fixed) - The interval in minutes at which your station beacon is transmitted. An interval of "0" disables the beacon. DON'T set an interval that is unnecessarily short! 30 minutes should be ok for most uses.
Beacon interval (Mobile) - if you have a GPS attached to UI-View32 - see Using A GPS - then UI-View32 will automatically go into mobile mode when it detects valid GPS data. The frequency of the mobile beacon is determined as follows:-
· The interval between beacons is never greater than the value put into the minutes box. (Putting '0' disables the mobile beacon.)
· If the miles/km box contains a value other than '0', then UI-View32 constantly calculates the distance travelled since the last beacon, and sends a beacon when the specified distance has been covered. This means that your beacon frequency will automatically vary according to your speed.
