Sending messages without RF


 

开云体育

Morning,
I was wanting to send messages via the internet and I am not connected via RF, what’s the beast path to do so in making sure it goes from internet to RF? This is the home station and its just set up to monitor the aprsis server.
?
Any help would be great.
?
Thanks,

You will first need to have an APRS-IS server passcode for your callsign, so you can connect to the Internet backbone with permission to transmit packets to the backbone.

There is no way at all to guarantee your Internet packets will get to RF. First off, only text message packets that are addressed to RF stations within range of an I-gate will be forwarded through only the relevant in-range I-gates (plus your next position packet, so the RF recipient knows where the station that sent the text message is located). Secondly, that requires an RF-transmit-capable I-gate within range of your target RF station; there are few of those, due to legal constraints and concerns in different jurisdictions on automatically forwarding packets from the Internet.

There is no way whatsoever to blast your packets to RF over the whole planet. The APRS-IS backbone network and I-gate software are specifically designed to avoid that sort of behavior, since the local RF network is intended for _local_ tactical information (not irrelevant spurious data from out-of-area stations), and the VHF channel doesn't have the bandwidth for the entire planet's worth of APRS stations. If you want to reach the whole planet on RF, you'll need to use the 30-meter HF band on RF yourself (and that has even less total bandwidth than the local VHF channel).

Andrew,
Yep connected to the noam.aprs2.net aprsis server with password as I get the reports coming in from the net. I was curious as to drop down I have is TEMP1-1, TEMP2-2, WIDE1-1, WIDE1-1, WIDE2-2, ARISS, SGATE,WIDE2-1 and OUTNET Just curious as to which one I need to help that along and yes I do know that it may not get through with the path being from the aprsis servers if the RX station is not within range of a digi or the like.
?
Thanks,

Digipeat paths are irrelevant when relaying through the backbone. Each transmit-capable I-gate makes its own decision as to what digipeat path will be used for forwarded-from-Internet packets; most choose no digipeat path at all so that only RF stations directly reachable by the I-gate will hear the transmitted packets. And the original digipeat path is buried in the 3rd-party header of the packet body, so will never be processed by digipeaters after the I-gate returns it to RF.
