22827Re: [aprsisce] Dual iGate: Terrestrial and ISS
- May 7, 2013Just be aware that the current APRSISCE/32 doesn't keep track of WHICH port a station was "recently heard local" for gating messages from -IS to RF, just the fact that it WAS recently heard local. So, if a message comes across the APRS-IS for a station that's on UHF, it will be transmitted on both UHF and VHF ports.
And there is also no cross-port gating supported in the current incarnation, so messages won't cross between the UHF and VHF ports.
Now, if you ran separate instances with an APRS-IS server between them, messages will only go out on the instance/port that heard the station recently local and UHF/VHF cross messages will gate to/from the APRS-IS and manage the cross-band activity properly there as well.
So, what is it you're gaining by using a single dual-ported instance?

So, in follow up to this.We are experimenting with APRS96 on UHF in the Ithaca area.http://aprs.fi/#!mt=roadmap&z=11&call=a%2FKC2ANT%2Ca%2FN2PYI-4%2Ca%2FKC2ANT-4&timerange=3600&tail=3600I ran two separate instances of APRSIS32 for this to start with, but now I have a single instance running two radio ports.You may also noticeas a stand alone UHF APRS96 Digi in the Ithaca area (same site as W2CXM-1) on a D700 with no APRSIS32 connectionSo far APRSIS32 seems to be behaving normally running both ports rather happily. It is a WIDE1-1 Digi, and a bidirectional IGate for both (not gating packets to RF, just messages) and we have N2PYI-4 gating IS traffic from our little 3 county area to RF on the UHF channel. It's an interesting experiment.I'm wondering if that is something similar to what Reed is attempting to do, a single instance and SSID running two different frequencies?AdamKC2ANT

I would appreciate hints on the best way to setup APRSISCE to receive APRS from the ISS 145.825) and receive/send from land (144.39) using one computer. I would like to do this on a single Windows XP laptop. I will add an external ham sound "card," using the internal sound card for 144.39 and external for 145.825 (without hardware TNCs). At least, that's the initial plan.
For example, should I run two instances of APRSISCE in two separate directory structures, or can one instance handle both situations? I expect I will need to run two instances of the TNC software.
Your thoughts appreciated, *especially* if you have setup a dual-port station like this. I am inexperienced with APRSISCE, so please don't assume I already know all the details. Being an old geek, I do have a lengthy computer background, although most of it is with Unix/Linux and Mac.
Thanks ... Reed K7FLY
