Re: Traffic Hording?
¿ªÔÆÌåÓýHello Patrick, The station in question is KW7JOE. He broadcasts every 5 minutes Packet #1 is a standard info beacon with a position.? That really should happen no quicker than every 10 minutes and realistically, can come far less often.. say every 30min.? Packet #2 is the the beginning of a set of telemetry packets.? Consider these the column titles for the rest of the telemetry data.? Packet #3 are the units for those columns.? The rest is the various data.? The more often you send it, the more resolution you have in the data but one needs to question do they need that much resolution.? I would argue NO.? You can see a graphical depiction of that data here:?? Btw.. if this location is correct.. it seems that the INDMT node has some decent elevation which helps in all respects for distance, more packet decodes, etc. ??? The problem is that the station that is 60 miles away is getting the traffic via our digipeater vs my iGate which is 15 miles away. As other have described, it shouldn't really be a "competition" but I understand your perspective.? Two things I should have mentioned before: ?? - I've found that Direwolf isn't the faster decoder.? I bet with disabling the FIX_BITS option, that might speed things up a little ?? - A Raspberry Pi isn't the fastest computer either.? You could throw more CPU power at it and it might help but you have to question why it would matter ?? - What is your Internet connection like?? Very generally speaking, the faster it is.. the lower the serialization delays thus "lower the ping times".? If you're looking to get to the APRS-IS network the fastest, every little bit helps ??? Regarding APRS on 440, I'll have to start a new topic on that. I didn't realize it wasn't that common on 440, so it may not be worth looking into. Really I hadn't given it much thought other than, "Maybe people might like some 440 coverage?", and good to know on the tuning. I'll be sure to get with another operator I know that has some bench equipment for proper tuning, if and when I do it. I don't know if there are any "packet clubs" in your area of Idaho but if there is, you might see if there is much interest or if it's been tried before.? I'm not saying there isn't a benefit here but the propogation of 2m is far better than 70cm.? Instead, maybe consider setting up a packet BBS with some cool features like CONVERS chat, WW messaging, etc. ??? I am constantly doing updates and tuning on the iGate but the digipeater is off the grid. I do think we're going to have to go pull it, do some more tuning and updates this summer but it's best that I know what I need to do now before I actually go grab it. If the digipeater is off grid (no internet), there is very little risk.? If it works.. don't touch it. ??? I am curious if you have a list of recommended hardening? I know a couple thing I do is noatime, nodtime, enabling more memory pressure and there's another app I use that pre-loads common applications into memory to reduce SD card writes. On my desktop it's almost reduced writes to nothing. Every time I do a trim, it trims 0 unless I've been deleting files. Section 6 - 11 for sure:? ??? No duplexers, no filters, any suggestions? If I can keep the signals clean, I'm game! Not always required for "quiet sites but it can help your radio with avoiding being swamped by nearby signals, etc.? Look on Ebay and other sites for say a 4 cavity 2m duplexer set.? They aren't cheap though. ??? TXDELAY 15 believe it or not was working, at least locally, but I went ahead and set it back to 20 to be safe. This is only important for TRANSMITTING so it won't help your receive "performance" ??? I can shoot the other station a email to let him know but I doubt a beacon every 5 minutes isn't deliberate, he's likely transmitting it for his own logs though it's getting 60+ miles out. --David KI6ZHD |
