I'm not sure that I understand that, but it probably doesn't matter. > I didn't realize a WIDEn-N would respond the the WIDE1-1 in that > manner. That is an important part of how WIDEn-N digis work. If they didn't respond to WIDE1-1, and the mobile station didn't hit a fill-in digi, their beacon wouldn't be digipeated at all. > The intent here is only to get the low power, low antenna HT signal > out.

In that case, I would set a path of N7FMH-9,WIDE2-2 in the HT, sorta like Michael's suggestion. You would have to have DIGI ON in the T2 for this to work. > But if the only RF path is through two WIDE1-1 digipeaters, how do you > accomplish that? This would / should never happen. Think of the havoc if you had more than one WIDE1-1 anywhere in your path. The purpose of a fill-in WIDE1-1 digi is to help get you go a high WIDEn-N digi. If you attempted to get through two fill-in digis by using a path of WIDE1-1,WIDE1-1 (evil) you would sometimes be hitting a WIDEn-N digi direct, and it would be triggering every fill-in digi out to the horizon as well as the WIDEn-N digis around it. If WIDE1-1,WIDE1-1 is evil, just think how much worse it would be if a few more were thrown in!!! > Normally one would not use WIDE1-2,WIDE2-1 for the stupid/abusive > reasoning, but would that get through two WIDE1-1 digipeaters?

Only a WIDEn-N digi (or one that specifically had an alias of WIDE2-1) would respond to it. The question comes down to the WIDE1-2. I presume that a fill-in digi would respond to it and kick it out the other side as WIDE1-1 still available, but so would a WIDEn-N digi. > For the WIDE1-1, they are now: > USEALIAS 1:ON > ALIAS 1:WIDE1 > HOPLIMIT 1:1 > DIGIID 1:ON > DUPETIME 30 That all looks OK for a fill-in digi. > I thought it would be interesting to collect data from a 'timed' > tracked and overlay it on a SmartBeaconing track.

I don't think it would really prove a lot. The HT (going through the T2) would be basically a 40W tracker with fixed timing. > I also want to run different SmartBeaconing profiles over the same > tracks for comparison.

I suppose you could vary the slow / fast speeds and the slow / fast timing, but SmartBeaconing takes care of itself. Decide on a slow speed and a slow rate. Decide on a fast speed (usually your fastest highway speed) and a fast rate... i.e. decide on a fast rate of 1 to 3 minutes or so. I use 1 minute, but I can't drive more than a couple of minutes at my fast rate at any given time because there are very few straight roads here (an island) and most the 80 kmh sections are pretty short. For someone that did lots of commuting near a large city (APRS frequency busy) or lots of cross-country trips, I would recommend more like 2-3 (or even 5) minutes for the fast rate. Corner pegging will take care of the rest. > From PNRDVL to just east of W1CNH-5 in the circular mountain range. It > is a really old extinct volcano I believe. I'll be watching! Good luck with the experimenting. 73 es cul - Keith VE7GDH -- "I may be lost, but I know exactly where I am!"
