Hey folks, just want to note that, for whatever reason, there are simply no more data points to digest. I have heard absolutely zilch (except a few key clicks) since last Monday (July 29th, I think). I am not sure, because I haven't listened all day everyday for the entire period since I first heard these folks about 5 years ago (I only listened sporadically, initially; it was more of a nuisance to me back then as I was trying to find other stuff and my gear kept stopping on this system when either searching in normal mode or in the SigStalker mode) but this seems like the longest continuous stretch of no activity from these folks in my memory. Recently, I started listening around there again and these folks were almost a daily occurrence (for about a couple of weeks or so) and, after I saw another posting for an unknown I just felt it was the right time to bring it up as a thread on this site - aaannnd, of course they go quiet just about the same time I do that!;-( ....figures!
In the past, on those occasions when I felt like listening for them, I did notice they would be pretty sporadic in their usage as I noted in my first posting on this in this thread. However, this latest spell does seem unusually long based on my past experience. Could be any reason and I don't want to get weird and "conspiratorial" about it; maybe they are on a vacation and will return when the man goes back to work (a lot of the traffic I have heard, as mentioned before, seems to be between the two of them right after he gets off work) or he may have retired and so has stopped using the system completely or they have moved locations or...who knows? All I can say is there has been not a peep from them in over a week now while they used to nearly "shake my shack" with their transmissions!
Sorry it's such a dud to all of you who may be interested - maybe they will return or maybe not, I cannot say, obviously. So, until there is more data to digest this will remain a mystery, perhaps forever unsolved.
BTW, to the poster who mentioned Palomar - I usually do not receive the Palomar repeaters at all on my Signal Stalker equipment, and in normal operation those repeaters, while of reasonable strength relative to me, are nothing like what I hear when these folks key up! As a point of reference, I do, occasionally, hear mobile ham users on the 2 meter band on the INPUT of the Palomar repeaters (and in simplex mode, of course) on the SS (Signal Stalker) modes but not usually the output when they are within range (I can see a fair portion of 78 from where I am and that part of Oceanside).
Anyway, all for now - thanks for the interest and attention, folks, and interesting speculation, but, for now at least, it appears the system has gone dark and the trail has gone cold. I'll revitalize this thread if and/or when I have anything else to report.
