I remember in the UO-14 days many late night passes, where I ended up talking to myself for an entire pass. If I got lucky, one or two others would show up and we'd have a ragchew for the entire pass (with long breaks for those breaking in). The biggest problems I've heard on the FM birds down this way are (1) long range cordless phones, there seems to be millions of these things in SE Asia - I'm assuming it's phones by the tempo of the speech, and (2) new operators who don't realise they're not hearing the 70cm downlinks on their vertical antennas, and accidentally stomp on the uplink. Unfortunately, due to the large distances here, there's often no one else within their simplex range to give them pointers. I have personally elmered a couple who I did find within simplex range, and got them on the birds successfully. I'm not so active on the satellites these days, but that's due to subtle lifestyle factors that brings the short passes at differing times of day into conflict with other things that happen here, rather than anything fundamental about the sats themselves. One of the things I notice here is that not only is the population density much lower, but there's none of the grid chasing down here. We do have satellite awards, but these can be completed with a modest amount of contacts (VK0 can be a challenge to work - it's the only VK call area I haven't worked). I've never understood the rationale behind increasing the pressure on an already limited resource by encouraging grid square chasing. One would have thought the FM birds should be the "WARC bands" of the satellite world. Keep the grid chasing to SSB/CW, where more operators can be supported (and maybe encourage a few to upgrade to SSB :) ). >I spent most of last year in Papua New Guinea (V29OE) and the only >satellite traffic I ever heard was on AO-51 V/U FM (VK's of >course).

And the only P29s I've worked on the birds have been Americans who were working in PNG! :) Unfortunately, you weren't one of those I've worked. >The thing that really annoys me, though, is that I saw Drew's >posting, I wrote down the new uplink frequency, I had it in front of >me on a sticky note, and I still didn't connect the dots when I >couldn't hear myself in the downlink! I deserved to miss that grid :-) In the famous words of Homer Simpson...
