Actually, the web site is likely from one of your old packets on the CD.? If you do an e/BG0GE-6 filter, you'll see that it's not just you, but LOTS of southern California stations.? And BG0GE-6's comment says "9600&1200 Baud Nucleo-TNC TEST", so I suspect s/he is just unaware of the fact that the test is actually being gated to the APRS-IS.

That's the "rush hour" track on the CD.? It was recorded off-the-air on 144.39 from my QTH (at the time) in Pasadena. It was a capture during the Southern Cal rush hour (which extends from about 3:00 PM until 8:00 PM!? This capture was about 4:30--5:30) reflecting the worst imaginable APRS traffic in existence, with almost constant multiple transmissions on top of each other, wildly over- and under- deviated stations, idiots with CW IDs in the middle of the chaos, etc.

You hear traffic being digipeated by 4 mountain-top digis at 4,000 feet+ elevation ringing the greater LA basin simultaneously. Frequently, two or three of the digis would each digipeat DIFFERENT stations at the same time, depending on which mobiles on the ground were nearest which digis. Note that in southern Cal, most of the time, mobiles have a true? low-loss? line-of-sight path to one or more digis, even when they were 40-50 miles away! [Most of the population of 18 million+? of greater LA is below 500-800 feet elevation, while the digis are up 4000 feet or more in the mountains ringing the greater LA area.]

[People in the flat-lands east of the Mississippi just can't imagine the APRS anarchy that extends for over 150 miles up and down the SoCal coast due to digis at multiple THOUSANDS of feet elevation.? Conversely, I have always laughed when newly-minted hams in SoCal get accustomed to hand-helds routinely working voice repeaters from 50 miles away. Then they go on trips to the Midwest or Florida,? and can't understand why they can't reach the edge of town with their $1.98 handhelds! ]

Then to make the rush-hour even worse, I edited out any dead air of more than 5 seconds (rare in that mess) with an audio editor. The idea was to provide the worst-case challenge to TNCs with under-sized buffers such as the Kenwood D700 mobile and TH-D7 handheld.


Before, this guy had only been playing the track of my solo drive test on a quiet (non-144.39) channel. The intent of this track was to challenge TNCs with a signal fluctuating between strong-signal full-quieting? and periodic loss of quieting/mobile flutter as I drove into and out of strong signal areas.? The receive/record location was at my house in Pasadena, as I drove a 25-mile loop around the San Gabriel Valley, beaconing with a D700.? The receive audio was taken off the 6-pin mini-DIN port of a Yaesu FT-1500.
