|

I have a very small station here that consists of a PC, KPC3+, 5 watt HT and a 5 foot telescoping antenna in a bedroom on the second floor of my house. Usually, I get only about 3-10 stations in my heard list. 10 if I'm lucky and there is alot of activity in my area.
Last night however, just after midnight, I must've had about 200 stations in my heard list. Some were from upper Michigan, Wisconsin, Indiana, lower Michigan, Ohio, down state Illinois, and even one from Canada. They just kept coming and coming, non stop. I have the radio set up so I can actually hear the audio and there was not a second in which there was nothing being transmitted by someone. Sounded like a digital mess
Unfortunately, 1 AM was too late for me to be up since I had to get up at 5:30 to go to work, so I went to bed. When I got up this morning and checked my PC, all but a small handful of stations had dissapeared, mostly very local (KG4JAM, ect)
Was this a band opening? I have never seen one happen, but from what they are usually described as, it seemed like the case. I was able to send a message to a few stations and got ack's back mostly on the first try. I know the meteor shower is going on, so maybe that has something to do with it..

It could be band opening or IGate opening. If some station is set to send from Inet to RF beacons and maybe more frames it could be such effect. And then freq. could be jammed. Check the path of frames; are there only digis or also TCPIP as the source? |

Luckily, I started recording a log when I noticed the abundance of stations. I played back the log and checked the path of some of the stations (too many to check them all). Not one of them had anything about TCPIP in it. Also, the audio that was going on at the time was not all equally clear, like I would expect if an IGATE was just pumping out everything it heard. I wasn't able to decode all of the packets I could hear, as some were a bit in the static.
Here are some of the packets:
