Credit Card Number

I don't know if this is good or bad, and if either, in what way. But I have finally memorized my credit card number. I memorized the one I had before it, but it changed when it was lost, which was a good three years ago. Now, I can shop online without having to find my wallet, oh, and log on to the web site and pay the bill too.

GO-32 Satellite - APRS Operation

On my second attempt, I was able to transmit an APRS position report packet via the GO-32 satellite and receive the digipeated packet for confirmation.

How did I do it? Well, I followed Bob's directions on and used my new Kenwood TM-D710 with the dual band mobile antenna on top of Amy's van.

I'll try to explain the image below. It is a picture of the display on the Kenwood TM-D710. The top line basically says I'm in APRS 9600 bps mode and the time. The next few lines represent unsuccessful packets. The lines that matter are near the end.

NE3R-9>3Y2R2Q,4XTECH*:'i6(l ←v/]50W Mobile with 19" dual band whip=

That is my position report as I received it on the satellite's downlink frequency. The 4XTECH* represents the station that digipeated my packet.

Here is a pic of some random other packets I received during the pass.

Amy’s Van / Satellite Ground Station

I was home a little early from work today and had some time. So I checked the satellite schedule, and there was a good pass of AO-27 just after 4pm today. So I figured I would see how well the radio in Amy’s van worked for that. This is one case where the antenna not being straight up and down probably helped as it was sort of aimed right at the satellite.

I heard a few stations on, and then a break so I made a call. N5AFV from Huston Texas responded, then WA5KBH from Lake Charles Louisiana right after, and finally Leo, W7JPI from Sonoita, Arizona. All of this happened within about a minute. Since FM satellites only have one frequency for uplink that is shared among everyone, so you keep it brief, just exchange call sign and grid square.

I really need a recording device as I have a hard time operating the radio and writing at the same time. I think I have all the call signs right! The radio I was using was the Kenwood TM-D710 with a short dual band antenna on a lip mount.

WinDbg Output for my memory.dmp file

* *
* Bugcheck Analysis *
* *

This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
Arg1: c0000005, The exception code that was not handled
Arg2: 81c51e94, The address that the exception occurred at
Arg3: c23cc914, Trap Frame
Arg4: 00000000

Vista Crashed

For the first time since I started using Windows Vista it has crashed. Nothing serious that I can tell, just a blue screen of death and a reboot and all seems to be working.

Log Name: System
Source: Microsoft-Windows-WER-SystemErrorReporting

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000008e (0xc0000005, 0x81c51e94, 0xc23cc914, 0x00000000). A dump was saved in: C:\Windows\MEMORY.DMP.

I really don't have time right now to diagnose the problem. On Monday I upgraded the computer from two to four gigs of memory. It worked fine right after, but other than that, I haven't changed anything on the system. We'll see.

I just obtained my first copy of Windows Vista to install on my home computer. I hope that goes well!
