Posted on May 29, 2011May 29, 2011 by abram

In the event that anyone decides to use a junked iBook in a Linux environment, I’m hoping that this article might save someone a lot of experimentation. The Problem: Started having trouble getting packet information through Soundmodem after a system upgrade to Kernel version 2.6.36-gentoo-r8. I began to investigate the sound card using Audacity then…

Gentoo: Swappiness and CFLAGS for PPCs

Posted on May 26, 2011 by abram

Old iBooks are still around and most you can find for very cheap if not free as it was in my case. Ubuntu Linux runs quite well, but I must admit that my love of lengthy compiling and customization leave Gentoo as my primary mainstay. make.conf for iBook PowerPC 750/745/755 (G3): CHOST=”powerpc-unknown-linux-gnu” CFLAGS=”-mcpu=750 -Os -pipe”…

Experiments with the ISS

Posted on April 29, 2011May 2, 2011 by abram

I’ve attempted for months to catch a signal from the ISS as it quickly flies over head. Being in such a low-earth orbit, the longest pass you can catch is about ten minutes long. Yesterday, I was able to hear a bit of the APRS packets coming off the transmitter. Mac platforms, unfortunately, have little…

Posted on December 31, 2010 by abram

The other day I was able to send transmit and receive an SSTV transmission across the room using two Yaesu HTs and a trial copy of MultiMode from Black Cat Systems. I was rather surprised by the quality of the analog television signal sent using an narrow-band FM carrier. I was required to construct a…

about

Abram Morphew is an electrical engineer, bedroom musician, composer, naturalist, and amateur scientist. I play music in the the binary marketing show. This blog is a catalog of stuff that I make or bits of information that I think could prove useful later on when memory fails me.

 

I currently hold an Extra Class Amateur Radio Operator license and transmit on the air as K2NXF.
