External audio with USB 1.1 and Gentoo Linux PPC…
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
Old iBooks are still around and most you can find for very cheap if not free as it was in my case.

Experiments with the ISS
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.

experiments with SSTV…
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…
