Bluer White – Peter's explorations in technology
At KansasFest 2020, I shared a presentation on the intersection of the Apple II and the amateur radio hobby. The slides are here .
I acquired an old AEA PK-232MBX controller for amateur radio digital communication. I already have a more modern Raspberry Pi running Direwolf , but the prospect of creating a 1980s/1990s vintage station with an Apple II is irrationally appealing. The opportunity to combine two hobbies, amateur radio and retro computing, is interesting.
I purchased my PK-232 untested from eBay. While it appears in good physical condition, I started with the loopback test from section 2.5 of the manual . After passing that, I moved on to the alignment procedure in Chapter 6 of the service manual . Although written for a slightly older PK-232 revision, the alignment procedure remains applicable. The alignment procedure is mostly straightforward, but I found two points confusing.
