Never trust IT. Why, well just read (carefully) any software vendors disclaimer. Image Daimler would have you sign such a disclaimer when you are handed the keys of your new car. So when operating a remote amateur radio station (400 km away), you have to assume that something can or will fail, especially since you are radiating HF energy. In my case, due to a PC lock up, the 13,8V power supply and my IC-7300 transceiver were forced to remain switched on for 14 days (times 24 hours). Luckily the IC-7300 has a screen saver… So what’s your plan B when your PC or networkRead More →

Back in 1993 you had to compile the Linux kernel from source and modules were not invented yet. But we had this amazing kernel configure script to set things up. If somebody claims to be in the networking business for a long time, ask him which number comes to mind when you say 3Com (correct answer: 3c509, wrong answer: Is that a Telko?). Getting your 3Com adapter to work with Linux was easy. But then came this wireless stuff…closed source drivers…reverse engineering…NDIS Wrapper… Unfortunately now, many many years later, this “wireless stuff” is still a big source of problems on linux.

Note: This post applies to RS-BA1 version 1.93.

The Icom RS-BA1 software is being discussed a lot. Some claim that it is totally crap. Others happily use it. I’ve tested the software with my IC-7300 and concluded that it works fine. Actually it works so much better than I expected. Even more, I can remote control my TS-2000 with it as well. So why these diverse opinions? My guess is that there is little knowledgeRead More →

A WLAN client is normally an endpoint in a network. If you want to connect more IP’s to it, you use routing. It’s as simple as that and this will always work. Then people started to use game consoles with ethernet ports, of course located far away from the WLAN Access Point. Just wire it with UTP and you’re good to go. Well, so far the theory. In real life, having UTP across the living room might provoke some comments. So you put up a second WLAN router as client and connect the game console “behind” it with a short ethernet lead. Problem solved? Yes,Read More →
