Timetable Project

Some years ago, I decided that I wasn’t completely happy with having to carry printed timetables, or having to scroll though big PDF files while chasing Trams on my visits to the Blackpool Tramway. 

I figured that it would be better to be able to access the timetables on my phone. As I was incapable of creating Apps for both the Android and iPhone platforms (seriously, have you seen what you have to do to become a developer for iOS?), I decided to do it as a mobile-friendly formatted web page. How hard could it be?

Really, how hard can it be?

What if The Arkenstone was a Silmaril?

Right, this is going to be a long, rambling text about The Lord of the Rings, The Hobbit, and The Silmarillion.
The Lord of the Rings was a actually a long text about two hobbits going rambling, but that is not the point here.
If you don’t want to read my badly thought through notions about some overly long books (and a quite short book that was made into three over long films), then look away now.

But I want to read this drivel

Linux SDR APRS IGate setup

Ok… Firstly, there are many guides to doing this already on the internet, but most of the use a Raspberry Pi. I’m not using one, for reasons that will be made clear later.

Secondly, I couldn’t find any one of the guides that did exactly what we wanted.

Before you read all this rubbish, it is important that to use it you will need an Amateur Radio License and Callsign, and and APRS-IS Passcode. If you don’t have them, then go and get them before continuing.

So, with that in mind…

On with the motley

Simple PC to Baofeng Audio Cables

This post is not about the the PC/Baofeng cable that is used for programming the radio. If you want one of those, then try Amazon.

This is about connecting the audio streams twixt the radio and a PC.

The basic mission is to take the Soundcard in/out from a PC and connect it to the Kenwood K2 connector that the Baofengs uses.

These cables are simple, and they work, but they may cause damage to either your PC or radio if used incorrectly. Much like a can of Coke.

UPDATED WITH DIAGRAMS FOR THE MENTALISTS

Only read on if you understand the risks

APRSdroid without a radio

If you are getting started with APRS, then the easiest was will be to do it on your Smartphone. This post is only about using Android phones, obviously. The clue is the “droid” part of APRSdroid.

NOTE: for this you WILL require an Amateur Radio License and Callsign. If you do not have a Callsign, then I suggest you just watch what is going on on the APRS.FI website.

So you’ve got that this isn’t about iPhones?
