VX-8 data cable

by trixter on Sep.16, 2009, under Yaesu VX-8r

I finally got my CT-M11 cable today, and started trying to build a data cable for it.  I discovered that cloning does indeed go over the RS-232 data pins.  This means that I will be writing a tool to load the memory the way that RT systems does it (although I will give the software away for free :)

Additionally I pulled out the multimeter and decided to try to map the 5 pins the GPS uses.  It appears that one of the 5 is never used, without pulling apart the GPS I will not be able to easily see why it is even there.  It *might* be used if you have the hand mic that takes the GPS, as I do not have one of those I cannot say for sure.

Learn morse code by telephone – FREE!

by trixter on Sep.12, 2009, under Radio, Telephony

Out of sheer boredom I created a morse code training application in FreeSWITCH.  You call 218-339-8073 and  it will ask you how fast you want the symbols sent (1-50 wpm) and how many symbols in a group.

It will then play morse symbols, selected at random, and then a human equivalent using a TTS generated voice to read the phonetic alphabet equivalent to you.  This way you can verify your decoding accuracy.

Now when you are waiting for the bus/train to take you to work, you can use some of those unlimited mobile phone minutes and learn morse code, or just brush up on it.

FreeSWITCH has a radio endpoint!!

by trixter on Sep.03, 2009, under Radio, Telephony

I finished the initial version of my  perl script that will link FreeSWITCH to a radio device.  While I am primarily doing this with amateur radio in mind, you could use this to connect a FRS, GMRS, or other similar type of radio.

Using the FT-897 PTT control circuit, you can control PTT by connecting the various connectors to virtually any radio.  Some will not be compatible, some will require hardware modification (removal of the mic/speaker and replacing them with headphone wires and connecting the PTT button to the serial port).  I will not be discussing how to do that here.  If you can’t figure that out you probably shouldn’t be doing it.

An in depth installation and configuration guide can be found on the FreeSWITCH wiki.
