On the Hamradio Friedrichshafen I got myself a Wouxun KG-818 VHF (5W, 136-174.995 MHz). I plan to realize a small APRS transmitter for my car.
…whithout batteries. You have to remove the screws on the bottom left and right…
…as well as the nut around the antenna connector …
…to slide-wedge the whole assembly bottomwards-out. The dials will come off as well as some plastic thingy. Beware of the ribbon!
The two modules. On the left the processor/TRX-board, on the right, the LCD/speaker/kexs section with part of the case.
And once again the TRX/Chinagirl-module. Unfortunately the PCB is soldered to the RF-connector, which prevented me from further teardown, because I had no soldering iron at hand. Underneath the firmwaresticker it reads “M64X802″.
Great!” The TRX works even without its keys/speaker etc attached!
Well and that’s about it. I will mod this further so stay tuned.
It was once a gain HamRadio Friedrichshafen-time. I was there – unfortunately on sunday. So.. Here are the pics.
This was in my mail today…
It’s from Digi-Key! Let’s crack this sucker open…
Ok, I’ll see what I can do…
Look!!! I found an eZ430-Chronos!
The Chronos was on sale on tiDeals for $25 or so, so I bought one…
Little extra: The CHronos RF modem and a MSP-eZ430U Debugger (epic win!!)
As Dave would say: “Don’t turn it on, take it apart” (actually with the supplied screwdriver..), this is what you cet; the Chronos watch module (with debugging connector).
Unfortunately the Chronos is a little ugly (even more than on the website – so I think I won’t wear it.. ). Also it consistently measures the altitude 500m too high (haven’t found barometer setup yet). But it sure is a great toy and the MSP-eZ430U Debugger/Programmer is worth it’s money.
So.. Stay tuned!
I do (of course) have an antenna on my car, which was to date mounted with a pretty rusty old magmount. I don’t know; our local marten didn’t like that at all, the RG-58 which was unprotected ~20cm was completely torn to peices.
To cut it short; I didn’t document the process. I could only reuse the magnet from the original magmount, the connector was completely encased in PVC and thus irretrievable. So i turned a new connector holder out of delrin (POM) and milled the fitting for the connector with my CNC. After I de-rusted the magnet, drilled matching holes, applied a base coat and some layers of laquer I screwed on the holder with V4A INOX screws.
Tada…. (click for larger..)
The Termometer for my FrancisFrancis! X1 is done…
