[DARARepeater] Hacking the UV5

[Steve Reed]

Fellow Thursday nighters...

Those of you who  missed the meeting, or wish to do further study of the
chips and modules discussed tonight: I submit the following links.

For information about Repeaters and ham use of commercial radio gear...
The Repeater Builder Technical Information Page
<http://www.repeater-builder.com/rbtip/>

*The repeater-builder Yahoogroup that is associated with this web site has
over 5,200 members worldwide and is a tremendous resource of technical
knowledge on repeaters and repeater-building, be they amateur, commercial,
GMRS, public safety, CAP, or ...*

This is the email reflector which contained the messages about replacing a
crystal with a synthesized rf source.




KK6BWA <http://elazary.com/> web page with articles about "Hacking the
BAOFENG UV5R"

     On the left of his page is a TOPIC called Ham

     Then follow the links to "Baofeng Radios"

     Most of the material we looked at is under the #5 Article Titled
"Hacking the Baofeng UV5R"

      This series of web pages includes links to:
            Chirp Programing Software
            UV5R schematics
            Information about disassembling  the radio
            The EM78P568 Microcontroller
             And the RDA1846 "single chip transceiver for walkie talkie"
(which can be purchased in single quantities for about $5.50 each



Finally, the DORJI High Power Voice Transceiver Module
<http://www.dorji.com/pro/Modules/Audio_voice_transceiver.html>

     This is the module that is based on the RDA1846 chip

     Follow the links on the right of this page for info on:
     the VHF and UHF versions
     Application circuit
     and other programming and control documents


     These modules are available on Ebay for $11-14 each
     Search Ebay for either "dra808" or "dra818"  i was searching for
"DORJI" at the meeting and got poor results
     OR try viewing the Ebay Store for seller DORJIGROUP
<http://stores.ebay.com/embeddedsolution/>


      just noticed that they sell an Arduino 433MHz transceiver module with
a "DRF1278f" chip on it... could a HAM remove that chip and put the RDA1846
in its place and have an Arduino controlled UHF transceiver???



Thank you all fro your interest, hope this info has/will inspire some of
you to expirement and have some fun with radio!!
