Here is the link to the project. This link is also on the hamvoip.org web page.<br><br><a href="http://crompton.com/hamradio/818_transceiver_module/" target="_blank">http://crompton.com/hamradio/818_transceiver_module/</a><br><br>This is probably not a project for the beginner but it should not be too hard for those that have been building for awhile. Please read the cautions and comments I have made about the module. This is a cheap Chinese module intended for "Walkie Talkie" applications and at less than $15 for the module it isn't going to be a $150 or more Japanese rig. Pay particular attention to the output spectrum of the module. They do NOT meet FCC specs without an output filter. Using it without a filter on a dummy load should be OK and would work in a limited local area. With a filter, as described on the web page, it works fairly well for a local limited distance node. I have even built a local repeater using two modules which is also shown on the web page.<br><br>Chris, W0AMN has written a Python program to program the module which can be done very easily on the BBB with a USB to serial adapter. You can download the program now and it will be included in the next BBB Allstar release. Details are on the web page.<br><br>Have Fun es Happy New Year! </font><br><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br><br></font> </div></body>
