inexpensive node transceiver using the SA818 VHF/UHF transceiver modules. 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>
