In half duplex you have to wait for a clear channel. The real feature of full duplex (being able to talk like you are on the phone) would only be achieved if you had completely full duplex systems at both ends including the user transceiver. This could be achieved without radios using iaxrpt at both ends.<br><br>You could use two cheap radios, one RX and the other TX for full duplex. You would either need enough antenna separation or use a small duplexor with one antenna. <br><br>To see my simple repeater using the SA818 modules see -<br><br><a href="http://crompton.com/hamradio/818_transceiver_module/" target="_blank">http://crompton.com/hamradio/818_transceiver_module/</a><br><br>Or the link on hamvoip.org<br><br>You could use any two radios, mix or match, to achieve the same result.<br><br>Remember to set duplex=2 in rpt.conf if you are using it as a repeater full duplex.<br id="FontBreak"></font><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></font><br><br><div><hr id="stopSpelling">From: w7ldn@w7ldn.com<br>Date: Sat, 17 Jan 2015 19:19:03 +0000<br>To: App_rpt-users@ohnosec.org<br>Subject: [App_rpt-users] simplex vs duplex for a home node<br><br>Please excuse my ignorance on this. But one of the advantages of Allstar over say IRLP is the ability to operate full-duplex. My understanding on this is limited. But apparently full-duplex is not possible without setting up a repeater. <div><br></div><div>Since many folks seem to setup nodes in their residences... is it common for them to have repeater setups that allow them full-duplex operation at home? Is there a relatively cheap/easy way to do this?</div><div><br></div><div>Any tips are very appreciated. :)</div>
