&lt;h1 class=&quot;sectionedit1&quot; id=&quot;repeater_output_as_simplex_frequency&quot;&gt;Repeater Output As Simplex Frequency&lt;/h1&gt;
&lt;div class=&quot;level1&quot;&gt;

&lt;p&gt;
A while ago we had discussed using our repeater&amp;#039;s output frequency (147.220 &lt;abbr title=&quot;Megahertz&quot;&gt;MHz&lt;/abbr&gt;) as a simplex frequency in case of emergency.  Here are the advantages of using one of the &lt;a href=&quot;https://scarcs.ca/links/simplex&quot; class=&quot;wikilink1&quot; title=&quot;links:simplex&quot; data-wiki-id=&quot;links:simplex&quot;&gt;standard simplex frequencies&lt;/a&gt; VS using our repeater&amp;#039;s output frequency:
&lt;/p&gt;

&lt;/div&gt;
&lt;!-- EDIT{&amp;quot;target&amp;quot;:&amp;quot;section&amp;quot;,&amp;quot;name&amp;quot;:&amp;quot;Repeater Output As Simplex Frequency&amp;quot;,&amp;quot;hid&amp;quot;:&amp;quot;repeater_output_as_simplex_frequency&amp;quot;,&amp;quot;codeblockOffset&amp;quot;:0,&amp;quot;secid&amp;quot;:1,&amp;quot;range&amp;quot;:&amp;quot;26-340&amp;quot;} --&gt;
&lt;h2 class=&quot;sectionedit2&quot; id=&quot;standard_simplex_frequencies&quot;&gt;Standard Simplex Frequencies&lt;/h2&gt;
&lt;div class=&quot;level2&quot;&gt;
&lt;ul&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 Are easier to setup in the radio&amp;#039;s VFO since there&amp;#039;s no default offset.
&lt;/div&gt;&lt;/li&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 Don&amp;#039;t potentially interfere with regular repeater operations.
&lt;/div&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;/div&gt;
&lt;!-- EDIT{&amp;quot;target&amp;quot;:&amp;quot;section&amp;quot;,&amp;quot;name&amp;quot;:&amp;quot;Standard Simplex Frequencies&amp;quot;,&amp;quot;hid&amp;quot;:&amp;quot;standard_simplex_frequencies&amp;quot;,&amp;quot;codeblockOffset&amp;quot;:0,&amp;quot;secid&amp;quot;:2,&amp;quot;range&amp;quot;:&amp;quot;341-524&amp;quot;} --&gt;
&lt;h2 class=&quot;sectionedit3&quot; id=&quot;our_repeater_s_output_frequency_in_simplex&quot;&gt;Our Repeater&amp;#039;s Output Frequency in Simplex&lt;/h2&gt;
&lt;div class=&quot;level2&quot;&gt;
&lt;ul&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 There&amp;#039;s only one frequency for everyone to monitor (regardless of whether our repeater is operational or not).
&lt;/div&gt;&lt;/li&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 There&amp;#039;s no danger of the frequency being in use by another club since it&amp;#039;s already coordinated to us.
&lt;/div&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;/div&gt;
&lt;!-- EDIT{&amp;quot;target&amp;quot;:&amp;quot;section&amp;quot;,&amp;quot;name&amp;quot;:&amp;quot;Our Repeater&amp;#039;s Output Frequency in Simplex&amp;quot;,&amp;quot;hid&amp;quot;:&amp;quot;our_repeater_s_output_frequency_in_simplex&amp;quot;,&amp;quot;codeblockOffset&amp;quot;:0,&amp;quot;secid&amp;quot;:3,&amp;quot;range&amp;quot;:&amp;quot;525-798&amp;quot;} --&gt;
&lt;h2 class=&quot;sectionedit4&quot; id=&quot;examples&quot;&gt;Examples&lt;/h2&gt;
&lt;div class=&quot;level2&quot;&gt;

&lt;p&gt;
Here are a few examples of when this could be useful.
&lt;/p&gt;
&lt;ul&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 If our club repeater stops working, the “meeting place” is still the same: 147.220 &lt;abbr title=&quot;Megahertz&quot;&gt;MHz&lt;/abbr&gt;.  Those who know the repeater if offline can transmit in simplex and let others know to do the same.  Late comers will still here everyone and get the information.  If QSY to a different simplex frequency, late comers might show up on the repeater and not know where everyone is.
&lt;/div&gt;&lt;/li&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 If someone comes on the repeater and you can hear them better on the input, it&amp;#039;s really quick to switch to simplex on the same frequency without having to find a free frequency.  Longer QSO should QSY to a different frequency, however, because this will unnecessarily tie up the repeater.
&lt;/div&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;/div&gt;
&lt;!-- EDIT{&amp;quot;target&amp;quot;:&amp;quot;section&amp;quot;,&amp;quot;name&amp;quot;:&amp;quot;Examples&amp;quot;,&amp;quot;hid&amp;quot;:&amp;quot;examples&amp;quot;,&amp;quot;codeblockOffset&amp;quot;:0,&amp;quot;secid&amp;quot;:4,&amp;quot;range&amp;quot;:&amp;quot;799-1539&amp;quot;} --&gt;
&lt;h2 class=&quot;sectionedit5&quot; id=&quot;list_and_chirp_file&quot;&gt;List and CHIRP File&lt;/h2&gt;
&lt;div class=&quot;level2&quot;&gt;

&lt;p&gt;
I&amp;#039;ve updated the &lt;a href=&quot;https://scarcs.ca/links/radioprogramming#frequencies&quot; class=&quot;wikilink1&quot; title=&quot;links:radioprogramming&quot; data-wiki-id=&quot;links:radioprogramming&quot;&gt;frequency list&lt;/a&gt; and CHIRP files to add 147.220 &lt;abbr title=&quot;Megahertz&quot;&gt;MHz&lt;/abbr&gt;, T100 &lt;abbr title=&quot;Hertz&quot;&gt;Hz&lt;/abbr&gt; (no offset and no tone squelch).  The reason I setup a tone of 100 &lt;abbr title=&quot;Hertz&quot;&gt;Hz&lt;/abbr&gt; (but no tone squelch) is so that while in simplex:
&lt;/p&gt;
&lt;ol&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 you&amp;#039;ll be able to get through to others who have their tone squelch set,
&lt;/div&gt;&lt;/li&gt;
&lt;li class=&quot;level1&quot;&gt;&lt;div class=&quot;li&quot;&gt;
 but you&amp;#039;ll also be able to hear others who don&amp;#039;t have a tone at all.
&lt;/div&gt;&lt;/li&gt;
&lt;/ol&gt;


&lt;/div&gt;
