<h1 class="sectionedit1" id="ic-7300_low_receive_signal_strength">IC-7300 Low Receive Signal Strength</h1> <div class="level1"> <p> When I use JS8Call with my IC-7300, I sometimes lower the RF gain so that the program receives the right signal levels. But when I switch back to analog, I sometimes forget to move it back up. Today during the net, I found some of the signal reports were pretty asymmetrical and I wondered if something similar might be happening to other people. </p> <p> So here are two ways to lower the receive signal strength on the IC-7300: </p> </div> <!-- EDIT{&quot;target&quot;:&quot;section&quot;,&quot;name&quot;:&quot;IC-7300 Low Receive Signal Strength&quot;,&quot;hid&quot;:&quot;ic-7300_low_receive_signal_strength&quot;,&quot;codeblockOffset&quot;:0,&quot;secid&quot;:1,&quot;range&quot;:&quot;11-485&quot;} --> <h2 class="sectionedit2" id="baseline">Baseline</h2> <div class="level2"> <p> With everything adjusted properly, my noise floor was S2: <a href="https://scarcs.ca/_detail/blog/2025-01-01/01.jpg?id=blog%3A2025-01-01%3Aic-7300_low_receive_signal_strength" class="media" title="blog:2025-01-01:01.jpg"><img src="https://scarcs.ca/_media/blog/2025-01-01/01.jpg?w=400&amp;tok=0724fa" class="mediacenter" loading="lazy" title="01.jpg" alt="01.jpg" width="400" /></a> </p> </div> <!-- EDIT{&quot;target&quot;:&quot;section&quot;,&quot;name&quot;:&quot;Baseline&quot;,&quot;hid&quot;:&quot;baseline&quot;,&quot;codeblockOffset&quot;:0,&quot;secid&quot;:2,&quot;range&quot;:&quot;486-599&quot;} --> <h2 class="sectionedit3" id="rfsql">RF/SQL</h2> <div class="level2"> <p> When <code>RFG</code> is displayed on the screen, it means the <code>RF/SQL</code> nob is too far to the left.
