&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Main|Unidentified Signal Source}}&lt;br /&gt;

&amp;#039;&amp;#039;&amp;#039;{{PAGENAME}}&amp;#039;&amp;#039;&amp;#039; are a type of [[Unidentified Signal Source|signal source]] where certain [[:Category:Rare materials|Rare]] and [[:Category:Very rare materials|Very Rare]] [[:Category:Manufactured materials|Manufactured Materials]] can be obtained. They are empty aside from the free-floating materials and occasionally a single, non-hostile [[Ships|ship]] that will eventually depart.&lt;br /&gt;
&lt;br /&gt;
== Signal Contents ==&lt;br /&gt;
High Grade Emissions will generate certain [[:Category:Very rare materials|very rare]] [[Manufactured Materials|manufactured materials]], depending on individual Faction States and the allegiance of the controlling faction:&lt;br /&gt;
&lt;br /&gt;
* [[Federation|Federal]] systems:&lt;br /&gt;
** [[Core Dynamics Composites]]&lt;br /&gt;
** [[Proprietary Composites]]&lt;br /&gt;
* [[Empire|Imperial]] systems:&lt;br /&gt;
** [[Imperial Shielding]]&lt;br /&gt;
* [[Faction State|Civil Unrest]] faction states:&lt;br /&gt;
** [[Improvised Components]]&lt;br /&gt;
* [[Faction State|War]] or [[Faction State|Civil War]] faction states:&lt;br /&gt;
** [[Military Grade Alloys]]&lt;br /&gt;
** [[Military Supercapacitors]]&lt;br /&gt;
* [[Faction State|Boom]] or [[Influence#States|Expansion]] faction states:&lt;br /&gt;
** [[Proto Heat Radiators]]&lt;br /&gt;
** [[Proto Light Alloys]]&lt;br /&gt;
** [[Proto Radiolic Alloys]]&lt;br /&gt;
* [[Faction State|Outbreak]] faction states and population &amp;gt; 1,000,000:&lt;br /&gt;
** [[Pharmaceutical Isolators]]&lt;br /&gt;
&lt;br /&gt;
Signals are assigned to a faction. Signals contents will be based on the assigned faction. When a faction has more than one condition, materials spawned will be chosen by a hidden rank order. The above list attempts to order them in rank priority. (e.g. a Federation or Imperial faction will never have anything other than composites or shielding, respectively.)&lt;br /&gt;
&lt;br /&gt;
== Spawn Locations ==&lt;br /&gt;
High Grade Emissions usually appear in [[Unidentified Signal Source#Deep Space|deep space]] or occasionally in [[Unidentified Signal Source#Sphere of Influence (SOI)|spheres of influence]].  Scanning a system&amp;#039;s [[Nav Beacon]] can cause High Grade Emissions to appear if none are already present.&lt;br /&gt;
&lt;br /&gt;
They are most common in high population systems (1 million or more). You can use https://inara.cz/elite/nearest/ along with the following chart to find High Grade Emissions sites.&lt;br /&gt;

&lt;br /&gt;
== Notes ==&lt;br /&gt;
In Federal and Imperial systems, any High Grade Emissions present will have their status as &amp;quot;N/A&amp;quot; or &amp;quot;Civil Liberty&amp;quot;.&lt;br /&gt;
