+===== UHF Ham Mod =====
+Those pagers can sometimes be found on UHF, but adjusted for 459MHz. Setting the Rx frequency back to 439.98750MHz works, but the antenna is highly desensitized and the PLL might not lock everytime. Here is a small guide for tuning one back on our bands.
+Tools needed:
+  * Spectrum Analyser
+  * Tweezers
+  * Soldering iron
+  * RF tuning screwdriver (or anything not metal to turn the trimmers)
