You do not need to (pay big $$). Microphones are so EASY ... A Cave Man Can Do It. Numerous magazines articles have been written for decades on building a $10 microphone. Sadly, this technical hobby has operators without Basic Knowledge and Skills. Find a non-working desk microphone (Often Free or Goodwill stores) and repair it. At most, it would require: 1.) Maker or Fabrication skills (basic shop), common shop tools, plus soldering skills. 2.) New microphone element. 3.) New PTT switch. 4.) New wire / connector between desk microphone and radio. August 2014 Example: Repair of Shure 450, series II (FREE, not working, BigBox retail store) Obviously required a New cord, BUT earlier repair attempt (?) damaged the PTT switch. https://forums.qrz.com/index.php?th...he-gotcha-in-this-repair.447172/#post-3240843 Former Cable appears to have been “Ripped out” braking off the brass solder lug on the Leaf Switch (Push-to-Talk). Switchcraft still makes that part for Shure, so just required ordering repair part.
