My custom design modernizes your old Astatic D-104
Design supports G stand, UG8, TUG8, TUG8, TUP9

I've been experimenting with MANY headsets over the last years, I had previously used a Heil headset til now. 

This element far exceeds mic specs for optimum use with todays radio technology.   I designed this application for a direct solder in replacement that brings Hi-Fi audio and new life to my old amplified D-104.  I now have this available for the D-104 for the following stands:  G, UG8, T-UG8, T-UG9, T-UP9.  This is an electret mic replacement that will be powered by your radio's mic connector with the amp board removed (please see radio list below). 

Upgrade your old classic and get good audio reports!!!
  It's a 15 minute job to replace and it works great!!  Features great sound with full range audio, I've been getting nothing but excellent 'ON AIR' audio reports ("Sounds just like you, Bob!").   50 Hz - 16 kHz wide range FLAT Response - Natural Sound   Finally, a way to upgrade from that shrill, top end sound offered by similar crystal replacements!   This auction is only for the "W2ENY HIFI D-104 Replacement" kit with short tinned leads, resistor jumper and new black felt shown in the pic - all else in the pic is shown for illustration only.

Electret Mic element, resistor, black felt and instructions are included.
