The Panasonic insert is polarized so ensure that the + side is connected to the pad which is connected the the new 8.2K resistor.2pcs WM-61A Omnidirectional Back Electret Condenser Microphone Cartridge Capsule. This enabled the new insert to be fitted as a push fit with no glue or holes being drilled in the microphone body.įinally the PCB was mounted back into its original position and the 2 wires from the insert soldered back onto the microphone wire pads. The new Panasonic insert is only 10mm in diameter so I cut out a perspex disc to the same diameter as the original insert.
Panasonic wm 61a electret condenser microphone series#
To the top side of the PCB I fitted 1uf and 50nf capacitors, wired so that the switch would switch in either value in series with the microphone output. I then fitted a 10nf capacitor and an 8.2K resistor to the bottom side of the PCB. The microphone is a push fit into the front moulding of the microphone body, this needs to be unsoldered from the PCB and then the resistor, capacitor and the 2 wires to the switch need to be removed. The first thing to do after removing the cable is to remove the back of the microphone which is held on with 3 screws.Ī further 3 screws hold the PCB in place. I followed the method used by George Smart M1GEO and used a Panasonic WM-53B insert, I am very pleased with the results. There are a few published articles about converting the microphone to an electret condenser and this for me seemed a good way to go. The only thing about the FT-817 that I don’t like is the lack of talk power from the MH-31 microphone and the fact that there isn’t a speech processor.
