I found the schematic of icom's HM-7 hand powered mic.
One of the resistors inside is 18KOhm or 1.8KOhm ???

Thanks

Hello Kosmas, I looked inside my HM7 mic. which
came with my Icom 740, the resistor is one point eight K.
(1.8k), and is in parallel with the 4.7uf. capacitor as shown
in the schematic. I checked the value of this resistor with
digital meter,and it confirmed this resistance value.
