[Elecraft] [Elecraft-KX] Help! MH3 mic PTT broken, fixable? - ELECTRET MICROPHONES

[Bill Steffey NY9H]

most ANY electret microphone element will be excellent for use with ham 
radio. The Panasonic are among the most expensive ( 8pcs New WM-61A 
Panasonic Electret Condenser Mic Capsule Mic   )   on ebay

That leaves the case cord and plug for the "mic" factory to finish. Many 
of the fake 'icom" mics I have bought on line have had the vinyl ( NOT 
RUBBER)  coil cord DISINTEGRATE into peices 3-4 years later. Never has 
issues with switches or the cases. Remember some rigs , especially ICOM 
need the higher output level found with an electret, as they are 
designed / supplied with an eletret.  Elecraft , in their wisdom, 
provides enough gain so while electrets work, there is enough gain to 
easily use a dynamic microphone. Remember when Heil sold microphones for 
icoms that were way too low on gain. So bob then sourced mics with 
electrets ( higher gain) for icom.

I spent 20+ years working under contract for ( in order) Sennheiser 
1976-81; AKG 81-86 Shure 86-91...while I am not an engineer one learns 
much along the trip.
