Re: [Flexradio] Electret Mic

The 505 will work; however, you need an  8 volt source to power the TT mic.   It may be possible to take the required voltage from the SDR1000, but the Mic input plug would have to be rewired [TT supplies the 8 volts at pin 4 and uses the outside connector for the ground.] John
