I've just tried transmitting SSB using the internal mic to a dummy load, with my K2 next to it to receive the SSB signal and record the audio.
Although the background noise was loud whenever I pushed the PTT button, my recorded voice was also loud and clear. I set the mic gain to 60 and compression to 10.
So the internal mic is already useable I guess? Anyone tried the internal mic to make a real contact?
?
