[Elecraft] K2, how can I increase the transmitted audio ?

[Ffive VHN]

'allo,

Here is this old chestnut again. I've looked thought the archives and found lots , too much info.

In order of easiest/most efficient, what are the best mods ,

Is it?

1, change the R14 1k resistor to a 10k resistor on the KSB2 board.

2, build an audio amp from the microphone.
(can someone please point me in the right direction for an easy simple cct, tnx.)

3, re align  the filters, 


thanks
