The KPA100 is a "Must have" addition for the K2 K0WA comment on SSB for the K2 is right on - the KPA100 will work better if the K2 is reworked by the owner on the SSB board/input

You can use a 2N2222 amplifier and run it off 9 volt battery. Works quite well for me and helps give a little more to the SSB signal. Remember, don't over drive, but the amp will help. That is my story and I am sticking with it. ------------------------------------- That was true for me using a dynamic mic with the K2 in either QRP or QRO configuration, but switching to a electret element fixed that. Once you have enough audio to make the ALC respond, you have all the audio your rig can use. More just risks distortion as Lee points out. If you're using SSB with your basic K2 now and are happy with the results, you won't need any more audio when running the KPA100. It just amplifies the RF. It has nothing to do with the audio.
