Robert, That statement is not a consideration for the KPA100 or without the KPA100. The additional mic gain *may* be required for *some* microphones - most notably those with Heil HC4 or HC5 elements which have about 10 dB less output than most other ham microphones. Other low output dynamic microphones may also need ampliication. Note that the additional amplification is needed for these microphones whether or not the KPA100 is installed. If the microphone is an electret type element (needing the bias resistor), then additional mic gain is not required.
Check on 10 meters using a dummy load - I suggest setting the compression (SSBC menu parameter) to 3:1. Set the K2 to display ALC - if any bars are illuminated, you have adequate mic gain. Do not overdrive the mic input unless you want to create the "CB" syndrome of "All Controls Full Right" and have your ham neighbor endure the resulting splatter. 73, Don W3FPR Robert Wood wrote: > > 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 > > 73 Robert > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
