I have lots of outboard audio gear. Compressor, limiter, mic pre, eq's, etc. I use that primarily with my old KW AM transmitter, but have found that just using the mic preamp and a Heil PR-40 into the Flex sounds GREAT on AM or SSB. I'm not even using the built in EQ and got some very good audio reports on AM just yesterday. The key is the transmit bandwidth you use.
John (W5GI); I do think in addition to the 10 band EQ, it would be very helpful to have an audio limiter built in for AM use. Is that possible? Seems that since the code is there to measure mic level already, that a soft limiter could be coded with a user definable threshold in dB units... 73 Brian / w5ami On 1/29/07, Jeff Anderson <[EMAIL PROTECTED]> wrote: > Ed, I use a Heil Pro40 and run it directly into the SDR.
