No, the DSP is used for demodulation (15 KHz final IF to audio). The 6 KHz bandwidth is generally used for AM where 6 KHz at RF represents 3 KHz at audio (AM RF bandwidth = 2 x AF bandwidth). The 4.2 KHz maximum "HI" frequency is based on the design of the digital to analog converter and a decision that 4000 to 4500 Hz is the highest frequency required for communications quality audio. The K3 is not and was never deigned to be a high fidelity receiver. 73, ... Joe, W4TV On 2015-05-05 11:30 PM, KV6O wrote:
Huh. Is there anyway around this? I use data modes way more than AM, sure would be nice to be able to get the 6k filter to work! Don't need DSP for these modes....
