Hello Lyle! Tnx fr replying. I can confirm that the MON function is causing more aliasing. I cannot confirm that the artifacts are not in TX audio. With settings around CMP 10 I can start hearing "double whistle" aliasing monitoring on an ext receiver. Without RF processing the signal is very nice & clean.
Also checked some "analog" counterparts of RF processing, which do not have this "mirroring" effect. I understand you have to find the best compromise between processing bandwidth and latency in K3 as a whole, but maybe the RF processor is a small bit too economic? 73' Paul PD0PSB I ran some tests here this morning regarding this. The MON function, which allows you to hear your transmitted audio, is the source of the aliasing artifact you are hearing. I deliberately removed most filtering from the demodulator to minimize delay. The downside is lack of alias suppression. I also confirmed that this aliasing product does not go over the air; it is local to the MON audio. Meanwhile, your transmitted signal is clean! 73, Lyle KK7P -- View this message in context: http://n2.nabble.com/K3-RF-speech-processor-%3E-aliasing---tp3017711p3019993.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ 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
