Hi, I completed the build last night, and I am putting the rig through its paces. I previously had a K3, so I am familiar with the menu and configuration.
I configured the filters in the K3S as follows FL1 - 6 kHz FL2 - <empty> FL3 - 2.7kHz (-0.95 offset) FL4 - 700 Hz (+.04 offset) FL5 - 400 Hz I have tuned to a strong carrier (on CW) and then progressively narrowed my bandwidth. When I hit FL5, the audio is strongly attenuated. It basically disappears. I thought that something was wrong with my configuration, so I checked it again. FL5 was set for 400 Hz, which the filter in FL5 is. I performed several experiments. Choosing the filter with the XFIL button does the same thing. Audio is present with FL3 (2.7kHz) and FL4 (700Hz), but gone with FL5 (400Hz). Then, I went into the firmware and changed the bandwidth of FL5 to a narrower value (e.g. 250 Hz). I returned to listening to the audio and using XFIL produced the same results as before; however, when I tuned down from 700Hz to 400Hz, the audio was still there. When I went to 300Hz it was still there -- but it disappeared at 250 Hz (as I had set the filter's bandwidth in the firmware). Help! There's gotta be something simple but critical I'm missing...somewhere. Before you suggest it -- yes, I have tried to up the dB of the filter compensation for FL5 (400Hz). I increased it to the highest value, and the signal is still basically gone -- but maybe slightly higher. -john NE4U ______________________________________________________________ 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 Message delivered to [email protected]
