I suspect that the difference I saw in the offset for 20M was indeed due to a different filter selection. If I center the signal on the NaP3 indicator using my most-often-used 400 Hz filter, advancing through subsequent narrower filters I see just a bit of movement of the signal relative to the pointer. But, with the two wider filter positions, the movement is substantial and would require a much larger or smaller offset in NaP3 to get the signal aligned with the pointer.
With a bit of work, I can probably get the signal and pointer pretty much aligned by tweaking the BFO settings for the wider filters. I'll watch the shape and position with Spectrogram while doing that. By the way, this isn't just an academic exercise. When I'm operating split and chasing DX, I often need to be able to position the transmit VFO pointer on a signal and have the K2 exactly on that frequency and not a couple hundred Hz away. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-and-NaP3-IF-offset-values-tp7610348p7610356.html Sent from the Elecraft 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 Message delivered to [email protected]
