Question for Lyle or whoever might know...does the K3 DSP allow for easy adjustment of the tap setting? There are several ways to get this effect. Altering the tap settings may be one way. The K3 initial firmware provides two features that may be used to achieve a similar effect. The fi

My experience with low band dx'ing on the Orion concurs with W4ZV's - particularly in noisy conditions. Instead of using a steep skirted 400hz filter, I found that using a broad skirted but nominally narrower (100-150hz) filter in DSP consistently did a better job pulling the weak sigs out of high

2007-09-30 Thread Bill Tippett
This is a little related to the previous CW Pitch discussion. I sometimes also like a wide bandwidth and/or wide shape factor when listening to weak signals. Orion's DSP had the ability to change the DSP filter tap settings which had the effect of widening the shape factor. I notice th
