Bill, Good information on your blog. For additional information on setting the K2 filters and the dial calibration, I refer you to the K2 Dial Calibration article on my website. Yes, once set the K2 filters will stay put. There is no need for continual filter changes unless the K2 owner is simply experimenting to see what works best for him/her. See the K2 Dial Calibration article on my website www.w3fpr.com for more information on how to accomplish the optimum filter settings for your K2.
My recommended RTTY filter set settings are - FL1 = The same as the SSB FL1 settings - that gives you the full waterfall display - FL2 = 1.00, FL3 = 0.70, and FL4 = 0.40. Those narrow filters are centered at 1000 Hz (change the KDSP2 RTTY filter centers to match), and set the MMTTY mark frequency to 910 Hz. When tuning PSK31 signals in the midst of QRM, use the VFO knob to tune the desired signal to the vicinity of 1000 Hz on the waterfall, and then if you need to narrow the IF filters to alleviate QRM, it is a simple matter of tapping the XFIL button. Note that there may be a slight difference in the BFO frequency (up to 20 Hz) when switching IF filter widths. To maintain a QSO and keep the QSO on the same frequency, unlock the transmit and receive frequencies in the data mode application when using these techniques, and you will avoid chasing the QSO frequency up or down the band. 73, Don W3FPR On 3/1/2011 9:01 PM, Bill Coleman wrote: > > Ribbon cable position makes a difference, I found.
