Hi Folks, I just helped Vlad R7LV fix his CW cutoff frequencies. He was still seeing colored (needed) DX spots for stations he had already worked. If the CW cutoff frequencies are not set correctly, DX4WIN will not be able to distinguish CW spots from non-CW spots (unless the spot MODE is included in the comment field of the DX spot).
If you have upgraded from one DX4WIN version to another, merging your .INI file (preferences) each time, it's possible that your CW cutoff frequencies may not be correct. The CW cutoff frequency is the frequency at which DX4WIN NO LONGER considers them to be in the CW band. For example, on 10 meters (28 MHz), the default CW cutoff frequency is 28,300 KHz; DX4WIN will think that spots LOWER than that frequency are CW, and spots on that frequency or HIGHER are NOT CW. Remember, there have been some changes in the last several years regarding 80 and 40 meter SSB operation, and if you have been migrating your DX4WIN preferences from version to version, you might have the old cutoff frequencies. To check your CW Cutoff frequencies, go to Preferences and click on the QSO tab. In the bottom-right hand corner of the preferences, there will be a box that says, "CW frequency cutoff" Check each band by clicking inside the Band field and using the drop-down menu. Once the cursor is inside the Band field, you can just use the up/down arrow keys to change bands. To correct a band's cutoff frequency, type the frequency, in kHz, into the "Frequency (kHz)" field. Here are the default CW cutoff frequencies for a new installation of DX4WIN 8.05 (nothing merged into preferences): 160m: 1,840 kHz 80m: 3,600 kHz 60m: 5,330 kHz 40m: 7,125 kHz 30m: 10,100 kHz **** 20m: 14,150 kHz 17m: 18,110 kHz 15m: 21,200 kHz 12m: 24,930 kHz 10m: 28,300 kHz *** I think this is wrong. This should cause DX4WIN to treat all 30 meter spots as *NOT* CW. I think it should be set to 10,130 kHz or higher, which appears to be the start of the digital band (see: http://www.bandplans.com/index.php?band=30 ) When you are done making changes, make sure to use File | Save Changes and Exit. Before doing that, however, it might be a good time to also do File | Write INI file to save your preferences, in case something happens to your DX4WIN.CFG file, or you want want to upgrade and keep your preferences. 73 - Jim AD1C -- Jim Reisert AD1C, <jjreis...@alum.mit.edu>, http://www.ad1c.us ______________________________________________________________ Dx4win mailing list Home: http://mailman.qth.net/mailman/listinfo/dx4win Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Dx4win@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
