It has nice features like being able to put your own maps into it, even azimuthal maps. Beam widths of antennas can be superimposed on the compass display. So many features to explore. If you are short of screen space there are cut down versions that can show just the essentials.<br /><br />The IC-7300 spectral scope display can really show graphically how the bands are occupied. For example in a 50 MHz contest it easily shows how we have a huge part of the band totally unused, with everyone crammed below 50.300, beacons above 50.400. This just seems so strange. Why do we continue to try and cram in SSB and JT65 and MSK144 all below 50.300? It would make a lot more sense to use 50.300 to 400 for digital modes, especially in a UKAC and have SSB below that. As it stands we have a 100 kHz chunk of the band nearly empty. <br /><br />I normally have the scope display set to use fixed rather than centre, and prefer to have the whole band shown, like 50.0 to 50.5 or 70.0 to 70.5 so that I can see beacons popping up at either end on 6m or FM stations on 4m. <br /><br />Comments noted on OIRT QRM, have struggled here too, though CW does work quite well in the gaps, and I find that the noise blanker (not noise reduction) helps a tiny bit with the FM splatter at times. Again having a spectral display makes it a lot easier to find amateur signals in amongst the OIRT and helps quickly find a suitable gap to try and call or QSY to.<br /><br />73<br /><br />David GM4JJJDavid Anderson GM4JJJhttps://www.blogger.com/profile/01308957902320184832noreply@blogger.com
