The controls seem so inter-reactory, by their adjustment to my eye identical echo images are displayed. Even with tune I cannot really determine any great changes. There must be some logical progression to make these adjustments rather than my constant tweaking, all guidance greatly received. Beryl. My JRC 1500 radar has an "auto-tune" setting - I leave that on, so I don't have to worry about tuning. I think the Sea and Rain settings are at zero, or very low - you don't need to turn up the rain control, unless you are in heavy rain that is masking targets. Turn the Sea control up just enough that sea returns aren't masking real targets. I set the gain just below the point where noise specks appear on the display - the gain may have to be adjusted a bit as you change ranges. -- Peter Bennett, VE7CEI peterbb4 (at) interchange.ubc.ca new newsgroup users info : http://vancouver-webpages.com/nnq GPS and NMEA info: http://vancouver-webpages.com/peter Vancouver Power Squadron: http://vancouver.powersquadron.ca |
