Ok so i just got back from a great day of flying, but had one problem with my blackstork osd ver. II. My gps data was comming in wrong. The altimeter was about 100 feet off sometimes sometimes even more. Also the thing that tells you how far away from how was off about 1/10 of a mile maybe even more. I maped my journey on google earth and thats how I know it was off. I have a 900mhz 500mw setup. The gps is in the front of the plane on the nose and the the video tx is near the rear of the plane. I have heard that 900mhz can effect the gps signal. When I start the gps i usually only get 4 sats sometimes 5. Im in a really clear with no obstacles. Should i put a low pass filter nose reduction. Would this help or is there something else causing this problem? Thanks
