Not sure what version my P2V+ is but it is not a V3. It will intermittently only acquire 6 sats at startup on the ground and frequently drops to six sats while airborne after previously acquiring 7 or more. It will drop at least one satellite every time I start the movie camera. I dug through all the threads and started by re positioning the cable under the original shield with no help. I then installed the foil mod with no help. I then installed 4mm Taoglas module per a thread recommendation with no help but it appears I may have used the wrong module. I used Taoglas P/N CGGP.25.4.A.2 (Digikey P/N 931-1126-ND) but this is a Glasnos module running at 1575.42mhz. Another thread mentions Taoglas P/N GP 1575.25.4.A.02 (Digikey P/N 931-1015-ND) which is a slightly lower frequency of 1575 mhz. Can someone clarify which module I should be using on a P2V+? I also have another P2V+ only this is a V3 and it has no problems with satellites in the same location.My P3P will get 14 to 16 sats in the same position. Also anyone have a source for the very small low quality mounting screws for the gps board? Any and all suggestions appreciated.
