I have a Eggtimer TRS and an Eggfinder Mini flying in different rockets now, and I think I am seeing worse tracking and radio connection performance out of the Eggfinder Mini. Is this normal?
Eggtimer TRS currently has the wire whip antenna and the Finder Mini has the stock screw on antenna.
Using an Eggfinder LCD receiver with the SMA connector and the long plastic shelled antenna Cris sells.
Both units working off a 2S lipo for board power.
Example, when my Eggfinder LCD receiver is connected to the TRS it usually shows about 14 satellites in view and the Eggfiner Mini shows about 7 satellites in view. The mini also takes a few times longer to get fix and can't for example, be under the hatch of my car at the launch field.
Ground performance seems to be better with the TRS as well. LCD doesn't show the "countdown since last communication" from as far out on the TRS compared to the Mini. The last landing I had with the mini the rocket was only about 1000 feet away in gently rolling sand and brush and I was loosing connection. I have not yet done a 1 to 1 test by placing in the same locations yet.
Near as I can tell the mini was soldered well, with extra care to get solder on all the ground plane pins for the GPS module. Not sure what else I could have done that would effect performance.
Is there anything I should look for on the board, or are these performance differences normal?
