Positive "sig" values

Analysis and Data
1

Hi Motus Users;

I’m manually checking my detections to determine what seems valid (after filtering out runlen<2) and I’ve come across some positive RSSI “sig” values. What’s puzzling is that, although they’re positive, they exhibit the shape, timing, and location that could make sense for an American Woodcock I’m referring to North Tawas, Clear Lake, No Pablo, Cedar Point, OttawaWeir, and Erie Marsh 2016. Here’s a link to the graphs (can’t seem to send as attachment): https://drive.google.com/file/d/19Zd7Nn-CD5zNYVn1vT7GuILTpIodITJR/view?usp=sharing

What would cause these positive values? Could they be valid just on the wrong scale?

I’m confident that Altona and Clifton are noise (they pop up on a lot of my tags) and the MPG-MT sites.

Luke,

I think this is just the difference between Lotek and non-Lotek Receivers.

These are mostly my towers and then Chris Tonra’s Towers which are all Lotek based receivers. For us low “sig” is weak, high = “strong”

I have access to raw data if that’s helpful, just get in touch off line.
