Reading pet tags

Hey all,

i have a couple of dogs that have been chipped, but I'm not entirely sure what type of pet tag they got. They came from different rescue groups, so I know they used different company products. I am assuming they are FDX-B 134KHz, but not sure. Any advice on how to find out? A generic lf read doesn't seem to find anything.

I'm running PM3 RDV4 with the Proxgrind long range reader set F=134 Q=7 and get the following on one of the dogs

[usb] pm3 --> lf fdx read
[#] LF signal properties:
[#]   high..........146
[#]   low...........114
[#]   mean..........128
[#]   amplitude.....18
[#]   is Noise......No
[#]   THRESHOLD noise amplitude......8
[#] DEBUG: (setClockGrid) clear settings
[#] DEBUG (askdemod_ext) clk 32, beststart 0, amp 0
[#] DEBUG DetectCleanAskWave: peaks (200) 1
[#] DEBUG: (askdemod_ext) Weak wave detected: startIdx 0
[#] DEBUG: no data or error found 312, clock: 32
[#] DEBUG: Error - FDX-B ASKbiphaseDemod failed

In that output my lf divisor is 95, but I've also tried 88 with similar results.

suggestions appreciated
