LF broken - not rdv4 specific, all hardware.

Only happening with this firmware. original and iceman are ok. See below:

[=] measuring antenna characteristics, please wait...

[+] LF antenna: 67.13 V - 125.00 kHz [+] LF antenna: 41.50 V - 134.00 kHz [+] LF optimal: 69.11 V - 126.32 kHz [+] LF antenna is OK

[+] HF antenna: 47.02 V - 13.56 MHz [+] HF antenna is OK

[+] Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.

Dang, one of my upcoming changes got pushed to repo..

https://github.com/RfidResearchGroup/proxmark3/blob/master/armsrc/appmain.c#L1285

Three lines needs to be reverted back.

[RfidResearchGroup]

Should work now. Check and close!

[TomHarkness]

Confirmed - fixed.
