Hello. Proxymark3 easy isn't so

Hello all.

I recently picked up a proxmark3 v3 easy.  Flashing with windows 10 was a bit of a mess but my fedora system handled it well enough once I got all the needed packages to build.  After flashing bootrom.elf and fullimage.elf  all looks well

But when I attempt 'hw tune' I get the following.

Measuring antenna characteristics, please wait.........
# LF antenna: 36.85 V @   125.00 kHz
# LF antenna: 36.30 V @   134.00 kHz
# LF optimal: 39.88 V @   129.03 kHz
# HF antenna:  0.00 V @    13.56 MHz
# Your HF antenna is unusable.
Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.



No GUI in this build!

This unit has the integrated HF antenna on the board, and LF antenna attached to the front.
The lf seems to work well. I was able to read, clone and read again some hid cards.  But the HF seems to be busted.

Is there any way to self test or verify the hardware with respect to hf ?
