HFTA does not include propagation values for 6 meters.  If you look
at the *.PRN files you will see values for 80/40/30/20/17/12/10 but
not 160 or 6.

When using HFTA on 6 meters (or anywhere on VHF/UHF), the 10 meter
propagation values are used because HFTA uses the next lowest values
(enter 20 MHz and you will see that the 17 meter values are used).

73,
