HF Propagation Numbers – Rules of Thumb
January 14th, 2008 by Giovanni
The following was sent by Bonnie VR2/KQ6XA to the HFPack Yahoo email list in reply to
a question about easily decoding HF Propagation Numbers: (quoted with approval and thanks):
| A low “A index” is most important! For Low Power Portable DX openings at 10MHz to 30MHz, look for an A index LESS THAN 6.
Here is my RULE OF THUMB for How To Read Propagation Numbers: The A index = LOW is GOOD.
SFI index: HIGH is GOOD.
K index: LOW is GOOD.
