Ham Radio Deluxe 5.1
"This is our first release since obtaining the source code about 90 days ago," said Mike Carper, WA9PIE. "My partner, Rick, W4PC has done an outstanding job at becoming familiar with the code and developing the applications. We were fortunate to have a few key resources like Chuck, K7PT and Terry, G4POP to help us QA the builds as they're developed."
The 5.1 release is being made available at no charge to users registered on the HRD website. The focus for this release was a few items from the ToDo list – bug fixes, added rig support, and a few enhancements.
Mike said, "I think we've taken a balanced approach to getting something out quickly that satisfies a broad range of needs. I hope hams will enjoy the improvements. Obviously, this is only the beginning. We've got big plans and high-expectations for HRD in the future."
Following the 5.1 release, HRD Software intends to focus on more fixes and significant feature enhancements for v6.x with a target release at the Dayton Hamvention 2012.
As promised, version 5.1 is FREE!

HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
