Some of the key functions are:
- Interfaced with QRZ.COM e HAMQTH.COM for rapid search and QSO data enhancements (massive update supported).
- Innovative graphic DX Cluster management, with SPOT real time view on world map and auto tuning of the radio with CAT support.
- Super Cluster: An alternative cluster based on online data sent by users to HRDLog.net
- MySQL support for large databases and multi operator operations.
- CAT support for numerous radios, through HAMLIB and OMNIRIG
- Cluster integrated with propagation informations by HRDLog.net
- ADIF import and ADIF / Excel (csv) / PDF export of log
- Integrated with E-QSL, LOTW, ClubLog and HRDLog.net.
- Fast and simple forms for help OM’s to write old good paper QSL with ease.
- Complete log searching features, Log4Om enables the OM to update offline the QSO with updated informations.
- Optimized for “paper to electronic” log conversion, with features that drammatically speeds up the speed of inserting QSO (auto-time functions with predefined QSO separations, automatically set timings for fast pile-up management)
- Language selectable English and Italian
- Complete label print feature— — —
- Log4OM 1.11.4 (123) DUE TO SOME COMPONENT UPDATES A FULL UNINSTALL OF PREVIOUSLY INSTALLED VERSION IS REQUIRED
- Log4OM 1.11.4 Portable (USB key version) (25)
- Log4OM latest user manual (ENG) (471)
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.
