Thanks for making this available.Its price can't be beat!

I don't see any mention of user computer requirements. What operating systems will this software work with? Linux/Mac/Windows/etc?

I am so sorry, I missed this post, still better late than never!

All windows versions from XP and later

No we don't have a Linux or OS X version

• HRDLog and Clublog upload single QSO from QSL Manager, in addition to the existing auto upload to LOTW, eQSL, Clublog,, HamQTH, QRZ logbook

• Automatic Award Recognition by reading comments in cluster a spot adds the award reference(s) to the QSO “Award program” list when a spot is double clicked.

• New search for award description or code function to QSO award management in QSO entry screen.

• Added a PTT button on the toolbar

SOTA support in detail

The latest version of this free logging software Log4OM provides full SOTA support for chasers, activators and S2S

We decided to not just include the new ADIF fields for SOTA, as most other software developers do, instead we enhanced the basic ADIF fields by including many extra features:

• The full summit list of all SOTA Associations and all of the summits worldwide enables instant SOTA reference lookup whilst adding the QSO.

• The user can add updated summit lists downloaded from SOTA at any time.

• SOTA CSV export already correctly formatted for instant upload to SOTA, no external software required for conversion.

• Import of downloaded SOTA CSV’s from the SOTA site can be directly imported into the Log4om logbook and existing QSO’s updated with the SOTA data.

• By clicking a SOTA reference in Log4OM the SOTA Associations, Regions and summits can be viewed in interactive maps online in the "SOTA Mapping Project" The maps provide a wealth of information, from summit positions, activation status and panoramic views, real-time spots of SOTA activations, user-defined tracks and routes to users' favorite summits, and much more.

• Supports Chasers, Activators & S2S activities.

• Full statistic analysis by band, mode, association(s), date range and worked/confirmed status for all three SOTA activities.

• DX Cluster can be filtered for SOTA activities

• Log4OM cluster alerts can be configured to alert of a SOTA activity by email, push alert to mobile phone of tablet, audio and on screen warnings
