Just by way of explanation, I think what Ken really means is not a database for HRD per se, but for one of its programs known as Rig Control
Ken you're going to have to be a lot more specific, since I am willing to bet that it uses a different layout for its data for each radio it supports. And there is a ton of them, listed here...
Supported Radios Ham Radio Deluxe
I have a feeling that you will need to do this on your own (it's kinda a stretch to use a ham program for a non-ham purpose in this way - possible, but it's a stretch)
Just to get the ball rolling, this list of HF Aero freqs was updated just this past June, so it's pretty up to date...
The Btown Monitoring Post: Intl Aero HF Routed/Off Route Frequency List - Update 22 June 2016
GL with this..Mike
The Btown list can be easily converted to an Excel spreadsheet which can be stored and read by many control programs. The main problem with scanning HF frequencies is that the 'scan stop' method doesn't work very well with SSB signals as there is no carrier to raise the AGC voltage and that the communications are usually quite brief unless you get onto a particularly busy sector.. At best you should be able quickly to find the active primary and secondary frequencies of a particular MWARA area and just listen to those - the easy way is to have four of five HF receivers!
Give me the format that HRD uses for its data files and I'll try to make a file to suit. I'll need to know the headings and file type and probably I won't be able to test it as I don't use HRD so it could be buggy for the first try! Attached is a tab delimited text file of the MWARA frequencies from last year - just see if that works.
