The service type for Racing Officials and Racing Frequencies when selected show up as On flages in your profile.config file in position 9 and 10 on the CustomServiceType line when looking at the Profile.config file with a text editor. You will not be able to select these service types on the HP unless they are coded that way in the database you have selected.
I do not think in the latest database there were any frequencies coded with these service types. I think someone had posted that they were coded as either transportation or business service types but the text name was racing related.
I always thought it meant racing as to teams, which they do not list and also change frequently. They are business in the RR db which is what feeds HP.
If it's a licensed business - it will be listed, that's how RR works. Whether it's correct is another thing, especially where it might have a description and not maintained, also some tracks will be listed under the business name and not so ovious.
