It may be a bit too late, but I would hate so see you go.
I am a very infrequent visitor to this forum.
I expect that you did not get a reply for a long time because this topic is in the Satellite information Service forum, which, according to the description, is
An area to discuss the design and development of a system to maintain information on satellites and their characteristics
Since most people will not look in here because they are not interested in database design and discussion, this is why expect no-one replied.
Also, note that you are posting in the FUNcube satellite forum, and the main focus of this group is to receive FUNcube and all associated soft and hardware questions. Since your question is not about receiving FUNcube but the use of the FUNcube dongle, may I suggest you head over to the FUNcube dongle support group on Yahoo? You will probably find more answers there.https://uk.groups.yahoo.com/neo/groups/fcdproplus/info
Hope that helps
