A Screen Shot of the new QF-1A Audio Filter Database.
Above is a screen shot of the QF-1A Audio Filter Database Update Form.
The form contains a number of fields where information is entered describing
the signal heard on a particular frequency. In addition, there are graphic
type fields to enter the settings used on the Audio Filter for improved
signal reception. You will notice that the settings are laid out to resemble the
twelve hour positions on a clock. This is the method used in the instructions
of the QF-1A audio filter.
The QF-1A software application is a basic database to help keep track of the
best settings setup on the audio filter.
If you would like a free copy of the database, send a short email with your
