Active station (this computer/browser)
Set which callsign you are entering reports from. This is saved on this computer/browser and does not affect other users.
1) Import a callsign from QRZ
Imports station details + coords. This also sets the station as active on this computer/browser.
Use this if QRZ puts your home spot in the wrong place. Once saved, these coordinates stay in use until someone runs Refresh QRZ Info.
Refresh every stored callsign from QRZ and write the updated station details back to the data file.
