Welcome to the forums:
Go to
www.broadcastify.com. Sign in using the same credentials you use for Radioreference (you're already a premium subsciber so it should work). On the top menu click
Listen > Archives. Choose your country, state, county & agency. You'll be presented with a calendar page where you can choose day, start and end times. You can click each timeframe to listen within your browser or click the download arrow to download to your computer. Hope this helps
