I would suggest using an SDR receiver and DSD+ with SDR#. The newest versions are very easy to install and the SDR dongles are cheap from eBay or Amazion.com. and are always a bit fun to tinker with on other transmissions. I got mine from eBay and it covers HF, VHF, UHF and up.
I used the local weather service transmission to find my correction for frequencies and RR for the frequencies to listen on. There is a new DSD+ add-on for SDR# that is even simpler to use.
Once you are set up there is no need to do anything else but listen and note the color codes & slots
