W6DS operates a network monitor which simultaneously displays activity on a number of YSF reflectors including MNWis, SoCalHam (K9EQ), US-MVARC (Idaho), US-KENTUCKY, US-SADRC, plus others. In addition, you can listen to the conversations or go back in the transmission history to hear past conversations by clicking on the reflector. It also shows technical data so you can see how well you are getting in. What you want is the minimum number of sequence errors. Check out the Network Digital Radio Monitor.
