I was very surprised to find out that my small EME station (two 7-element VHF yagis and a preamp at the mast) was more than capable of reliably decoding the telemetry from this spacecraft! Capturing a QRP (one watt) signal from over 300,000 km away is pretty remarkable. I use exactly the same setup as I do for EME, and also run the 4M Data Delivery Client to automatically send the received packets from the 4M back to their central data warehouse. Seems at this point in time there are around 30 stations providing the warehouse with live feeds of packets coming down from 4M as it heads towards the moon!
The keplerian elements for tracking 4M seem are near the bottom of this post: http://moon.luxspace.lu/receiving-4m/ and the current position of the spacecraft is shown on their webpage at http://moon.luxspace.lu/tracking/ (for doublechecking your own tracking software).
