-NOVA 4 was launched from Cambridge about 1:30pm - I began to track it from Felixstowe Cliff tops at about 2:20pm. NOVA was transmitting on 434.650 - alternating 50 and 300 baud RTTY messages.  I used my usual YAGI and stand into my Ham Radio rig and trueTTY software on the PC - I used the 300 baud messages throughout the flight.+NOVA 4 was launched from Cambridge about 1:30pm - I began to track it from Felixstowe cliff tops at about 2:20pm.

-I started to log data from NOVA at 14:24 (at which time it was about 10Km West of Sudbury Suffolk) the and carried on to after landing at 15:02 - the last full message was from 1424m up (14:59:47)  - I lost some messages due to re-tuning -  but I got partial messages from 390m and then one more timed at 15:01:55 - based on the 8m/sec descent rate the last message must have been from about 300m (about 1000ft)+I started to log data from NOVA at 14:24 (at which time it was about 10Km West of Sudbury Suffolk) and carried on to after landing at 15:02 - the last full message was from 1424m up (14:59:47)  - I lost some messages due to re-tuning -  but I got partial messages from 390m and then one more timed at 15:01:55 - based on the 8m/sec descent rate the last message must have been from about 300m or lower.
    
 The path distance from Felixstowe to the landing spot is about 35Km - the NOVA team used the 1424m reading and the latitude from the 390m reading to estimate the landing spot as about 51.952257, 0.848971 The path distance from Felixstowe to the landing spot is about 35Km - the NOVA team used the 1424m reading and the latitude from the 390m reading to estimate the landing spot as about 51.952257, 0.848971
  
-I drove to that location and got there about 15:55.  I got a weak signal from NOVA on the whip antenna inside the car - so I used the yagi again - the signal was plenty strong enough to copy the messages fully on trueTTY - which showed the actual landing spot was about 800m East. I programmed the landing spot into my Garmin etrex - followed it to the nearest location to the road - which was the entrance to a field - the payload and parachutes were clearly visible in the field.  The NOVA team turned up about 30mins later. +I drove to that location - arriving about 15:55.  I got a weak signal from NOVA on the whip antenna inside the car - so I used the yagi again - the signal was plenty strong enough to copy the messages fully on trueTTY - which showed the actual landing spot was about 800m South East.
