 ====== NOVA 4 Recovery (by RocketBoy) ======
-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.

-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)

 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.
