[AMSAT-BB] Attempt to decode NO-84

Hi, I've received two burst during last pass of NO-84 over EU, signal quite good with a bit of qsb on 435.350MHz. I've recorded the audio and than processed with fldig using BPSK-31: phase scope looks good and what I've decoded is just:

252 00 23 804 242 +20 2n B 252 00 23 804 242 +20 gy

that seems resonable data (beacon B, partial first packet) and is similar on what I've read here:

and here:

But how can I decode it? I haven't an HF TX so I cannot test uplink so I would try to get telemetry better. One more question: is normal just two burst during a 10min pass?

Many thanks!
