A suggestion would be to contact Tim through his website, politely explain that BY70-1 is of interest
to amateurs, and request that he include it in the amateur.txt list because you need frequent updates.
In the past he has been very responsive.

<Thanks for this!
<The AMSAT ftp site isn't updated frequently enough for the deteriorating orbit and a single precision
<PLAN13 implementation on the ATmega1280.
<As an example here's the CELESTRAK output:
<1 41909U 16083C 17029.24424671 .00506735 24288-5 70240-3 0 9991

<Here's the AMSAT record sampled from the same time.
<1 41909U 16083C 17026.84471594 .00329730 24344-5 49404-3 0 9999

<As expected, atmospheric drag has the largest effect on the semi-major axis, eccentricity, and
<of perigee. Alas it won't be long now. Still haven't gotten a confirmed QSO!
