Yeah, I’d love to not DF, but the TeleMini is all that’ll fit in my 24mm 
G-motor record attempt rockets. I was looking into modifying the code to accept 
an external GPS input, but I don’t have room for one of those either.

Even with a TeleMetrum on another record attempt rocket, I still had to DF to 
find it last weekend. After landing on the other side of a mountain 2.5 miles 
from the launch pad in a low lying area, I couldn’t even hear it on my HT 
outside of 700’. I had to get inside 200’ to get a telemetry update with an 
omni antenna. Gotta love muddy desert washes!

Thanks,
Bryan
