[amsat-bb] DSLWP Successful Configurations and Subsequent UHF Test Plan

[韦明川]

Hi Jean,

Which recording and flowchart did you use?

for 2MHz recording, you should use frontend_dslwp_replay.grc in gr_dslwp/examples.

replay_dslwp_gmsk_250bps_0.5_coherent.grc in dslwp_dev is used for 40kHz recording.

Best Regards,


Wei
