I am trying to use the attached three files (posted by
John Malsbury in an earlier post
http://lists.gnu.org/archive/html/discuss-gnuradio/2013-02/msg00050.html ) to work on TDMA in Gnuradio. The only difference is that I am using GPSDO kit, instead of external PPS/REF Clock. When I run tdma_radio.grc, I get the following error. Could someone please comment how can I fix the issue?
