A.E. Volvach (CrAO), A. Pozanenko (IKI), L.N. Volvach (CrAO)  report on 
behalf of IKI-GRB-FuN:

We observed the field of GRB 200729A (Evans et al., GCN 28165) with 
RT-22 telescope at 36.8 GHz starting on July 30 (UT) 14:12:00 i.e. 0.774 
days after trigger.
We do not detect radio emission in the enhanced XRT position (Osborne et 
al., GCN 28168). This is in agreement with non detection by VLA (Hajela 
et al. GCN 28181). Preliminary result of the observations is following.

Date       UT-start UT-stop  OT      Upper Limit (2 sigma)
