CHPG, RGDG : Firmware downgrade

Due to doubt about the validity of the Doppler observations in Rinex, a firmware version downgrade to v6.16 was carried out for RGDG et CHPG station. All Trimble Alloy receivers in versions 6.20 and 6.21 being potentially affected, other version downgrades are possible soon. The new sitelog is available on the page of each station.
