Despite useful advice from other users, I have not been able to fix the NPL R100-40T, NPLE, and the possibility must be considered that it will not work again. I will continue attempting to fix it as I receive fresh advice, but certainly it will not be working before 10 January 2001. NPL can make available BIPM time transfer format files from a multi-channel GPS receiver (TFS102). Please contact me to request these, as they are not automatically published yet. Also, I will commission our Javad Legacy receiver to supply dual-frequency code and carrier GPS and GLONASS data, but this is unlikely to be a reliable source of data until the end of January 2001 (due to annual leave, and deadline constraints in early January). I apologise for this inconvenience, but it is unfortunately beyond our control.
