Tempted! There is rumour of a firmware upgrade for the BG7TBL device to fix that frequency error problem. I have emailed BG7TBL to see what can be done. I'm reluctant to write it off because the OCXO is supposed to be quite good. Meanwhile one of these has been ordered https://www.tindie.com/products/nsayer/gps-disciplined-ocxo/ It has a choice of four output frequencies, DIP switch selected and one of the options is 100kHz which would be ideal I think for an LF receiver. -- Paul Nicholson --
