Following some collaberatiion on Facebook group Radiosonde UK, we found a workaround for an issue we had with the code not uploading the new frequencies - possibly on on later softare versions of RS41 sondes.

To enter service mode, the probe expects "STwsv", and then responds with the menu and the prompt ">" Looking at the code (line 277), it seems to be expecting the reply "> OK" Removing the 2 conditions in the 'if' statement and it worked (after a couple of reboots) and changes the frequency to 433.800. if ((buf[buflastline+1] == '>') && (buf[3] == 'O') && (buf[4] == 'K')) { to: if ((buf[buflastline+1] == '>') ) {

This workaround was applies sucessfully on another install. I hope this is useful.
