@glyn.hudson - I have just sat down to add a 27R burden resistor to a batch of 30 emonTx’s and found the holes intended for this purpose are clear of solder this makes a huge difference when fitting additional burdens.
It sounds like a very minor point but it’s definitely worth a mention because this is one of my pet hates due to previously having had to resort to tacking the additional resistors to the back of the pcb rather than fitting them “through hole”, I had tried desolder pumps and wicking, even bought a new iron but it was next to impossible to fit them properly.
It was a very clear change on every board in this latest batch so I hope it is a change thats here to stay and future batches are the same, as it makes a big difference. It is quicker to do as it is less fiddly and a better result, Thank you!!
