I notice in your parts lists you specify Carbon Film resistors. Is there any specific reason for this as most people seem to think Metal Film resistors give more consistent results?

I used Metal Film resistors as the local shop didn't have Carbon in 1/4 watt.

Thanks Bob. The TX board specifies a 380 Ohm resistor can find a 383 but not a 380. Did you find this?

No I didn't, I actually used 360R and the resistors are specified at +/- 10% so you'll be right.

I think that's for the SHT22 temp sensor (or another device on the IC2 line). I used the DHT22 so didn't need them. I brought them though, just never used them and they were like 10 cents each.

Thanks Bob, now I understand.
