9 times out of 10 when I'm given a squawk, I'm also given a QNH. I was taught that reading back both comes before dialling in the new squawk. If I don't write both down, 9 times out of 10, I will have forgotten the squawk by the time I've read back the QNH, and certainly by the time I've reset the QNH! Others may have better short term memories and recall though. I have to say that modern transponders with buttons for the numbers are a huge improvement on ones with dials. Worst are the ones where you have to press a knob to select the digit, turn it for the digit required, press again for the next digit etc.
