Re-tuning
Discovered a powerful pirate station had popped up on the frequency the Niftymitter was tuned to, and so had to find a quiet spot on the dial and re-tune the transmitter.
Re-tuning is easy and simply requires a screwdriver. I used a "trimming tool", which makes the job slightly easier due to being non-ferrous and thus meaning that you can tune to the right frequency with less adjustments (ferrous tools have a capacitive effect on the circuit, and this means that the frequency changes slightly as you take the screwdriver away). These tools are very cheap, and its not particularly difficult to do the job with just a normal screwdriver.
