Our group owned Robin regularly misses a beat. In fact, it misses a beat everytime in a certain senario i.e. when at a very low power setting, then increaseing it. It only has to be a slight increase, but every time, it misses a beat I'm sure it has only started doing this since it's come back from it's C of A renewal, but I'm quite new to the group, so I may be wrong. Anyone else experienced problems like this ?
