I have a Monitor IV and it will randomly drop in volume. Sometimes when it is acting normal it will get a loud high pitched hum while receiving the transmission. My hand will effect the hum when I place it in front of the speaker. I don't think it is my speaker because it does not happen when I use my store voice option. I have seen many post of the decoder having problems, but I have not read any posts with the same problems. it echoes sometimes as well, but i have no idea if these issues are connected.
If anyone has any ideas, it would be greatly appreciated. Thanks, Oopie
