We also turned the transmitter OFF and ON and the Receiver again OFF and ON while the amp was ON and found minimal pop and excellent Squelch. We also compared it to JOYO and found that although the Rowin is much quieter and sonic ally overall a better choice it had something that lacked and that is the ability to re charge, however as it goes with internally rechargeable systems after a while the internal battery system will fail and at that point you have to throw the unit out, in this case you always insert fresh batteries and you are 100% good to go always.
