Subject: [Repeater-Builder] Hello
Guys we have a Radius GM300 repeater. It has a good location.And hardly mounted
there. Now it takes some noise.And sometimes self tx by hours.We know we have
to set the squelch by programming. But I wanna know is there any short way to
increase the squelch manually ?
