Hi just my thoughts on call in channel, back in the day 14 was the breaking channel, 19 was for mobiles, locals throughout uk would play music and block it.
Today 14 and 19 is blocked with hash and lack use, maybe my new wire antenna will change that?
10/4 from Cobra or possibly Fazer who threw in bin Turner Expander 500 and Shakespear Bigstick DOH.
Suppose breakers need a frequency for place of contact.
