Hi guys, after a very bad bike accident and an extended time in hospital (4 months) i now feel like talking to people, i'm VHF/UHF only because of the woman upstairs, so, i brought a Kenwood TH D7E thinking i could do some FM satellite work from a chair in the garden, but, I can't alter the squelch level to 0, I have tried a master reset but that sets the squelch to defat of 2, if I get RT Systems programming software can I use it to change the squelch level to 0, cant get the screen light to work either but I can live with that.
