TW-4100A Tone unit

[jose miguel]

I have mounted a Tone Unit TU-7 from Piexx in my TW-4100A radio and it only works on the UHF band and not in VHF. all resets and tries have been made without success. Has anybody any idea of what happens. Thanks. Jose Miguel. ea4bqn

Hello Jose,

If I'm not mistaken you'll need a separate CTCSS Encoder / Decoder for VHF and UHF.
