I have been tuning in the Portsmouth and surrounding areas for over 33 years but am now almost totally retired. Certainly for the rest of this year I am taking no bookings, while recovering from recent medical treatment.
I have connections with some other local tuners who may be able to help you, and their contact details are given below.
