Transponder repair - I can personally recommend the services of Jeff Chandler at Transponder Services in Brisbane, Australia www.transponderservices.com.
I've had batteries and also damaged cases replaced and found the
service to be extremely quick, generally the transponder is repaired
within a day or two of receipt and despite having to send your
transponder to the other side of the world the whole process normally
takes less than 3 weeks.
