Hello PGA,
Are you in the United States? If so, please email support@signalhound.com and ask for shipping instructions for a repair unit. I will verify that we did not miss your email. If you have already sent an email, I apologize, we may have missed it. If you want to provide your email address in the forums I can ensure we send you instructions.
If you are outside the United States and purchased through a distributor then you will need to contact your distributor, and they will give you instructions for setting up a repair.
Regards,
A.J.
