Hello tkomoski,
Email support@signalhound.com with this exact question. There might be some files we can send you via email to do the update. Ensure you send the S/N with your email, we will have to ensure your device is eligible for the update. We can also calibrate the device (current price is 100 USD) and we could update the firmware in the process. Look forward to your email.
Regards,
A.J.
