My Win 96 is a registered version. Whenever I upload to the scanner in one bank, the bank that was previously uploaded and working good gets erased. It doesn't matter what I am uploading...conv or trunk. In other words, I will upload to bank 0. There's no problem and is working. I then change the bank to 1 with more frequencies in Win 96 and upload. Bank 1 has no problems and is working but I would find that bank 0 frequencies are completely erased. I would then fill in bank 2 and upload and bank 1 is erased. Is it a problem with Win 96 or a memory problem with the scanner. Or what am I doing wrong? Am I missing a step in saving a bank before moving onto the next one when programming? thanks! Scanner is a Pro 96.
