Just forwarding an interesting thread on the above...Steve, K8SP
Hello,
I have the same issue with a new 998 tuner and have talked to MFJ many times on the phone about it. I downreved the code on my tuner to 737 code that we
provided to me by MFJ and it still has the same issue. Hopefully they will get it figured out.
