Version3.7.4

Hello to the group, I'm still using V 3.7.4 on my 6400M. Everything works just fine, am I being foolish? I use it as a stand alone, RTTY contesting. Thanks for the advise. 73 John, W2VTV
PS if I do upgrade the software, can I go directly to 3.10?

Any particular reason you haven't upgraded to say, 3.9.19? 3.7.4 is quite a while ago.

Yes, you can go directly to 3.10.10 from any previous version. If you find 3.10.10 unsatisfactory for your needs, you can also go back directly to 3.7.4.

There have been quite a few bug fixes since 3.7. I can't remember when the last of the SD card fixes happened, but that alone makes the upgrade worthwhile.

Well I'll upgrade. Second part of the question, can I go directly to 3.10?
Thanks for the replies, 73

Hi John, there is an issue with 3.10.10 where IQ data used by digital programs has changed. This means that some digital programs are not working correctly. Since you are a RTTY contester, this could potentially affect you.
I normally recommend upgrading, but in your case, you might want to hold off until the fix comes out. I doubt it will take too long for Flex to release the fix.
