This is not a huge problem but is there anyway to edit the software for a GMC-320+. A friend of mine (Cody Reeder- Cody's Lab) made a video on his uranium ore collection. When he got tested his highest sample +50,000 cpm it would reset the cpm and go back up and do the same thing. https://youtu.be/xbOt8Au6thY

No, they won't give us the code. I asked for the same thing earlier.
I have made the suggestion to change to CPS if the value is over 65535 cpm, which is the current limit
ATM you can simply add the next cpm value to the 65535 and have a proper reading. This works.

The 65535 is standard integer data type in software which takes two bytes space to store. It can be increased to 4 bytes data long integer type, which can handle 0 to 4,294,967,295 CPM. I think that is more than enough for this level Geiger Counter.

It needs more CPU power, memory and time to calculate the data. But it is doable.

Currently the software version is V4. Expecting V5 should address this issue.

Cool! Thanks.
Can you get rid of the "ySv/h suddenly dropping" problem in v5?
And the broken average values in timed counts?
Is there a Roadmap or something to see what will change?

The uSv/h dropping problem already fixed in current version software. If you want your unit to be updated, please contact support@gqelectronicsllc.com.

V5 is the next model and it does not have exact release date yet. It should improve many from V4.

Hm. I thought I had the newest. What about all the new threads with this problem?
OK I'll text YOU? later.
