How do we tell which Generation of SunSDR2 DX we have? I have seen the "Hardware modifications" section on the SunSDR2 DX product pages.
My serial number starts EED 06121XXXXXX which is not listed however EED060121XXXXX is which is suspiciously similar! And wondered if any are applicable.
PCB revision 11 and PA Version 13 rev2.

Hello,
You are citing incorrect serial number, what does ESDR2/3 tell you?

My Serial appears to be as I have stated above? EED06121000XXX (Last three numbers I have replaced with XXX. Please see screen shot of EESDR3 also. Many thanks.

OK, that serial number doesn't exist in the books.
You are correct, the serial number for the 4th batch (Gen3) goes EED06012100XXX.
I don't know how it's possible, nevertheless, I agree your TRX indeed looks like the one from the 4th batch, thus some mods are applied to it.

I have just checked the box it came in and on the box it is listed as as a Gen 3 receiver EED06012100XXX. Has ESDR3 mis-read the serial number somehow??

ESDR3 cannot misread the serial number, most likely this serial number was inscribed in the firmware of this unit.
This makes your SS2DX sorta unique)

Hi Roman,

Rather than start a new thread, I'm also interested to know what Generation my SunSDR2DX is, my serial number starts EED06202100xxx
Also do you have a list of changes during each generation?

Many thanks.
Dale

Hi Dale.
Thanks for not starting a new thread)
Your SS2DX is Gen4.

Further to discussions regarding my odd serial No. I came across a Facebook post of someone else that has a serial No. which starts EED06121000XXX like mine. I have attached the screenshot which was shared on the Facebook in May last year. . Serial No is in the ESDR3 window bar top left.

So perhaps my radio is not so unique after all! Perhaps there is a batch of Gen 3 radios with a zero missing between the 6 and 1?

I also further investigated this situation. Indeed, there is either a batch or more likely part of the batch with a changed serial number. Either way, it's OK.

Good morning,
Since the subject is addressed, which lot is mine part of?
EED065119001XX

Hello Rome,
Many thanks .

Hello,

What is the Generation of this device ( EED06202100607) ?
I Have issues with hard disconnection during transmission after several minutes (doesn't looks high SWR or temperature issue) and that is really anoying. I'm using 50 to 80 watts max most of the time.
