How can I find out if my MB-1 is in this category?
***** From the MB-1 Manual *****
This applies only for the transceivers from the first and second batches
(manufactured before April 2016).
We recommend to turn off the transceiver only with the power button, on the
front panel of the transceiver.
Turn off the transceiver, by turning off Windows in the Start menu, may lead to
Roman will probably reply. If not, email your MB1 serial number to EE.
It is good practice, in any case, to safeguard your precious radio by first using the software power button to turn off the SDR and follow that with closing ESDR2 and then shutting down Windows as a last action. It becomes a habit quickly adopted and may save you from a serious problem.
My MB1 is later than April 2016 and yet, once when I shut down Windows first I had the strange situation that the MB1 was locked on with panel lights glowing even though it should have been powered off. I was able to rescue it but never again......
A note regarding serial numbers for MB1.
It is worth checking that the back panel serial number corresponds to the one displayed in Option Software.
To check the one held in software go to OPTION/DEVICES/SDR Info.
The one displayed in OPTION/SDR Info is the CORRECT ONE to contact Roman.
My serial numbers are different.
No sorry Hans Christian, my reply was a little bit misleading.
I turn off the SDR with the red power button in the software. Then close ESDR2 (and all other software of course). Then shut down Windows with the MB1 front panel power button. Don't use the Windows own shutdown.
It sounds like I'm being severely prescriptive and I dare say that in most cases no harm will come of whatever method you choose. But to me the above seems like good practice and I did have that one-time glitch that I don't want to tempt a repeat of. Vasily also told me when I first got my MB1 to use a logical clean shutdown as above. I think its the safest method.
