I took the plunge and bought a second AR-DV1. As many can imagine my original has had to do a lot of work over the last 5 years.
Now I can compare the behaviour of one DV1 using FW v.2107A, and one using 1907B, under manual or computer control at the same time, and hopefully eliminate any possibility of any issues being caused by an individual DV1's hardware.
I can confirm the same random '
No res' message appears on either DV1 using FW 2017A. When that happens the Radio has to be powered down then up, and sometimes the Memories have been corrupted, and only a full Reset and copying back the Memory details seems to work. This does not only happen under software control. I have not been able to tie this down to a particular function being called. There are other smaller anomalies from time to time.
As it is happening with two different DV1's it must be a firmware issue with 2107A. It never happens on either Radio with 1907B.
It may be worth noting that the original firmware (and up to the present) for the
DV10 has had Memory, and locking up issues. Whereas the DV1's firmware has not until now.
In their attempt to get Customers to
buy their expensive latest Tetra upgrade (still will not deal with encoded transmissions) I just have the feeling AOR may have abandoned the stable AR-DV1 firmware completely, and decided to use the already questionable DV10 firmware as the base for their latest firmware regarding both Radios. That would explain the DV1 now being subject to the same lock ups and Memory failings.
Unless you are in an area with a lot of un-encrypted TETRA, then the new and expensive activation process included in the latest firmware (really the only difference than the stable '1907B) is hardly worth considering anyway.
All new AR-DV1's are using the later and flawed firmware on arrival.
The bottom line is DV1 owners should seriously consider sticking with FW 1907B for the time being. No longer available at the AOR Site, but can be downloaded from the AR-DV1 FaceBook Group:-

This is a great pity, as for several years AOR have usually issued well tested and reliable AR-DV1 firmware updates. Of course history indicates AOR will not acknowledge any problems (SIGH), and just treat any mention of it as 'fake news'. Nevertheless they may issue new firmware with these current problems eliminated. Only time will tell.
For those contemplating buying a new AR-DV1, it is certainly a very good device, especially if they install firmware '1907B'. Luckily updating the AR-DV1 firmware is a quick and very easy process,
