I can now confirm: The full and complete interconversion of a DFR7 US model to a DFR7 NZ model process has been developed, fully implemented and tested.

The main features this firmware upgrade bring are: Adds full Ka band segmentation, also has K band segmentation (2 segments). It also extents the lower K band scanning range for segment K1. It also adds extra gps lockouts.

The conversion files needed will be released soon. However, these will need to be provided with a very clear set of detailed instructions. I would also like to test a few additional refinements. I would also like someone to first test the new USA/Canada gps update.

Unlike for the R3 US <-> R3 NZ and R7 US <-> R7 NZ firmware interconversion we have already completed, the DFR7 conversion is more complex because there are three separate files that have to be installed. THERE IS ALSO NO RECOVERY OPTION on the DFR7 upload tools. Therefore great care and caution will be needed when applying the update.

Also note future GPS updates will have to be uploaded in the Uniden NZ gps data format. These again are fully supported with the release and will be made available.

Great - do you think it will work on the older LRD950 that could also run the latest DFR7 US firmware ?

This is fantastic news! Will the firmware be extended to the DFR6 as well?

Well done @Mithheru. There will be a lot of happy users who are after this upgrade. Another piece of the puzzle unraveled.

Looks like the DFR series has not been forgotten - full marks mate

Congratulations. You did it, your efforts are not wasted.
Lower K band scanning range feature must be in every DFR6/7.
I'll ask you some details about the process.

It is obviously early days. I also do not have a LRD950 to hand. However, the chances are looking looking promising as we already know the DFR7 firmware can be applied onto the LRD950. Perhaps if someone has an older unit lying about that perhaps no longer works properly they could send it to me for testing. At the end of the day, I don't want to give a definitive answer, until I know it is safe for others to repeat the process.

Another good question. I don't have a DFR6 to hand, and have not yet looked beyond the DFR7 at this stage. I would probably need to think about that a bit more, but likely would be easier to convert than the DFR7.

You cant lower the frequency in US units. They are crystal controlled and the crystals used in the US units bottom at 24.050. The only true way to lower range is changing the crystals.

Blulink NZ (the official distributor) has offered to convert US DFR7 units to NZ units by uploading the NZ firmware with their software tools for NZD 200.

I guess testing will tell if they actually change any hardware such as the crystal.

A DFR7NZ for NZD 649.99 vs a US model that BuyDig was selling for USD 120 at one point (I'll be testing mine).

I would agree with you in the case of the R3. I will see if I can take a screenshot with the lower range of the converted DFR7. The DFR7 obviously uses a different crystal than the R3. Was firmware limited, not limited by the crystal.

Indeed you can and here is the proof the DFR7 US K band scanning range was firmware limited:

23.96.jpg
24.04.jpg


Sorry, the images are a bit scewed. Hand to bend the detector and dashcam around to get screen in view.

Anyway, here is the conclusive proof. Turned the K filter OFF. Went looking for low K band source previously detected on the R7. Sure enough the converted DFR7 now detects this same low K band signal!

Sick of here...
I thought these older units were tuned via screws not crystals...

I still have my dead lrd950 (which incidentally is detected by plugging into USB on a PC), am happy to donate it if you want to try, it might work, it might not depending on if you can trace the power fault.

No worries, will send up. Seems strange that the R3 loses the ability to detect the lower ranges, I assume this is a hardware limitation and not simply firmware / programming limited?

I can not tell you what great news this is... fantastic work! I'm so looking forward to turning off K band segment #2!!!

PS- Is there a list somewhere that outlines what segments belong to what frequencies? I note the DFR7NZ manual online doesn't.

Yeas, the NZ manual just appears to be the US manual.

I'm assuming it may be the same as the R3 ?

Ka 1 : 33.399 – 33.705
On/Off
Ka 2 : 33.705 – 33.903
On/Off
Ka 3 : 33.903 – 34.191
On/Off
Ka 4 : 34.191 – 34.587
On/Off
Ka 5 : 34.587 – 34.803
On/Off
Ka 6 : 34.803 – 35.163
On/Off
Ka 7 : 35.163 – 35.379
On/Off
Ka 8 : 35.379 – 35.613
On/Off
Ka 9 : 35.613 – 35.829
On/Off
Ka 10 : 35.829 – 36.001
On/Off

Awesome, thanks. Do you have the K band segment freq's too?
I'm going to guess it's something like
K1: 23.900-24.110
K2: 24.111 - 24.250?

Thanks

Thank you to everyone for their replies and comments on this thread.

Thank you especially @winterbrew for testing the update and checking my instructions.

Therefore the release files and instructions for the DFR7 conversion are now attached here. Please be very careful, and ensure you follow the instructions exactly.

I have also attached the latest build gps database for the USA and Canada. This is the corresponding latest Uniden NZ format file (V1_10USAC) as listed on the thread here:
