Hi,

Sorry for not answering sooner this week but I was on the field without 
a reliable internet link.

So far, this is the version I use:
- The HackRF board is one from the kickstarter batch:
	- Board ID Number: 2 (HackRF One);
	- Part ID Number: 0xa000cb3c 0x00584735;
	- Serial Number: 0x00000000 0x00000000 0x457863c8 0x26466d1f.
- The HackRF software is 2014.08.1 & come from the official Fedora 
repository.

On another subject, I was able to test this week my hackrf board with 
firmware 2014.08.1 using the dfu trick. The result are great ;)
- Work well under 10Mhz with Ham It Up board v1.2, even if she was not 
as good as the perseus (but this was expected).
- Excellent result for the VHF/SHF bands, and she was quite usefull 
when we needed to replay some burst for futher analysis with our R&S 
equipment.
- Nice result for radar analysis (using hackrf_transfer & baudline) in 
the UHF/SHF band.

Thx

Bernard
