Thanks Jim,

I studied things a bit more, and found that the D2700MUD supports something called eUSB.
An embedded USB flash drive which fits over a specific USB header on the MoBo, and has a locking screw.
Found some 1GB eUSB boards on eBay and will give that a go as the system drive.


D2700MUD has 7 USB ports.
4 external ports on the back panel
3 internal ports via headers on the MoBo.

I'm building two systems with 12V power supplies.
Will report on how things go / photos etc.

I have no idea whether the PCIe SSD would work.. You can always try it :-)

If you are intending to use that many URI's you should probably consider using chan_simpleusb
as to not overtask your system. I hope it has that many on-board USB slots.

Hi,

I've read the Limey docs, saw the D2700MUD was supported and got one.
Now building the system, but not with a lot of Linux exp.


Drive Question:
I could use a 128MB CF card in a CF/SATA adapter, or 

I see the D2700MUD board has a Mini PCIe port where I could put an SSD.
The SSD would be a clean cable, all-components-on-the-motherboard system and looks attractive.
If I used an SSD, would I still be able to use the standard Limey binary/image intended for the CF?



RTCM vs URIx and system scalability/performance:
I'm aiming to use this system to control a co-located VHF and UHF repeater. (ICOM FR-5000/6000)
It may also have an additional repeater or link added over time - possibly 4 radios.


Do I need to be concerned about performance of this D2700 system with 4 radios?
Is there a performance advantage in using the RTCM as the radio interface in that it seems to process COR in the RTCM rather than n the PC?



Any hints or tips would be appreciated.

Thanks,Randy
