Re: Using SPF-08 with Elad Duo or S2

Hi Clint,

when using S2 and SPF-08, the External HW tab of the Setup window must be used to set the filters, see below :

When using the DUO (not the DUOr) and SPF-08 or QSF-06, the FDM-DUO Manager window must be used to set the filters, see below :

Hi Neil,


So you can use the SPF-08 without the SW-2 software?  I assume that you initially had to use the SW-2 software to tell the Duo what frequency ranges to use for each band.   Does your version of SW-2 software show the “hardware tab” on the setup menu.  The older versions of software showed that tab, but it has not been there for several later versions.

I have an SPF-08 with my DUO. Works fine in standalone. I configured the filter selection originally using SW2.

Is anyone using a SPF-8 pre-selector with their Duo or S2?  If so, I wonder what version of SW-2 software you are using.  Also, are you able to use your Duo in a standalone mode with the SPF-08 without having to run the SW-2 software.  I have not done any testing with the SPI interface on the radios's DB9 for about two years.  Currently, I cannot see any SPI signals on pins 1, 3, & 8.  I do not know if my Duo's SPI interface is bad or if there is some other problem.  In reviewing the available docs, I am not sure I understand how the SPF-08 could work with a Duo in the stand-alone mode.  Obviously with the S2, you have to use the SW-2 software in order to use the receiver.
