- Using SPF-08 with Elad Duo or S2
Re: Using SPF-08 with Elad Duo or S2

From what I can see, the QSF-06 and the SPF-08 have I2C eproms on their control boards. It appears that the eproms are used to tell a Duo or S2 that a pre-selector is attached to the radio. The SFE-1 Experimenter board has no eprom. That being the case, how would a Duo or S2 know that the SFE-1 board is attached to the radio? That probably explains why I am not seeing any SPI data out of my Duo with the SFE-1 board attached to the DB9 connector.
Can you confirm that the SFE-1 Experimenter board will work with the Duo and the S2 radios? Perhaps the SPF-08 and QSF-06 eproms are used for some other purpose.

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 :

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.
