[hpsdr] TAPR Hermes and Alex Filters

[Kjell Karlsen]

Hi Roger.

The connector on the bottom side of Hermes is for Apollo PA/ATU and do not  
work with ALEX as you have found out.

Hi All,
A note for the owners of TAPR Hermes who want to use the Alex filter pair.  
It is not possible to get them to operate when plugged into a 10 pin  
header soldered into J32 position on the non component side of the PCB.  
This is because the footprint of J32 has been copied instead of being  
mirrored form the component side of the PCB for the non component side.
The only way I could get them to operate was to solder the header onto the  
component side of the board, the connections are then in the correct  
orientation. They are so close together that you have to route the ribbon  
cable so that it leaves the plug on opposite sides. (if you have an ANAN10  
PA fitted). I hope I’m not repeating anything already documented, I  
couldn’t find anything referring to this.
Excellent SDR, no complaints, only slight problems in the beginning with  
programming and firmware.
Regards to all,
Roger (G4KFZ)
