Hi All I have just obtained a Heros Tiny Plus-Cat SCR Preselector. All seems to work well when used external to PowerSDR. I have the following issues; -when connected via 12C interface and Flexwire I/O port the preselector does not track the frequency in PowerSDR software. Not sure if it should track ? -when changing parameters on the Heros dialog in PowerSDR the preselector seems to click (indicating relays being activated/changing) but band selection, fine tuning and bypass doesn't seem to be working correctly. Selecting Band A does give some attenuation though I don't think it is correctly tuning 1.8-3MHZ. All other band settings seem to bypass all filtering. The Tiny Plus-Cat Preselector is the latest version using the latest firmware. I feel there is an issue with the control signals between the Flex Radio 5000 to the 12C interface. Does anyone have this working ? Any assistance would be greatly appreciated. Kind regards Tony VK5TT
