Hi,

I'm operating RP successfully since a couple of days with 10Watts and made some nice QSOs.
However, I have the following problem:
- on PTT-Out (pin E1/3, DIO0_P) I don't get 3,3V when PTT is turned on via MOX with HPSDR. I always have 0.01V constant signal even in RX mode. So I can't operate RP remotely
Is there a way to redirect the PTT-Out signal to another free pin on E1 since I afraid my DIO0_P is damaged for some reason.
Maybe this question could only be answered by Pavel.

Question:
2) I would like to signal via a LED (outside of my housing) that SDR on RP has been started. Is there a pin which signals this already (except that onboard LED on RP) or can this be implemented in one of the next SDR release?

Thank you for your kind help in advance.

Hi Pavel,

looking on line 646 in sdr-transceiver-hpsdr.c, I'm unsure to add setting for example my new output pin (e.g. *gpio_out |= 0x80, DIO7_P) because tis line is in a switch commented with '/* set rx sample rate */'. Is this really the right place for my purpose?

Thanks in advance.

Roland
