Re: Problems with DINAH on Raspberry PI 3+: issue resolved: I appear ot have damaged my DINAH

 

OK at Stephen Smith's N8AR suggestion I went and rechecked the behavior of the DINAH on my Raspberry PI 2 and 3+.

The previous?testing had been:

- worked as expected on Raspberry PI 2:? speaker sound level was high?during transmit even after receiving a squelch signal

- did not work as expected on Raspberry PI 3+: spoundlevel on speaker?channel?was set to zero during a squelch singal?and did not return to normal levels and transmit was suppressed

I moved to the Raspberry PI 3+ because the Raspberry PI 2 USB was unstable with the DINAH, a wifi dongle, and a bluetooth dongle for keyboard/mouse.

I cobbled together a stable test environment on the Raspberry?PI 2 and:

- did not work as expected on either? Raspberry PI 3+: or Raspberry PI 2: spoundlevel on speaker?channel?was set to zero during a squelch signal?and did not return to normal levels and transmit was suppressed

I must conclude that I damaged the DINAH during the testing and that leads to the present behavior.

My apologies for raising the issue and My thanks to Stephen for? his assistance,

We can consider this issue closed.

I am using a DINAH and either a Raspberry PI 2 or 3+ using the Direwolf 1.6 software

When I connect a DINAH to a Raspberry PI 2, the DINAH card output is silenced when Squelch is enabled and then returns to the prior?setting and will transmit properly.

When I connect?the DINAH? to a Raspberry PI 3+, an incoming?signal enables Squelch, the volume of the DINAH output goes down but does not return to normal?when Squelch is dropped.

This means I can receive?fine but can not send.

This actually mirrors a problem I saw on Windows.

I can obviously cut the COS line, but this disables?the hardware check for channel busy.

Thoughts?

Thanks!
