DSP red light coming on at max load

Administrator

It's official: we're running out of DSP cycles not just during NR on/
off but also under worst-case load.

I get a continuous DSP red LED and distorted audio (with a buzz) under
the following conditions:

CW
CWT on
NR on, set to F1-x
DSP NB on, any setting
FIR IF filter (WIDTH > 500 Hz)

Turning off any of these kills the red LED.

I also get a red LED when turning NR on/off even if the DSP is not
turned on.

So I need a workaround until you get back. One thing I could do is
defeat the CW decoder (and CWT) if WIDTH is set > 500 Hz. Other ideas?

tnx
W

Interesting.

What exactly is a DSP red LED?
3.41

73 de W6BK

under these conditions, I get no red LED and no apparent problems.

This was not intended for the reflector. Sorry for the bandwidth!

Lyle and I will come up with a fix and get it into the next beta
firmware release. Fortunately he's coming back from vacation soon :)
