Re: [Elecraft] K3 DIY DSP Rev D - please elaborate
...so besides the LPF, what else is different on the DSP D board? I don't think I've seen any elaboration anywhere. I've asked this question before with no answer so far. I'd like some kind of 'sales talk' so I know what I'm getting. It's really good - buy it. is not enough.

By firmware release notes, do you mean the comments associated with the order for the K3DSPUPGD, Don? If that's a yes, then this should settle matters because it says: Improves low freq RX/TX audio response below 300 Hz, and adds a Low Pass Filter (LPF) that rolls off RX audio above 4 kHz. Thanks for your guidance on this, Don. A Happy New Year to you and to all on the reflector. 73 DaveL G3TJP __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 DIY DSP Rev D - please elaborate
David, Yes, that answers it about the DSP board upgrade - there will be a note there if there is a hardware change that requires updated firmware to realize the upgraded function. Normally, the firmware is backwards compatible meaning that the updated firmware will run on K3s without the hardware upgrade. I was really commenting to the gentleman who seemed to be having a problem locating documentation about what was included in each firmware release (upgrade) - perhaps I misunderstood his question (statement?). 73, Don W3FPR David Lankshear wrote: By firmware release notes, do you mean the comments associated with the order for the K3DSPUPGD, Don?

OK...so besides the LPF, what else is different on the DSP D board?

Gleaned from this reflector, I'm only aware of the lowering of the bass rolloff frequency. Elecraft and W9AC did it in different ways, although only W9AC's changes are published. 73 HNY DaveL G3TJP OK...so besides the LPF, what else is different on the DSP D board?
