@Roman

Can we get a bit more info about E-Coder2, please?

In particular I am interested in:
- Does it board the same codec as DX or different one?
- If used with DX, how the audio streams are distributed between DX codec and E-Coder2 codec? (i.e. mirrored, independent, etc)?
- Any amp on board? (might be handy in pileup operations, when I have to reduce RFgain to 75dB or less)
- if CW paddle plugged into DX, but audio controlled via headphones plugged into E-Coder2 - will be there a delay or any kind of compensation introduced (or will be introduced in ESDR3?)
- is MacOS missing from list by mistake or it is definitely not supported?

Thanks!

Actually, one thing I would like to ask for - is it possible to make selective value for StepUp/StepDown option in E-Coder? At this stage I have to "click-click-click-click" if I want to go from 5Hz step to 100Hz step. And what I mean by "selective value" is the ability to predefine "click step" so, that I can go by one click UP from 5 to 100 if step 4 selected (and vice versa).

Hi, Pavel.
To your questions:
1. Yes, E-Coder2 has the same codec - CS4272.
2. The audio stream you hear in the SS2DX (or any other TRX) is the same as you hear from the E-Coder2. In this situation the latency between TRX and E-Coder2 is the same.
3. No, there is no additional amp onboard, the signal volume is the same as the one you hear from the TRX.
4. In E-Coder2 we've implemented its own CW core, which was done to minimize latency, so you won't get any latency in any situation.
5. Thanks for pointing it out, it was a typo.
6. In ESDR3 we've removed excessive step values (higher than 100 Hz), in the future, we might consider the selective step as you've mentioned.

Great, thanks, Roman, much more clearer now.

Could you, please, consider either:
- bring amp on-board for future e-coder HW version,
or
- extend Volume in ESDR3 to +dB (+10+20 would be enough). Currently the problem is that in some situations, when RFgain need to be brought below 70-75bB, then max level of Volume (0dB currently) is not enough for suitable audio output level. I have tested this with different kind of headphones. Headphones with in-build amp are certainly, do the job, but those have their own disadvantages. Hence, it would be much nicer to have native tools.

Also, the additional feature E-coder nice to have is CW speed. As this is ESDR function, I would appreciate if you put is into the feature request queue.

Thanks!

Hi, Pavel.
1. Pardon me, I was wrong, there is an amp, actually, there are two chips that amplify the signal for the Mic and headphones inputs.

2. There is a list of the functions we plan to work on first, it's published on the ESDR3 page.
When all of them are implemented we'll put out the list of suggestions and decide what should we do next.
I'd like to do a poll, where we offer 7-10 functions and users decide what should be added first.
