Hi all - New to the forums but a big fan of the SunSDR2 Pro & ESDR ...

Is there any movement on the expected release date for ESDR3?
Apologies if this is covered elsewhere but I can't seem to find any info on it.

Not on release date. Yet to start, there will be some testing beforehand. A video dated 24 February outlines the latest news:

Hi,

I would like to ask info on 2 issues.
I test SUNSDR2 with 144MHz transverter, IF= 14MHz.

1. Will transverter mode send 144MHz freq info over TCI? (So that logger can show skimmer info on band map?)
Note: I will use SDC skimmer function. Currently (with ExpertSDR2), SDC receives freq. with 14MHz, hence no skimmer info is shown on logger bandmap.
2. Noticed, passing 14.350 (upwards), the filter setting changes, however in 144MHz (transverter IF on 14MHz) I am still in the band. I suppose it is related to the 14MHz band plan. Will ExpertSDR3 with transverter setting disregard the 14MHz band end? Is there way in ExpertSDR2 to set the same filter setting for 14.350-500 range the same way as in 000-350 range?

Thanks

Thanks for the reply - ESDR3 looks really smooth operationally & the Transverter functions are what I need - even more eager to get my hands on a copy now ...

For the past 10 years I have been using a SDR from Flex and now Apache Labs, and have just now got a SunSDR2 Pro and enjoying it very much. I have a request for the upcoming ExpertSDR3 software, I need a Check Box to reverse the mouse scrolling wheel. I use a track ball that has the scrolling wheel around the track ball, when you turn the wheel clockwise the frequency goes down (so it tunes backward). The software that runs on the Anan and KE9NS (old Flex radio) has this feature.

Thanks and 73,

Joe N9VX

Hello Joe

you sounded good the other day

I would suggest you move this comment to the WISH LIST Section

take care- Rick

Mouse scrolling direction is reversible in Windows via a Registry edit. I do not know but I presume this would also reverse the trackball scrolling as well. It's not as elegant as getting it into SDR software, since page scrolling will also be reversed, but it can be done today against a potentially eternal wait for ESDR3 inclusion.

Has anyone gotten a reply on whether SunSDR 3 will allow user to tune AGC parameters such as AGC threshold like Flex? This is paramount to tweaking your receive for optimal'quiet audio when doing weak signal voice work.

The last proclamation about this was no, some time ago. There did not seem to be the understanding that AGC is like a window with a bottom and top. The top being the overall gain and the bottom being the threshhold. They had this in ESDR2 1.2 then clamimed RF gain, to be called AGC gain in ESDR3, was the same thing. However, maybe it is coming since there have been hints at a 'pro' version of ESDR3. Quite why you would split the version when you can simply have it all in one and let the non-contest and non weak signal Dxers turn off what to them would be the more complex and unneccessary functions I do not know. But the bottom line (not just in AGC hi) is that we might just get full RX optimizations.

At one point one should consider what a rig can or can't do.
If it can't do, it isn't the rig for you (actually read "me").
I stopped evaluating the rigs for what one day they will do.

why do you need to reduce the functionality of ESDR3 ? Was it really impossible to move the functions of the ESDR2 program to the ESDR3 program without touching anything, add and improve some functions ! ESDR3 reduced the AGC function in the receiver , in the transmitter reduced the number of bands in the parametric equalizer not only do you use a ready-made plugin in the new version, you have also removed the output signal level from this equalizer !!! www.instagram.com/p/CGSONzxDxmg/?igshid=u804r1tic2oc

At one point one should consider what a rig can or can't do.

But the point is, as with all SDR, the hardware is capable and is driven by the software. It can do it and does do it in previous versions. Then actually if one day it did do it then surely it must be possible for it to continue to do it (without having to revert to old software which I have done on several occasions to take advantage of AGC-T and be able to hear weak signal CW DX).

I do not think anyone is saying it is not the rig for them. I trust you are not saying that of me. I have owned the MB1 for 5 years and compared it to several other radios in that time, none of which I still have. But it is not unreasonable to ask that in a major re-write of the software, that the opportunity is not lost to make the most of that effort.

Of course, it is not in my habits doing "personal" appreciations. Maybe my bad english could make think the opposite and I am sorry for this.
I was really talking about me. When I started playing with the EESDR rigs I was just leaving the Flexradio world for a similar reason. Lot of frustations for this or that missing feature, maybe in the mean time things are different in Flexradio, but I don't care it anymore.
The lesson I learned with the SDR rigs is that they are mostly a iron block unless their software enable their features. It is all there. You can have a 1000Hp engine but if you don't have the accelerator pedal you can't run fast.
I am a software developer and now I wouldn't like to be in the shoes of the EESDR guys. Now they have the heavy of a lot of customers expectations and I wish they'll end the first V3 asap. Until than, for what I can see from EESDR preview, the AGC settings will be missing.
I like very much the new software, it is futuristic, multiplatform, remotable and it is the best in terms of "software technology" but the words of Vasily about the needs of all that AGC controls are questionable: if you are a contest operator you really don't care a lot of agc settings. As he said in the last video, a simple FAST-LOW settings are most of the times ok. If you ear a station you'll work it otherwise you'll go on with the next one. But if you are a DX hunter, you can bet you have to play just with the agc controls and if it needs with APF/NB/NR and so on.
It is just my experience until today, maybe other can have had different approach with the DX.

Lastly I agree with you, it is not unreasonable to ask that in a major re-write of the software, that the opportunity is not lost to make the most of that effort :so_happy:

I can't imagine anyone getting to sample a functional AGC-T adjustment and then ever wanting to go without it again. I'm a weak signal phone operator (Mostly SSB, some AM) with adjustments to RF gain, AGC-T, maybe a smidge of NR you can listen to almost NO noise level and have signals absolutely jump out of nowhere. Once I got used to this on Flex/Anan SDRs it was so frustrating to listen to even the best of knobbed radios again because you couldn't fine-tune the noise level to this degree.

In the latest SunSDR3 video they did say AGC parameters would be adjustable (maybe in pro version?) - but didn't specify which paraemters. I personally have seen enough youtube comments, posts on forums, etc. about this AGC topic that surely EE has as well. They don't ever seem to acknowledge the topic in great detail, perhaps the way they managed this functionality in previous versions poses technical challenges with 3.x platform?

AGC-T is available in ESDR2 1.2 and, although on a global rather than per band basis, works well. For 160m for me it is essential and I often change to that version as I did last night for the very weak A25RU, whereas version 1.3 with only RF gain does nothing for the signal to noise ratio no matter whether you raise or lower that gain. In 1.3 there was insufficient S/N on the A25 to hear well enough to call.

But then EE seemed to doubt the efficacy of this parameter so instead of building on what they had, they removed it. There cannot be technical challenges to re-implementing it. It does concern me that their lack of experience in on-air activity equates to a lack of understanding of what is required for the receiver, especially in the modern world with its plethora of competing electrical devices adding to band noise and subtracting from usability and enjoyment.

However, although we will not see AGC-T in ESDR3 at launch we can, I trust, look forward to the day when it is and the 3x platform becomes more than just new remote, transverter, duplex and a cosmetic makeover.
