Re: 3.1 Betas


That has some good aspects and some bad aspects with the two sets overlapping heavily. Simon would have to learn and practice Linus Torvalds management skills. ("This code looks like s....!") And even then it would wander away from what Simon envisions his legacy to be. It would be nice if the code was setup to become publicly readable but not modifiable without forking the project. Then new front end modules could be built as necessarily yet the main code could be unchanged, for some people, and a springboard for other people.

For myself, I'd be happy with a mid to high level description of the code and signal path through the receiver. What DSP technology did he use to achieve various functionality without delving into the code. "How does a genius do it?" For example it APPEARS that he is taking overlapped FFTs of the whole bandwidth of the front end and creating band pass filters centered on frequencies the user selects for each receiver. One FFT, N windows, and N reverse FFTs, and some other processing before it gets to audio.

if sdrc v3 would be open source (with you as maintainer) ... that would also be nice ... (but i know you will keep it a one man show ... "you are the boss")

the source on github .. and a dozen programmers working together (with you putting the pull requests together to a working exe file) ... similar as what we did for MCHF rig firmware

... i can not do programming (especially not such thngs like sdrc) ... as you know i am more a hardware builder (reason why i did not send you lines of code but a feed)

enjoy the weather ... do some garden (or antenna) work 

... or watch the ladies on second tee (big grin)

if you have your feed installed .. please give some (hopefully positive) feedback

I could do lots of things, including:


  • Getting a new POTY installed
  • Getting my 70cms station working
  • Working 2m Tropo
  • Cleaning the gutters on the house
  • Cleaning the house
  • Mowing the lawn
  • Watching the ladies play gold in front of the house (2nd tee)


You could learn the art of software engineering 😊 .


Will be good weather this week.

You could add auto engage for geobeacon in a 1 to 2 kc wide search window... (my tcxo modded lnb drifts maximum 1kc over the day)...

And to try it on your own.. Mount your donated feed (has a similar lnb mounted inside wjth a 0.2ppm tcxo) 

On each start of sdrc v3 i have to catch the beacon and engage locking (press "play" button in beacon window) 

An auto engage would be a nice add on..

And a positiv feedback how well the modded lnb works also would be superb ;-)

Do not wait until winter.. Or you will maybe tell me that it is too cold outside for antenna work (grin)

You wrote you can not do much more... Ok looking on performance you are right.. Cpu load is now very low.. Only thing you can do is some cosmetics.. Solve a few wishes from the todo list.. 

What about adding the values from the power amp to the meters tab in tx box?!? (now meters tab is just a placeholder)...we have already discussed that.... Where do i find the hidden switch for dab decode (joking a bit) 

And what really would be superb.. A backup and restore file for ALL settings.. So if you want to install sdrc v3 on a second pc with similar settings that you can import the settings file from the other pc... With all settings saved in a single file and an import function. Be it filter settings or equalizer or agc or whatever

"do you really want to import these settings?? Yes/no" .... And if user press yes that the setup then is like on the other pc... No idea how complicated that is... But i am sure many users would like to have such a backup and restore function... 

What do others think?? What is the most needed feature in sdrc v3??? I am quite sure if you ask here in the group a lot of users would answer backup and restore

works superb ...

Thanks – first feedback. I find the sample rate from the RSP can wander a bit until it warms up, then it’s fine. Oh I had some bad code in the SDRplay support…

Hi Simon


I downloaded and installed the latest Beta kit. Latency and dropouts seem much improved with my Sdrplay RSP2. Thank you.
