a circuit diagramm of his software as building blocks ... to
better understand what is going on .. yes that would be nice
Having one single person as maintainer and using pull requests
(for the other programmers) to add functions (or change small
parts) is what we did in the mchf firmware ...
that worked superb (with a dozen "hackers" around the world) ...
andreas (df8oe) is/was building new fw and puts them on a download
link (similar as simon does when he has a new beta finished) and
all programmers can make changes in the fw (and send a pr to
but i also understand if he want to keep things closed source ...
it is HIS BABY :-)

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
... 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

70cms station working
- Working 2m
- Cleaning the

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
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
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
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

Not much more I can do now .
i can not hear any signal anymore .. why? my
cpu is snoring (fallen asleep cause cpu liad
is very low) :-)
works superb ...
ps .. yes the pluito IS running!!

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