you have to do 5 runs in analyzing but you have smaller files (so a bit faster loading time)

we have a few users here who do such recording regularly (and analyze band openings, grey line conditions etc.)

i am quite sure that simon will not explain exactly what is working under the hood ... but in fact all these sdr software do the same things (just with a different user frontend aka gui)

the most differences are dictated from the sdr hardware you use ... be it a direct mixer (0hz if) down to soundcard frequencies (example a funcube dongle) .. or be it an rtl stick (low if of a few megs but the driver makes it a real iq signal) .. or be it a direct sampler with a super fast adc converter ... or an sdr with a transceiver chip like pluto or lime

some good examples can be seen if you look on how gnu radio companion works ... there you see the different building blocks (adc conversion, downsampling, filters, decoding ... sending audio to a sink etc etc) ... in fact these sdr software work quite similar if you have the same fronend (hardware) connected

just the look and feel is very different

ps and i love how the sdrc v3 looks :-) cause you can dock different front end blocks like you like it ... or complete switch a block off

Hi group,
A very basic question, sorry:
with SDR Console, I could record the I and Q signals over the full bandwidth of my RSP-2 SDR, i.e. 10MHz. I could also do 5 recordings of 2MHz bandwidth.
What will be the practical differences when I want to analyze these recordings with the data file analyzer to isolate specific signals?

BTW, I'm looking for a document that explains more and better than with a block diagram the operation of an SDR and the processing (decimation ans so on) that comes under the software (SDR Console in my case)

Dominic,

I tried to use a consistent color scheme based on the default plan that Simon included in the Beta, but found myself having inconsistencies and variations.  I tried to have colors for each use type, dark blue for broadcast, dark red for person to person, light green for marine, dark green for aviation.  I think your light blue was a better choice for marine.  Then I tried to have different colors for the different modes, CW, digital, voice, ...  Next I tried to make sure there was a noticeable change when one band plan transitioned to another.  I tried to avoid layering the band plans, but did it when I thought it was worthwhile, like showing the General class allowed ranges on  80, 40, and 20 Meter.  I just noticed that I missed 15M.  I also overlapped the ISM, WiFi and 13cm Ham bands.

I would be open to working with you and others to come up with a consistent color scheme and a more complete band and marker plan.

Seems very useful, but how do I use this file in SDR Console ?

One thing - you can always use the mouse wheel to adjust a slider.

Subject: [SDR-Radio] Tricky drive level setting for SDR Console to Pluto,
QO100

12 February 2022

I wonder if anyone can kindly help me with a drive issue I am having with my
PlutoSDR and transmitting to the QO100 satellite via the narrow band
transponder using SDR Console please?


Recently I am finding setting the drive level is incredibly tricky. Using
the Tone or Tune functions in SDR Console a tad too much drive level and the
Leila, the satellite's too great a signal level warning is triggered. I
reduce drive until it is no longer triggered and all is OK for some seconds,
then it is triggered again, as if my power is increasing of its own accord.


Once I find an acceptable level by very fine manipulation of the drive
slider but I then find that after a period of reception there is no longer
enough drive to set the Pluto / amp into TX again.


This appears to be a recent problem, as a while ago when I was on the narrow
band transponder with SSB I didn't seem to have so much of an issue.


My set up is Windows 7 64 bit, SDR Console V 3.1, LAN connection to my Pluto
at the base of my 1.8 meter prime focus dish. The Pluto is driving an
Analogue Devices CN0417 pre amp driving an SG labs 20W amp via a 6dB
attenuator, which in turn is triggered by its VOX PTT. The SG Labs amp then
feeds the POTY antenna via a short length of low loss co-ax.


MAYBE the attenuator is between the Pluto and the CN0417, I can't reliably
recall, and I am at work.


My own, novice, thoughts are that to trigger the SG labs amp via VOX is
needing enough drive power to put its output around the trigger point of
Leila. Does that sound feasible? What about the rise in output when TX'ing,
and the fact a signal level adjusted down when operating with Tune or Tone
to stop triggering Leila becomes insufficient to set the ensemble into TX at
the next transmission?


Thanks for any advice. I could JUST get a signal on SSB with only the
CN0417, before I got the SG labs amp. I wanted a good deal more power as I
also run the set up on DATV on the wide band QO100 transponder. Best
regards, Chris, 2E0ILY

Having switched to version 3.1, I now miss the nifty quick buttons "Back/Forward 10 sec" in the playback navigator.
Any chance of getting those back?
(I know that they are still in the "Rec/Playback" menu, many clicks away if you like to be in "Memories")
