User configuration for a newbie??

Brian Bowers G0VAX <g0vax67@...>
 

Hi all,
I am very confused as to how to configure sdr-radio with my Cross country radio SDR4+ 
Is there a “Get you going or how to” file anywhere??? 

SDR is a new concept to me.

Best Wishes

I had my baluns swapped out to favor HF on my USB model. I remember looking at swapping out the TX/RX switch on the mini & it looked much harder. Not sure if I found a replacement part, either.

So there’s nothing in the TX path on the MINI that could attenuate the signal?
Looking at the data sheet of the Tx/Rx switch, the return loss of the
thing is heading rapidly towards 0dB at low frequency, it shows up as
about 4dB at 100MHz. That in itself is likely to see the power falling
as you go lower than 100MHz, by the time you're below 20MHz it is
probably doing a good impression of a short circuit to ground.

The transformers have good return loss at low frequency, and low
insertion loss down to 4.5MHz.

I'd say it's the switch.

Question to Simon: More Identities and ability to clone them?

Lorenz Graßl
 

Hello Simon,

did you ever think about to introduce more Identities to SDR-Console? In my case I use them (or would use more of them) for specific purposes:
1) regular operation (SSB) on QO-100
2) DIGI-operation on QO-100
3) CW-Operation on QO-100
4) WINLINK operation on QO-100
5) Experimental-Setup
6) ...

Each setup has specific waterfall-ranges, radio-settings, waterfall speeds, windows-configs, receiver-pane-settings, filter-variations, equalizer-settings and so on. I would love it to have at least 8 or 10 Identities.

What, independently from that, a great feature would be: the ability to clone one "well setup" ID to a new one to have a good base to modify it for further use. Now we have to start from the scratch when opening up a new ID.

Thanks so much for this fine piece of software you gave to us!

That's interesting that you can't buy US Amazon items in the UK. I regularly buy items like movies, etc from the UK, DE, FR, IT, AU, etc that are just not sold and/or released in the US. However, I did find early on that to get those items, I must logon to that countries website directly, like amazon.co.uk. The beauty of Amazon, is that my US logon credentials (and purchasing options) are also valid throughout the Amazon universe. In the foreign language sites, I have to use Google Translate or Chrome to auto translate to English, but it still works. At most, they may ask to verify yourself through a text message code, but that hasn't been a problem.

it was a few days of puzzling to get all work like i wanted it

that company eks does not exist anymore but maybe you can get a used one?!? (EKS XP5)

the device when pluged in is found in windows as a hid device ... (NOT MIDI!!)

after installing the right driver and config tool it is THEN found as a midi device

with the config tool i had to do some changes ... example the coarser tuning steps (1kc and 10 kc steps) are programmed in console as "range" function (a slider or knob) ... but i wanted them on single buttons so i had to program these buttons in the midi config tool to become a range function ... and on a few button i also added an autorepeat

otherwise to change from 50 % drive to 90 % drive you had to push the drive up button 40 times ... with autorepeat you just hold it long enough

the mapping (setup of the midi config tool) ... and also the midi definitions in sdr console can be stored and so it should be easy also for others to use a similar setup

and ... if you know how all buttons are set in that magic tool ... and in console ... then it is also easy to change settings on your own

the most problem was getting the volume slider and the turn wheel working like it should ... for the volume slider i had to change the midi channel number for that slider (or moving slider would be like criss cross pressing all buttons on the deck ... grmbl) ... ...

turn wheel also was not easy ... it has a touch sensor (so two turn speeds on a single wheel) ... and when configuring you have to change a few numbers in some config boxes in console .... but ... to work right you have to change the numbers with one hand on keyboard of the pc ... while holding the touch sensor with the other hand :-) ... cause when you releaze the touch sensor the configutration is then for not activated sensor

soooooo .. it was a bit longer journey ... but finally i think it is the best 40 euros ever spent :-)

you can get many different dj controlles to work with console (if they talk "midi"!!) ...

what i like is

on most decks you have fewer buttons but lots of turn knobs and also two turn wheels ...(and big size!)

i wanted a single wheel and more buttons so i searched and searched ... till i found that eks xp5 deck

all buttons can be free prorammed to any controller number and midi note ... and they also can be combined together

so LOTS of combinations possible ...

it is not super easy in first view ... but if you know how it works (if you got the "ahaa" effect) ... then it can be done with only your imagination as a border :-) ... even 2 or up to 4 decks can be combined ... (only a dj needs that hi hi)

This looks like a very elegant solution. Forgive my ignorance, is this just plug and play or is there any kind of programming needed to map the midi to SDR C?. If so, would you be kind enough to share the details please? Also, what is the make and model number of the controller so I can try and find one in the UK.

Re: PlutoSDR: TX spurs 23cm and 13cm if TX and RF frequency are equal #adalmpluto

Yves
 

Thank you Simon to look so quickly into a possible solution.
I understood that the AD9363 is capable of TTD, Time Domain Duplex, but that is only a small part of the whole system...
Taking into account that the TX spectrum is cleaner in the 2m and 70cm band anyway, I will go the route of a TX up-converter for 23cm and 13cm. Not sure about an RX frequency conversion yet. 
BTW, as a simple CW keying solution an idea I would like to try to do the keying (shaped) after the TX port of the Pluto and TX a constant "Tone".

Hello,

Started playing around with the HDR mode.

Does seem to help, but am uncertain regarding these:

 

a. Console must be started after selecting the 2 MH Bandwidth option.

    And, only 2 MHZ; no other choices will work.

        Correct ?

 

b. If one changes from this 2 MHz (shows also in Home/Bandwidth) while
playing within Console, there is no way of getting back to HDR mode without re-starting.

        Correct ?

 

c. Is HDR active from the 2 MHz all the way down without any limitations ?

    I question this, as in SDRUno, it seems there are only certain Bands
    or freq. blocks <2 MHz that HDR works for ?

Any other thoughts on HDR usage would be appreciated.

Re: IQ output from Console

Charles Suckling
 

Hi Max

On-air tests today confirm that Spectravue is able to process IQ output from Console set to output to CW Skimmer.

I was able to measure my normal levels of sun and moon noise with my 1.2m dish on 10GHz. 

Example of moon noise displayed by Spectravue continuum mode:



Vertical scale 0.5dB/div.  The wiggles in the higher level (dish on moon)  were me optimising the dish elevation and azimuth. The lower level is with the dish pointed off the moon, looking at just cold sky.

The level of  'noise' in the trace is a function of bandwidth over which the power is summed.  In this example, I used 48000 sample rate for IQ,  giving a 48kHz bandwidth of noise for Spectravue to process.  I see that Console can output higher data rates,  which may allow a larger noise bandwidth to be processed. This would  reduce the  'noise' (fluctuations) and allow it  to detect and measure smaller noise changes. I plan to experiment further  to see what's possible.

I was able, in parallel, to take the demodulated audio output from Console into WSJT-X.  I only have one VAC at the moment (which was used for the IQ stream), so the audio was coupled with a real cable (headphone output on PC into MIC socket). Need to add some more VACs!

It would be great if this kind of feature was available in Console without the complication of having to have another program running, especially if  it could process larger bandwidths of noise.

Hi Simon,

 

i think there are no output filters. See schematic.pdf page 5.

Only T2, C15, C14 could affect the lower HF frequency limit.

Re: Tuning wheel mouse?

I've found this to be an excellent solution.

https://tysonpower.de/blog/reprogramming-a-audio-knob-to-build-a-sdr-vfo-knob

The actual usb volume control (tuning knobs..) are available on eBay very cheaply and are very well made for the money. The case is steel and nicely weighted.

You do need an RS232 programmer to hit the knob with the required firmware, but once that hurdle is overcome you won't be disappointed and I know because I'm using one here.. A nice feature that Simon seems to have implemented in SDRC and that works well with the modified unit is that with each click or depression of the knob the tuning step changes, thus enabling faster or more fine tuning as required.

[Edited Message Follows]

Hi,
I discovered the PlutoSDR for QU-100 operation.
Due to the good experience, I started to evaluate it for terestrial operation on SSB and CW on UHF amateur bands. The TX signal from 6m up to the 70cm band is quite clean, fine at least for QRP operation. But on the 23cm and 13cm band the spur level increases a lot if the RX frequency is about the same as the TX frequency as it is with traditional simplex QSO. For QU-100 operation this effect does not show because RX and TX  frequencies are different. I suspect that this is an effect of internal stray RF in the LO chains of the AD9663 (I think the chip is not designed for this kind of operation). 

Did somebody made similar observations?
I wonder how this issue could be mitigated and whether there exists a possibility today with the SDR console to switch to simplex instead of half-duplex mode?

If all fails, I could still use a frequency converter on the RX or TX side to have the LO frequencies always different from each other above 70cm., or use a seperate RX radio.

Attached I put some TX spectrums, all recorded with the Tune signal at 82% drive, about 0 dBm on the output, 1.2 MHz bandwidth for the radio:

From left to right
- 432 MHz RX=TX frequency, 10 MHz span - clean spectrum
- 1296 MHz RX = TX frequency, 10 MHz span, with spurs
- 1296 MHz RX <> TX frequency by 2 MHz, 10 MHz span, less spurs
- 2320 MHz RX <> TX frequency by 2MHz, 10 MHz span, less spurs
- 2320 MHz RX = TX frequency, 10 MHz span, with spurs (they may be stronger on some frequencies)

Thanks for any suggestions or comments.
