Yes Simon, that is the question.
What options are there to sense an external stimuli from SDR-console? I guess most new computer do not have neither a serial nor a parallel-port to access external stimuli via.
Can the USB-port be used for such a purpose?
USB interface via an embedded Arduino, would that be an option?
Via a USB to Serial-port adapter?
I am not computer HW/SW experienced enough to see the possibilities for sensing an external stimuli, I am afraid. Nor what actually is feasible to implement.

OK,

 

I understand. You need extra frequency-fudge-factor logic, sorry this isn’t available at the moment. I’m off to play in the garden, take hound for a walk and a beer, then carry on with non-SDR coding.

I don't have a problem with console, radio is a FTdx3000 ,I just wondered if it was possible .the radio shows shows 28mhz console shows the true frequency of 10ghz lnb is an unmodified pll type ,under normal use console controls the frequency and mode of the radio ,but using the if of the lnb ,my radio does not understand the 10ghz frequency of sdr console ,if you see what I mean

Hi.
Would it be possible to implement the functionality of a CW carrier tone RF output, in CW mode, when an external closing is made e.g. a CW straight key or the closing of an relay (transistor) from an external CW-keyer? I am looking at the Lime SDR here.
This would facilitate making CW QSO's from the Lime via the SDR-Console. A most sought for function in order to fully utilize the SDR-Console Tx capability together with the Lime SDR for VHF-UHF DX work.

We need a PTT input function as well, preferably in parallel with the CW-key input. An PTT input function will be needed for CW transmissions as well.

Re: Console v 3.9 control radio es'hail

means you receive with an sdr and transmit with a normal rig??

and ... a couple of transverters??

all gps locked or in minimum superstable?? otherwise the setup to be transceive ... will not work and you also may drift a lot

i would say ... using an sdr for rx and tx is MUCH easier as a transverter setup (especially if you have several of them in a row)

receive is lnb to sdr ...(the lnb is already a downmixer)

transmitting is only a power amp needed

only two clocks involved ... receive is stabilized with the psk beacon (against lnb drift) ... so you just have to make ONE SINGLE CLOCK stable ... the master clock in the sdr setup ... (be it a pluto, a lime or whatever)

Hope this is not considered "talking about the rope at hangman's home", but HDSDR allows to go down to 250 kHz and up to 3.2 MHz, which may seem to be a little too much on my laptop.

What about the real advantage to use oversampling to extend the dynamic range of an RTLSDR?

It seems there are no low sampling rates to accommodate low bandwidth
connections. One doesn’t always need 2 MHz. In most cases, 250 LHz is
more then enough. SDR# has them, forcing me to use inferior software.

Re: Satellite things

Ken Alexander
 

There's a risk with this.  FM satellites operate on one frequency that everybody shares, so storing the frequencies in the software is no problem.

The risk is with linear (SSB/CW) satellites that operate over a range of frequencies.  Some linear transponder satellites offer up to 100 kHz of available bandwidth to operate in.  Put one frequency into the software instead of selecting from a range and most people will pick the center frequency, not spread out, and create a mess..  This happens already; you get clutter in the center of the band while the rest of the band is quiet.

Knowing that each transponder has a bandwidth of several tens of kilohertz and then allowing the user to pick a frequency in that range is a good way to do it.  I was very active on satellites, roving through VE2 and VE3 and activating over 70 grids the last 2+ years.  I always operated on "my own" frequencies well away from the center of the transponder and people always knew where to find me.  Just a thought.

My “new” Andrus MK1.5 SDR arrived yesterday as I’d already bid for it.

It was sold as “house clearance” “no PSU” etc so I was prepared for a faulty one as these comments did not inspire confidence!.

Powering it via a double USB lead didn’t trigger a “device found” so I removed it from its case and checked it and soon discovered a very hot 3.3 volt regulator.

There are two 3.3 v regulators and their outputs are split into various supply feeds with lots of chokes and capacitors.

I found one feed had 0.9 ohm across it so removed its filter choke thus isolating the circuitry fed by VCC3V3ETH/AVCC3V3ETH.

The circuitry is chiefly an Ethernet controller so I powered that circuit from a variable supply with limited current and found the Ethernet controller chip ran very very hot at 1.5 volts 1.5amps.

So the KSZ8851SNL chip will need replacing, but not easy due to its tiny size, however I can now power the Andrus from the USB cable. If I press its Reset and HWBE buttons the thing is detected by my computer asking for a USB driver AT32UCB DFU.

Sure enough the Satrian website tells me I need the driver but I can’t find one.

Any ideas anyone?
