I tell you... sometimes it's as good and sometimes even better than my Wellbrook.

Hi Curt. Thanks for taking the time to fill in the blanks. It sure does not get to be a more simple installation than what you have described. It is interesting what differences exist between your setup/situation and others who swear at their probe antennas? You have peaked my curiosity to the point where I will just have to give one a try. I have several downstairs.....time to get a couple installed outside. Thanks again.

How long and what kind of coax was feeding the antenna? I used RG6 coax approximately 75 feet long.

Laying on the ground or underground?  The coax was mostly buried.

Did you use any CMC on that feedline? No chokes were used.

If so what was their composition/design?

How about grounding of the antenna (length and gauge of ground wire, length of ground rod, type of soil)?  This installation was not grounded.

Bias-T....home brew or OEM supplied? OEM supplied.

Linear or SMPS used? I have variously used both.  The last was linear, an Astron RS-35A.  But I have also used a Samlex switching mode power supply.

Sanitize your machine now. Scrub it clean and reinstall. If you have not been getting downloads from www.sdr-radio.com you are VERY likely to be infected and have defective or obsolete software as well.

Hi again Joe

I just remembered this. Does not even need midi. USB plug and play!

Anyone have experience of this device with SDRC? I'm quite tempted myself.

Hi Derek

I think "attack" implies some proactive act to compromise one's PC whereas the ads are passive i.e. they are harmless. Yes, annoying maybe, but sadly a necessary evil, like the 4 minutes of ads I am forced to watch every time I go onto streaming TV services like (here in the UK) Channel 4 or Channel 5. Tedious, but the service is free so I put up with it. I can't even "click past" those...... forced to wait (with the sound off!).

I'm far more lenient where anything to do with software that's given free to the user despite thousands and thousands of hours of hard work by the developer (Simon). Hopefully if we like and enjoy it we feel happy to make a donation to the Millie and Beer Fund, or even a few donations. See the top of the Download page!

https://www.sdr-radio.com/download

All the best and enjoy SDRC. It's the best SDR software out there by far!

Great ! Can you share with us what the exact setup for that antenna was?

How far from the house? How high up in the air? On a metal or non-conducting mast? Do you live close to other homes or power lines etc? How long and what kind of coax was feeding the antenna? Laying on the ground or underground? Did you use any CMC on that feedline? If so what was their composition/design? How about grounding of the antenna (length and gauge of ground wire, length of ground rod, type of soil)? Bias-T....home brew or OEM supplied? Linear or SMPS used? heck I don't know.....could go on with another dozen questions but these are the types of things as an RF engineer we need to know to make full use of your observations. Thanks for chipping in.

I have a Wellbrook ALA-330S and the original PA0RDT Mini-Whip from Roelof.

Both perform very well in varying conditions and if I had to do it over again and had limited funds, I would get the Mini-Whip.  I was VERY surprised at how well it works.

I can tell you from exact personal experience that it is a good antenna.


Re: Keeping Tuned Freq in Center

Kriss Kliegle KA1GJU
 

   For a realistic display of **DC Offset, connect to one of my servers that has an SDR-iq… KA1GJU Super Stations #1,2,4 and KA1GJU @ PCARC if you know how to load a server into your definitions.
   Select the max bandwidth, 192 kHz and start it. Takes about 8 seconds, but once started tune to a quiet band where no signals are present and look at the signal in the center. Now re-center display with a right click on either side at a good distance from it and watch what happens. It’s always centered! SDRC will reduce it over time, but it remains. Disconnect from the radio and connect again at the minimum bandwidth choice and repeat. SDRC will do a good job of completely removing it. 

   If I operate the SDR-iq locally, it’s not as pronounced and SDRC removes it completely over time. Not all SDR’s behave this way, but this anomaly is only when I operate via my servers (99% of time), not when using the SDR-iq locally. I have brought this to Simon’s attention over a year ago, but I just live with it and listen to signals on either side on center just fine.


** The DC offset is the difference between the ADC's "middle" voltage and the average voltage present at the ADC's input. The analog circuitry in the SDR will contain biasing circuitry designed to minimize the DC offset.

Interesting Alan. It is just personal preference and in the case of my RSPdx and Console once I hit the center button I do not notice any difference in the detected signals characteristics. Given that if I had a choice I would like to see all my tuned signals in the center.

With many SDRs the local oscillator is at the centre of the display.
Depending on the exact SDR and mode tuning to the centre  may have no effect, a slight effect or even ruin reception/transmission.
That is why it is generally recommended to avoid the centre.

Re: Antennas: Best Mini-Whip ??

Gedas
 

excellent thank you. tests run against other antennas can be most useful & revealing when properly documented & performed. The key is to document exactly what each system was and how it was installed, where, grounded, times of day, freq's, and at least a dozen other factors.

Against a 10 m, L-shaped wire antenna with a wideband 9:1 transformer, and a buried coaxial cable to the shack. From 0 to 2 MHz, the mini whip is far better.
I have just finished building a 1m shielded loop with a differential amp (M0AYF) ; I will perform some test against the mini whip

I think "attacked" is a strong word. Just close down one ad usually, sometimes not even that. Could at worst be described as a minor irritation (IMHO of course).

Re: Reverse Mouse Tuning Wheel

Max
 

Not aware of this as an option in SDRC. It seems mouse wheel can be reversed by editing the registry:

https://www.alphr.com/mouse-is-going-the-wrong-direction-heres-how-to-invert/

What about using a midi controller with SDRC or simply a midi tuning knob? Many on here have done this. Sorry, I don't have the time to search right now but there are many threads on it. Then you can map exactly what you want. I think this might be better for you?

Or use the keyboard arrow keys. This is my preferred method. Just in case you did not know, up/down cursor keys give coarse tuning, left/right is fine tuning, all steps setable for each mode. You need cursor over the spectrum/waterfall display to use this option, or hold down "shift" to activate it if the cursor is not in the display area.

Good luck

Max


Re: Reverse Mouse Tuning Wheel

Simon Brown
 

No,

 

Spin the other way? Mouse wheel down = frequency down, similarly when scrolling a web page. How is this mouse ball thing with web pages?

 

FWIW software only knows that the mouse wheel has spun, not the type of mouse.

Hi,

 

Only from https://www.sdr-radio.com/download .

 

The advertising keeps the software free, without adverts (and donations) SDR Console would not exist.
