Question for Rodrigo Perez concerning the Community Installer

Keith McGinnis
 

Good Morning Rodrigo,

I have a question regarding the installer. Having issues once the package is installed. When opening up SDR # the program does not open. When I try to run it as an administrator I get the attached regading COM Ports...when I click ok it shuts down. I'm also attaching a crash report. I've had this happen when both installing on the C drive or an external hard drive

It should be noted that I run another version of SDR# from another directory without any problems.

I'm sure it's user error on my part...just not sure where and when.

Thank you

Keith

Hi Martin,

 

that would be indeed very interesting not only for VDSL interference hunting but also for other applications like you mentionend (antenna pattern measurement, general field strength measurements, interference hunting even at higher frequencies …)

 

Kind regard

Betreff: Re: [airspy] Call-out for new plugin ideas - Signal level logging with GPS position to CSV file

 

Hi,

I've been trying to assist the Radio Society of Great Britain (on a voluntary basis) with the measurement and location of unwanted interference to the short wave radio spectrum from Broadband over phone lines using VDSL.

 

VDSL occupies the radio spectrum from a few 10's of KHz up to approximately 18MHz in several distinct bands that are used for upstream and downstream data transfer. Theoretically it shouldn't radiate from the phone lines, but a number of factors make it particularly problematic in the UK, and it is now estimated that at least 50% of all UK radio amateurs are experiencing some form of interference, which is degrading reception by 3dB or more.

 

Other new technologies such as Wind and Solar Farms, DC power grid interconnects and Wireless car charging are also capable of radiating unwanted noise over many Km. So it is vital that some low cost tools are available to the radio community, to be able to quantify and locate interference sources such as these, before they become adopted on a much wider scale without the EMC implications being understood, and if necessary, challenged.

 

The RSGB and other national societies have been using expensive hardware and software to produce heatmap type plots of interference levels on to maps of affected areas.

 

The results of some of these investigations have been summarised and presented at a recent RSGB annual convention.

 

 

As part of this work I have been trying to put together a cost effective 'drive-by' system that could be used by individuals and radio clubs to help identify interference sources and then also be used to provide visual maps that can be used to graphically show the broadband operators where their equipment is radiating from.

 

At the moment I'm using a hybrid system and some free software (rtl-sdr scanner) that is produced by Ear to Ear Oak software.

 

 

The details of my prototype system and some videos of it in action can be found at 

 

 

The main problem at the moment is the software. Which is really not fast enough for the task when driving around.


What I'd really like to be able to do is setup a number of 'memories' containing the frequency, mode and other relevant details and then be able to quickly scan through them and create a log of these details along with the received signal strength, time and GPS lat / long information (from a separate NMEA GPS receiver via serial port or internal to the PC.)

 

This can then be exported to Excel (or other software) and plotted as required.

 

The frequencies would be chosen to correspond to specific VDSL upstream, downstream and transition guardbands. So that a comparison can be made between levels of interference from VDSL and the 'natural' noise floor, and the extent of degradation to S/N ratios determined. These would be similar to those used for the recent RSGB on-line VDSL survey.

 

 

With the advent of SDR's such as the HF+ and Discovery receivers, I think this would be an ideal basis for producing calibrated data that would be sufficiently accurate to be able to present evidence to the regulatory bodies and hopefully convince them that there is a real problem.

 

It would also be useful for other applications such as surveying radio coverage areas, measuring TX antenna patterns, etc.

I would say even manual notchES - perhaps up to 5 or 6 of them.

Prog,

Is there a config line that can limit the number of peaks displayed to some arbitrary number? For example, lets say that I'm interested in only the largest peak in a given spectrum display. Is there a way i could do something like:

<add key="showPeaks" value="(n)" />

Where n=1 through 'someReasonablenumber'

Thanks,
-Chris

Maybe a notch wouldn't be too hard to get if the feature was added by
enabling you to "draw your notch" over the IF area, after going in the
Zoom FFT, clicking Enable IF and Enable Filter?

The IF pane that appears then already does filtering, and it would be
easy to spot the signal you want to notch out there.

IF processor & Tracking Notch Filter already exists and does the job beautifully. I am very happy with it.


Re: Call-out for new plugin ideas

Pete Ferrand
 

One feature I would find useful is a mute on high signal level option, similar to what SDR-Console does. When a local transmitter starts transmitting, SDR# could sense that and mute the audio to simplify t/r switching and eliminate loud noises and feedback. Of course the level and delay, and perhaps the amount of muting, would have to be user configurable.

Thanks.

Thanks, Tag, the OmniRigSync plug-in works perfectly, just what I was looking for. And as you wrote, very simple to set up.
