Re: (Farhan) Upgrade parts arrived

Mitch Johnson
 

I've just joined the group, I'm also interested in getting the parts needed to upgrade my FDIM analyzer.  How does someone get the upgraded parts? I did print off the instructions for the modifications to the FDIM Antuino.

Thanks,

Re: Antuino Manual

SUCCESS  I had to take solder sucker and remove all the solder from the pins on the DPDT slider switch and the ext DC power connector; then cleaned & re-dressed the eyelets and mounted switch and DC power connector back on the board less all the extra solder. EUREKA it now works FB producing bright display just using the six "AA" batteries. So now at least I should be able to calibrate it when coax adapters arrive.

Hopefully HFignals will get the mod parts for antuino and my TFT/nano display daughter board for the rig to me soon so I can begin to operate with this.

There have been reports of bad connections for the battery box.  Check the solder joints.

Also the current from a USB port may not be enough to power the Antuino.  Try using a power supply thats 9-12V when using the 2.1mm barrel jack.

If neither of those options work you may have a bad unit.

If you have a dual band 2M/440 handitalkie and can get something like a CF-416 Duplexer and combine that with an Ioio dual band home brew yagi antenna usually used for satellite work that should get you going. connect the antuino in between the HT and the duplexer and you should be able to use the antuino for displayed visual signal indications of the noise and the HT should give you aural indications; although using an HT is just FM usually so maybe an old refurbished radio shack handheld scanner might be better so you can select NFM, FM, AM , AMN or SSB modes to suit the noise you are working with.

Re: Can't upload sketch to Antuino

Arne Nilsson
 

Perhaps this info will help?

Installing the CH340 driver

The Raduino (like most Arduino clones) uses a non-standard driver.  This is because the standard arduino driver chip requires a licence that makes the product expensive.   Arduino clones typically use a CH340 USB To UART part that requires installation of a driver.

Download the latest CH340 driver from the internet here.   There are drivers available for all the major platforms (Windows, MacOS and Linux).

Re: Antuino use to place an FM - DAB roof antenna? - Gerber file available?

Geert.VandeWiele@...
 

Thank you Dave G0WBX,

I already tried out SDR-radio which looks fabulous, but also a bit overwhelming for the uninitiated...
I will have a look at SDR Sharp.
I had the luck to find a dongle saying "DVB-T+DAB+FM+SDR" in my cupboard. With the right amount of fiddling, it seems to work in SDR-Radio. I'll give it a go in SDR Sharp too.
Now i just need to figure out how these SDR programs work. It took me half an hour to figure out how to get music instead of noise when tuning in to my favourite radio station  ;-)

kind regards
Geert  (with two "e" s btw...  ;-) )

Re: Antuino use to place an FM - DAB roof antenna? - Gerber file available?

Dave_G0WBX
 

Hi Gert.

If your using Windows, then SDR# (sdr sharp) is about the easiest to use.

On Linux, probably GQRX, but go to the website and follow the detailed
instructions to install that, so not follow the Youtube versions, most
are so out of date, it's a joke.

Then with either, use the SDR dongle of your choice.  The NewElec brand
are as good as any for simple tasks, as are many others.   Some even
come with simple Windows software too.

Ask around for other opinions too, as there are "Lots" of variations and
options.

Thanks a lot for your input, Dave.
I'm not so familiar with SDR. Googling of course will turn up a lot of DVB-T/DAB/FM dongles and SDR software. Is there any that you prefer personally?

kind regards

Geert

Re: Antuino use to place an FM - DAB roof antenna? - Gerber file available?

Dave_G0WBX
 

Hi.

It might work with FM signals, but I doubt DAB, unless exceedingly strong.

The "RX" in the Antuino is quite narrow band, so you'd need to "tune"
into a relatively constant narrow band signal to get a sensible reading
you could use to position an antenna.   DAB signals in particular are
very wide band, and more noise like in nature than carriers.

It is a good tool for sniffing local RF leakage, from bad/damaged cables
and connectors for example, where the frequency is known.

For your antenna needs, try a common DTV/DAB "Dongle" and any of the
popular PC based SDR programs that show a spectrum plot, of course, not
easy to cart up to the roof, unless you can VNC from a phone to see the
PC's screen.

73.

Dave G0WBX.
