I don't know what's been tried already, but on one PC here the Pluto isn't recognised on most ports, but /is/ on a USB 3 extension cable from a USB 3 port on the back of the PC! On another PC it works perfectly on a powered USB 2 hub.

I'm hoping the new Pluto+ may be better....

Building and Testing a Large LIL Low Impedance Loop Final Episode

Paul Cianciolo
 

Hello All,
I got some time to build a 5' x 5' LIL and located it in the backyard.
I works great. No tuning, no external amplifiers, no bias tee, just the loop and the coupler.

This the final episode in the series.

Thank you

Are you using both usb ports on the Pluto? You need to plug in both ports because, quick frankly, the usb connectors on the Pluto are cheap garbage and the main data connector seems to fail at delivering 5 volts to the Pluto, so you need the second usb port connected to make the whole thing work.

At least that is my experience with more than one Pluto.

Re: Loop Experiment "LIL" Low Impedance Loop VS new improved LiLI Shootout

Francesco Di Giovanni
 

Hi Paul, this is what I was looking for for NDBs reception.
Could you please test the "Copper Antenna" with a 4 windings ferrite core.
Do you think a 75 mix core is adequate for the "Lili"?

Re: Loop Experiment "LIL" Low Impedance Loop VS new improved LiLI Shootout

David L. Wilson
 

One thought that occurred to me watching your very interesting video "Looking at battery charger noise with a LISN..." after watching the Lili low impedance loop video is that I would always turn on the device being tested before turning on the spectrum analyzer.   It did not look like you did that to me.  I have found that the initial "turning on" sometimes generates momentary noise that is not normally present and often shows up on "peak hold".

Re: Digital Anyone?

jdow
 

ALE tries to make radio look a lot like a telephone with a network control sort of paradigm. In order to make communications as reliable as possible. So soundings are sent out and other stations listen switching channels fairly rapidly to listen for the soundings. When establishing a link the calling station looks to its log of recent soundings received and selects the strongest one, which is generally no more than an hour old. So there is no hunting around for a workable frequency. Since it is designed for regional communications, 200 miles or so radius, propagation knowledge is usually valid if any stations are heard. So a link can generally be made first try. Once the link is established a short message something like "up 10 kHz USB" is exchanged and they move off frequency to transfer messages. Since the network covers pretty much all of HF a wide band radio with several receivers, such as SDRC manages, each with an ALE sounding demodulator listening can potentially make the communications more reliable.

I realize that's a little tagngled. "http://hflink.com/alehamradio/" has a good description of what is going on. Bonnie has been at this a whole lot. Mostly I am watching it be adapted to amateur radio, particularly with an EMCOM service model in mind. Brian Lloyd, WB5BL, has used this mode with some success both on his around the world flight and EMCOM work in the Caribbean.

Steve N2CKH is the author of PCALE and MARSALE, the more or less canonical ham and MARS oriented implementation. It's useful; but, his implementation is a bit difficult to setup for many people.

Here is the documentation/inline manual:

 

https://hsmodem.dj0abr.de/doku.php?id=de:start

 

HSmodem is supporting also picture transmission, html files, binaries, etc.

Re: Earths Doppler

Tony_AD0VC
 

I woke up this morning and my thoughts wandered to the doppler discussion. I came to the same conclusion as you have described here. There are two uses of the term. An observer "in the wild" with no knowledge of the source, encounters a signal and observes that signal. As the encounter progresses, the observer will always see the departing frequency as lower than the approaching frequency. In that case, all measurements are made relative to the observers reference frame.  But, if we have sufficient knowledge of the source, then we can define the observed frequency relative to the source reference frame (source frequency). In that case the shift is up on the approach and down on the departure. We are describing two different shift quantities but using the term "Doppler shift" for both.

I claim no expertise in the matter and gladly defer to those who do. This is just how I have it sorted.

Tony

Just a comment that people often refer to "doppler" as to how they know a signal is a non-geostationary satellite, i.e., its change in frequency as it passes.  And of course they are indeed referring to the derivative of the frequency but that is what they (essentially most of them) are calling "doppler".  So in reality, "doppler" is used two ways:  (1)  the difference from the transmitted frequency and receive frequency due to relative motion between the transmitter and receiver, and (2)  the changing (derivative) in frequency as a non-geostationary satellite passes over.  In reality, in some (likely most) signal *listening* circles, (2) is the most common use (using more words like "derivative of the frequency" or "changing of frequency" would be too verbose); those people would refer to the difference from the transmitted frequency as the "doppler shift" (and in the Wiki page refered to, they are addressing "doppler shift").  The main point here is that in usagethe word  "doppler" alone is a general (somewhat sloppy) term that can mean different things.  That (unlike doppler shift) is not going to change. :-)
