Re: Optimum tone freq for detecting a weak

Gordon REASON <gordonj.reason@...>
 

Surely , unless you have a glitch in your audible E-thearial ( Joke .... get it ? ) response , or suffer annoying tinnitis , it's the shape of the tone response thay matters .........

A pure sine wave is much easier and gentler , on the earbones , to listen to , than a sharp singing squarewave or similar .  

Not for me !

There is a whole level of nutjob action on Youtube where they publish copies of music with A set to 432 Hz instead of 440 cos it does Healing and is more in tune with the Universe and stuff.  All about harmonics of Schumann resonances.

Good grief.

Except it isn't.  It's all because Verdi didn't like singers being divas about high notes. Allegedly.

There are even apps that will do the 440->432 conversion.

" 432Hz is favoured by many in the healing game,  occasionally there are them that think 528Hz works better".   

Which has got nothing to do with comms intercept work, and seems more about meditation and cult stuff, but I tried listening to those tone frequencies, including buried in noise.  And she's right.  They do sound 'nice'  and quite detectable.  They also happen to be in the ratio 11/9.  So just for the fun of it, there are now eight user-selectable tones in my gizmo, in the ratio 1.2222222   starting 432, 528, 645 etc up to 1760Hz.   Details will be published in due course (writing it up now, hopefully in time for Scatterpoint)




 


 


Re: KST ghost hoards?

Something that I found by accident a few years ago - if you log in with one PC but don't log out properly then a different PC (with the same log in detail) will still not let you log out.
You think that you've done it but your call remains on the list!

Not sure if it happens if both PC's are on the same IP address (ie at home) but happened to me when I was /P and just closed the laptop without logging off. When I went home I was made aware I was still logged in but couldn't correct it till the laptop was used again. Vague feeling I was actually using KST2ME at the time as well just to confuse.....

Re: Programming 13Ghz Signal generator

No experience of that hardware, but I note from the manual the command has to be terminated with a [LF] only, 0x0A
To quote:
" The format is: wfcxxxxxxxxxxxx + 0x0a, a total of 16 bytes; "

Many terminal progs send [CR][LF]   0x0D, 0x0A  or just [CR]  0x0D  
Putty can be set up to do whatever is needed

The manual also shows the commands in lower case (and I hate seeing hex characters in lower case).

Re: KST ghost hoards?

A lot of stations forget that they have KST in a background window, so 'appear' to be logged on even when no where near the PC/radio.
If I am near radios then I am logged on. If doing other things but looking back occassionally then I post ' I am away'. If I have given up for
the day then I log-off.
I could say simple, but probably not to many.
Simple when you use KST a lot, if you do not, why not have a look at the 'HELP' section in MENU.

Some pet hates I often see on KST:
WHAT IS YOUR LOCATOR ?. Have a look at the 'users list', call, locator, name, and possibly equipment appears there.

Not using 'MEEP'. Fine on a slow KST day, but try it during a contest then complain that 'A Station' never answers me.

The sudden influx of stations when there is an activity/contest on. Shame really as they probably have missed some
good conditions during the month they were not active. Who noticed some good 'coastal ducting' earlier this month ?.

Many others but you need to use KST to spot them.

C17A Globemasters reflect well

Neil Smith G4DBN
 

I was checking the path to GB3CSB on 10 GHz and saw a plane on Airscout. Didn't check too closely, but when it was over Barnard Castle, there was a super reflection lasting almost 18 seconds. I checked the plane type and it turned out to be a damn great hulking C17A. I'd elevated the dish 3.5 degrees and that seemed to be the peak, as the plane was at 30000 ft and only 90km from here. I tracked it over a couple of degrees azimuth, but the signal dropped rapidly.

I'm hearing a sniff from GB3PKT and KBQ (at 340km).  CAM is about S2, so not exactly stellar conditions. No sign of anything from EU. GB3OSW is absent, which is unusual as under normal conditions I can see if via troposcatter over the Peak District. Actually, if I screw my eyes up a bit and boost the waterfall contrast to max, there is a faint smear where I'd expect to see OSW.

After the obligatory transmission to Mow Cop WebSDR to listen to myself on 3cm, I'm going back to making stuff until the troposphere bucks its ideas up a bit.

Plain carrier, I prefer 600 Hz, but when I'm looking for really weak signals on a waterfall, slow alternating tones are unambigious.  500/600 Hz at 5 seconds per tone would be good, as it works on a long FFT with very weak troposcatter signals.

A carrier could be a birdie, and weak A1A CW can just be a plain tone chopped up by troposcatter.

Chirps are not quite as good for visible detection in Spectrum Lab, but if they are really tightly times, they might be useful for time-of-flight analysis of reflected signals or off-axis tropo ducting.
