There Is Something Strange In Tthe Neighbourhood

Post  adrian ss on Tue Jan 24, 2017 8:23 am

Went out with the SDC this morning to an out of the way place and after the 23 had been running for approx 10 mins it started producing a musical warbling tone that was only apparent when the coil was swept through an East West line. Quite noisy it was  alien.
I though maybe my new batteries were acting up but no, they were fine and showing full charge.
The tecta did this once before and stopped functioning when the EMI was sounding. I am wondering if I should send it in for a check up?.
I have used other PIs that sound of a bit when sweeping through NS detecting the earths magnetic field but have never noticed it through EW.

Mate it's Canberra ,it' gotta be the strangest place  in Australia.... geek....  Q12 .... Razz .... Q41

Nah but I do hear what you say ,there's 2 comms towers in my area ,that only in summer scratch ,and only on the rare occasions emit that '' musical warbly emi '' not continuous ,but at intervals ,you can time them precisely , irriating to say the least ,then suddenly stop ,all I can think it would be is some sort of comms testing scratch   V19

No towers visible but a very strong signal. n parliament wasn't sitting at that time of day, but then not much of anything ever comes out of there.  Rolling Eyes

Aliens...Now that would be something actually interesting.  Very Happy

Not far from us is a mbl ph tower. It has been built on a pedestrian bridge crossing Isabella Drive near Chisholm. A big mean looking thing it is.
Anyway they are supposed to be at a particular safe hight above the ground and people. This bugger may be the correct hight above the road but it is way too close to people walking over the bridge. I have measured the radiation strength beneath the tower on the walkway and it is nasty.

What has this got to do with my SDC??.... Nothing at all.  Laughing

The only thing i do with my SDC2300 when it won't behave is
Put it on the ground with coil facing straight out.
Auto tune,
If i am not happy.
I do it again, but face it in a slightly different direction, re tune again.
I keep doing that until i feel that my little sdc2300 is happy and i am happy.
It may take up to five goes. Maybe six. Most times only twice Very Happy
Facing it in different directions each time.
Most times when i stand there, and hold it up and turn myself around while holding it, the SDC2300 will let me know where its picking up the most emi or whatever.

If you have warranty on the SDC2300, and you feel its not running right.
Send it in to be looked at.

Two years warranty left Jen. If it does it again I will send it to the doctor for a check up.
