Also, in what compass direction is the TV facing?

I got a Bondstec Microwave Oven BT - 612MW. I think it is one of the first
microwaves, and nobody in The Netherlands has ever heard of this trade mark.
I have been looking for manuals but no success so far. Could anyone
enlighten me on what Bondstec IS, actually (I only found references to video
equipment and remote controls and that stuff, but no proof whatsoever they
ever manufactured microwaves. But they did! I have one!)
I would be interested in finding a manual? From which country is Bondstec
anyway?

Thanks in advance for your help!

Well,how nice this is, I have one also without a manual, so cannot help you there. I have a BT-501 MW. Does this mean he is even older? Someone gave it to me somewhere between 1990 and 1995(used)and it is stll going strong.

This uses a TDA 9103 for H/V controller. Not sure if handles the bow

All other functions are OK.  (Pin,

Can anyone shed some light on this BOW circuit?

 

Anyone have a schematic on this unit OR a scrap mainboard to swap
out?

Maybe not extreme, but it was clever, very clever...

I've rebuilt PCBs using epoxy to make flat surfaces and then used old
PCB repair trace kit to make replacement traces. Making a small PCB from
some good photos is certainly a good idea!

Extreme might be if you had to do this on the ISS (International Space
Station) for the life support logic PCB.

True, but we were talking about extreme PCB repair. Loved the movie, and
remember the incident (I'm a wee bit north of 60 you might say).

Let's review the numbers.

a. They fly a Cessna equipped with a Boeing DRT (dirtbag) overhead
b. It picks up tens of thousands of cell signals during the flight
c. You think they're gonna connect tens of thousands of phone calls?

Sure, we can buy a phone & SIM card for cash, with a
pre-paid cash account, so, now we have a phone that isn't
traced to us (except for the store cameras). We can turn
it off miles before we get home, so, all the bad guys
know is the location where you've used it.

But, after the very first phone call, the phone can now
be traced back to us, because, the bad guys know whom you
called. After two, three, four calls, they pretty much have
you, because they can just *ask* those people you called who
you were.

So, I don't see, realistically, how you can possibly not be
traced, unless you only use the phone once.

I have been checking WiGLE lately, and it knows a string of numbers
about the tower, and it puts the tower on a Google map almost exactly.
T-Mobile 209159_256_17859-GSM-EDGE -85dB 3:33:19pm
T-Mobile 209159_255_10503-GSM-EDGE -85dB 10:12:32pm

When I touch the tower on the map display, it gives me:
T-Mobile 209159_255_10503 - null - HSPA;us
Signal = -79dB
Type = GSM
First Seen = 3:41:11pm

Observations = 94

Any idea what the "observations" indicate?

Googling, I found a few programs aimed at cell towers.

It looks like "open signal" is the recommended cellphone tower tracking app:

http://androidforums.com/samsung-galaxy-s3/679917-cell-phone-tower-locator-app.html

So, I'll test these out, but this search shows that "open signal" is
the one to use first and foremost.

Not if you aren't actually stupid enough to

I tried using that Wigle website, but the filters don't work.
You see all those wifi SSIDs.

Hi miso,
You are mostly correct, in that Android WiGLE freeware appears
to mostly be for wardriving WiFI SSIDs, but, it also lists the
cellular towers it sees.

The advantage is that the cellular tower information nearly
exactly matches the http://opencellid.org maps you pointed us to,
so, you can tell if the tower your phone is connected to is
at least a known tower (and not one of the unnamed rogue towers).

The disadvantage of WiGLE is, as you said, that it clutters up
the output with WiFi SSIDs (which is its primary purpose), so,
we need *better* software specifically for cell tower connection
information.

It seems, to me, that it "should" be *easy* to be warned when our
cellphones connect to a rogue tower, either from the overhead
Boeing DRT (aka dirtbag), or the mobile Harris Stingray, or the
pedestrian Harris Gossamer devices.
a. The rogue cell sites all appear to be unnamed (to date),
b. While they "can" connect the call, they generally disconnect you,
c. They appear to drop your connection down from 4G to 3G to 2G,
d. They all seem to try to put your phone in maximum output mode,
e. They tell your phone they have higher signal strength than they
actually do,
f. If it's on an airplane, then it will exist for short periods only,
g. The rogue sites are not on the existing FCC databases,
etc.

Given that these general characteristics seem to be consistent,
how hard do you think it would be for someone to code up an app
which automatically WARNS the user (sort of like how AV programs
use heuristics to warn users) that a rogue site is suspected nearby?

What would be useful is, when they fly these airplanes overhead,
that the tens of thousands of people being spied upon by these
bad guys all get a notification on their phone of the illegal
activity by law enforcement overhead.

Each flight would make the news.

Doesn’t have to be single use, just used for

By definition you never had any privacy with phone calls.
