I heard that there is something in the receivers that can be read from planes in the sky. this person said that he had to take something out of the receiver so that it can not be detected in any form. is there any truth to this. thanx

You're gotta be kidding, it's not a transmitter, what are you thinking ?

[midwest]

sounds like a rumer made up by dave to scare people. A receiver only receives, but i did see dish network going down the street with something electronic like a radar gun he was pointing at peoples dishes from his van. I don't know what he was doing but it was real early in the morning. I watched him for awhile and seen him point at 2 differant hauses and then write something down on a clipboard and then drive on. If anybody knows what he was doing please let us know because this looked very strange to me.

homeland security needs to hire dave and charlie,
if they got that kind of shit they could detect terrist. I heard they also had some new toilet paper that would send a signal out after
you used it if there was anything other that a EXIT ONLY sign on
your ass.... :moon:

[skinerd]

I believe this came from Canada, there was a case there where it was said that the illegal satellite equiupment could disrupt air traffic.....if that was true, there would be planes crashing daily......more BS trying to convince the gov. to crack down.......

If you can't dazzle them with brilliance......
Baffle them with bullsh*t..........

Of course....he's right, you have to take the m/b out of the reciever so they can't detect it.....LMFAO! :moon:

[skinerd]

skinerd,

Please don't be offended, but I always thought it was "if you can't baffle them with brilliance, bombard them with bullshit".

no offence meant ur the man, and u have my utmost respect.

no problem, I suppose it depends on your age and what part of the country you are from as to the saying goes.....but same difference really.......

[coolwind]

Well you can do like we had to on our CB Radio Amps putting off too much RF ! Should work on Recivers the Same way !
Build you a Box Wraped in tin Foil inside & out to cover Reciver So it will Scramble the Signal !
Make sure you put a Small fan in bow to cool reciver

The AVR boards emit a RF signature on 121.5mhz which is the aviation emergency beacon frequency.

I have put a scanner on 121.5 and I can hear the AVR buzzing about 3 houses up the street.

Why does this happen? Simple, all square wave devices emit signals on the odd multiples (harmonics). Take the base frequency of echostar which is 4.5mhz and multiply it by 27 and you get 121.5mhz.

A radio van can easily detect who is running Dishnetwork hacks by driving up the street looking for 121.5 signals. Since that frequency is protected by the Radio Act, they can demand for you to stop otherwise you will be charged under the Radio Act. Myself, I hate to go in front of a judge because my poorly built AVR board was causing Emergency beacon detectors to false.

Those people who run unshielded cables out of their unit to hook it up to their computers are in essence connecting a very nice antenna.

Here's some 9 month old comments from Mili on the subject - I questioned it myself, but this makes sense, and concurs with TDavis80's post.

Actually you are wrong guys. THere is a big fucking radio interference, it is well documented and it is dangerous.
IF YOU ARE USING AN AVR BOARD IN A ECHOSTAR RECEIVER.
The fucking AVR chip resonates on the same frequency as the emergency distress of the aviators. Once of the reasons I will not sell any (besides they are superseeded by AVRs). The AVRs are OK.

Let me correct my previous post, ATMEGAs are OK, AVRs are not.

Mili is totally correct on this one. There are two things you can do to protect your self on this. If you have an avr, quit using it and buy an atmega from mili, or reposition the avr inside the ird where it is shielded by the case of the ird. The level of shielding will depend on the model ird....i can't solder, so forget option 2, lol.

Hell Chief , that's your post count , I thought it was the date/year ... ;) 2003 !

Well, now that I convinced my daughters to move out of town, I DO have a little extra time, Skinerd. Funny....a not-so-famous Hungarian tennis player told me the same thing not long ago :D
Here's another post, so you won't be confused, Cappy. :p

[Chief]

Hell, I guess, BBD....you're witnessing my baffling, not my dazzling :D

[tdavis80]

The reasons why the ATmega cards do not emit RF are simple....

1. The ATmega does not stick out of the reciever as much as the AVR (the AVR problem is lack of shielding)

2. The ATmega is usually not connected to the computer via a cable (the cable becomes an antenna increasing the range of the signal)

3. And the biggest reason... The ATmega does not use the 4.5 mhz clock, it uses its own crystal around 18mhz (various models have different frequencies) which means the harmonic would not be on 121.5.

It is unforunate that some 'senior' members are denying this because it is easily verifiable. Simply turn on a radio scanner and punch in 121.5

Insert the AVR and the scanner goes nuts with loud buzzing noises.
Remove the AVR and the scanner goes quiet.

Go for a walk up the street and see how far it goes.
Now go for a drive around your neighbourhood and see how many of these are being used.

[tdavis80]

PS: As a pilot, I can tell you that all transport-grade aircraft monitor 121.5 at all times. Consider it part of protecting each other since the beacons generally do not go very far and a real air disaster might only beacon for a very short period of time (fire melts the antenna?).

That said, pilots get very concerned when they fly over an area and start picking up signals on the emergency frequency.

Note: A perfectly good beacon transmitter makes a warble sound like a siren. A partially crushed beacon might only send strange buzzing noises.

[leet83]

there is a new technology that allows hard drives to be read from planes....saw it in pop mechanics...maybe yer friend heard that....

[skinerd]

I don't doubt that these do emit a radio frequency.
It is just that what I read said that it was dangerous to air traffic. An annoyance, ok I see that, dangerous, I don't think so.....
