Aboutthe radio signals on the island

[Archangel-Player]

I saw this question on Lostoidea and found it intresting.
--------------------------------------------------------------------------
If the Looking Glass blocks all radio communication to/from the island, why does it not affect communication on the island, e.g. between the walkie-talkies or from the radio tower to Sayid's radio?
--------------------------------------------------------------------------
Not to meantion that Daniale's Radio signal was blocking all sigals from being heard but her's. But at differnt points on the island. Sayid and Hurley found that you could hear atleast radio waves of musica. I think it wasn't current waves. But waves from the pastthat where cealed into the island's magnetic field and Sayid's and Hurley's antana was able to pick it up.
--------------------------------------------------------------------------
So question now is. How where the Walkies able to comuncate with each other.

perhaps an error on the writers part? hahaha.

i donno, thats a very interesting point

[bunnydixon]

no idea how it works but could he only be jamming certain frequencies?

if not he does say to and from the island and not within the island.

[Dzbabykel]

Haha I seriously doubt it was an error on the writers part....they seem to know what they're doing ;)

But yah thats a great question and thats the one thing thats confused me?

[navyguy]

This is a very well thought out point. For those that have played Find815 recall when Sam picked up a broadcast of Amelia Earhearts dissapearance as if it were breaking news.

[dudebro28]

i think that this is one of those things that is so small that it wont be taken into account in lost

Actually, I have some real life experience working comm/nav in the Air Force.!. Looking glass prob has set up a ring of jamming equipment that effects in/out traffic. it is also not known what band of frequencies used with the walkie talkies which are usually just line of sight freqs.or UHF with shorter range. With longer distance comm. you would likely use HF or Sat Comm. and therefore would only need to jam those freqs. You can also synchronize your comm equp to encryptically fequency hop at extremely high rates , so only your equp. would be able to communicate.

[Dzbabykel]

Wow....you just spoke way over my head there Robo....care to clarify for us little people?? :p

[Robo42]

I think it would be difficult to clarify, as it took me years of training and exp. to grasp it. I'll just say that systems capable of jamming and encoded radio comm. as on lost were in existance 30 years ago. So it can be done.
Now do i think they need to go into on the show ,no, but the questione was raised and I felt Like I could add something detailed for a change. Not just a wise ass remark.

Yeah, what Robo said. That's where my thinking was but my background is in digital, so I was going to have to do a whole lot of research before I could answer. Thanks for coming to the rescue!

Good points. I am a former Marine and while in Infantry school we were given a class on radios. The instructor told us an anecdote about us still picking up SOS calls from Vietnam as technology catches up. He was only a sergeant so I take it for what its worth, b/c it sounds legendary, but it could be a vehicle for the writers to use to further confuse us.

[Archangel-Player]

I love the military replies. If anyone would know they would. Ok good points. But we are forgetting one thing. What about Rousseau's signal. It was still blocking signals even after the jamming equipment was shut down at the Looking Glass.

Here's some useful information on the types of "Walkies" the Others' used.

It is Motorola CP100 two-way radio. CP100 is a 2W UHF or VHF radio, depending on the actual model. It's speaking distance would be about 3-4 miles in open terrain. However, the obstacles found on the Island(s) (Hydra concrete building, jungle, hills etc.) will decrease the talking distance significantly. However, this factor may change as there might be a repeater the Others use to overcome this problem.

It is not possible to find out the model, therefore it's not known whether it's VHF or UHF

A possability
Here is a list of types of waves.

Band name Abbr ITU band Frequency
and
Wavelength in air Example uses

< 3 Hz
> 100,000 km

Extremely low frequency ELF 1 3–30 Hz
100,000 km – 10,000 km Communication with submarines

Super low frequency SLF 2 30–300 Hz
10,000 km – 1000 km Communication with submarines

Extremely high frequency EHF 11 30–300 GHz
10 mm – 1 mm Radio astronomy, high-speed microwave radio relay

-------------------------------------------------------------------------------------
My guess is thatthey where using


Very high frequency VHF 8 30–300 MHz
10 m – 1 m FM, television broadcasts and line-of-sight ground-to-aircraft and aircraft-to-aircraft communications

Or AKA VHF. Why? Because anything higher than that was cut off such as satlight phones,satlights,Cell phones,Any type of satlight used machine was disabled. anything that used signal towers where disabled. So that knocks out anything with UHF or higher. Because the waves reach a longer space outward.

Where VHF. Use low signals that was why Lenard and his partner where able to hear Daniale's distress call and Lenard was able to hear the numbers he always mumbled. Because they where in a sub which uses low signals.

[bunnydixon]

i'll go with my simple little explanation - my brain can cope with that LOL!

[Robo42]

Arch, I am extremely impressed and is actually a good review for me. Man! did you do some research. So I guess in final analysis we can assume that the tecnology exists at least to make the comminication issues plausible, I hope.
