island wide 3 (lbi)

[svw]

island wide 3 is a repeater the rx 158.730 whats the tx


thanks

Do you mean the input? Why would you need that unless you are thinking about hacking into their system?

Please don't tell me you monitor the input so you know when a car is on your street.

i broke the cardinal rule. "DON'T FEED THE TROLL'S" !. obviously the guy's a fecal stirrer.

 

[eclipse3256]

not a stupid question!!

Many listeners especially Hams use input's or transmit frequencies to monitor communications . Some times if the repeater is scratchy it is alot easier to monitor the party on simplex and or (input) frequency so as far as hacking into a system like posted that was just uncalled for. Just my 2 cents!!

 

[gcr33]

And many times fools put them in a programmable radio and transmit. Thus violating Federal law and giving scanner geeks a worse name. Don't give me the scratchy thing. If you can't hear the repeater you would not hear the car across town.

Don't hack into radio systems period.

Oh, yes, I can be a stirrer but I only need to hit the send key once.

Since you know about radio, simplex means no repeater, not the input to the repeater. Cut the crap.

 

[eclipse3256]

Simplex means line of sight! I'm not gonna argue about this i have more knowledge of radios and how they work then majority of the people on here. I have over 100 radios and being a fellow ham my knowledge of radio is pretty superior to most.

 

[gcr33]

Simplex means line of sight? Maybe instead of buying 100 radios (why?) you should learn about radio. Is it line of sight on HF? No, it's however simplex. Simplex means simply not repeated.
BTW, what other qualifications do you have besides the ability to buy radios? I have a lot less radios but certifications from taking tests to allow me to repair and certify rf equipment. PS Don't hack into radio systems.

eclipse3256 and grc33, you are both correct. A simplex system doesn't use a repeater and it is also line of sight. See the link below and scroll down to Conventional Simplex Radio Systems:

http://www.police-scanner.info/scanning/conventional-radio-systems.htm

It specifically mentions "line of sight".

Now play nice.

DJ,

To clarify, simplex does not mean line-of-sight, nor does the reference you provided say precisely this. Simplex means transmit and receive on the same frequency. On VHF and UHF systems, the physics results in mostly line-of-sight communication. Simplex communication on some other bands commonly is over-the-horizon.

I take issue with police-scanner.info's additional definition of simplex as transmit and receive on different frequencies without a repeater; to me that's semi-duplex, or full-duplex if the transceiver can Tx & Rx simultaneously. My understanding of simplex is closer to the RR Wiki's listing.

Now play nice.

Agree 100% here.

Okay, since it ays "since VHF and UHF signals are generally limited to line of sight", that makes me half wrong and esclipse3256 half right. Regardless of what it is, this is just another thread that evolved into something that had nothing to do with the original post. I'm not a radio tech nor do I have a great wealth of knowledge about radios sytems, and I don't care to. I know enough to get me through and help me to enjoy the hobby, and that's all I need and want to know. I was just trying to add some clarification to the discussion based on what appeared to be a valid source.

 

[gcr33]

Oh and BTW most taxi channels are referred to as half duplex. The reason being that they transmit on one freq. and receive on another without a repeater. The reason is that the other drivers don't hear other drivers. It's been that way for a long time.
This is true in the taxi band on VHF and some UHF.

Valid reason to monitor inputs

I have all Bergen County's inputs programmed into one radio. It's using a very modest antenna, and yes, I use it to know when there local County activity in my immediate area.

Regarding the input, this is pretty easy. Look up the output onthe FCC's web site. Once you know the callsign, search by it and you get all the frequencies assiciated with it. Program them in and identify the input.

There's also one other valid reason for knowing the input. I've heard several cases where a local PD will disable the repeaters output, for psudo security, and monitor their input from HQD's desk.

 

[gcr33]

And how often do you hear the Mixer off message ie: NYC Fire.

Don't hack into radio systems. Don't keep mentioning things you heard on the radio.

We will lose the ability to monitor as more people go with encyption.

 

[nydxa]

Just use common sense

You are paranoid.
Even now it's been decided that streaming communications on line is legal.
I would not publish transcripts, but remember that the media monitors the same frequencies. You read about what they've heard in the newspaper.

 

[gcr33]

I am not paranoid. I am simply telling those that feel a need to hack into and kerchunk public safety radio not to do it.
Who decided? The internet?
