Didn't Know It Was My Turn To Oversee & Correct Your Responses. "Looks Like Someone Got Up On The Wrong Side Of The Bed. Hope You Have A Better Day Tomorrow."

Not That Is Too Funny.... You Admit Missing Something On A Post - And Now I'm Supposed To Have Picked Up The Slack & Respond To The Post That You & Others Missed. Really......

Sir - That Is Awesome..... My Cudo's For Not Being Partially Illiterate In Today's Society..... You Rock........Good Stuff.......

So..... Is Anyone Going To Answer All Of Bill's (WSJQ725) Legit Questions ? Or Does He Need To Start Another Forum To Get Complete Answers Aside From Quick Shot Answers ? "Hot Dogs.... Armour Hot Dogs.... What Kinda Of Kids Eat Armour Hot Dogs."

Talk Around Is Nothing More Than A Created Motorola Term For Simplex Communications. Nothing More - Nothing Less. No Magic Here......

A Better Term Would Be That Repeater Access Would Not Be Allowed. So In Short - Yes. It Could Disallow Someones Use Of A Repeater.

MDC Is Legal For Use On GMRS. MDC Is A Motorola Brand Name For AFSK - Auto Frequency Shift Keying. See Definition Below: AFSK Encodes Digital Bits Into Two Audio Tones To Be Transmitted On Analog radios. § 95.1777 GMRS tone transmissions. In addition to audible and subaudible tones used for receiver squelch activation and selective calling, to establish or maintain communications with specific stations or to access repeater stations (see § 95.377), GMRS transmitters may also transmit audio tones for station identification (see § 95.1751). § 95.377 Tones and signals. Personal Radio Service stations that transmit voice emissions may also transmit audible or subaudible tones or other signals for the purpose of selective calling and/or receiver squelch activation. These tones and signals are ancillary to voice communications and are considered to be included within the voice emission types, e.g., A3E, F3E, and G3E. (a) Tones that are audible (having a frequency higher than 300 Hertz), must last no longer than 15 seconds at one time. (b) Tones that are subaudible (having a frequency of 300 Hertz or less), may be transmitted continuously during a communication session.

Nope. Nothing Illegal About It For Private Use. Businesses Use It Per Part 90 & It Is Also Legal For GMRS Under Part 95.

DPL (DCS) Coded Squelch Repeaters Are Different On How The System Recognizes The End Of A Received Transmission. No Squelch Burst.

Reverse burst is usually generated on commercial 2-way transmitters to eliminate the squelch tail noise burst in systems using PL, or Private Line. "Reverse burst" is a Motorola term, and GE calls the same thing "STE" for Squelch Tail Elimination. Reverse burst or Squelch Tail Elimination ("STE") is a process that uses a change of the phase of the PL tone encoder for a short period of time after the user unkeys the PTT button. The term "reverse burst" is used to describe the deliberate phase change for a specific abount of time while the transmitter carrier stays on - about 150 to 200ms - with the phase of the PL encoder offset by from 120 to 180 degrees (180, naturally is a complete reversal). During the reverse burst time period the reverse phase stops the PL decode reed dead in its tracks - which slams the receiver squelch closed right now. By the time the transmitter actually drops off the air the RX squelch is already closed - which results in no burst of squelch noise being heard.

Correct. That Sounds Like A Squelch Burst. Most Repeaters Have The Option To Do A Reverse Burst To Eliminate The Static Sound At The End Of A Repeater Received Transmission.

Don't Believe They Are. I Personally Don't Mind If Folks Use Them On My Repeaters, But I Do Not. May Sound Cool Like PD & FD - But To Me It Sounds Like Someone Is Pulling The Gizzard Out Of A Chicken From The Wrong End...... SQUAWK........

No, Not At All. Kenwood Vertex Standard, Icom & Others Recognize This Type Of ID. MDC Is Commonly Referred To As The "Squawk" After A Transmission. There Are Also Other Types Of ID For This Purpose. They're Just Not Called MDC.

MDC = Motorola Data Communications. It Is An ID Assigned, Programmed Into & Associated To A Specific Radio To Allow Transmissions On To A Repeater. It May Be A Pre, Post Or Both On A Transmission For ID So A Controller Can Recognize & Validate The Incoming Signal. Some Use It As A ID Only For Other Radios To Recognize The Individual Ttansmitting.

IMO - Folks Should Do Some Real Research On A Radio, Before Putting Out A Bogus / Nonsense YouTube Vid. This Type Of Junk Does Noting But Confuse New Potential GMRS Users. Some That Just Recently Purchased A Ham License & Now Seem To Be RF Experts, Are Putting Out Vids & Disputing The Manufactures Specifications On Their Products. Really.........
