PL and DCS???

Post by jantman »

Hello,

I'm aware that PL is supposed to be the same thing as DCS. I just got a Yaesu radio, and am trying to program it. My Spectra has the Tx tone set to 119N, but the Yaesu only lists DCS tones of (in that area) 114,115,116,122,125

Is there some conversion?

Thanks.

PL = CTCSS

DPL = DCS

I understand that.

How do I set a DCS(DPL) of 119N in a radio that doesn't offer it as a possibility? Do I just go to the next closest tone, or is there a conversion?

There are equivalent codes, some non-inverted codes are the same as others (340 is the same as 023), and each non-inverted has an equivalent inverted code (132N is the same as 317I).

What model spectra is it? As far as I can find 119 isn't a valid code, I can't even find an equivalent code. Also my spectra RSS won't allow me to enter 119.

Are you sure of the "119N"? 119 is not a standard DPL code.

As the previous reply said PL and DPL are not the same.

Actually, 119 can not possibly be a valid DPL because DPL codes are Octal so the the digit "9" can not be valid.

What radios do you own?: Progreso soup can with CRT

What is it?

There is a standard CTCSS tone of 118.8 Hz, which probably
isn't what you're looking for, but it might be; who knows?
[The "N" or "I" on the end of a number usually means it's a
DCS code, either Inverted (I) or Normal (N).]

I know that it's DCS.

I programmed the radio in the Spectra RSS with 119N as the DPL. Do other manufacturer's radios omit certain tones?

There is a standard set of DPL codes for all manufactures. Actual DPL codes are an Octal number so only digits 0-7 are permitted and some codes are not permissible due to some issues with the bit patterns. That is why the codes start with 023 and skip many numbers.

"119N" can not possibly be a valid DPL code.

I knew 119 was no good, the octal thing slipped my mind though..

When you say you programmed the spectra as 119N is it actually entered in that way? I've never seen Moto software where you could enter it as the number with an N or I on the end, Kenwood does it that way though.

Some manufactures leave out some of the codes, one of our local departments uses DPL, and when they started replacing their GE Rangers with Moto radios they wouldn't take the same code, it was left out of the list, so we had to use an equivalent code.

Anyway.. the solution to your problem is simple.. just forget 119 and pick a valid code to use.

Here is a link to more DPL/DCS information than anybody would probably ever really want:
http://www.open.org/~blenderm/dcs.html

See the 7th paragraph and this:
0 octal = 000 binary
1 octal = 001 binary
2 octal = 010 binary
3 octal = 011 binary
4 octal = 100 binary
5 octal = 101 binary
6 octal = 110 binary
7 octal = 111 binary

Because the DCS codes are octal they go like this:
110, 111, 112, 113, 114, 115, 116, 117, 120, 121, 122......

At least you can get all the matching alternate codes from the tables.

I sat down and programmed it from a spreadsheet, spreadsheet said 119N... I guess I have to find my printouts from our MCS2000's and see what they show...

119(16) = 431(8)

Post by Wowbagger »

*IF* the value "119" were in hexadecimal, that would map to the valid DCS octal code of 431.

Now, why anybody would represent a DCS code as hex is beyond me, but I've seen some pretty silly things in my career.
This is my opinion, not Aeroflex's.

I WILL NOT give you proprietary information. I make too much money to jeopardize my job.

I've seen MDC1200 IDs engraved into radio housings in decimal, so who knows.
