How to convert NAC to useful numbers for Moto cps?

[V188]

Some of these NAC numbers have me stumped. I've got some Astro simplex channels I'm trying to program into an xts3000. They have odd NAC's. I can't figure out how to convert them to a useful number that I can load into CPS. They are interop fire/EMS channels mostly.

Is there some simple method to convert?

NAC is a three digit Hexidecimal number these are numbers 0-F. What is the problem?

CPS most likely wants the NAC entered in hex.

I'm aware of what NAC is. The problem is Moto CPS only allows numbers to be entered. Alpha characters aren't numbers, example: $ k2 a. I just made that one up. How do I convert it to work with CPS software?

K isn't a valid hex digit.
Can you enter something like 3eb ?
Don't enter the dollar sign.

They have odd NAC's.

What are some of those NACs?

The software for XTS3000 definitely allows hexadecimal (0-9 and A-F) characters. I'm looking at it right now.

NAC for a conventional channel is entered on the Conventional Personality page, "ASTRO" tab. It's called "Network ID". I'm not sure where you are that you're getting an inability to enter hex.

I can enter F7E into Rx (I can put it in Tx too, but the software complains, because F7E is the receive-all code, which shouldn't be transmitted). I can put ABC in there, or 4FD, or 293 (which is what "interop channels" typically use).

Now APX software, on the other hand, allows you to enter either decimal values or hex values for a NAC. But APX will never, ever program an XTS3000.

F7E is the receive-all code. 293 is the default transmit code. Kinda like CSQ on analog systems.

Well I respectfully disagree. If you knew what HEX was you would know 'k' is not a valid HEX character.

Hex(base 16) is made up of the same numbers as base 10(dec), plus the ALPHA characters A, B, C, D, E and F to make up the 'extra' 6 characters in base 16. One valid NAC I KNOW is correct is $4CE, used by the RCMP here in Canada.

The NAC $293(hex)=659(base10) $4CE(hex)=1230(base10) if the NAC has a '$' sing in front of it, it is a hex number.

$ k2a is not valid because the letter k is not a valid symbol used in hex.

In a lot of radio programming software, the NAC will need to be entered as a hex value.


Below is a small chart to explain. The left column are normal base 10(DEC) numbers every one uses, the right side is the same DEC number converted to base 16(HEX)

1=$1
2=$2
9=$9
10=$A
11=$B
12=$C
13=$D
15=$F
16=$10
17=$11
20=$14
30=$1E
100=$64
500=$1F4
1000=$3E8


How to convert from DEC to HEX you ask?

Try entering $4CE (do not include the dollar symbol, it is only there to tell you the value is HEX) and let us know how that works out for you.

Jay, thanks that's what I needed. For some reason when I initially tried to enter other than numbers RSS balked. I just retried it and it works.

Kay, as I said the K was "just made up". I don't need to calculate anything now since I figured out that portion of rss. But you did provide new info for me to study and I appreciate it.

Thanks comm jjunkie.

Glad it all worked out for you.
