NON-STANDARD DPL TONES

[nokones]

I am seeing non-standard DPL tones being used such as D013N these days. As everyone is aware, D023N is the lowest in the Motorola DPL table in the CPS for every model series before the APX series.

Does anyone know of a procedure to manually enter a non-standard tone and will the radio firmware accept the change especially for the XTL and XTS series?

This must be a CCR thing.

Someone local to me is using that code ( 013 ) for a local GMRS repeater. Sucks since none of my Motorola radios have that code and it’s a really nice repeater with great range. I emailed the owner of the repeater that issue and he said he might change the code in the future. But for now - anyone with a Motorola radio that needs 013 for a repeater - not gonna happen ( at least not that I know of. If there is someone definitely tell me )

023 has been the default lowest tone since MSI implimented it. I have various LMR units that all show 023 as lowest. I doubt any of them will change code to allow this odd CCR stuff.

There isn't one.

The big three and the CCR companies include complentary codes for some reason. Motorola doesn't.

There is a complementary code to 013. If you use 013, it will false a different DPL code. I'm not smart enough to figure out what the complemtary code is with out doing some research first. I'm sure there is someone here that can tell you what the complemtary code is.

The 'standard codes don't have this problem and shouldn't false decode.

Some Kenwoods will allow non standard DPL tones, I tried 013 and the service monitor decoded it as 013 so there may not be a "complementary" code. That said, one should not use bogus DPLs.

These document how the inverted codes work and why some codes are not used.

Maybe that’s why the repeater owner is using that code.

its the WOUXUN DPL as far as I am aware... motos will not do the XXXN or XXXI

Yes, I have 2 Older kenwood's that will do non-standard pl's and Dpl's . There are times where I can see this as being useful, even tho not the norm.

I just learned that my Kenwood TK880-1 will allow the non-standard DPL code. You click on the respective tone column and enter "D013" and tab off and it will populate the change. Then I wrote the change to the radio and tried and see if I could hit the repeater, surprisingly it worked.

I wish my Motorola radios would do that as easily that the Kenwood did.

Use of the non-Motorola-standard DCS codes pre-dates CCRs by decades, just like the non-EIA-standard CTCSS tones. Does it just not accept codes below 023, or not accept anything that isn't in the ~83 Motorola-standard DPL codes?

These should all be equivalent codes ("+" is normal, "-" is inverted):
+013 +063 +700 -376 -617 -763

Those pages on the onfreq site are a good resource.

The CPS uses two pulldown lists of CTCSS & DPLs for each the encode and decode to select the appropriate tones/codes. The pulldown lists will not allow any manual entry unless there is a special keyboard procedure to bypass that lockout feature such as control, alt, or shift function.

If there is an equivalent inverted DPL code for the normal D013, I sure would like to know what that inverted code is. I tried each DPL normal and inverted that is on the DPL pulldown lists and the repeater did not accept any of the Motorola DPL codes.

Ima guess the repeater you are accessing is using is DXXXI or DXXXN? yea moto wont do those...

Those codes are all equivalent to each other, at least theoretically ("+" is normal, "-" is inverted):

+013 +063 +700 -376 -617 -763

but none of them should be found in the Motorola-standard list of 83 codes (165* if you include the inverted codes), unfortunately.

*ObFunFacts: +172/-036 is standard but +036/-172 is not standard for some reason, though it is included anyway by some. Also, the non-standard codeset +112/+250/+505/+512 is the only codeset with no equivalent inverted codes.

I can't get my CPS on the XTS5000 to do the D013.

However, my XPR3500e and R7 using CPS 2.0 has no problem with just typing it in.

I may be misremembering but I believe the "Mission Critical" Motorola subscribers will only do the PL/DPL's which they tested years ago to ensure no false decodes due to harmonics for PL or whatever would cause DPL to false.

I discovered that my Kenwood TK880-1 can be manually overwritten.

DCS code 013 in binary is 00000110011100000001011. Long periods of all zeros or ones can cause the timing in the receiving radio to slip, the standardized codes were selected to have sufficient transitions to maintain clock recovery & keep decode sensitivity equivalent to CTCSS.

I know this is an older post, but I wanted to say THANK YOU. This worked for both non-standard DPL values as well as non-standard CTCSS values. I had a local repeater that was using 183.5Hz, which was not an option in the KPG-49D software (Ver: 4.02) but I could easily type that value in and press <TAB> and the TK-880 took the programing no problem and I was able to access the repeater.

It seems so obvious, but I would have never tried to simply "type" a value into a field that has a drop-down menu... Haha.

Thanks again!

Some Baofeng radios are the opposite. The software only has the standard CTCSS tones as does changing the tones with the radio keypad up/down keys but you can manually enter any frequency from 60.0 to 259.9 Hz with the number keys.
