XTL5000 ADP Not Working

[kd8bmb]

Have an XTL5000 that ADP will not work for some reason.
Flashcode: 500008-000484-6


The radio acts like it has no idea that ADP is activated in it. Updated the firmware to the newest version and that didn't solve the issue. Receives clear channels no issue. When it tries to receive a channel with ADP it knows it is receiving but doesn't decode and pass audio. The encryption symbol does not appear either.

I have never seen this before and I am at a loss. Any help would be greatly appreciated.

Have to ask, you’ve set the proper Key ID and key value?

Are all devices in the encrypted group using the same Key ID and key value? And just a reminder that encryption is illegal on
Amateur Radio, FRS, GMRS, and MURS.

Show me the man and I'll show you the crime.

The above plus you are not trying to load software ADP via KVL are you?

Yes this has been verified

Negative no hardware board in radio strictly ADP in CPS.

Yes they are all using the same key

Going to be ultra super technical with the law here for a moment....it's not actually illegal to use encryption on amateur, so long as you publish the encryption key that is actually in use, and it's freely available. Yeah that's really picking nits. But it's true.

Its not even showing the slashed O ? or any LED indicator? on receive of encrypted transmission? It set to ASTRO receive? thats weird, maybe try reloading the firmware again

What happens if you put in the wrong Key ID/key

If you're not seeing the Ø symbol on the display when you're on that channel, then something isn't setup correctly in the codeplug. Let's assume that you know ADP only works on a P25 channel, so you need to have the personality set for ASTRO TX/RX. Do you have the conventional personality strapped for Secure mode, or do you have it set to Clear or Select? If it's set to Select, do you have a SEC menu item to toggle between modes? Finally, is the channel using the correctly personality? If all of that has already been gone over twice, then something might be wrong with the radio itself.

Encryption is not illegal on MURS. Motorola RMM2050 comes stock with a voice scrambler. However, new devices that feature encryption will not be type certified. So the only legal encryption on MURS is on devices certified before the Part 95 reform. Also, the man asked a question about ADP - not where ADP is allowed

Encryption is not illegal on MURS.

To expand on this, Scrambling is not equal to encryption. Scrambling is an analog privacy system and still uses the allowed emission designator of F3E, in order to use ADP (or any P25 based encryption algorithm), you must use P25 which is not legal on MURS as it is an emission of F1E which is not allowed as a valid emission on MURS. Interestingly enough AM is allowed as is frequency modulated data (as long as the data packets do not contain voice frames).

Designator Common name
A1D Amplitude modulation; on–off keyed or quantized; no modulation; Data, telemetry, telecommand
A2B Amplitude modulation; Digital, with modulation; Telegraphy for machine copy (RTTY, fast Morse)
A2D Amplitude modulation; Digital, with modulation; Data, telemetry, telecommand
A3E Amplitude modulation; Single analog channel; Telephony, voice, sound broadcasting
F2B Angle modulation, straight FM; Digital, with modulation; Telegraphy for machine copy (RTTY, fast Morse)
F1D Angle modulation, straight FM; on–off keyed or quantized; Data, telemetry, telecommand
F2D Angle modulation, straight FM; Digital, with modulation; Data, telemetry, telecommand
F3E Angle modulation, straight FM; Single analog channel; Telephony, voice, sound broadcasting
G3E Angle modulation, phase modulation; Single analog channel; Telephony, voice, sound broadcasting

So frequency inversion (scrambling) would be perfectly legal, any form of digital voice (including DES-XL, DVP etc) would not be as they also utilize F1E emissions.

Now to go find an AM MURS radio lol. CB part 2!

Didn't see mention of the radio being used for amateur radio, FRS GMRS or MURS.
