Anytone 868 and 878 Specs in Manual are misleading - frequency stability is compliant to DMR Standart!

[spa49]

The Tech Specs in the Manuals of both radios state a frequency stability of +/- 2,5 ppm. The ETSI TS 102 361-1 V2.5.1 (2017-10) DMR Specs states on Page 112 ff

The maximum BS (Base Station Repeater) transmit frequency error from the assigned RF carrier centre shall be as defined in table 10.1.
Table 10.1: BS transmit frequency error
Frequency range BS maximum frequency error
50 MHz to 300 MHz ±2 ppm
300 MHz to 600 MHz ±1 ppm
600 MHz to 800 MHz ±0,75 ppm
800 MHz to 1 GHz ±0,3 ppm

The maximum MS (Mobile Station also Handheld) transmit frequency error from the assigned RF carrier centre shall be as defined in table 10.2.
Table 10.2: 
MS transmit frequency error
Frequency range MS maximum frequency error
50 MHz to 600 MHz ±2 ppm
600 MHz to 1 GHz ±1,5 ppm
The method of measurement is defined in ETSI EN 300 113-1 [1] or ETSI EN 300 390-1 [3].
NOTE: In the 600 MHz to 1 GHz range, it is recommended that the MS is frequency locked to the BS to improve system performance

So since the Anytone radios are both UHF and VHF they would have to have a frequency stability of -/+ 2 ppm max.

E D I T: The FCC test report ... https://www.pc5e.nl/downloads/d878uv/manuals/Test-report-4057939.pdf states on page 7 and pages 15 to 27 a frequency error of not greater than 1.100 ppm which is well within the DMR specs. So technically this Issue is not a technical one but just manual/specs matter Well done AnyTone nice technical specs! But please correct the manual
