Today was the time to upload the new firmware 1.01I and CPS to the D890UV. APRS is functional, just like we know from the D878UV. The evaluation of the GPS chipset used in the D890UV is quite subjective. It seems to me that the manufacturer used the same GPS chipset as in the D878UV series. After a factory reset, the cold GPS start takes up to 4 minutes. When turning the radio station off and on, the GPS start takes less than one minute. This evaluation is subjective because the test was conducted on the first floor, at a window behind the balcony, where there was no direct view of the sky. Nevertheless, it appears very similar to the already used D878UV II+.<\/span><\/p>\n

The automatic volume control of incoming DMR stations is pleasant. No more loudly competing stations whose operators don\u2019t know how to adjust Mic Gain. The volume levels are nicely normalized\u2014a very pleasant change that I was used to with Motorola and its RX Audio Leveling feature. Here, it\u2019s clearly a thumbs up. The reception is overall „smoother“ and more pleasant than that of most Chinese DMR radios.<\/span><\/p>\n

The reception of the aviation band in AM was also surprising. The reproduced modulation is beautifully understandable.<\/span><\/p>\n

More info coming soon.<\/span><\/p>\n
