AR-DV10 Model march 2023

[hamradionl]

In 2015 got the early DV1 without tetra. Just received the DV10 2023 model FW 2205A to evaluate. Let it run for 10 hours monitor on busy high traffic tetra network.

Day 2
tested tetra using a regulated attenuator, turn down antenna input level to find out when decoding stop. Able to turn down just above first line on S meter and still decoding and will let DV10 run till midnight.
(not using GSSI trunk display foil still on, picture not sharp).

Day 2 full day running not notice any drift.
Digital mode yaesu
working using AUTO and use programmed mode the decoding is 100% also when regulated attenuator tune down to first line on S meter.

The real test for drift is HF SSB and/or CW, find and tune to a stable beacon signal, if all is well the audio tone should remain the same over a long period of time. Testing frequency drift using digital signals (DMR etc) is all well and good but a drifting receiver can still keep a digital signal within the passband without you noticing the drift..

iam not as long in this radio stuff i did not know how to, thank you for advice.

Day 3
setup freq run for whole day on NXDN48 repeater decode fine

All these test are done using DSD+ and TTT as second control receiver.

You can certainly talk the talk, I am surprised you cannot walk the walk

I tried this with my AR-DV10 last year when I received it and didn't notice any drift.

Since then bought the AOR GP5001 - GPS ANTENNA RECEIVER for my AR5700D so it should be rock steady re frequency.

Gonna do the test again with the above two receivers and compare.

Meanwhile, the AR-DV10's P25 decoding, AT BEST, is mediocre. I don't know what AOR were thinking...

Cannot comment on P25 as we have very little in the UK..

I need to make some recordings, comparing P25 decoding with my IC-R30/Uniden scanners and my AR-DV10 and link them here.

When the AR-DV10 actually decodes P25 transmissions, the audio sounds like there's a bunch of Daleks talking...

The most recent production release of the DV10 (March 2023) appear to be in the AA634XXX range with 2205A Firmware..
The previous 2022 release have all been reported in the serial number ranges: AA6336XX AA6337XX AA6338XX and AA6339XX..

My AR-DV10's serial number = AA633697

I take it purchased last year ?

Yep...

It arrived from Japan with 2205A Firmware.

Cant test P25 because there none P25 in about 100 / 150km receiving range.
Only 75+ Tetra channels and 4 NXDN and some DMR and ham DIGI modes.

After 3 full days 24/7 running the DV10, still work and decode fine and in night time i turn down volume but keep radio on whole time 24/7

 

[hamradionl]

day 4
SDR# backup receiver
while TTT + Tetra Decoder are missing some voice, DV10 decode crisp and clear.

Hi to all,
After 5 full days 24/7 DV10 still running on my favourite tetra network (no use GSSI fallow)
Its getting some warm.

Next test be signal behaver.
On UHF i need use a bandpass filter to filter out very strong DAB (220 MHz) and DVBT (500-600MHz) and LTE (800 - 1900 MHz) signals.
Also for TXR-1 and DV10 and RTLSDR while Airspy 2+ airspy mini seem work better as TRX-1 and DV10.
For UHF airband use a bandpass 200 - 400 MHz for tetra use bandpass 400 - 450 MHz

I not buy DV10 for HF because on HF are not DMR, NXDN, Tetra nor Dstar digi mode.

It still drifts. A complete waste of money and a poor piece of junk from AOR (Authority On Rubbish).
