aor dv1

[Festa62]

Hi All, i have a aor dv1 receiver and a few months ago i updated it to the 2107A firmware, all was well until thursday 09/09/21 when it started to display no res mainboard, after a lot of digging and searching i found out that the above firmware has bugs in it, so i,ve tried to re-write the firmware using the 1907B fw but i cant seem to get the radio to read from the sd card. is there another way i can write the firmware using the mini usb with some sort of software/programme? any help would be gratefully appreciated.

It IS a bug in 2107A, and apparently a 'deadly' one.

However I know how to cure it. Once 'fixed' the 'NO RES' message goes away and you will be able to install FW 1907B. Only takes a couple of minutes.

No other cure exists, so any advice/posts about factory resets etc will not help.

After consulting with Festa62 his DV1 has now been 'fixed'.

Hi, marlbrook, thank you so much, i was thinking it was going to be an expensive door stopper, couldn't believe it worked. Much appreciated Festa62.

Hi, marlbrook, thank you so much, i was thinking it was going to be an expensive door stopper, couldn't believe it worked. Much appreciated Festa62.

as many problems that I thought i had and with talking to aor about it, I'm back on 2107b because they said it had a lot of new fixes. but when i did try 1907B things seem to change. so as a last resort someone remove the sd card, while i was using 2107b. things seem to change on the receive side. so what do you think, i was thinking about getting gssi but i'm not sure if it would work with 1907b installed. AOR said 2107b was the best for it with gssi.. so now i'm confused. can anyone else fill me in?
THANKS FOR EVERYONES HELP.

2107B? The latest FW AOR have posted for download is 2107A.

If you want to pay the high cost, and really think you need GSSI then you have to have 2107A. It will not decode scrambled TETRA, and much of it is.

My advice to all is to stick with 1907B unless and until AOR bring out a new, correctly tested, and 'fixed' firmware. 2107 was released with several flaws, and is likely to cause problems at least some of the time.

As to the SD Card. Even a small read/write error on it, that a P.C. would just ignore, can cause all sorts of different problems on the DV1.

Solution is to put the Card into a P.C. Copy all the files on it somewhere. Reformat the Card, and paste the files back. As long as the Card is not 'failing' that will eliminate any card problems.

well, thanks i know where to go. i just had so much trouble receiving about 150 mhz. thanks for your expertize's.
well it looks like i'll be hanging around here for a while.

back with the same problemo. went back to 1907b and back to the same dead ears i couldn't believe it. took out the sd card not much changed.
i was monitoring at 70foot tower with a triband 2m 440 1.2. also scanner @ 35 ft, and telescoping BNC antenna 18''. not hard a thing heard.
I just don't get it. i guess even aor didn't understand me..

[marlbrook]

You keep mentioning 150 MHz? Do you mean reception stops ABOVE 150, or just around 150?

Did any of the changes you made make the reception better, even for a short time?

What were you receiving well before in the same frequency range?

Using EXACTLY the same wires from the Aerial, including the same patch leads do you have another Receiver you can test against the AR-DV1? I really mean exactly the same wiring right down to the last BNC plug. If not you should suspect the external wiring.. Unless the DV1 goes almost totally dead on the Whip, I mean hardly any 'S' signal and virtually no background noise at all, then one cannot expect to hear much on VHF / UHF with it.

Spray the inside of the DV1's BNC aerial socket with some switch cleaner. I have known two cases where this worked.

hello:
I'm totally confused but I'll do my best to try to explain, i did what aor was suggesting to install the 2107 fw, because i couldn't seem to receive
much of anything. After doing that not much has changed. i did a suggestion from jeff to test the receiver to watch the signal strength with the antenna on, and dialing in the different frequencies up the band, as i touched the antenna going up the bands the signal increased until i got to
VHF and above. The next i was told to do was to take out the sd card which seem to make a little difference. I then had hopes that was it, until
i tried using the outside antennas and comparing them to my 3000a connected both on the same antenna. It didn't have very good results.
DV1 barely heard any signal or audio, The 3000a on the same frequency was full scale. as i used dmr, yeasu, and Dstar same result.
Both receivers were connected the same way with each different antenna. I did notice how warm it got which makes me wonder if something is going on, The only time a could get a signal on the DV1 in either vhf or uhf was using my HT. I wish i would of received an answer from AOR on what the cost would be to send it in. I don't want to open it up to let any others check it out i prefer AOR do it. But if it takes any longer i'll have to
go else were. So this is where I'm at full rest, installed fw 1907b, my software frequencies installed.

thanks again. 73's

How did you try and contact AOR ?

[k8ble]

yes, they answered all my questions fast but not my last ones. on what it would cost to check it out?

Hi Jeff and all. Been spending most of my time monitoring with the Uniden SDS200. Nevertheless, my DV1 is almost always on monitoring at least one or two frequencies. And sometimes I spend an hour or two with it just "tuning around" lately.

My question for you marlbrook, and any one else who wished to chime is, it if anyone has noticed any difference in actual reception between the 2107 firmware and the 1907B, which I am currently using? Simple answers are appreciated.

As an aside, ALL radios are amazing to me, but I am always fascinated with the operation of the DV1. Thanks again everyone. -Mike

if anyone has noticed any difference in actual reception between the 2107 firmware and the 1907B, which I am currently using

Have two DV1's sharing same aerials, one with v.1907B and the other v.2107A in near constant use monitoring LW , MW, HF, VHF and UHF.

From time to time swap firmware in the DV1's (all to do with eSPYonARD testing and upgrades)

No difference in reception, except 1907B rarely if ever crashes. You asked for a simple answer so I will not go into 2107A's odd behaviour.. My advice, stick with 1907B for the time being (and make sure you SAVE copies of its installation file(s) as it is no longer available from AOR sites. Can however be downloaded from the files section of the AR-DV1 Facebook Group.

To those who are convinced they 'have' to use the latest version of firmware as it must always be the best, 'good luck', in this case you will need it.

Hello, I got screwed with the 2107A update and it shows me 'NO RES'.
I read your advice on this version too late.
How can I fix it? I want to go back to the version 1907B.
Thank you.
