Default Should the AOR AR-DV1 be a consideration NOW?

I've read all of the posts and have put my purchase on hold. My quandary at this point in the firmware development is, given the additions and tweaks AOR has provided in regards, have the changes been enough to elevate the radio?
I realize this might be a difficult question to answer, but are those of you who were originally disappointed with your purchase now happy as a result of the firmware updates?

I have never been unhappy with my DV1, AOR are pretty good at sorting firmware problems out in a timely manner. But they are not to good in conveying information to us on any future updates for the radio, this is important seeing the rising popularity of Whistler etc..

Default Just one persons opinion

The only real disappointment when the radio was released were the Search and Scan speeds. Initially AOR tried to say that the radio was not designed to be used as a scanner, so the speeds were acceptable.

Very quickly however they brought out an update which increased those speeds considerably. For me, nothing else could be described as needing to be elevated.

In my opinion the AR-DV1 remains a brilliant bit of kit. Due to its design it relies heavily on its internal firmware. That is mostly good, as it enables them to add new modes and fine tune many things with updates.

On the other hand as the firmware has to be so complicated, there are a few minor anomalies. Many people may never even experience them. The 'curse' is that when complicated firmware is changed it can lead to unwanted side-effects that do not immediately show themselves. That has happened occasionally, but to be fair AOR seem to continue to correct that sort of thing over time.

Other manufacturers are playing 'catch up', mainly I suspect because overall the AR-DV1 remains a threat, and it is.

A lot of the 'questions' about the AR-DV1 often seem not to look at the whole picture.

Is it the best HF receiver available, no. Does it have the best filtering, no (but putting in a lot of filters, which can never be efficient if 'tiny' and they would lead to a big increase in overall size). Is the audio Hi-Fi quality, no, but perfectly adequate for most things.

However for its size, (footprint), price, and both general and special capabilities it remains unique, and will probably do so for some time to come.

I strongly believe that as a wide-band, multi purpose receiver, especially with all the digital modes it can access, it would be my first choice. The firmware does not always behave flawlessly, but it does most of the time.

There were some compromises along the way, to keep it relatively small mainly no doubt, and it is not alone in benefiting from a bigger external speaker, or external filters in specific cases.

In fact, as that makes the radio of a size that takes up little room on a desk at home, or can be used mobile with ease, both with impressive results, I am glad AOR designed it that way.

Even with 'flagship', very expensive large receivers, compare one against another and one will do something a bit better than the other, and vice versa. That's life I guess.

Of course it would be nice if you could borrow an AR-DV1 for a week or two and try it out. Certainly some Retailers will agree to refund the purchase price under those circumstances, as long as the radio and packaging remain 'mint'.

As for all of us, the only other alternative is to wait for the perfect receiver to come out, and that would involve a lot of 'waiting', lol.

Whatever decision you finally make, good luck with it.

Thank you both. I've decided to pull the plug!! Just placed my order with HRO.

I've had mine a couple of weeks and apart from the odd small annoyance it is excellent. Marlbrook's comment re the outboard speaker is interesting. I find an external speaker benefits the set very little, as the audio filtering (especially the low frequency response) is very narrowly filtered, especially in AM mode. In my experience, AOR seem very keen on restricted 'communications quality' audio. I wish they'd just relax it a bit or give us an Audio Setting menu as in the 5000/5001 range.

I run mine into an external speaker, a BHI Digital Signal Processing (DSP) speaker and this does improve communications audio quality no end..

Default Audio Expectations

I use one too, Mike, but really to occasionally clean up signals themselves and external receiving conditions, rather than the radio's audio capabilities.

Audio is certainly one area where very seldom do any critical 'four' pairs of ears agree, which is fine.

I am perfectly happy if a communication receiver produces voice/music audio that I can understand, and the AR-DV1 does just that.

I realise, especially for music, there are many who have very different taste re treble and base responses etc, but that is not what the AR-DV1 is about. There may be some who even would like to adjust those properties even for a common or garden Amateur FM QSO.

In my experiments I tried playing the radio's output via the P.C., and applying software audio filters. There were differences, but for my, admittedly very 'not bothered' ears, nothing that inspired me to follow that line permanently, with voice or music.

It is not a good idea to buy an AR-DV1 in order to mainly listen to music, which can be adjusted to exactly appeal to individual HiFi tastes. For that one no doubt needs specialist equipment.

The AR-DV1 is an 'all-rounder', and albeit very clever, a Communications Receiver'.

Just to clarify, Marlbrook. I don't use the DV1 for music listening. What I'm talking about is the HPF in the audio path, which seems (to my ears) to roll off quite high. This makes the balance sound 'thin', especially in AM mode.
The 5000 series had selectable audio filters - the HPF had settings of OFF/300/600 Hz and the LPF had OFF/6000/3000. With the HPF set to 300 Hz, the audio sounded considerably beefier than the DV1, and connecting an external speaker really made a difference. Sadly I notice very little difference when I put an outboard speaker on the DV1, which makes me think that the roll-off is set too high.
It's no great shakes, but a fatter sound would be nice.

I understand. I was not referring specifically to your posts. There have been others about music audio on the AR-DV1, not here.

It might be an idea if you contacted AOR putting forward that idea. It may be possible in Firmware.

Although if they do it will mean more work for me, updating eSPYonARD, lol, but I would be happy to do it.

In the meantime, as I said, there are audio tailoring programs available you could try, by sending the Audio output via the P.C., processing them and listening on the Computer speakers.

Cheers

I made a small plastic baffle which I place over the speaker opening on the DV1 and which directs the sound at about a 45 degree angle out toward the front of the receiver, where I am generally seated. This seems to help quite a bit.

Default AR-DV1 audio

Andy;

I am glad to see someone else wish that the audio had more low end than it does. I complained about it here, but only got "it's a communications receiver, not a Bose Wave Radio...." answers. I emailed AOR about it, but nothing ever happened. I ended up selling my DV1, because it's supposed to be an all-around receiver, but I just couldn't take the AM audio.

It wouldn't be hard for AOR to fix this. It sounds pretty good on WFM with its internal speaker, so the potential is there.

I posted this same objection to CommRadio when the CR1 was in early days, and they listened. After some firmware updates, the audio was very pleasant.

So I sold my DV1. I have other AOR radios (5000,5001d,7000) and they all have great audio quality.

The Icom R8600 has been "on the horizon" for about 8 months now, and details about he unit are still sorely lacking. Even if the radio were to be made available tomorrow, most except the bravest and hardiest souls would wait an additional 6 months for any bugs or anomalies to be worked out.

The same holds true for AOR. And successor to the DV1 would have most folks waiting for would require an additional break-in period for folks who have reservations about jumping right in.

So there is not really much cholce. If you are looking for a decent, overall communications receiver, the DV1 is the only radio out there that fits the bill, especially with its wide array of digital reception modes.

Another option would be an SDR, computer based receiver, but my own preference is to be able to sit in front of a radio and push buttons and twirls knobs. I have had my DV1 for well over a year, and have not been disappointed.

Good luck in your endeavors and happy listening.
