Here is the updated address for the YouTube video now in correct orientation.
https://youtu.be/mrPIcEKPGJY
Told Taka at AOR just now about radio heating up. However, this seems to be a problem that others are not really noticing. He asked me to bring the radio right over, he wants to exchange it for another one, and wants me to continue working with the updated firmware. Well, I'm probably one of the closest in proximity to AOR, so I'll be giving more updates later.
Steve

Thank you for the video .

To my ears the radio sounded good.

I think a firm wear upgrade to improve the display of the main frequency is in order.
The numbers appear to blocky for my liking ,maybe a different font.

I did not see any stations at full signal strength .
What was the antenna in use ?

Would you please make a video in the HF spectrum .

Well we have some good news. I went over to AOR this morning and spent some time talking again with Taka. He took the radio back and gave me an exchange radio. I said, "make sure you give me another power supply just in case that's the problem." So we measured the voltage with an open circuit.
17 volts (seventeen volts). The secondary windings in the power supply were shorted out. So here I have been running the AR-DV1 with a PS putting out 17 volts. I suppose I should have put on a voltmeter on there and checked that myself. But see, I told you I'm a retired physician. What do I know about electronics. Anyway, no wonder the radio and PS were running so hot. Since I left, Taka ran another good PS on the radio I brought back and all was fine. The current drain of the radio was 500 mA at 12 volts. My gosh, no wonder the radio was acting "wierd."
OK, now that we have that little problem solved, I can get down to evaluating the new firmware. Bamascan, I will be curious what your findings are. Now I'm good to go with the radio again for some more testing and more positive. Frankly, I can live with some stuff "not working great" knowing that updates are on the way. I was afraid the radio was a real POS (pardon my language) with the overheating from the get-go. I kept saying to myself, and to some of you, that this CPU just is working too hard, and really thought there was a design flaw in the radio. Anyway, glad that "hot, no scorching" issue is probably over.
Glad the videos are helpful. I was using an external speaker for that video. It was at 4 AM in the morning and I could aim the speaker towards me. The speaker on the radio sits near a wall separating my office from where our bedroom is. Had I awoken my XYL with digital decoding, the radio and PS would be the least of my problems. You guys (gals) would have to find someone else near Torrance.
I'll try and post a couple more videos in next week or so when I get a handle on the new firmware.
By the way, Taka says he is quite impressed with the 536HP. Wants to know if can keep it for a few more weeks. I said sure, I got two more.
Oh, one more positive piece of news. I specifically asked Taka about the software, and whether the code in the radio was similar to past AOR radios, which obviously would make it easier for someone like Gommert at Butel to work with. Taka said it is very similar to the code for the AR-5000. He has been in contact with Gommert. So knowing that software may be a real possibility, I feel better about the radio as well.

Hello,

Having a AR-5000 and looking at the commands (see my earlier post), I would say they are similar. AOR tends to use the same two letter command codes for basic functions.

It will be interesting to see what some of the commands actually do.

The meter doesn't seem to reflect the true strength of some of the signals. Most of those signals on my 996XT and 536HP would be 4-5 bars. But some of the stations I had in there were CHP stations on low VHF about 50 miles away. The antenna was a mini-discone sitting outside on my BBQ. I have a 2/440 antenna at 30 feet and 450 Mhz and 800 Mhz yagis up at 25 feet. Just have not gotten around to using all of them yet with this radio. Now that the radio won't burn up, I'll keep it on a bit longer.
Regarding HF, I think the radio is very good on MW/SW/ham bands. I am a CW guy at heart from my teenage years in the 1960s, and the 200 Hz and 500 Hz filters with CW sound pretty good. AM shortwave stations come in nicely.
This is the only receiver I have ever used where on band A, I can listen to 40 meter CW at night, and on band B, the radio is decoding P25 LAPD and NXDN RR stations here in Los Angeles. Have heard some DMR, but really have not listened much. What I heard sounded good. Maybe this week I'll run one of my D-Star radios at really low power outside, and have a friend come over with a Yaesu FT1DR. We'll put this radio through a digital receive work-out.

I will leave the two letter command codes to guys like you and Gommert. I know very little about that, though I should probably learn. Thanks to folks like you that come up with some neat software.
Regards
Steve

I presume some of you saw my YouTube video of the AR-DV1 here in Los Angeles at
https://youtu.be/2O46DOwuF_g I rotated the video through the YouTube Editor but still cannot get it right. So some of you guys will probably say "Steve doesn't know up from down, left from right" and you're probably right. Now to get serious.
I downloaded the new firmware 1505G about 90 minutes ago and have been using it with the AR-DV1.
I don't really see any improvements in some of this issues I have described. If you look at my YouTube video with the 1505C firmware just before the update, you'll see a scan speed on analog of about 10-12 sec and much lower on digital. When the radio hits a digital signal, it really seems to stall, then picks up speed. However, this is only when I turn the squelch up to more than 80. Anything less, and the scanner stalls in search and scan. The new firmware doesn't do any better, and perhaps a bit worse. I am also not really impressed with the digital decode and voice quality, either analog or digital. Its OK, but only OK. I would expect much more from a receiver in this price range.
I told Taka and Jeff at Ham Station I would keep the radio for one more firmware update, but in the last 90 minutes, I can see there is nothing major that will help me. I hope many of you find this radio to be useful. Perhaps if software becomes available, and if I see a few great future reviews, I might be inclined to actually purchase the AR-DV1. But not at this point.
By the way, during the time I have been writing this post, the radio has gotten hotter, the scan function has stopped working, and the radio is making a loud clicking noise, and there is now no receive function, even on the weather stations. Turning the radio off and on stopped the clicking, and the receive function came back on.

The CPU is probably being overtaxed and when it overheats it will start having issues.

You cannot fix a poor hardware design with firmware. It needs to go back to the drawing board, new complete design new model. This one is a dud.

As mentioned by Steve in post #263 in this thread, the heat problem was caused by a bad power supply. He now has a new radio with a new (and properly working) power supply, so I expect that he'll not see this particular issue again.

Overheat

Steve,
Glad to hear that you are able to get the overheat problem solved, and replaced the AR DV1 and power source. Makes you stop and think, if the next time a scanner or receiver starts acting up check the input voltage. Hope all is good now!

I have used the replacement AR-DV1 (radio) and power supply (PS) for several hours today. The radio is running much cooler, and the PS is not burning my hand. For those of you who don't know the story, read my post #263 above. Now the radio is working somewhat better. This is also with the new firmware 1505G. The radio seems to be running quite well.
For those of you who want an all-mode radio with a lot of digital modes, this radio may be for you. If you have lots of NXDN and DMR in your area, you may want to consider the radio. The MW/HF/VHF/UHF sensitivity is pretty good. The MW/SW broadcast receive quality is pretty good, the WBFM broadcast quality is pretty good, and the analog/digital sound is pretty good. If you don't know yet, I have posted a video on YouTube of this radio scanning through analog/P25/NXDN stations here in Los Angeles.
All the above said, however, this will probably be my last, or one of my last, posts as a beta tester for this radio. This radio is certainly a novel idea, and I applaud AOR as the first one on the block (so to speak) to give all of us an all-mode radio. But a lot of the technology is old. There is no trunking, the memory is arranged in banks, and there are a total of 2000 memories. Twenty years ago, this might really peak my interest.
But I now have scanners with virtually unlimited memory, trunking, and DMR, HP, or object oriented scanning that make "banks" pretty obsolete for me. I prefer the new x36HPs for their features, but whether you like the 96XTs, the 36HPs, or the GRE/Whistler object-oriented memory, it is certainly far advanced from "bank" scanning of the past. And of course, so is the "trunking."
Probably 75% of the scanning that I do involves trunked systems. I probably have at least 5000 channels/TGs programmed into my Uniden 996XT/P2, and more in my 436HP/536HPs. So for me, the "bank" concept is going backwards. No trunking is also going backwards. For MW/SW/HF, I use SDRs like the Perseus and ELAD FDM-S2. And now I play with RTL dongles, FCDP+, AirSpy, and SDRPlay, all with a lot of neat software, not the least, which is DSD+.
Some of you may ask, "Steve, if these things like no trunking and banks were show stoppers for you, why did you even consider buying the AR-DV1?" Good question. Well, I am always good for a new radio, and I said, what the heck, it sounds really interesting. BUT, now that I have been fiddling around with banks and no trunking for the last week or two using the AR-DV1, I realize just how far the new scanners have come in their features. I thought I might be interested, but there is no going back in time.
And once a CW guy like me gets used to 10-20 Hz bandwidth on my Perseus, ELAD, or when operating CW, my FLEX-5000, no wideband receiver will ever come close.
So my final, or one of my final comments, about the AR-DV1 is that it seems to have possibilities, and for some of you looking for a wideband all-mode (including digital modes) receiver, this radio may be worth your consideration. But for my purposes, it is not what I want. For me, fortunately, the $1200 is not so much the issue. The issue is more about "time."
What time I do have for radio, I want to be using the most up-to-date scanners available for scanning, and learning more about the features of SDRs and software like DSD+ 1.7, which I can use together with SDR-Console, and monitor NXDN, DMR, and lots of other stuff from remote receivers across the world. For HF and SW, I have much better radios.
Since I do speak Japanese, and since I have established a personal relationship (not business) with Taka at AOR, I will be glad to help facilitate any issues that you may have with the radio or upcoming firmware. Of course, I will continue to monitor and post on these AR-DV1 related threads, but no longer as a beta-tester or potential buyer of the radio.

Interesting comments.

Thanks for your candor.

SDR really is proving to be a thorn in the side for all of the 'traditional' receiver/scanner manufacturers.

There is no going back though - Once something is invented, it cannot be un-invented.

Not for $1200!!!!

Right on.

This is a really tough market to break into.

Multi-standard DV mode reception is no longer a unique selling point thanks to SDR and open source software decoders.

General hobbyists will likely baulk at the price of the AR-DV1 and instead look at a scanner, RTL or Airspy type device which arguably offers so much more capability at 1/5 - 1/20th the price (in the case of SDR).

Government users will look at the capabilities and specs and likely come to the conclusion that the AOR simply doesn't have the performance or capabilities for their needs.

This device is an oddball that sits in between sectors, but the lack of trunking and other capabilities really rules it out for both hobbyist and Government use IMHO.

I thought this device would sit well on my desk too initially. Now that I have had a chance to think about it, the AR-DV1 simply can't match my Airspy for capability on the V/UHF bands and it can't match my Ham Radios for perfomance on the HF bands.

I can listen to 10 VHF Aviation channels simultaneously within an 8Mhz bandwidth using my Airspy.
I can monitor ADSB and other wideband digital modes, I can scan and search at ridiculous speeds and easily see signals on the waterfall screen at -140dBm or lower anbd decode multiple DV modes at very low signal levels.

To sell, the AR-DV1 needed something new. Some sexy new capability or feature that wasn't available elsewhere, or it had to evrything it did very well. Thus far, I see no evidence of this.

You can't really compare the AR-DV1 to Airspy or SDR dongles since they need a host computer to operate. You can turn the AR-DV1 on from a cold start and be tuning around or scanning (albeit slowly) very quickly. How long does it take your laptop to boot up, then open the program, etc? Plus there is a considerable size difference, power requirements and so on.

The RF performance of the little dongle SRDs is grim compared to a larger hardware based receivers with tuned RF front ends and higher dynamic range components. Plus some people just want a radio with knobs, so SDRs are not for everyone.

I hope AOR gets the ARDV1 dialed in and working to a level that satisfies the average user and if they do it should sell fine at $1200, although less is always better.

I pretty much agree with prcguy. The RF performance of the DVB dongles is (with just 8-bits to play with) pretty poor. I think 8 bits pans out at about 50dB of dynamic range, so the operator is always caught between sensitivity/noise and overload. I found my Newsky stick was OK on a quiet VHF or UHF band, but give it some real HF or MW(AM) action and it was a serious mess. From what I've read on here, the DV1 is miles better than this (and it should be at $1200).
I'm one of those guys who likes to manually tune with a nice knob, this point & click is soul-destroying for me. If AOR can get this radio sorted out, I can see it appealing to those of us who don't mind spending a bit of the kids' inheritance for a nifty new plaything that doesn't need a laptop/drivers/plug-ins and all the rest of it. BTW, just in case anyone thinks I'm just an old stick-in-the-mud grouch, I own a Funcube Pro Plus and and SDRPlay. Both these work fine, but I keep going back to my traditional stuff.

Well I agree with Boatanchor, you can do so much more with SDRs and available software. But I also have to agree with Prcguy and Andy3, there is something about having a real radio that does not require a computer to control.
Earlier tonight, I started playing with SDRPlay and DSD+. By the time I got things set up (only had about 15 minutes to mess around), I said, the heck with it. I just turned on the AR-DV1. There was NXDN and DMR stations right there to listen to.
My wife of 39 years is right. She says I change my mind more than the wind does in Chicago (We met in Chicago). I told her about my frustrations with the radio (she is N6FXG but rarely active). She listened, then said, "tomorrow you will change your mind again." I do have to say that if I bring this radio back, I am going to miss fooling around with it.
As more of you express some interest in this radio, it makes me think what the heck, just keep it and ride with the new firmware and let's just see what happens. By the way, the receiver has been running much better now that the PS problem is fixed. Listened to shortwave and AM broadcast earlier using my indoor AOR LA-400 loop just to see what kind of quality I would get. Actually very strong signals, good sensitivity, and a pleasant experience.
