Has anyone tried the AR DV1 on analog channels ?
How is the reception ?
Thanks.

The AOR AR5000 is the most sensitive receiver I have ever owned. As I am a hobbyist that is seemingly constantly rotating equipment in and out of my radio room I no longer own one. I've never found anything better for digging out weak signals. That said is anyone here capable of doing a side-by-side between the 5000 and the new receiver to compare sensitivity, selectivity, etc?
I believe there is certainly room in the world for both SDR's and hardware receivers. I like both. I have a RFSpace NetSDR with VHF/UHF Downconverter on the way to me now. I expect its performance will be superb as all RFSpace products are. However, I like to be able to tune with a VFO as well, and I would consider this radio completely aside from its digital capability were it on a par or even pretty close to the reception capabilities of the 5000.
I think the development of the way this receiver works will come in time. I also must note that it is a receiver and not a scanner, so I don't expect it to work out of the box for any trunking capability, fast scanning, dynamic memory, etc. The fact that it has the digital capability out of the box that it does though is intriguing, but it seems the analog performance over a wide range of VHF and above frequencies has not been discussed a great deal.
Has anyone used the aux output as a discriminator tap? I think I read somewhere in this thread or elsewhere that it worked in that manner. I find it quite disappointing that the receiver, with all of its features, has no capability on board to decode CTCSS and DCS tones, which when DX'ing are key to station identification more often than not.

are you referring to the 5000 "aux output as a discriminator tap"?

Negative, the Aux output on the back of the DV1, which has been since confirmed off-list to indeed be a discriminator output.
ok, got it.
Steve (sshermanmd): It was nice talking to you the other day, I am happy that we were able to figure out the power supply/hot radio issue!
I am anxiously waiting to get my hands on the DV1 myself. Like Scott, I also tend to rotate radios around a lot and will give the DV1 a good shot to make a permanent home on my radio rack.
With the upgrade capability of this radio I suspect that more features will be added as time goes by, I just hope they address them in a timely fashion. It appears that they are so far.
Scott: Have you connected a CD-1 to the Auxillary Output, and does it decode PL/DPL/DTMF properly?

Hi Rich,
I don't have one at the moment, but it was confirmed to me that the aux output does in fact support discriminator audio. If I do get one it'll be a CD-1 attached.
I still can't get my mind around the lack of trunking and signalling.
What is gained by the purist attitude? Trunking and signalling don't hinder RF performance. The government products market excuse doesn't hold water either. Just how many government agencies need receivers? Not more than a hand full I would think. If they do wouldn't they be clamoring for DMR, and all the other "consumer" formats out there? Who exactly are they listening to, the police, EMTs, fire on P25? It just doesn't make sense. I mean really...all that radio just to be foiled by a $200 CS700?

I am buying the AR-DV1. Of course, I've had it for a few weeks, but finally decided to purchase it.
What changed my mind is getting the concept of the AR-DV1 as a scanner out of my mind, and realizing what it is, a wideband receiver. And as a wideband receiver, it is really quite good.
What convinced me in the last couple of days was using this receiver with my AOR LA-400 loop all throughout the house and in my wife's medical office. The sensitivity of the receiver on MW/SW/HF is pretty amazing. Most powerhouse SW broadcast like WWV, Radio Havana, Radio Japan, Radio Australia, Radio New Zealand, etc were S9+ with just the loop on my kitchen table. The audio was great.
Switch the frequency to 3.9 Mhz, listen to SSB hams pretty strong just using the loop. Same for 40 meter CW. Then go to VHF/UHF and pretty good reception. Analog quality is very good. Nothing like listening to 80 meter SSB on VFO A, then switch to VFO B, and listen to NXDN and DMR stations.
Radio still needs firmware updates for issues that I have mentioned. But after playing with it for the last couple of days, I said, this is worth keeping. Spoke with Taka a couple of times in last 2 days. We probably won't see trunking on this radio, and right now, you can only scan one bank of channels at a time. However, this will be fixed in future firmware updates.
I have to get out of the mode of comparing the AR-DV1 to my scanners. It is never going to have the scanning ability of a high-end Uniden or GRE/Whister. But as a wideband radio, this AR-DV1 is pretty good. Much more portable than my IC R8500, but my R8500 does not have digital modes. I have used the PCR-2500, AR-8600 Mk II, and ICOM R-20 as wideband receivers in the past, and the AR-DV1, IMHO, is probably a step up. Plus you have all the digital modes.
One problem is that the AR-DV1 is really prone to overloading. If I put my outside HF antennas on this thing, it will overload like crazy. But that is easily resolved with MFJ-956 antenna tuner as a preselector. The radio could probably stand to use some more preselection, but it is what it is, a wideband receiver. And as a wideband receiver, it is pretty good, plus all the digital modes.

This receiver is way too small to be a boat anchor....and also way too young. In the words of the immortal Shemp Howard of Three Stooges fame, "Rome wasn't built in a day...and neither was Syracuse!"
If you are looking for a scanner, then $1200 is FAR FAR too much to pay for one. If you are looking for a receiver that may turn out to be a winner, maybe not so much.
Only time will tell. AOR swings and misses sometimes, and homers others. Inconclusive if this is a no-hitter just yet. IMHO, of course.

Boat Anchor ?? Ha Ha. It all depends on where you live. I my area DMR and Nexedge and D-Star and C4FM is everywhere and new repeaters are being added weekly. Money well spent. The upgrade the AOR did solved many issues they were having, I would still like to see the digital frequencies scan faster but can live with it. No Trunking ?? No problem. Just add the voice signals and you have a trunked system your scanning. I scan two digital trunked systems daily and don't have a problem.

Looks like AOR will need to issue another owners book with all of the changes they are making. Still waiting on some programing software as well.
Hello
I figured out most of the remote commands today as I was playing.
Receiver will return current value if the command is sent followed by a <cr>. Write only commands do not return a value. Read only commands will only return values.
Response codes: 10=Power Up or Down, 20=Okay, 30=Empty Location, 40=Missing Parameter, 50=Value error, 60=Command Error

Hello,
My observations about my AOR AR-DV1 with updated 1506C firmware.
The receiver is longer, wider, and slightly taller than my AR-8600, although not much bigger. It shipped with 1505c firmware and was upgraded by me. The receiver operation is similar to the AR-8600. It is neat to just tune around and have the receiver decode audio from P25, DMR and NXDN.
All the features are not implemented yet. I was looking at the firmware updates descriptions and missed some features implemented in the initial release, like Voice Squelch.
CTCSS and DCS functions are split like some GRE scanners, so a tone search on a frequency may require two searches. Tone searching is fast.
CTCSS Squelch and DCS Squelch works in FM Mode, but not Auto Mode.
D* works and the receiver displays From, To, and the two repeater callsigns when the Dig.Decode option is turned on.
The receiver will mute and indicate P25 when tuned to a P25 control channel. Some of my other AOR receivers will only decode P25 voice and will not mute on data, voice headers, and terminators.
The receiver can record and playback audio files. WAV files have a 19200 sample rate. No recieve info recorded with file, just audio. I though that the SQL.SKIP did not work as I recorded several minutes with one brief transmission and got a large WAV file. The large WAV file could be played on the receiver, but could not be opened in windows. Other recordings seemed okay.
The receiver can decode DN mode of Yaesu System Fusion. It can not decode VW mode.
Level Squelch does not work in FM. Noise Squelch seems to work in AM mode. The Squelch control and remote commands (NQ, LQ) set both Noise Squelch and Level Squelch levels.
The receiver has to be power cycled after a baud rate change for it to take effect. This is not documented.
Problems
The DCS code displayed and returned by the DS remote command during DCS search is incorrect. The DCS code is taken as decimal and converted to octal. The DCS code is already in octal.
Auto mode affects the FM audio when compared to FM mode. It sounds like the low audio frequencies are cut in Auto Mode.
VFO Search and Program Search do not resume if any delay is set. Free works okay. Setting a tone causes VFO Search not to stop on anything.
The only key colors are off and green. While doing keypress sequences during normal operation I think I saw the red briefly flash once or twice.
If the display is showing a menu and a remote command is send, the receiver keypad is not locked and the display does not change. The enter key exits the menu, but when the main tuning knob is turned, the previously active item in the menu is displayed. Pressing enter again will restore the display. Pressing clr to exit the menu does not have this problem.
Remote Command problems
MD command - Setting any digital mode other than Auto sets DSTR.
NQ command - Range of the squelch knob is 0 to 100, but remote range is 0 to 99. 100 is reported as 0.
AG command - Range of the volume knob is 0 to 100, but the remote range is 0 to 99. 100 is reported as 100.
RG command - Range of the RF-G knob is 0 to 100, but the remote range is 0 to 99. 100 is reported as 100.

Hello,
Some additional observations...
Memory Scan has the same problems with delay and tone as VFO Search.
The audio sounds different in Auto mode versus FM mode because of the de-emphasis applied to the audio in FM mode. This is a standard noise reduction technique where pre-emphasis is applied to the audio before it is transmitted in Analog FM mode and de-emphasis is used to remove it along with high frequency noise. It seems Auto mode is more of a Auto digital mode.
