I’ve only had mine a few days and have really enjoyed it. I’ve been interested in one since I heard about it a couple of years ago, but waited to buy until the firmware and software upgrades were made available for the US version.

I expect there will be further firmware and software updates in the future, albeit slow. HRO has listed spare battery, desk charger, AA battery case, soft case, and spare antenna. I think that’s all the accessories for the radio.

If PC (Windows, see device manager - is there a yellow exclamation mark) fails to recognize USB device (DJ-X100E) one thing maybe worth trying is to use usb serial adapter connected to usb-to-null-modem adapter, connect usb2serial to Alinco and usb-null-modem adapter to PC.

e.g. "USB to serial adapter (Aten UC-232A) + USB serial null modem adapter (S6618, cheap device from eBay)."

Have you ever tried to delete the channels in the skip database? When doing so the scanner freezes in some special situations.

Yes, deleting the skip channels is a nightmare. Once I had to wait several minutes before the radio recovered.
Also, my first observations regarding reception are not very good. The receiver is very sensitive not only to radio signals but also to noise and interference. And AM is a nightmare- except very strong signals, the audio is hard to understand, when signal is weak. Compared to IC R30 on airband, the Icom is 100x better. On FM bands, the RX is slightly better than on AM but there is still the problem with high sensitivity to interference. It is an SDR inside so it is to be expected but I really hoped for better filtering.

P25 is a very costly option. To expensive for the japanese market.
Same with TETRA.
Outside of europe, TETRA is not used much, and most of those systems are encrypted anyways.

I just received an email from RT-Systems... They have a programming software out. 25USD.. First impression.. worth every single penny! (my personal opinion)

URI DJ-X100

Cheers

It doesn't have dPMR in their mode options. Importing my Alinco into the software, it ignores my dPMR channels. I've emailed their support to let them know.

RT-Systems have released two updates to add dPMR and fix a further issue with save files with dPMR in them. They are quick to fix, and very responsive :)

I am looking into a possible hex edit of the software to push the upper frequency limit past 470 MHz. In my area, even 475 MHz would allow a slew of additional monitoring. I think it might be possible if one knew where the frequency limits are stored.

May I correct you? It’s not that important unless you actually license the hardware or software codec from DVSI.

C4FM is basically a derivative standard, and adding P25 would’ve been easy. Open-source P25 implementations already exist on GitHub and in other public projects, so that wouldn’t be a problem. Plus, P25 is the number one public safety standard in the world by the number of systems and users (except for China, probably, where they have their own standard and codec, PDT). That’s why radios like the AOR DV1 and DV10 support it, and AOR is just as much a local manufacturer as Alinco.

I agree about TETRA. It’s complicated to implement and not really needed in North America or Japan.

But skipping P25 was a mistake. Without it, I’m not interested. I don’t care about C4FM, but if they ever add P25, I’ll buy three to five units right away for myself and some friends.

You're forgetting one thing.. The DJ-X100 was primarily built for the japanese market, The European and US-Version are an add-on to lower the per-unit cost of the hardware. The only P25 Systems in Japan (to my knowledge) are the US-Bases (same in Europe, plus some ham-operators). In Europe Law-Enforcement, Fire, and Rescue are on TETRA (Fully encrypted). Businesses in germany run on DMR,dPMR, or Analog. Some public transport systems are on TETRA.
Most Japanese governments, police and fire, self-defense forces and ex-national railroads use Japanese-made CODEC such as CELP and other formats that receivers are not available for public. Most land mobile use DCR format, that is a cousin of NXDN and dPMR made by Icom and JVCK

Hello, just to chime-in about my latest acquisition : DJ-X100E.

The radio is on version 4.00-04 DSP 1.07 AMBE 009.
AIS and ACARS works correctly, dPMR is available on the radio and in the CPS software (even if it as no use for me, i just wanted to add this info for others to see).
The special code opening the "maintenance" menu works OK too.
But no dice for the SC and POCSAG special code punched into the CPS while displaying the version info, no POCSAG menu appears after doing this and uploading the config to the radio.
The radios has very good decoding of DSTAR, C4FM Fusion, and DMR (displaying TG).
Its a nice "plus" being able to monitor the 3 ham modes on a single radio !
But i really hope someday Alinco will allow us to enter a series of TG to monitor in DMR mode, as for now it is "ALL" or any single TG we can enter, but no series of 2 or more TG.
The audio leveling/amp/eq works wonder !
The battery life is more than adequate, giving plenty of listening for a whole day without problem.

But i have no luck so far in decoding NXDN 4-channels trunked site programmed as 4 individual channels, either in NXDN(N) or NXDN(VN); I must say that this system has conflictual info posted, whereas it is identified as a 9600 NXDN system, but where my BCD436hp tells me it is a NX4 system.

On the unit itself the TG can be programmed.
As for software to programm the unit, I use the software from RT-Systems. It also let's me set the TG.

Ok yes, thanks for the cue about the tg setting on the unit itself !
I too, have bought the RT Systems software, nice addition (as like other versions I have for different radios), but haven’t explored it much yet.

I only wish we could enter a few TGs, aka the concept of « TG Lists » on other brands / models of radios / scanners.

For nxdn same here no luck to decode 5 channels...Even my other Uniden s can decode all the way...

Hello!
I am about to purchase a Radioscanner, but I still have doubts about which one to choose: the Alinco DJ-X100E or the AOR-DV10 (DV-10´s units starting with the AA6336XX series manufactured from 2022, which I understand no longer have frequency stability issues).
I should mention that I live in Germany. So, I am not interested in TETRA (everything is encrypted in Germany), APCO P25, or trunking.
Which one has better reception for: AM, FM, dPMR, DMR, D-Star, FM-Fusion, C4FM, and possibly NXDN?

Is there anyone who owns both radios and could advise me? Thank you in advance!
