* 80W until 53MHz, then output power is slightly decreased

** These functions are supported by the transceiver’s hardware, but is not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.

Expert Electronics ExpertSDR2 Software:

The ExpertSDR2 software package is used to control the SDR transceiver. In receiving mode the software provides two independent receiving channels with up to 312 kHz bandwidth. Each receiver has its own sub receiver. ExpertSDR2 runs under Windows XP/7/8/10 x32 or x64, Linux Ubuntu x64 and MacOS (MacOS currently beta). Minimum hardware requirement Intel Core i3 1.6GHz or higher, video card supporting OpenGL 1.5 and RAM 256 MB or more.

Expert Electronics ExpertSDR2 System Requirements:

  • 2 or 4 core CPU Intel Core i3 or Core i5;
  • 8 GB RAM;
  • 40 GB free space on the HDD/SSD for the ExpertSDR2 and accompanied programs;
  • 17′ or bigger monitor;
  • video card with OpenGL 1.5 or higher;
  • ExpertSDR2 supports Windows 7-10 32/64 bit, Linux (Ubuntu/Kubuntu 18.04 x64), and macOS 10.14 Mojave and higher.

Expert Electronics SunSDR2 DX box contains:

  • SunSDR2 DX Transceiver
  • LAN-cable 1.8m for connecting to local network
  • Power cable 2.0m for connecting to power supply
  • Two 6.3mm phono male to 3.5mm phono female adapters to connect a headset to the radio
  • Mini UHF (male) to SO239 (UHF/PL female) pigtail adapter with 30 cm  RG58 coax
  • External fan

Does it contain adapters for the mini-UHF to PL259/BNC?

Box contains one pigtail cable (cca 30 cm) that converts MiniUHF to SO239. If you want to use more than one antenna port, you may need to custom-make further similar pigtail cables or patch cables with MiniUHF on the radio end yourself. MiniUHF connectors, H155 coaxial cable and crimping tool are available from the Anico hamshop (check optional products). MiniUHF-SO232 adapters without pigtail cable are also available, however these adapters need to be used with special care (for explanation see video: )

TCI macro for Expert Electronics SDR:

SDR radios have no control panel, therefore manufacturers do not supply a user manual. Our company only sells SDR hardware; operation of these devices requires various software that you can download from the internet.  Most of these software products are only available for download in the English language  from the websites of manufacturers and third party developers (many of them radio amateurs) either for free or for a fee.  Installation, setup and usage of the software require an intermediate level of proficiency in computing and the English language. We do not advise to buy these equipment unless you are in possession of these required skills, and we highly recommend to seek assistance and prior information from other radio hams on internet-based forums and user groups.

I got a sunsdr dx2. Perfect delivery both in terms of timing and packaging. Initially I found myself in difficulty with the payment, I sent an email and they replied immediately, telling me what to do. I definitely recommend any purchases from you
Thank you
The web shopping was very easy and the contact with Alexandra, wonderful. I can only recommend to shop in Anico.
Yesterday I have received my brand new SunSDR2 DX. Although the delivery of UPS took11 days (NOT Anico's fault!), it arrived as promised (UPS said from the beginning that it would take 11 days). It arrived in perfect condition and the rig is already up and running.
On my MacBook Air with M2 processor, OSX 13.0.1 Ventura, first of all I created a new Network Service, which I called SunSDR2 DX, based on the Ethernet hub I have (QGEEM 11-IN-1 USB C/3.0 HUB WITH VGA) and defined the IP address manually and with NetMask, the same as explained for Windows.
I connected the rig via ethernet to the hub that was connected to my MacBook Air and Expert software recognized the rig immediately, both legacy v2 and new beta v3. At first I was asked by v2 (I started with v2) to upgrade firmware, which I did immediately. Then I started to learn how to manage the ExpertSDR2 software.
I have sound in both versions, v2 and v3, on my computer's sound card and, of course, also directly when connecting the headphones to the PHONES output of the rig.
I have not yet tested transmission, but this will come next.
This is definitely a new way of making radio.

I have to say it is an outstanding equipment for the price and very reliable. The only concern that I have is, to me, in questions of hardware seems a bit fragile. I am writing it because mine had a problem and went to Russia to be fixed and up to now I am not aware what I did before to cause the problem. Apart it it has been working very well.

I discovered Anico Hamshop by accident while surfing for the SunSDR 2.

The fact that the SunSDR 2 DX was offered at a much lower price than other dealers and the fact that Anico is an authorized service center convinced me to order there.

Shortly after placing the order, I received the invoice, which I paid in advance.

Communication was excellent and I was kept informed of every step of my order.

Shipping via GLS was smooth with tracking and a time window of 2 hours.

I ordered on Monday and already put the SunSDR DX into operation on Friday.

I am very satisfied and have had a good customer experience, I would order there again at any time.

After ordering the SunSDR2 DX, I neatly received the invoice by email. After payment the set was immediately shipped and was received in the Netherlands within 5 days. Despite all the "hectic" at the moment.

Thanks for the good service!

Was fast, safe and perfect. Only thing that was not satisfying, was the speed of GLS in delivering. But they are known for that. Next time I want some equipment, I will look at anico's first. The prize is ham-friendly!!

The processing of the purchase of the device was professional and without delay . Article was delivered as described . The
Shipping to Germany was via GLS and arrived undamaged .
Conclusion: I will gladly buy again from ANICO.

Note : The device was in the original packaging in a film
shrink-wrapped, delivered. In order to avoid possible damage to the original packaging (for resale is gladly placed on an undamaged packaging value) it would be better to pack everything again in a transport box.

I've purchased a SunSDR2 DX from Anico shop in Hungary. I had a very positive experience in dealing with Adam. He was very responsive in guiding me through the purchase process. He shipped the radio the very same day funds were transferred and it arrived in two days from Hungary all the way to Canada.
I highly recommend their store.

I highly recommend purchasing from Anico.
This is my first time dealing with Anico and its 100% beyond satisfaction. I order the SunSDR 2 DX online and because its shipping to Asia, requires a manual shipping quotation and there after wire transfer payment to Anico's account.

I have daily communication with Alexandra Lorincz via email on the status of my wire transfer. The package was immediately shipped upon receipt of my funds. Alexandra impresses upon me that Anico takes this business very seriously and client satisfaction was achieved. I probably contributed only to a very tiny part of this business and yet they took my 1 single order with pride.

This is a company i highly recommend we purchase from and a company is only as good as its professionals hired, thank you Alexandra.

Please share my wonderful experience with your organization in any way you deem fit.

The order went flawlessly, I received my SUNSDR2DX after just 3 days after I ordered it. But honestly I still have problems with the software. I'm used to SDR Software, e.g. SDR Console which I'm using for years is very easy to operate. The SunSDR SW is so different, It's difficult to adapt. After two weeks of trying, it still does not behave the way I want it.

Recently purchased the new TRX. First, the company Anico is very serious. They do work fast and efficient and they do respond to your emails. The product received quickly. Now the machine. Great job, great 1st impression after unpacking. Very easy setup, PnP basically. Download SW, connect, adjust the ports and here we go. 2DX works great, have it connected day and night for testing, no glitches whatsoever, so many options. Still have to learn but the impression is truly good. I am sure I did not go wrong with 2DX. I will try to update the post after having a couple of QSOs passed. 7d de Rudy
