Supports Native USB Time Owned: 0 to 3 months.
I bought the DXP based on my experience with the Microham USB II interface I had used with DXLab and N1MM for RTTY contesting ten years ago. I purchased it directly from Microham in Slovenia. I initially had a few issues setting it up and getting the correct firmware settings internal to the DXP. I am using the DXP with a Kenwood TS-480SAT.

Great product , even better support Time Owned: 0 to 3 months.
I bought the DXP for my TS950SDX to utilize the audio off the accessory ports instead of the mic inputs on the front for digital modes. I was very impressed with the features and it definitely is in a league by itself. When I recieved my unit my DXengineering , I pluggged it up and found that the rig went into a protection mode and the transmit was inhibited because Port 9 on the 13Pin Din on the radio was being pulled down placing the radio ion transmit mode. This was most distressing , but, after I finally got in touch with the great people in Slovakia I began to believe there was a light at the end of the tunnel. I was helped by Jozef OM7ZZ , first I was pleased they are working hours which allow them to provde US support through our morning hours here on the east coast which is late evening for them. Jozef was very quick on responses to my emails and after several emails doing some trouble shooting the problem was found. It turned out on the oder radios like my Kenwood they have 12V on the pin 9 and after a recent design change to the DXP adding a safety protection Diode the 12v caused the protection circuit to activate. As Jozef explained on newer radios thats all 5 V but on older rigs its 12 and that was the problem. Jozef showed me the diode and I simply removed it and now I have a perfectly functioning DXP that I am loving. Sometimes I;ve been worried about buying products supported offshore, but in this case feel confident that whatever you need the MicroHam team will be ther for you. Thanks again Jozef .

Good, flexible and reliable....what else ? Time Owned: 0 to 3 months.
Hi guys ! I'm Mac user and with the latest macOS version (Big Sur) I went into toubles because SiLabs VCP driver was not updated and I had no chance to drive my FTDX101MP anymore.
So I purchased the DXP as the manufacture says it doesn't need any driver installed on any computer (Win-Linux-macOS) as if it was not OS dependant.
The result ?? I plugged the Usb cable into my Mac running "Big Sur" and in a while I found 3 new ports ready for use (CAT+Winkey+FSK) without touching my Mac....a real plug-and-play ! In addition it has a genuine Winkey 3.0 inside.
And it's not enough ... somebody connected the DXP to his Mac mini based on the new M1 Apple processor and the DXP worked exactly in the same way : plug the cable and play !
Extremely satisfied, not a cheap device but it worths the money !Thanks a lot microHAM !!! 73 Giorgio
Issue update: a friend of mine left-handed CW operator discovered that there's no way to swap paddle and make it permanent after DXP power cycling. As there's no command in the DXP menu for that action, the solution is to "swap" paddle wires in the paddle jack.....that's really a pity ! We hope microHAM will provide appropriate menu selection in future

Good product, easy to use Time Owned: 0 to 3 months.
I had previously owned a MicroHam Digikeyer that was at least 7 years old. I liked the Digikeyer but it had failed and I was looking for something new. I use Linux so making it easy to use on that platform was important. Many products including the MicroHam keyers and USB units use routing software to multiplex USB ports. This makes things more difficult to set up. The DXP is different. It actually has multiple USB ports on one physical USB cable that you plug into your computer. Set up was a breze on Ubuntu Linux. No special drivers are required in any OS. It took all of about 15 minutes to familiarize with it and get it up and going using fldigi. Cat and PTT work fine. I did not have to buy the cable for my TS570 as the former Digikeyer cable worked with it. If you had a former digital Interface product from MicroHam check the "no cable" and save some bucks. The DXP gets all its power from the USB connection. This is certainly not the cheapest digital interface out there but in my book well worth the cost.
