Great product   Time owned: 0 to 3 months
Just starting to use the digital modes, FT8 in particular. Purchased the Traveller USB from Johnny. Shipping was fast and communication has been great. I'm using the Traveller with a ft-817 and a indoor mag loop and it's working great and was very easy to setup. Highly recommend.

Great Interface !  Time owned: 0 to 3 months
I was never interested in digital modes, but with this Solar Cycle at the bottom and hearing nothing, I decided to give it a try.I was just about to build one myself, starting everything from the scratch, when looking on the e-HAM reviews I found the one build by Johnny, G3LIV. More than that, the cable for the 2 radios FT-2000 and FT-450D were available. Just thinking again how much time I have to spend to buy the components, making the cables, and getting the right enclosure, as I usually do,I gave up.
The Isoterm Traveler Interface worked perfect right from the box when all the required configuration was finished. Highly recommended.

Perfect!  Time owned: 0 to 3 months
I use this with a TS2000x and an IC746.

Firstly the driver installation for the USB com port worked perfectly.

The audio pass band is flat where needed for JT65/MSK144/FSK411.

The adjustable level controls are more useful that you might think. Far better to use a real potentiometer than some poorly implemented DSP windows mixer 'volume' control. Leave them at max then they cannot mess around with your audio with the possibility of truncation errors. This can be important for EME for instance.

Beware interfaces with integrated audio codecs, these are often of a poor quality.

I tested mine with a Behringer UMC202HD audio interface and a Focusrite Scarlett interface.

No noise, very important for the true weak signal operator.

Convenient size, solid construction and simple wiring.

Versatile USB comms interface..  Time owned: 3 to 6 months
I had a predecessor model 10 years ago. I have been QRT for that time and was delighted to discover that Johnny is still producing these units. The interface works very well with my Kenwood TS2000 & Icom 7300. I'm using it for JT65, PSK31 and WSPR. Solid performance in all modes. Johnny is always available to discuss various applications and has been a great help. Great product, sensible price.

usb dual deluxe great unit  Time owned: 0 to 3 months
I bought the usb dual deluxe last month and it works very well. I connected it to an Icom 775 DSP and to an Icom 910 H. The two cables needed for the two radios arrive with the unit you purchase together with a usb cable the t connects the PC with the unit and another cable necessary to connect the usb dual deluxe to the sound card.
I also bought on the internet a usb sound card for a couple of bucks so that i use it only for amateur radio staff.
you gotta contact Johnny telling him the radios that you're connecting the unit to.
Johnny is very kind and patience and i wanna take the occasion for thanking him again.
If you buy his products you are not going to make mistakes.

Great unit Supper Comms. and help.  Time owned: 0 to 3 months
I have just purchased a Isoterm-Multicon Interface for PSK31 from Johnny G3LIV. Before doing so I contacted Johnny re the unit and certain problems I thought I may have using it. Nothing was to much for Johnny who helped me sort out my worries. After ordering the unit it arrived next day and after reading the enclosed booklett very carefully and following the suggestions the unit fired up and worked perfectly. If you purchse one I can not stress enough to read the instructions well. All in all a great unit with 100% backup. Thanks Johnny.

usb Isoterm-Multicon Interface with Linux Computer  Time owned: more than 12 months
Having enjoyed PSK31 using the usb Isoterm-Multicon Interface with Digipan under the Windows Xp operating system, I was keen to use an older computer with a Linux operating system.

The usb Interface works well under the Linux Ubuntu v14.04 operating system (includes CP2102 driver) with Fldigi (Linux v3.21.80-1) giving me the option of more digi-modes. Both programs were downloaded and installed from the Ubuntu Software Centre. Audio to and from the rig worked immediately. However, for this version of Linux, it was necessary to run a command to add your "username" to the "dialout" group to activate the PTT link.

Lovely bit of kit  Time owned: 0 to 3 months
Having struggled with a home made PTT cable for my FT897 I was always fighting the ALC levels on my rig when using digi modes, particularly after starting to experiment with JT. I contacted Johnny about his product and the responses were so helpful I knew I was onto a winner, so I ordered one - it was delivered within 48 hours!

The product is well made and a delight to install - anyone can do it. It comes with all pre requisite software and installs easily. The instructions are so clear that, if like me you hate digipan (the recommended program) its easy to apply the correct settings to your program of choice.

Its an absolute treat to have such fine control over a signal going into the rig - couldn't do my digi work without this now!
