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.

Earlier 5-star review posted by M1ASR on 2002-05-17

I use this interface with PSK31 & SSTV with good and consistant results, irrespective of rf power levels used.

I plugged the Isoterm into the 13pin ACCY 2 socket on my TS2000, connected the 9 pin D into the RS232 port on the PC, set up the audio levels and forget about it!

I would advise that leads all still kept as short as possible and if you need to extend them, ensure that high quality metal 3.5mm Stereo plugs/sockets are used.

I've had PSK copies all over the globe on 10Watts.
Johnny (G3LIV) gives excellent support and advice.

Regards & 73's

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!

If everything in life was this easy! Time Owned: 0 to 3 months.
Ordered Monday late afternoon, arrived Wednesday morning!! Have to admit I am a newbie to DATA modes and wanted to make the best of a new mode. M0OXO brought an old version along to MC0SHL EU-124 trip to Ramsey this year (2015)and I was very impressed with how easy it was to setup. As soon as I got home I looked up Johnny G3LIV and promptly ordered the USB Deluxe Dual. A I said before I am a newbie BUT in under an hour I had both rigs setup and TXing/RXing via Logger32 MMVARI.

Thanks Johnny for a great product.

Very satisfactory equipment and well made to a high standard. Don G0RQL.

Top product from a Top Ham Time Owned: 0 to 3 months.
Excellent product, beautifully made, but the best thing of all is the excellent support and practical help in true ham tradition that you get from Johnny.

I got the USB Traveller version and it is seriously cute for portable use but is equally at home in the shack too.

Compared to similar units it is even less expensive, meaning Johnny's offering is a winner on all fronts.

Totally recommended!
