If your Laptop or desktop only has an "Earphone" jack, but no "Mic" jack, read your manual! It probably has the combined Earphone/Mic jack.

This is a 4 conductor jack wired as follows: TIP, RING, RING, SHIELD: Tip = right channel audio out. 1st Ring = left channel out. 2nd ring = ground. Shield = microphone input.

When you order I need to know whether or not your device is as above or uses the legacy separate mic and earphone jacks. If you do not give me that information then I can not guarantee that what I ship you will work on your pc and if post shipping modifications are required you will be responsible for shipping costs both ways as well as a modification fee.

I also need to know the make and model of the radio you wish to use the interface with and whether you wish to use the microphone/speaker jacks or a data or accessory jack.

There is a link button on every listing that says "Contact Seller". Please use that to send me your information 

Includes two (2) or three (3) 1 meter long audio cables. If your setup is going to use a Data or Accessory jack on the radio, you will receive two cables, if your setup is going to use the microphone/external speaker jack, you will receive 3 cables.

Finally, no longer a need for USB to RS-232 Adapters!

This Easy Digi™ USB digital interface plugs directly into an open USB port on your computer!

In most cases, it will go out to the internet and find it’s drivers, install them, and tell you it’s ready to go!

A single driver CD is included!

We’ve tested it on XP, XP-PRO, VISTA, and WIN-7 with excellent results.

This interface can be configured to work on almost any HF or VHF amateur band transceivers!

While we have sold several thousand of the previous versions, this is a major step forward for our little interface with a minor step in pricing.

Nothing new about this technology, it consists of two 600 ohm line transformers for audio input and output from your pc to your transceiver, and an opto-coupled push to talk circuit that works off of a USB port on your computer.

• Transformer coupled audio eliminates ground loops and AC hum on your signal
• Opto Coupled push to talk circuit also eliminates ground loops and false triggering of your PTT lines.
• Very small size, only 3 13/16”L  x 1 9/16”W  x 3/4” H, can be mounted using the built in mounting tabs in just about any convenient location.
• Case made of durable ABS Plastic for long life.
• Built in USB Serial adapter, connects to USB port on any PC
• Built in microphone cable approx 18” long connects to any microphone connector.
• Weighs less than 3 ounces
• High quality FR-4 double sided, solder masked, silk screened Printed Circuit Board
• Compatible with most modern ham radio transceivers.

Please use it to let us know what radio make and model you want your interface adapted for and whether or not you want to use the accessory or data connector on the rear of the radio or to use the mic jack and external speaker jack. (In many cases, a radio may not have an accessory or data connector, please check your radio/manual).
