At xggcomms.com, we offer a range of different Ham Radio interfaces and Test Equipment related Products.

If the Digimode-4 does not suit your needs (you may already have a CAT cable for example) we also offer other interfaces that give you just the Tx/Rx audio and PTT features. All with the external USB audio device dedicated to Digimode operation.

We also sell a range of CAT control cables for the main manufacturers and one of our latest additions is an OCXO upgrade for Racal Frequency Counters.
