Just plug in standard PS2 keyboard and connect modem directly to SSB-capable transceiver. Other digital modes coming soon. Field-upgradable software. Graphic display shows Tx and Rx text data, band spectrum and tuning indication. Requiring only 60ma operating current (typ), the modem forms an effective, compact, and portable station for working the digital modes on the amateur bands. Comes with unterminated cable for connection to radio. (User must add connector for specific transceiver being used. See options for pre-made cables below.)

UPDATING SERVICE

Let Us Update Your Modem's Software & Hardware to the Latest!
The longer a successful product is in the field, the greater the need for general software updates and hardware mods to be done to keep things up to snuff.  Although we provide an easy way for modem owners to update things themselves, we'd be happy to do the updates & mods for you ... just
send us your modem and include a check or MO in the package (or click the appropriate PayPal button to the right)  and we'll do it pretty much just for the cost of return postage. And we'll turn it around within a couple of days upon receiving your modem in the mail.

The Standard Upgrade Services include ...
* upgrading the software to the latest release
* adding any hardware mods needed since the modem was purchased
* adding the recommended grounding of the pcb
* adding a capacitor on the power supply jack to minimize EMI/RFI
* a full test to ensure that the modem is fully up to snuff!

Special Needs? ... Let us know if you'd like us to help with any custom modifications you'd like done to your modem.  We'll be happy to work out a deal to help you out!
