Multi Mode Digital Voice Modem
So do you want a cheaper option?
What you will need
A MMDVM (Multi Mode Digital Voice Modem) is a link from your wires-x capable radio to a room on the wires-x system – allowing you to speak to other hams.
This can be particularly useful when out and about as you don’t need to link your radio in PDN mode to a laptop
The Software (Operating System) runs on a small computer called a raspberry pi
There are different models and sizes from the small pi zero to the full sized pi – these can be used as a desktop PC giving them more then enough processing power and features to run pi-star

Well for around £70 (fully assembled) you can get a small MMDVM JumboSpot; running pi-star
Where to get an MMDVM
You can buy there from many places – including our shop.
Would you like to have a look at the pi-star software?
You cannot change settings; it will show you an error, but you can get an idea of a WIRES-X setup.

This little box allows you to connect a WIRES-X digital radio to the WIRES-X network and talk via any WIRES-X digital radio.
I had it up and running in minutes and tuned into CQ-UK
So whats in the tiny box?
- Raspberry pi (zero/ 3b)
- OLED screen or nextion screen
- MMDVM HotSPOT Module
- micro SD card
This is all neatly packaged in a 7cm x 3cm x 3cm (approx) case
- 5 Volts DC
- 0.18 Amps (± 0.03a) (idle) *
- 0.25 Amps (± 0.03a) (transmitting) *

This setup up is almost the same a the small oled screen, just with a customisable 3.2″ screen
I find one of these on me desktop it great especially as it tells me where the call sign is from
