Amateur radio (also called ham radio) is the use of designated radio frequency spectra for purposes of private recreation, non-commercial exchange of messages, wireless experimentation, self-training, and emergency communication. The term “amateur” is used to specify persons interested in radio technique solely with a personal aim and without direct monetary or other similar reward, and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government’s radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.

Amateur radio is officially represented and coordinated by the International Amateur Radio Union (IARU), which is organized in three regions and has as its members the national amateur radio societies which exist in most countries. According to an estimate made in 2011 by the American Radio Relay League, two million people throughout the world are regularly involved with amateur radio.[1] About 830,000 amateur radio stations are located in IARU Region 2 (the Americas) followed by IARU Region 3 (South and East Asia and the Pacific Ocean) with about 750,000 stations. A significantly smaller number, about 400,000, are located in IARU Region 1 (Europe, Middle East, CIS, Africa).

DV4home DStar DMR dPMR NXDN C4FM

dv4home

DV4home – Shipping again beginning of December

The DV4home is another member of the successful family of DV4 products. As usual it supports all digital modes, while simplifying and extending the supported functions. While it acts as a “home” for the DV4mini it can be easily used mobile or portable as well. It is a stand alone unit that does not need a PC to operate. (DV4mini not included)

(automatic update of firmware via Internet)

There are 2 versions available, the DV4home and the DV4home compact.

DV4home

The DV4home uses the same microcontroller platforms as the DV4home compact, but adds 2 AMBE3000 chips, a microphone and a speaker connector to the unit. There is a built-in speaker and the microphone is included.

These components allow these additional functions:

  • Direct Internet transceive mode without a DV4mini by using the microphone and the external speaker. This is an economical alternative if no local wireless signal is needed. In this mode the DV4home supports D-Star, DMR, dPMR, NXDN (and later C4FM via software update)

  • Dual mode support: even without a DV4mini inserted the unit can be simultaneously connected to a D-Star and a DMR reflector, using 2 separate speakers to play the respective audio streams.

  • Transceiver mode connects a D-Star or DMR radio via a plugged in DV4mini to a reflector.

  • Conference mode requires a DV4mini inserted into the unit and allows to use the built-in microphone/speaker connectors and the RF connection through the DV4mini to a DMR or D-Star radio. This mode works in D-Star and DMR.

  • Transcode mode allows to use a digital radio in one mode and connect to a reflector in another mode. Use your D-Star radio to try out DMR! The following conversions are supported:

    • D-Star → DMR

    • DMR→ D-Star

  • Later via software update:

    • All –>. Fusion (C4FM)

    • Fusion (C4FM) → All

  • DMR/D-Star Bridge mode allows to interconnect DMR and D-Star reflector rooms using the licensed DVSI AMBE chips. This mode bears the risk of creating loops in the network, therefore a free license key is required which also helps that the installations can be supported by the network administrators to assure a flawless integration.

  • IPSC2 and DMRplus bridge permits the connection between DMRPlus.

DV4mobile digital triband transceiver LTE

dv4mobile

DV4mobile – first all mode digital tri band transceiver plus LTE with GPS

 

  • The DV4mobile supports all digital modes: no need for multiple radios, saving space and money.
  • It is programmed from the cloud: no need for programming and updating code plugs.
  • It is a software defined radio: future modes are just an update away.

 

The DV4mobile is another member of the successful family of DV4 products.

It operates in the 2 meter band, at 222 MHz and the 70cm band.

All modes are supported: C4FM, D-Star, DMRplus, dPMR, P25 (NXDN later via software update) Voice over LTE and of course, FM!

C4FM both narrow and wide band modes

D-Star (DCS,CCS,REF,XRF,XLX)

DMRplus (TS1 all / TS2 Reflectors or talkgroups)

dPMR(All Systems and codecs transparent mode)

P25(Phase 1 Only and all NAC transparent mode)

FM with PL and DCS tones and RDS for call sign transmission in the background

DV4LTE is a new voice over LTE mode that connects the radio to the reflector using an LTE connection.

The LTE modem connects to the CCS7 reflector system supplying  codeplugs in the cloud, there is no need to program codeplugs any more. Any changes in the network, be it on the reflector, repeater or user side are instantly updated. Private settings such as local channels can be maintained on the web.

After a reset or with a new radio all settings are downloaded after entry of the CCS7 number.

When no repeaters are in range, the radio can revert to LTE (DV4LTE) for reflector connection (i.e. between metropolitan areas)

 The GPS module provides location data for APRS and automatic display of repeaters in range. When a repeater is selected, frequency and mode is already in the radio, no programming!

Simplex repeater mode

 The DV4mobile can also be used as a dual band, dual mode simplex repeater.

For example you can use it as a D-Star repeater on 2m and simultaneously as a DMR repeater on 70cm while conducting  FM QSO on 222 MHz (USA version only)

 The extreme temperature range from -40C to +85C ensures functionality even under the most extreme conditions
