DV4home DStar DMR dPMR NXDN C4FM

dv4homesmall img_2153

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

DMR UK Core talk groups

REVISED TALK GROUPS
There will be several changes to talk groups affecting

TG8, TG2350, TG2351, TG2352, TG2353, UK Wide & Direct Dial
As of the 28th December 2015 the new Talkgroup structure has now been implemented. However the new regional groups will not be linked to TG8

This is to allow users time to update their code plugs and test them on the new talk groups

Talk groups TG8, TG2350, TG2351, TG2352, TG2353 & Direct Dial
are still available, but will be switched off on 31st January 2016
AS A GUIDE THE REVISED TALKGROUP LISTINGS SHOWN BELOW ARE NOW CONFIRMED AS OPERATIONAL

FOR UP TO DATE INFORMATION PLEASE SEE THE LINK UNDER THE FULL TG LIST TAB AS WELL AS AGAINST EACH REPEATER LISTING UNDER THE REPEATER TAB

Despite the talk group restructuring having been completed, there could be some “fine tuning” to be done over the next month (and beyond) as Keepers can request additions and removals. We will keep posting updates on the relevant pages on this site as well as via the Facebook page and Twitter. Also via our weekly newsletter

~~~~~~~~~~~

An update from the c-Bridge Admins

** As of 09/01/2016 the process mentioned below has now been completed and hold-off timers are now operational on all wide area talkgroups **

As promised we have started adding hold-off timers to the wide area talkgroups on Timeslot 1. This has already been implemented on the new regional 8xx groups on Slot 2.

‘Wide Area’ means TG1, TG2, TG13 and TG235. As has always been the case these 4 talkgroups will still normally be heard on all repeaters. Users can continue to use them as they always have.

If a repeater user makes a transmission on one of the user activated talkgroups (TG80, TG81, TG113, TG123, TG119, TG129) or local TG9 then the 4 wide area talkgroups will be turned off on that repeater for 10 minutes (5 minutes for TG9). This will allow a user activated or local QSO without the risk of being interrupted by the wide area groups.

The wide area talkgroups remain active and usable on all repeaters not involved in the user activated QSO. Any of the wide area talkgroups can be reconnected immediately without having to wait for the timer to expire by keying up on that talkgroup.

A similar scheme will be implemented on the slot 1 special talkgroups such as 803. TG1 and TG235 are currently working as above. TG2 and TG13 will follow shortly

~~~~~~~~~~~

TALK GROUP 8xx (ROAMING)

Repeaters will be assigned a “home” region which is always on and is based on the repeater location. Secondary regions are available as a User Activated option. The reasons for the change include (1) it allows linking of repeaters with coverage in multiple regions (2) allows for qso’s to continue should a user go into the next region subject to availability on the next repeater (3) allowing the split of regions such as SE England which has grown to big for TG8

TG800 – RESERVED FOR FUTURE USE

TG801 – METRO EAST (HERTFORDSHIRE / EAST LONDON / ESSEX / KENT)

TG802 – METRO WEST (CENTRAL & WEST LONDON / SURREY / SUSSEX)

TG810 – SOUTH WEST ENGLAND (THAMES VALLEY / BRISTOL CHANNEL / SOLENT)

TG820 – NORTH WEST ENGLAND

TG830 – MIDLANDS

TG840 – EAST OF ENGLAND

TG850 – SCOTLAND

TG860 – NORTH EAST ENGLAND

TG870 – WALES & MARCHES

TG880 – NORTHERN IRELAND

TALK GROUP 2350 – 2353 (SPECIAL LINKS)

These groups will change talk group number – their function remains the same – their new TG number basically puts them within a “regional” block

The repeater listing will show “current special links” and “revised special links”

TG803 – Replaces TG2352 (GB7AK, GB7EP, GB7EX, GB7HR, GB7IK, GB7LO, GB7NS & GB7SE)

TG821 – Replaces TG2350 (GB7HM, GB7FW & GB7LP)

TG822 – Replaces TG2353 (GB7BR, GB7CA & GB7PN)

TG841 – New Talkgroup (GB7DS & GB7MK)

TG862 – No change to this talk group (GB7HS, GB7HX, GB7LE, GB7MR & GB7TD – M62 MOTORWAY)

TG871 – Replaces TG2351 (GB7HM & GB7PN)

UK ONLY USER ACTIVATED UK WIDE

To help with nation wide QSO’s especially as direct dial is suited for one to one QSO’s, two UK Wide User Activated talk groups are being implemented.

TG80 – UK Wide User Activated 1

TG81 – UK Wide User Activated 2

DIRECT DIAL (TG901 – TG940)

All direct dials will be removed from the network as part of the change and the UK Only User Activated Talk Groups can be used in it’s place.

USER ACTIVATED TALK GROUPS

The c-Bridge admins are working to add “hold off timers” which will assist users of these talk groups to hold on to the talk groups by inhibiting the other talk groups from taking the slot if the User Activated Talk Group is in use on a repeaters. This will be a new function that will be worked on to make using the UA talk groups easier for all.
