NBEMS – Fldigi, DMR and Anytone AT-D878UV

by

Fldigi is multi platform software to send and receive msg Flmsg or file Flamp via Analog two-way radio using Mic/Speaker connectors with no special HW.

It can be use as NBEMS – Narrow Band Emergency Messaging Software on VHF/UHF and on HF.

Anytone AT-D878UV could be used with Bluetooth functionality or with Kenwood connector to interface with Microsoft Surface 3 or even with Raspberry Pi in Radio GoKit scenario.

HAMlib library can manage interface with serial portal and send PTT input.

Anytone AT-D878UV connected to PC via Bluetooth

On Windows 10 PC, go to Settings -> Devices -> Bluetooth -> Add Bluetooth or other device.

On Radio, go to Menu -> Bluetooth -> BT On (to enable) and BT Pairing -> Available BT -> Select name of PC

Pending HAMLib module for AnyTone

HAM Radio kit and Tesla Model 3 antenna

by

After few days of planning, I’m switching to new configuration for car and home.

Advantages of new configuration are:

  • Antenna in car is smaller (rom 38.2″ to 13.8″) and still support up to 100W output
  • New car antenna is compatible with NMO connector already in car
  • Mag Mount is heavy to keep existing antenna stable with NMO connector and it can be used home, carry around as external antenna for HAM radio Go-Kit or stored in trunk of car of need more coverage.

Here is final setup:

DIAMOND K400CNMO Trunk/Hatchback Mount

NR770HNMO Dualband Mobile Antenna

  • Bands: 2m/70cm
  • Gain dBi: 3.0/5.5
  • Watts: 200
  • Height: 38.2″
  • Mount: NMO
  • Element Phasing: 1-1/2 Lambda, 2-5/8 Lambda

Antenna is installed on right side of car connect to trunk edge via K400.

K400 0978dia2

Cable is routed as follow:

  1. Under the moving part of trunk toward front of car (photo #1)
  2. U turn back down to bottom of fixed part around the rubber insulation used to protect wiring in the truck (photo #2 and #3)
  3. Inside trunk and stick on top of it to avoid any hanging (photo #4 and #5)
  4. Move down following the back of right seat and around the seating part (photo #6, #7 and #8)
  5. Under all weather floor mat to the area between central console and front passenger seat (photo #9 and #10)
