Ve6fi Amateur Radio

 

 

Remote Station set up

 

General Description of Remote Station

 

December 2017 update - We plan on  using remoting software  to access the data and use Remaud  for the analog audio on the internet. Presently we are using Skype but will be moving over to Remaud when we establish the permanent 2.4 GHz link.  Presently we are tied into a neighbors wifi but that is not working out because of capacity problems of their ISP

The idea of the remote station is to be able to operate the station VE6FI from home in Edmonton about 20 km away. This would allow using the antennas, radio and amplifier at the Ve6FI site without being at the site itself. One of the requirements was to have a reliable system that had some fail safe devices in case something did go wrong.

This version of the remote incorporate the use of a FT1000MP transceiver, all the antennas at VE6FI and the solid state auto tune Harris 1 KW solid state amplifier at VE6FI.  The software used at the remote site would be TRX manager.

TRX manager runs on a computer at the remote and the computer is connected to the 1000MP by a standard serial port. TRX manager communicates with the 1000MP and allows one to change frequency, change band, change filters and various other controls. The output RF signal of the 1000MP goes to a Top Band decoder box that will switch to different antennas as the 1000MP changes bands. The 1000MP interfaces to the Top Ten decoder box by propriety 4 level code. For example when you switch to 40 meters, the Top Band decoder will switch the input to the 40 meter antenna.

At the home station (Edmonton) I run  remote software that  allows one to see the remote screen at the home station.  From the home station you connect   to the remote computer which answers instantly and provides the home station with a complete screen identical to the screen  at the remote. Thus you have control from the home station to tune, change bands and change all the controls as if you were sitting beside the computer at the remote. To key the transmitter you press the key button on the screen and the 1000MP will key.  (see the wifi link)

 

Now there are other circuits that have been  develop to allow the following:

  • Additional antenna selection (LPT board)
  • Linear amplifier interface
  • Relay box to wire in the additional antennas
  • Power supply to supply the various voltages at the remote
  • Correct keying sequence
  • Visual Basic software that allows selection of additional controls
  • Cable interface box to the linear amplifier
  • Home stations setup

 

Below is a screen shot of what I have at home or via the internet on my laptop when I am operating the station at ve6fi. Note that there is control of the radio via TRX Manager, There is the bottom panel which monitors the instantaneous power output of the transmitter. The remote pick up and software is provided by WaveNode. 

On the right side of the screen is the Visual Basic graphics which controls selection of 1 of 5 antennas on the band one is operating. It allows the Amplifier to be turned ON, Switching power to the towers, controlling two rotators which have larger monobanders on them.
