70cm Spectrogram

A 400MHz - 470MHz low noise amplifier was used with a 5 volt power supply.

The repeater has a center frequency of 446.5 MHz and is 7 MHz wide.


Hardware in 2017

During 2017 some updates were made to the hardware configuration for the incoming DVB-T signals.

The existing VHF/UHF Diplexers and 70cm Low Pass Filter where retained.

This allows for the ATV Checker and separate reception of VK3RTV1 and VK3RTV2 using independent DVB-T dongles.

The first DVB-T USB dongle is for the ATV Checker program using DVBScan to monitor the repeater. This is installed on a separate old Raspberry Pi Model B+.

The second and third DVB-T USB dongles are independent feeds to TVheadend running on separate Raspberry Pi 3.

The three Raspberry Pi are mounted using a Raspberry Pi Stack.

Kodi Frontend.

Due to the ending of support for Mythbuntu. I migrated to the Kodi platform.

Recordings

There is a recording button available on the Kodi front end.

The directory where recordings are stored is set in the web interface of TVHeahend.

Using a networked drive I have mapped the /mnt/recordings/ folder for storage to hold recordings from either channel independantly.

The /etc/fstab file is edited to set up on boot the /mnt/recordings/ folder for storage to hold recordings from VK3RTV1. The same is done for VK3RTV2.
