Reception of VK3RTV Amateur Television using a shared roof top antenna and a Raspberry Pi stack.
Here are photos of VK3RTV1 and VK3RTV2 within a Kodi Frontend.

This page is an update of the page detailing my reception of VK3RTV using a Raspberry Pi 2.

A 400MHz - 470MHz low noise amplifier was used with a 5 volt power supply.
Here is a frequency spectrogram of VK3RTV operating in the 70cm amateur band received using the above Low-Noise Amplifier and a rtl-sdr dongle.
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.
The two way signal splitter was replaced with a three way signal splitter.
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.
The Model B+ for the ATV Checker is at the bottom. The two Model 3 B for TVHeadend are stacked above.
The ATV Checker is running on Raspbian OS using an old Raspberry Pi Model B+. For details of my ATV Checker see the following url:
The file /etc/modprobe.d/dvb.conf needs to be configured. I set the checker to adapter 7
The two copies of TV Headend are running on copies of the Ubuntu Mate operating system.
See the Raspberry Pi homepage for the Ubuntu Mate download and installation instructions.
The file /etc/modprobe.d/dvb.conf needs to be configured.
I set Adapter 7 for TV Headend.
Running within Ubuntu Mate on my Raspberry Pi 3 is a copy of TVHeadend.
Installation instructions for TVHeadend may be found at: http://kodi.wiki/view/Tvheadend
The configuration of TVHeadend may be opened using your web browser.
Due to the ending of support for Mythbuntu. I migrated to the Kodi platform.

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.
Here are example recordings for VK3RTV1 and VK3RTV2.
