Terry's initial "cunning" plan ... "is to have two user input frequencies and an additional shack camera input allowing a total of 3 persons to be on the same screen at the same time via a real time colour quad processor. Stations accessing the repeater will transmit their inter-carrier sound on 6Mhz and be able to control the repeater using a second sound carrier on 6.5Mhz with CTCSS tones. If only 1 user is on the input their re-transmitted picture will be full screen. If a second user accesses the second receiver input the transmitted screen will be split into 4 quadrants. The display will show the two users in opposite corners with the remaining two corners showing a test card and an information page respectively. Should the Sysop namely G1LPS wish to join in via the shack camera the information page will disappear being replaced by the shack camera image. Leaving a test card and 3 users on the screen to chat away. The test card could in the future be replaced with another receive input on 13cms or another band as licensing permits."
