The repeater will return using digital ATV to reduce the bandwidth occupied. The parameters have not been finalised but will most likely be 4MS/s, FEC 3/4, with MPEG-2 encoding on 1308MHz. Test transmissions will be run from a temporary mast until the weather improves in the Spring and then the main tower can be brought down and the DATV antennas installed at 20m AGL.
Progress to date is good; the logic has been renovated and updated by Bill G3RMX, a Comag receiver has been found and the transmitter, comprising of two modules funded by G4YTV and made by Bert PE1RKI is on test. An Alford Slot has been donated by Ken G8VDP and is being worked on and the original filter and a new duplex filter have been tuned up.
A dual band beam for 2m and 70cm will be installed with a Minitioune for inputs on those bands in the future with 333kS/s or similar RBDATV signals.
Good luck with the Alford Slot too. I hope you can tune it for your desired frequencies. If you learn anything, please Educate me
You might find these 2 test videos interesting on my home made 1/2 sized Alford Slots for Mobile use.
I use 2 on separate Mag Mounts on the roof of my car mobile.
Hope this is useful de. Ken G8VDP
