Greetings again to all readers!
I am happy to report that, as of this morning, the 'RF Box' from the Brisbane VHF Group's VK4RBB beacon has been reinstated, and that all licensed output frequencies are now back on air.
Finding what was wrong with the Elcom synth has not been conclusive - it may be that a slide-on connection to it could have not been making reliable contact - so it will be a waiting game to see if the 24 GHz transmission stays 'up' as the weeks go by.
Some other work has also been effected to improve the shielding around the liquid crystal display so that the LCD should be more immune to RF interference. Again, time will tell.....
Cheers and 73,
