I have the following polar diagram. Is this bug fix likely to improve it, or is it only in certain circumstances?
My understanding of the blackholes around Sydney are/were approx here:
So if you were seeing the aircraft disappear from your radar screen in the area towards Canberra in the bottom right of square, then likely you will see them all the way to Canberra with the new software.
Or perhaps would a mast head amplifier kit improve things. My antenna is located on my balcony railing on the 13th floor of my apartment building.
I'd suggest its unlikely, I have bought 2 thinking the first was faulty, and I get less coverage with the pre-amp on. Although I have no proof, I think the preamp may be overloading the front end of my RB. I have 10m of low loss coax to an external antenna.
My guess is your run would be too short (like mine) for a preamp to make any positive difference.
