DRS25ANXT - Electronics interference

[alphabradley]

Hi all,

I currently run a DRS25AX/4 on a Regulator 34. I had significant problems with interference with my FLIR M364C, even when mounted outside of the 12.5 degree (or thereabouts) beam angle AND 3m of distance. The interference would cause the FLIR to randomly orbit and eventually go offline. I ended up just creating a dead sweep and that resolved it.

I'm outfitting a new boat and I'm looking at moving to the DRS25ANXT solid state. Has anyone had similar experiences with the solid state radars vs. the magnetron radars? I want to solve this before I install everything and then have to undo it all and rewire the hardtop.

Thanks in advance!

One of the things that many people don't know about signal specifications is that the beam angles specify the "main concentration of energy". It is not a hard limit where there is no long any energy being transmitted. This is why when you utilized the "dead sweep/blanking sector/no transmit zone", the FLIR was no longer effected by the radar transmissions. The alternative solution would be to get more vertical separation between your radar and FLIR.
The solid state radars tend to have less spurious emissions but you will still want to follow the same set of rules. People often say that solid state is safer or causes less problems when blasting other devices because they are lower power. While it is true that they have a lower peak power output, they end up with more power on target than a magnetron because they are always transmitting whereas magnetron radars pulse on and off.
