Hi Guys,
Another long shot from me, and yes, again it's hardware that's EOL
and "Not recommended for new designs", but it happens to be perfect
for my needs (a 13cm Amateur Radio Beacon if anyone is remotely
interested!)
Anyhow, I have the opportunity to acquire a RFX2400. I understand the
RFX2400 has a Band Pass filter that covers 2400 and 2483. Obviously
for 2320 this is unwanted, but I understand that it "can easily be
bypassed"
I can see it on the schematic. Looking at the schematic though, it
looks like this might need to be a hardware mod ? by cutting the
tracks that go from pin 3 of U202 to the SAW Filter ? Or shorting
pins 2 and 5 of the SAW filter ?
That said, Pin 5 of U202 suggests a software method might be available.
Anyone know for sure ? And if it's software, how, especially from within
GRC ? I'd really rather not have to start butchering things if at all
possible!
Thanks and Best Regards
Iain
You'll need to modify the hardware--the RFX-2400 didn't have any
software support for filter bypass that I know of.
