I was looking at the blinky board receive section and I had a question. It has a shunt resistor for bleeding charge off the antenna and a series capacitor on the antenna input with a note that the shunt resistor will add some noise. I was wondering why it didn't have a small 2nd order shunt first filter there instead. Since it's shunt first, the inductor will bleed off any charge from the antenna. And it would provide a little filtration on the input, which would seem good to me.
Just more curious than anything.
