Re: Improving selectivity on a reciver
|
Your helicals should already be much narrower than that.?? What problem are we trying to solve?

Hello Everyone,
?
Let me first say this is an experimental improvement to see it will work.? ? I have a hamtronics reciver board that is running in the 220MHZ space.? ? ?It's one the last board produced before the owner had a fatal bicycle accident.? ??
?
I wanted to see if I could improvement the selectivity of the receiver by narrowing filters or am I look at more of a total redo of the circuit.? Like I said, I'm doing this as a experiment.?
?
I wanted to narrow it to the current 222-225 Mhz from the old 220 to 225 Mhz.? ?
?
Any suggestions would be helpful.?
?
Thanks
