Today I changed the SAW filter on my Lawmate 1.2GHz receiver.
The lawmate receiver is nice and compact…
The underside of the pcb.
The topside. Notice the 90° pin-header solution.
Desolder the case.
Desolder the pin-headers.
The old filter. F480-2.
New narrow band filter D480A
The whole modification took about 30 minutes.
Here is a link to my guide on changing SAW filters in receivers.
I have one original lawmate receiver and one modified now. I’m going to compare them with similar antennas on my diversity switch and see which one performs the best.
will this work on 2.4ghz ?
Thanks
