R5[3]

not used in application board

R10

8.2 k  5 % 1⁄4 W carbon composition

R11

10 k  5 % 1⁄4 W carbon composition

R17

2.4 k  5 % 1⁄4 W carbon composition

R18

3.3 k  5 % 1⁄4 W carbon composition

R19

11 k  5 % 1⁄4 W carbon composition

[1] This value can be reduced when a battery is the power source.

[2] This is a 30 kHz bandwidth 455 kHz ceramic filter. All the characterization and testing are done with this

wideband filter. A more narrowband 15 kHz bandwidth 455 kHz ceramic filter that may be used as an

alternative selection is Murata CFUKG455KE4A-R0.

[3] R5 can be used to bias the oscillator transistor at a higher current for operation above 45 MHz.

Recommended value is 22 k, but should not be below 10 k.
