Test Circuits

NOTES:

3. All resistance values are in ohms.

4. L tunes with 100pF (C) at 10.7MHz. Q0 (unloaded) ≅ 75 (TOKO No.

KACS K586HM or equivalent).

5. C = 0.01

µF for 50µs deemphasis (Europe).

C = 0.015

µF for 75µs deemphasis (USA).

TUNED DETECTOR COIL

NOTES:

6. All resistance values are in ohms.

7. T: PRI. - Q0 (unloaded) ≅ 75 (tunes with 100pF (C1) 20↑ of 34e on

7/

32” dia. form. SEC. - Q0 (unloaded) ≅ 75 (tunes with 100pF (C2)

20

↑ of 34e on 7/32” dia. form. kQ (percent of critical coupling) ≅

70% (Adjusted for coil voltage (VC) = 150mV).

8. Above values permit proper operation of mute (squelch) circuit

“E” type slugs, spacing 4mm.

9. C = 0.01

µF for 50µs deemphasis (Europe) C = 0.015µF for 75µs

deemphasis (USA).
