Test Circuits
NOTES:
4. All resistance values are in ohms.
5. L tunes with 100pF (C) at 10.7MHz.
6. Q0 (unloaded) ≅ 75 (G.I. Automatic Mfg. Div. EX22741 or equivalent)
NOTES:
7. All resistance values are in ohms.
8. T PRI. - Q0 (unloaded) ≅ 75 (tunes with 100pF (C1) 20↑ of 34e on
7/
32” dia. form).
9. SEC. - Q0 (unloaded) ≅ 75 (tunes with 100pF (C2) 20↑ of 34e on
7/
32” dia. form).
10. kQ (percent of critical coupling)
≅ 70%.
(Adjusted for coil voltage VC) = 150mV.
Above values permit proper operation of mute (squelch) circuit
“E” type slugs, spacing 4mm.
