Philco 60 - Problem with Short Wave/Police Band
#17

I see I never did report back with the correct number of turns in the 60 oscillator coil primary - my apologies.

I'll give details on both coils while I'm at it.

Model 60 Antenna Coil

Primary (outer) winding - 4 turns, CW, bottom to top, 38 gauge
Secondary winding (on the coil form) - All CW, bottom to top. 25 turns from beginning (lug 1) to lug 3. 129 turns from lug 3 to lug 2. 20 turns from lug 2 to lug 5. 32 gauge works well for this winding.

There is also a separate winding inside the coil form, mounted at the top. It is approximately 250 turns, 38 gauge.

Model 60 Oscillator Coil

Primary (outer) winding - 18 turns, CCW, 38 gauge, bottom to top, lug 3 to lug 2
Secondary winding (on the coil form) - All CW, bottom to top. 15 turns, lug 1 to lug 4. 90 turns, lug 4 to lug 5. 22 turns, lug 5 to lug 6 (on top). 32 gauge is OK for the secondary.

To determine which lug is lug 1, 2, 3, etc., hold the coil by the large mounting lug and count the small lugs clockwise from left to right.

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
