[TenTec] Crystal Differences between Omni 546B and 546C

[Kenneth Stringham]

Hi,

I, recently, purchased a 4Mhz crystal to put my 546C
on 17mtrs, but this crystal does not seem to
oscillate. Is there a difference between the
oscillators in 546B and 546C? I bought a crystal for
12mtrs at the same time. This crystal works just fine.
My concern is that the choke and feedback capacitors
are sufficiently different to prevent this circuit
from oscillating at 4Mhz. It does oscillate in a
sufficient manner with the 5.8Mhz crystal used in
160mtr circuity.
