1.38MHz - 919kHz = 461kHz close to 465kHz. Problem here is the 1.38MHz which can be 1.385MHz which results in 466kHz .... Everycircuit precision is just 3digits.

Hurz, yes, there is this little discrepancy due to the precision of the frequency setting and display in EC. However, if you observe the frequency of the IF oscillations on the scope, you will see that it is close to 465 kHz. This is because you can control the heterodyne frequency by adjusting its inductance with a higher precision than what is used and diplayed by EC for the frequencies greater than 1 MHz.
