Back to the topic of my Jonell radio then

.I have tried the test suggested by Oldtimer and got confusing resultsWith Jonell set to 198 on the dial and a long aerial,I did not find a oscillation around 663Khz on my Superdrug Dm 906 with frequency display.but I did get 2 points of oscillation at 673 when jonell set turned to 1400 and 1590m(~212 and 188khz).Does this indicate that If alignment is out? I have not touched the IF cans as don't have a sig. gen.
I repeated test with Jonell on 909 on MW and a similar effect.Only oscillate at 2 points slightly away from tuned station.
