The PCA2 uses a 455 kcs IF with an adjustable core.  I suspect I can realign this unit to take the 500 kcs IF but before I do, I'd like to have caveats from the main body.  Thanks. Cal, N6KYR/4

Two problems probably with the Panoramic PCA2. One is sweep linearity
when moved up in frequency, the other is getting the coupling right
between the input coils to compensate for the main receiver IF
selectivity and keep the front end of the panadaptor even compensated
above and below the receiver IF. In the manual, Panoramic repeats the
range is 450 to 470 and refuses to admit it might move further.

I found the manual on the BAMA mirror.
