[Elecraft] Noise Generator...idea.

[Dave]

Roland

Peaking band pass filters with a noise generator is not a good idea, as
others have said it is all too easy to peak them on the wrong frequency.
While this may be unlikely, a proper signal generator (even another
transceiver into a dummy load with a low power carrier) is the better
equipment to use. There are some quite servicable signal generators on the
second hand market for very little money, even if they date from the 1960
era, provided they are of commercial grade (the Marconi TF995 comes to
mind), they are more than adequate to align a K1 or K2.

For aligning the IF filters and BFO of an Elecraft rig, a very basic two
transistor noise source is more than adequate. Mine is not even in a box,
has a fixed output and is switched on by connecting the battery "snaps" to a
MN1604 battery.
