What's a panadapter?

[wb2srf]

Hi Peter,

A Panadaptor gets its name from an abbreviation of  Panoramic receiver
display adaptor.

Its purpose is to allow the radio operator to see what signals are within
the band of frequencies that he is operating.

For example instead of manually tuning or scanning the receiver to find a
station to contact. The Panadaptor will show all of  signals within a few
hundred KiloHertz. Some adaptors have the provision for a Mouse like
control where you can move the cursor over a signals peak and the click
the Mouse, the receiver will be automatically tuned to the frequency.

It also provides valuable information on whether there are any strong
adjacent channel signals that you may want to avoid to have some control
over interference.

So a Panadaptor could be compared to a spectrum analyzer?

IIRC, Panadapter is (or was) a trademarked name.  Certainly it's come
pretty close to being generic, but I suspect that why the display in
current radios is called a "bandscope".

Hi Paul,

You have a very good point.

Band Scope by definition makes a lot more sense to relate to its purpose.

If anyone has experience, they will get a good chuckle.  The AN/ALR 20
on the B52 aircraft was developed in the 60s, and it sounds like it has
been recently replaced.  Now THAT was a panoramic display.

A quick search of the US trademark database (www.uspto.gov) says it's
available. It's mentioned as a type of equipment sold by Squires-Sanders in
a 1963 filing for their logo, but it's not named as a trademark by anyone I
could find.

"Bandscope" is similarly unclaimed.

IANAL, but both would probably be dismissed for being generic at this point.

The original Panadaptors, as I recall, in the WW2 era, worked in the
receiver IF, as RF spectrum analysis was but a dream when it came to
affordable circuitry.

I think a Panadapter is an accessory for your rig so it can double as a
cook stove when you are out in the field.
