I think in that regard the software plays as big a part as the hardware,
so your choice of software will possibly govern what you can or want to
do. Fortunately most are free so you can try or use several. Perhaps
fiddling with the various bits of software might give you some insight
into what you would like to achieve and the likely ability to do so.
Then spec your hardware to suit.

(hi)
Probably the most interesting use would be to see the transmitted spectrum
of stations on the band.
If I hear broad splatter, it would be nice to easily see where its coming
from and see just how broad it is, compared to other signals. Same for key
clicks.
It would be nice to look at my own signal and see how broad it is, if it is
flat topping on peaks, etc.
Looking for empty frequencies to call CQ on is not very high on my list of
needs.
Watching boring waterfalls is not high on my list either.
But you bring up an excellent point, Barry.
I don't even know what all it can do.
I would like to see a features list showing all of the uses of a
pan-adaptor.
I don't need a big explanation for each, I just would like to see a list of
things one can do with a pan-adapter.
If I understood Jim correctly, you need a pretty expensive solution in order
to be able to make accurate measurements with it. He indicated he can do
that on his K3 with Elecraft pan-adapter. That's not on the plan here for
the moment.
Thank you for the comment.

Rick, I think it would help if folks knew what precisely you want out of the
panadapter. They potentially offer lots of bells and whistles, but
many/most might not be of interest to YOU.

This topic in similar form has been covered in many different threads
here and in the other TT groups.
I want to add an external pan-adaptor to my older Eagle. My Eagle has
no 9 MHz out and also has no TMP jack on the filter board for tapping
into the IF.
WHAT I AM LOOKING FOR:
'Specific information' about how to compare the technology of the
various receiver candidates.
WHAT I AM 'NOT' LOOKING FOR:
Comments like: "I've had good luck with XYZ".
Besides being an almost useless comment, we've read those types of
comments multiple times already.
BACKGROUND:
Although my Eagle has no easy provision for 9 MHz out, it does have
the 2-jack mod which routes the transmitting antenna out the back
panel, AFTER the signals have passed through the Eagles RX BPF's. I
suppose this eliminates the need for BPFs in the External RX, but it
is probably better to have them anyway, so that I can also use the RX as a
stand-alone.
My personal interests stop at 30 MHz, but in the interest of
completeness and learning, if there are benefits in the various
technologies above that, say up to 70cm, then please share them with us
too.
It will be FAR EASIER for me to simply use the ANT OUT line on my
Eagle than trying to tap into the 9 MHz.
I'm not afraid of using a soldering iron, but the Eagle is very tiny
and my eyesight is very poor.
Unless there are some darn good arguments for an IF connection, I will
use the ANT OUT.
THE BIG QUESTION IS: JUST HOW GOOD DOES THE EXT RX NEED TO BE?
Remember, I wish to do this on a shoestring budget, but maximize my
bangs for the buck.
I have read suggestions for:
* Softrock Ensemble III
* FiFi (a German RX costing abt. $165 in kit form)
* SDR-4 (an English RX costing abt. $300)
* LP-Pan
* Fun Cube
* Watson W-SDRX1 (my own suggestion; is also available locally under
another name for $110)
IN SUMMARY:
How do I compare and evaluate these candidates?
I am interested in things like on-board technology, and ease of
implementation.
I wish to keep it simple and I have zero interest in installing Ham
Radio Deluxe or any similar over-kill product.
I do have N4PY control software for my Eagle.
Though I'm looking for a cheap solution, I am not looking for the
cheapest solution. If I can get advantages for spending an extra $50,
then I would probably do that.
Thanks in advance for technical information on this topic.
