For the reason explained by Floyd, it seems to me that today, inclusion of a 
panadapter into a transceiver is not a very good use of a company's design 
resources.  The inclusion of a simple 8-9 MHz buffered IF port opens up a 
whole new world to the operating experience that can never be completely 
duplicated with internal band scopes.  Of course, that assumes a 
mid-frequency IF is available in the design that precludes such an option 
with traditional up-conversion designs.  Ten tec was smart to add an IF port 
to the Eagle.  That one low-cost feature alone separates the Eagle from the 
Kenwood TS-590 by a long shot.

In 2005, I purchased an Icom IC-7800.  For the two years, my thought was 
that any manufacturer who could not, or would not, include an internal 
panadapter would soon face extinction.  I held that view until something 
quite abrupt occurred.  I experimented with an SDR-IQ on the IF port of an 
Elecraft K3.  After witnessing the panoramic detail, waterfall display 
choices, secondary receivers (through SDR-IQ), there was no turning back. 
Suddenly, I viewed internal panadapters as a millstone around the necks of 
manufacturers.   None of the present manufacturers have the resources to 
provide the pan ability and control utility provided by SDR-IQ, SpectraVue, 
LP-PAN, PowerSDR-IF, etc., nor should they.   Look at the display provided 
by Yaesu with their FTdx-5000 product.  Frankly, it's a panadpater in name 
only.

Manufacturers only need to give us a high-quality IF port and a means for 
rig control.  The rest of the panadapter and control functions can be better 
managed by folks like Carl, N4PY, Moe, AE4JY, and Scott, WU2X.  Despite past 
moans from Ten Tec users, I think that in the end, Ten Tec was right to 
delay inclusion of an internal high-performance panadapter into the O2.  At 
some point, perhaps Ten Tec may want to market an external panadapter 
similar to the Elecraft P3, where that device could be used for more than 
one Ten Tec transceiver.  Even so, it's doubtful that the device could 
approach the low cost and high performance provided by a small netbook PC 
and SDR-IQ or Softrock receiver.
