[TenTec] New radio fever

[Jim Reid]

" Leif, SM5BSZ has confirmed IC7800 +40dBm IP3 claim on Apr 
27th measurements!"

As measured at 20 kHz signal spacing;  I assume preamp OFF.

Wonder how it will do at the ARRL labs when they test the
5 and 1 kHz signal spacing?  Also,  was any feed forward
gain reduction in use,  al la the Icom license from Rohde and
Schwartz??  [See U.L.Rohde article,  QEX, Jan/Feb 2003,
specific info on page 29:  "Dual-Loop AGC" for what
such  a technique accomplishes to reach very high IP3 numbers.]

The ARRL will be sure that any dual loop, that is RF AGC feed 
back is desabled during their test,  per Ed Hare,  else the test has 
no real meaning as an apple to apple comparison.
