[TenTec] O3 wish list

[CSM(r) Gary Huber]

It may sound like heresy on this forum, but the use of an external SDR 
receiver like the Flex-1500 or any basic SDR running PowerSDR via the N4PY 
sub-RX mod provides the panadapter function without the IF port or tapping 
into the IF of older receivers. Or one MAY choose to receive the IF on the 
Eagle.

Well said and totally agree Paul.  Limited engineering resources can
be put to much better use.  If the rig mfr provides I.F. output,
they've done their job.
