Is there any difference in the receive quality of a HF transceiver rig
versus a dedicated sw receiver. the only direct comparision i can think of,
which may be a bad example, is the IC-781 vs. the IC-R9000. Thanks for the
input.

I have seen that link some time back.
Not sure if the author mentioned it or not but the PRO II ( I own one) is
deaf on LF. I measured MDS at -95dBm at 137 KHz- my band of interest. Now
using a Palomar LF--80M converter. In this combination, the MDS is -129
dBm.
Icom places a -10dB pad and an LPF in the line below 1.6MHz. Believe the PRO
and PRO III are the same topology.

Conditions were decent last night, not great. With the Palomar in line,
South American and Puerto Rican NDB's were rolling in.

Some things that comes to mind is synchronous detection and RDS readouts are
usually not features of transceivers.

Yes, this is true, but several owners of the Icom 756 series have reversed
this and now get superb reception on the LW and MW segment.
As a MW DXer I am getting excellent reception on the Icom RF-756 PRO III
below 1600 Khz, having reversed the attenuation on MW.

Walter Kurtz could also have a look at the Icom 746 Pro, a really useful
transceiver with a great receive section at a good price.
See Bjarne Mjelde's review of that also on the http://www.dxing.info
website.
There's also a discussion there on doing the MW mod to regain full
sensitivity on the MW/LW segment.

A year on, I love the 756 PRO III as it's is a serious DXer in the wee hours
of the morning, but I do miss the Drake R8B for it's outstanding synchronous
detector for listening to AM broadcasts during the day.
I think the 756 is a better bet and better value for money than the Ten Tec
RX340 as a receiver.
