Subject: [IRCA] Modern Ham Transceivers
Vs. Drake R8B
I'm curious if anyone on the list(s) has had a chance to test
the modern
DSP driven rigs such as the Icom 756 ProIII, Icom 7800, Icom 746
Pro,
Ten Tec Orion, etc. for broadcast band DXing?
Modern amateur
transceiver design is being driven by receiver
development...with
the
primary design criteria being enhanced performance during contest
and DXing
conditions. Namely, the ability to detect a very weak signal
nearby a very
strong signal. Third order intercept points, etc.
These transceivers
now incorporate advanced roofing filters, DSP
engines, and variable IF
bandwidths that should make them superior for
our purposes of BCB DXing as
well.
I keep hoping that we'll soon see these improvements introduced
in
a receive only box...but lacking that, I can imagine that many
DX'ers
might be tempted to purchase an Icom 746 Pro at
around $1,500 as opposed to
the much older technology in
a Drake R8B at nearly $2,000.
All but
the Icom 7800 lack synch AM, but that feature rarely helps
with weak DX
anyway...and the greater capability in terms
of IF-DSP would seem to more
than make up for it.
Very interested in comments on this
topic.
