| IC-756PRO
- HF/6m Base Transceiver
SPECIFICATIONS FROM ICOM |
 Newly
designed HF and 6 meter base transceiver, with 32-bit
floating point DSP Digital IF filter w/ 41 selectable
bandwidths, microphone equalizer, manual notch function,
TFT 5" color LCD, digital twin pass band tuning (PBT),
all mode, including PSK31, and much more. Click on the

The Greatest Thing to
Hit HF Since 
The new IC-756PRO sets a new standard in ham radio
design and communications. At the heart of the 'PRO is a
new, 32-bit floating point DSP. Older 16-bit fixed point
DSP units limited the performance of earlier rigs. Not on
the 'PRO. |
The DX Advantage You've Always
Wanted
The 144 dB dynamic range of 32-bit floating point technology blows
away the old 16-bit technology. If your ear had that range, you
could still hear a whisper while standing next to a jet engine.
With the IC-756PRO, you may not get the full theoretical
performance, but you will get amazingly clear, crisp reception and
almost no background noise.
You Will Never Buy Another
Filter
The IC-756PRO features 41 built-in, front panel selectable IF
bandwidths made possible by DSP filtering. No additional filters
or high stability crystal oscillators are available or needed. Our
filters are the sharpest - more selective than any crystal or
mechanical filters. The selectivity lets you pull out weak signals
like never before.
IC-756PRO: The exclusive rig
of Clipperton Island-FO0AAA, Bhutan-A52A, and Kingman Reef-KH5K
DX'peditions.
Three major DX'peditions. Three remote locations. The radios?
IC-756PROs. The unrivaled processing speed of a 32-bit floating
point DSP provides crisp, clear reception with virtually no
background noise. 41 built-in filters - front panel selectable for
your convenience - let you pull out weak signals like never
before. Many other features including Dual Watch, Memory Keyer,
and real time Spectrum Scope make this rig a contester's dream.
Just ask the guys who actually used them - several members were
were so impressed with the PRO's performance that they now have
IC-756PROs in their own shacks.
New, optional PS-125 power supply.
