Fw: [Premium-Rx] Ideal Replacement for Icom R9000

[refmon]

Hi,

Lots of cool ideas, to be sure--I really like the dual rx's with the diversity slaving built in.  However, I find that features not directly related to reception tend to dilute the receiver--that is, the receiver as a product will begin to suffer as the manufacturer (or buying public) tries to stuff more gadgets in there.  Such stuff as decoders and TV demods are best executed in purpose-built form.  As an ex R9000 owner, I never, ever, found any real use for the ASCII screen and TV viewer-I just used a TV.
'
To make this receiver affordable for the listeners and profitable for the manuafacturer, the manufacturer should look to reduce their receiver lines (and various transceiver lines) to levels of commonality---NOT reinvent the wheel for each model.  Use the same processors, synthesizers, etc.  The really high-coolness receivers would be optioned sub-models of high end manually operated receivers...not every receiver would have all the doodads

You might add to your wish list:

reasonably fast processor so the receiver does not bog down PC programs
PC-style kybd/mouse interface with rx's processor for initial and ongoing configuration
EMI-hardenened chassis penetrations for keypads, displays, and external connections (also known as shielding)
external reference selectable to 1, 5, or 10MHz
meaningfully variable tuning steps--perhaps % of bandwidth AND selected discrete step
real remote control system--pro connector(s), full implementation (including squelch and audio level read/set)
proper cooling and/or ventilation
some facility for GPS-slaved ref & time clock--clock time can be stamped on remote status reads over the remote system...useful for logging
noise threshold riding squelch/raw signal strength squelch
buffer-memoried audio on SSB so squelch does not up-cut first syllable of speech
plain old every day AGC or hang AGC with programmable (true counter time) attack and decay TC's
adaptive noise blanker done in DSP - true analysis of prevailing noise vs signal
all demodulation modes and bandwidths available at all frequencies-even if the selection is "illegal"
multiple IF frequency outputs and/or programmable frequency per memory channel...for example:  freq's of 10KHz, 100KHz, 10.7MHz,  21.4MHz, 160MHz-probably others
optional UHF/EHF detachable tuning head for remoting to/near antenna 
possible tie-in of logic and algorithms for scan/sweep, noise floor, noise blanker, squelch level aimed at faster scan/sweeps with fewer false stops
"S" meter in microvolts OR dbm...assume 50 ohms, and it's a simple conversion

a real control package available from manufacturer from day 1--not the stripped-down, half functional, more grief than it's worth stuff that's been available to date (not referring to aftermarket sources)

direct protocol interface between receiver and popular printers AND standard database file layouts on PC or MAC

I don't have all the answers on how some of this would be implemented, but I do know it can be done for peanuts vs the manufacturer going with the closed system approach.

regards

  The dream receiver, in my opinion would contain the following:

  --Same layout and reception features as the 7800, including 7" Scope with increased bandwidth (to 500 kHz)
  --Wide Range Auto Tuner, designed to work on 1.0 to 30 MHz continuous (4:1 balun on rear)
  --Filter bandwidths from 50Hz--16 kHz for HF; 6 KHz--150 kHz for 30-3000 MHz
  --Continuous coverage from .05-3000 MHz
  --Two Receivers with Diversity reception possible with one knob
  --AM Synchronous Detection 
  --ISB
  --Digital Mode Decoding (incl PSK, FSK, FAX, SSTV, ATV, and the other digital modes)
  --DRM capable
  --Stereo Decoding capability (AM/FM)
  --Screen capable of TV viewing with TV decoder built-in
  --Trunk Tracking capability
  --Digital Decoding for 9600 baud
  --S Meter in microvolts
  --Firmware upgradeable
  --Inverted Voice Descrambler
  --multiple roofing filters

  What more?  This is your chance to dream!  From a technical standpoint, this is all possible in one box.  Pricepoint about $9K.  There is a niche market for this, plus the government would certainly consider it.  Your thoughts?
