[Premium-Rx] better receivers.

[Carcia, Francis A HS]

hi,
Things change so fast that there is no profit in supporting old hardware. It
sells 
cheap in the first place. I would like the radio all in one box with an
ability to down load different software or remote control. I found this
problem when I bought a MOT 
DSP eval board to play with a DSP demodulator. Two years later it is off MOT
radar.
It was a cool project and learning tool. Another option is a radio that has
a standard bus that would accept new features like a sound card or video
interface. Say an Industrial Tempest computer with a radio front panel.
Split the case in two sections.
one side for RF and the other for the pikuter. Put a nice display on the
front panel
with a key pad volume control and a nice opto encoder off a NCI machine with
nice
knobs. My homebrew RX has modules that can be upgraded one at a time.   fc

Make that a third.

I've learned the hard way that an instrument dependent upon PC control is 
soon obsolete.  The special card (ISA, PCI, etc) that goes in the PC and 
will only talk with certain versions of Windows will render the whole 
instrument useless when it craps out, or you can't buy PCs with <insert bus 
standard here>, or you can't buy that version of Windows anymore, etc.  And 
good luck getting any assistance from the manufacturer.  They plan on 
supporting equipment for a year or two tops.  They can't even purchase 
replacement parts in many cases.

We've had a thread on amfone.net on this subject:

In my professional life, I still use receivers that were designed and made 
over 30 years ago, while much newer ones are essentially useless due to the 
proprietary A/D board dying, or the special laptop controller crapping out, 
etc.  Newer/faster/better for a WHILE, to be sure - but I find it 
interesting that receivers getting on 70 years old such as the HRO are 
really yet to be obsolete.  They are still eminently usable, they are easily

repairable, and they really aren't THAT far behind the most modern DSP pie 
pan box.  No way could I justify spending $500-1000 that will be essentially

useless in about 5 years - and even if not useless, it would be hopelessly 
overtaken by even newer/faster/better radios.

I learned to hate PC and mouse control of receivers after using the 
Rockwell/Collins 95S controller program.  Wonderful radio if they'd put a 
front panel on it.
