I'm not exactly the most active person on this group, being rx only at this
stage (and very shaky cw!), but I cannot resist joining in on this topic.
The RA1772/1792 receivers are arguably considerably superior to almost all
amateur grade receive systems available today, despite their age. Sure, they
need some care but the components are easily available, unlike the SMT/VLSI
based amateur gear. The RF performance in terms of dynamic range is
comparable (I concede improvements in technology, but these have only
managed to equal 30 yr old designs). The oscillator phase noise and
stability is certainly better than more recent gear and the filtering is
also better - and if the optional phase corrected filters were fitted then
one of the DSP plus points goes away. The ergonomics are definitely superior
but, ok, you do need a 19" rack! DSP filtering in the recent amateur gear
is, in any case, implemented at a very low IF (barely above audio) and
equivalent filtering, or, better, more sophisticated processing
(correlation, error detection etc) could easily be added outboard of one of
the older receivers. Since this processing would end up as something like
WOLF, ARGO, etc I don't expect you to quite agree with me ;-) I would
certainly like these rxs to be 300 euro (or less) but they are still MUCH
less than the amateur 'equivalent'and, I think, good value.

a voice outside the choir ! It's always interesting to hear opinions
dissenting from those of the others, as they can convey new information.
So what you are suggesting to me is to negotiate the price down to about
one half of what has been requested... I am sure to be able to
obtain a price reduction, as, knowing who is the seller, his first word
rarely is his last. But 50% discount seems a bit too much...
I don't need a transceiver, I have already a Kenwood TS-950SDX which I
like a lot. What I am in search of, is a dedicated receiver
for my intended useage. Will keep im mind your opinion, thanks for it.

It has already been pointed out that these Receivers are 15-20 years old and
in my opinion a RX that old is not worth more than around £200 ie Euro 300
approx, in fact £100 would be more than enough.
The specification for the RX is good but AGE is against it !!! There are
more high tech and advanced creatures about these days, with Digital
filtering etc better suited for your job.
