Lawrence,
I'm wondering , was the RA1792, not suited to
the 'job' or is it that is failed, your looking to replace it ?
,
Have you run the self test ? , I use the exciter
MA1723, which by the look of it is very much the same , Ive had quite a
few problems with component's, but to date, have managed to get it
back working with the help of the 'bite' a dvm and rf voltmeter
In terms of price and performance , it may even be
feasable to buy a working set from e-bay and sell the original as non working,
especially if the lcd's are in good condition , you may only end up
£100 down , a lot less than the set's youve listed ?

Subject: LF: LF Receiver
Many thanks to those who responded to my mail on the subject of
receivers for LF/QRSS.
and my problems with my 1792.
Paul Hendrik for
the URL re circuits Tracey Gardner for the e'bay lead, and Warren for
suggestions
re alternative Rx's.
The lack of AGC OFF on DSP receivers
is a worrying trend as Andy says.
So I have been looking around!
I have
flirted with the possibility of the Harris 590 or the Collins 2050, both
have excellent specs and are non DSP, they look good,but do I want to take on
another servicability problem, and they are not cheap.
The Ten Tec RX340
also excellent spec. but its DSP and no AGC off.
The AOR 7030 is non DSP
and the spec is good but operationally it is very daunting,and it won't tune
in 1Hz steps and it BFO offset has only 33 steps. I am concerned about setting
it up for ARGO etc.Any comments Alan? also I guess its coming to the end of
its production.
So that leaves SDR receivers like the Perseus, thanks
Johan, but these are digital, can the AGC be turned off? and another problem
if my computer sound card is tied up processing I/Q signals can
it also do the FFT analysis ? at the same time. Perhaps Andy can
help?
So I am still looking
