Subject: LF: RE: LF Receiver
Hi all,
Do many people on the list use an Icom
IC-R75?
It's specs read ok to my way of looking, AGC fast, slow
or off. Attenuator. 2 level pre amp. Dynamic range and frequency range seem
good. Room for 2 optional filters.
I don't see a spec for frequency stability - does anyone
have any comments.

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
