LF: RE: LF Receiver

["Nick Mclean (SYD)" <Nick.Mclean@foxtel.com.au>]

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
