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 f
Hi Nick, The R75 is pretty much the receiver of choice in the LF community in the US. Works well out of the box, and excellent value for money. Cheers, Steve http://www.w3eee.com Nick Mclean (SYD) wr
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
Laurie I've been using the RF-590 for 8 years now as my primary LF/MF receiver with no problems or complaints. The 1 dB compression and 3rd distortion is on par with other 'premium' military grade re
Laurie, From among my own receivers, I find that the Cubic 3280 is a very good DSP receiver AND you can shut the AGC off. For non-DSP, the newer RACALs such as the 6830 work great and have switchable
Hello Laurie, I have used an ICOM R75 and still own a AOR AR7030. Both are excellent performers at LF. The AR7030 has top notch rf performance but the ergonomics of the AR7030 are a bit unusual. The
Sorry - I misunderstood, thought you were trying to digitally downconvert directly ! Yes, that would work quite well. In fact G4GUO did just that on 73kHz a few years ago using the 56002EVM with left

Albertoo et al - I was keeping away from having to use fast DSP and digital receiver technology for a piece of standalone signal measurement test kit to use in the field without a PC attached. 130dB
[snip] IF filtering will be a 300Hz bandwidth mechanical filter at 455kHz. Very extensive front end filtering is needed to remove the image response which sits in the MF broadcast band at 910 - 1070
This Rx is intended as much a piece of test equipment as a portable receiver. For the IF gain the Analog Devices AD603, has 0-40dB gain with a voltage control of 0-1 V, laser trimmed for 0.3dB linear
