Re: [IRCA] [NRC-AM] Building a "state of the art" MW DX station

[Nick Hall-Patch <nhp@xxxxxxxx>]

Hi Les,

There was a discussion concerning the SDR-IQ vs. the Perseus on the 
Perseus Yahoo group around the end of November; look in the group 
archives for details.    The Perseus software seems to be rather 
static, while the SDR-Radio software for RFSpace radios keeps on 
being developed, and even the simpler RFSpace Spectravue software 
keeps improving in fits and starts (remember that software is 
important in a "software defined radio").  However, I don't think 
anyone would disagree that the Perseus hardware is more 
crunchproof  than the SDR-IQ, in addition to the Perseus' greater 
bandwidth.  More recent RFSpace radios are more comparable to the 
Perseus, but they are pricier.  For some peculiar reason, they come 
complete with electrically noisy power supplies along with the higher price.

As for antennas, the broadband Wellbrook loops do seem to be quite 
resistant to local noise.  I've used the ALA100 with quite a lot of 
success in electrically noisy hotel rooms, suspended in a window, and 
driving both conventially tuned radios and SDRs.   Tacking the loop 
onto your fence (the loops receive well close to the ground) will 
likely give quite good results.   Main problem is that loops do have 
a null.  Can you do two loops at right angles to each other (maybe 
after verifying their lower noise level at your site before springing 
for the second one), and switching between them, or even phasing them together?

best wishes,

Nick
