We won't hold Gordon to making great advances with the acquisition of? this nice tool, but bonne voyage on having the dBs and MHz's presented.? (Okay he is welcome to further solve the v3 and v4 remaining spurs that his nice circuit board design partly cures).?
Yes the kind of stuff Raj shows is very familiar and quite useful.? I suggest if one does not plan to do lots of work up at UHF, one can scrounge useful-enough hardware at hamfests/surplus that works at HF or low VHF.?
Iz - I recall (but never used myself) some HP portable spectrum analyzers that indeed contained analog demodulators that allowed it to function as a receiver.? These items can easily be home assembled - see if this or another spectrum analyzer contains an IF output, then you have a path to making it a receiver - even an SDR or a multi-SDR/analog receiver.? As for low phase noise, look carefully to see if it has a lower phase noise than even a uBITX -- it might be similar or only slightly better.? The ubitx hears just as well as my K2 -- both have nice PLL's (I have not put the ubitx to test with large adjacent signals but I imagine the ubitx to be pretty good).? yes get and analyze some real numbers before assuming its an advance over what you already possess).?
Glad to see enthusiasm for the radio art - everywhere around the world.?
