I would expect the first of those options to be the case only in some bizarre parallel universe :-) The second depends on each of our personal definitions of "inexpensive". I'd expect it to be on th
"Receiver" is probably just a bad choice of words on my part. The 781 had a dedicated module that did nothing but sweep, with a signal pick-off early in the IF chain, so a receiver in the loose sens
Interesting. I use the software only remotely (from a computer in my office, outside the radio room) so I haven't watched the radio at the same time I was tuning from the PC. Is it because I can spi
I'm not quite sure what you mean, but of course it moves when you tune. It doesn't move WHILE you tune, at "normal" tuning dial rates using the knob. The minute you stop, or even just hesitate, the
Very noisy band conditions here tonight, with storm noise in the area -- lousy band conditions overall, and propogation seemed to be off, with many of the usual big gun signals not up to par. I set o
It's true that the sweep may not meet everyone's operating needs. It's better than it has been previously, and is certainly more than adequate for my use. As I indicated in a post last night, I foun
I did redo the SNR tests on 20 today. The result there with a much better band noise profile to work with was on the order of 20dB improvement. I ran most of the tests at 1Khz BW. I'm not trying to
After all of the gnashing of teeth about the sweep not updating during tuning and whether it's useful or not, etc. etc., I decided to try and figure out when it worked, and when it didn't. Ok, it you
That's my normal setting, too. But now at least I know's there a setting that will generally keep the sweep updating. I was probably the last one figure to figure it out, though :-) Grant/NQ5T
I seriously doubt that V1 was bounds ahead of V2 in SNR improvement. I doubt it was actually any better at all. That's a guess, of course, because I don't have a v1 radio to measure any more. V2 is
Played around with the NB a bit this morning, with an S9+20 relatively constant noise level that had an unusually high line noise component on 75M. (Fortunately, the line noise has faded as the day h
For those that have been asking, the firmware revision history file for the II has been updated on rfsquared. The only entry is fix of the "sticking TX-OUT" bug. Grant/NQ5T
Except for the fact that I was talking about the NB and not NR :-) To your point, I've come to the conclusion that while you're generally correct, NR does add to SNR even at very narrow bandwidths.
Yes, and I checked it 10 times, because that's an easy mistake to make. Oh, well :-) Perhaps "on the order of something greater than zero" would have been a more correct statement. In any case, ther
Yes, it was off. No, it was just easier to get to. So this morning, I dug into my storage closet, and pulled another meter. It isn't a 339A but it is a true RMS meter I redid the measurement, this t
You're correct. I had to dig around and find my spec sheet. Live and learn It is RMS, calibrated to a sine wave. I understand that, and appreciate it. The fact remains, there does appear to be furth
What I find most curious is that everyone who feels the elephant feels something so totally different. It's what makes me think the variety of opinions on what floats our respective boats (or not) i
Bill ... I will have a proper meter on the way later this week, and a couple of other goodies. I do intend to redo the test measurements, hopefully will have them published here within the next coup
All this talk about audio "chips" and tiny little speakers, makes me long for the days when real radios had push-pull 6V6's and "phono" positions on the mode switch :-) Failing that the Sounds Sweet
