How deep can one go with FM signal analysis? I'm interested in what instruments people are using to analyze their FM signals. Here in Westchester County just north of New York City we have a few good stations. I use a Winegard FM antenna and rotator ...

You would not need any “special” A/D converters, as I did impose any demeaned to “quality”. All you that you need to have a more or less reasonable tuner, a good antenna, strong reception and an ability to write it up at 24/44 or 24/88/ Also it is ne...

Well Romy:A quick calculation shows that the angle of elevation is 1.24310 degrees (i.e tan inv of (949-160)/36360). At a horizontal distance of 2000ft from the antenna, this angle of elevation results in an overall height above sea level of 203ft (i...

Yep, you were close. The listening room is looking right to the conservation land, in the middle of which there was the original Battle Road. So, that proverbial “shot that was heard around the world” was fired some in the backyard of that house....

[quote user="N-set"] Gdansk, Poland
I thought it makes no sense to install a more elaborate and
powerful antenna just to later add even more attenuation? Or am I missing
something? [/quote]The whole idea of directional antenna is the that it giv...

[quote user="Romy the Cat"] As now the Rohde & Schwarz + T-85 sound just wonderful and I would not look for other Multiplex Decoders with exception of a future idea to built one even better (with L de-emphasize) INSEDE of the Rohde & Sc...

So, don't hold back... did you like it???I, too, love the great outdoor venues, like the Hollywood Bowl and the old Greek Theater, which probably do not have bad seats (or at least they did not before DSP...). I have also seen/heard ...

Is the "ground plane" in this case literally a sheet of copper that you run all the grounds to? If so, this may be overkill on the one hand and an antenna/noise magnet/generator on the other hand, and/or it may well make for ground loops. It is u...

Keeping harassing different people bout the most interesting options for multiplex decoder for my Rohde & Schwarz EU-6201 I was wondering if it makes sense to me to use the Rohde. It is a very good tuner but it is not necessary result in better s...

Looking at the schemo, I guess sometimes there are actually good reasons why certain solutions to common problems are popular. Meaning, I ass-u-me you have the noise consistently down to acceptable levels with the split-type L, etc., and no more run...

So I decided to try some of the mods mentioned to my semi-recent 834p w/ MC step-ups. It all started with C1 and C7...but then i got into RIAA, upgraded diodes and filter caps. Well, everything should be just stellar on paper but...now I have a hum t...

It took me a while to figure out an effective grounding scheme for the system, and it has taken me until today to finally get around to lifting the K&K's chassis ground at the wall.The unit is still grounded to the whole system dedicate...

A lot I know, I gave up on serious FM decades ago because I just haven't had acceptable access to good programming or broadcasting. Still, I remember the fiddling I used to do trying to polish the gain/selectivity equation. When and how attenuation i...
|

Of course you can do it all by ear, and I found that there were times when "my ears disagreed with the meter". As you note, signal strength and "quality" also relate to "mode" (such as Multipath), and not only broadcasts but also tuners vary as to wh...

Cat, Thank you for your time trying to help.I'm not engaged to my Accuphase though I do care about it.I read your comment on the ASP antenna and went to their site. In their tuner section for alignment and repairs they have amoung other tuners a ...

It is truly perfect evening here, in the Romy the Cat’s castle. The weather today in Boston is phenomenal, temperature just spot on, with no wind of humidity. I woke up just 15 minutes before the BSO broadcast, warmed up the Milqs, Schwarz and Lavry....

Jp, I think what you do is wrong. The ferrites that you use on the picture are worthless as they will not be having much coupling between the cable and ferrite cores. You need to block entry to Sansui for HF noise. The noise might enter via power cab...
|
|
[quote user="Romy the Cat"] Still the key is to treat the cables, all cables that go into tuner and into the processors. Do not forget that you have a perfect loop: tuner goes to preamp, as in the same time tuner goes to A/D-DAW-D/A- preamp. So, you...

I have to say, that I genially like the new 99.5. I do not have as perfect reception as I had with 97.9 with absolutely clear, no noise background. Still, thankfully the compression of the new 99.5 is very low and last night and today live broadcasts...

which hasn't been serviced by Stereo Surgeon, hence the 75R FM input has the normal gain. Right?I still don't know what's the FA7 for. Test signal to align the tuner? Lower gain for amplified antennas? I'll be very thankful if you could give some inf...

Yep, the TU-X1 is just wonderful. Find someone to align it, have a good antenna, good attenuator (it is hard to use it without one) and headphones to set the attenuator right – it is all that might ever need from FM. BTW, are you planning to record a...

I did some listening of the station that reportedly has very high quality of HD Radio and I did not like the result at all. I sound like a normal stream of MP3 file, not particularly high rate of MP3. My WGHB station do feed the HD1 and HD2 with very...

I think this has not typically been used for FM, but it is my understanding that some FM stations used to use something like this to monitor their own broadcasts.Who knows how it has changed over the years, with digital, satellite and cable broadcast...

There is a sort of "spool" or "drum" for cable "slack" that used to be run by a fool-proof rack-and-pinion gear, along with the mast; but, times being what they are, it is probably a very foolish "digitally controlled" separate motor assembly now. S...

[quote user="The Cat"]Nope, I had it floated and grounded and practically have seen no difference[/quote]Yes, I would suspect this in most installations. I guess my concern is for the rare and unusual. A floating speaker might be able to ...

The quoted subject of this
post describes the sound of this beast very well. Some commentary about your
post.
If you do have good stations
in your region worth listening then you can do better than simple 167cm
straight one. Better antenna, pr...

Well, I do not know if it was lightning but what else would it be. I did blame Amy with her hair and her curly machine and I did blame out little Koshkas for running around house like crazy and generating static perhaps. I even blamed the cleaning la...

Romy,Try wrapping a copper wire around a power cable, then "inject" it into the power line through an isolation transformer. The wrapping only to help defeat the antenna event of other signal sources that only have one vector.et all,For cables, the m...

It was as a year with a 2 major of audio events: New listening room, New Midbass horns, New ULF channel. It took almost 6 months to get any more or less reasonable sound in my new listening room, not that I was working so long on the room but rather ...
