Rob OK, I'm having trouble figuring out how to reply to each message so...thank you very much to all who replied, especially the person who pointed me to the Chinese rim manufacturing webpage (I cannot find the message now! I think the old days with a newsreader worked better than the Web version but oh well... Discussion...closed. Best regards, Rob |

So Jeff, I have a FM tuner/reception question. I have a little Pro-Ject Tuner Box: http://www.musicdirect.com/p-115288-...ner-box-s.aspx $200 Euros list price. Ouch. Data sheets from Austria: http://www.box-designs.com/main.php?prod=tunerboxs&cat=source&lang=en http://www.box-designs.com/inhalt/en/pdf/tunerboxs.pdf It has a Belling-Lee (PAL) plug on the back, and I use an F adapter. http://www.showmecables.com/product/...e-Adapter.aspx The specifications say that the tuner uses a "DIN plug". Page 2: Antenna input Connects any antenna cable with a coaxial DIN-plug / US model F-plug. So, you must have a European model that was smuggled into the USA by nefarious means. Unfortunately, the authorities do not offer rewards for such offenses, so I'll pretend to ignore the problem for now. Attaching ANY coax (whether or not connected to an antenna) via the F adapter adds a ton of hiss. That's totally wrong. Unfortunately, I can't even guess what might be the problem. Offhand, I would guess(tm) that the tuner front end (RF amplifier) is sick in some manner. However, without my pile of test equipment, I can't be sure. Even if it were true, there's not much you can do about it other than have someone with repair experience take a look at it. In other words, I have no idea what is happening. Well, one thing you can check. With a voltmeter, make sure that the 9V power supply is actually delivering 9VDC. The actual voltage isn't terribly critical. +/-10% or 15% is probably acceptable. However, if it's ridiculously low, that might be the cause of the oddity. If possible, measure it with the rated load (300ma or a 30 ohm resistor load). It sounds better with no antenna at all (although the signal is very weak) -- or the adapter plug is used with just a piece of bare copper wire sticking out the back. If I hook it up to my house antenna (I'm old school, no Comcast -- and the transmission tower is within five miles), it super-noisy. My antenna is in the attic and has UHF and VHF elements. It is not grounded. Is there some weird shielding issue? Unlikely, unless the connector, adapter coax, or antenna are shorted between the center pin and ground. If you have a handy ohmmeter, just check the connectors for such a short. I terminated the coax with a standard F plug and believe that I did it right. The same sorts of terminations are working with my TV. I don't see any obvious problems with the F to Belling-Lee adapter. There is nothing weird about the "DIN" connector. An F adapter should work without any drama: http://www.box-designs.com/inhalt/bilder/tunerboxs_2.jpg Good luck. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
