Post Subject: Where to get custom crystal oscillators.Posted by Romy the Cat on: 8/15/2011

With the coming of the new director to WCRB (Benjamin Raw) the station, without any big hooplas and announcements of “perestroika”, kind of surreptitiously, is turning out to be a truly fine classical station. There are ton of things that they do nowadays that is very welcoming in my view, which makes the FM junkies like me immensely happy. So, with great advancement of WCRB programming and since a lot of my listening is FM programs I took some measured to beef up my FM capacity. A new antenna, a new way to tune my directional antenna to the stations to name a few, the last one that I would like to try is to switch my Rohde & Schwarz to work not from own local oscillator to quartz oscillator.

Sonically, the TU-1X with modified multiplex and modified Schwarz with own modified multiplex are not distinguishable. The reception is different matter. In my old location what different in reception was very minor (with TU-1X manually attenuated) but my new location has much more complex reception situation. The WCRB I can get as clean as the best CD with noise at the level of the station transmitters capacity. The WHRB is more complicated and I still work on it. In any case it looks like with all tricks I use the TU-1X does better job with WHRB but Schwarz truly works great with WCRB. Here is where Schwarz truly shine as I use a complex defective reception from the edge of a hill and in this case the quality of the Schwarz front and IR filtration become prominent.

Anyhow, since the Schwarz will be permanently set to get WCRB I am considering converting it to crystal oscillator. No matter how good the Schwarz internal oscillators is but crystal shall be 10 times better and thanks God the smart Germans made the provision to let the receiver to use a selection ether own local oscillator or a quartz oscillator. So, the station is 99.5MHz and the Schwarz runs 21.4MHz IM frequency. So, I need 120.9MHz serial quartz oscillator. Does anybody know a company where can I order custom frequency quartz oscillator and have no minimum order?
