The previous Philips volume TV tuner generation was the UV600, introduced in 1985, using the solid one-piece Zamac frame and introducing the TDA5030 mixer-oscillator IC.. The first models used were pre-scaler-based in the high end CTV sets (2A, 2B and 3A from the Brugge fab) but gradually the bulk of the models used became VST without pre-scaler, driven by the need for lower cost in the mid ...

Nov 01, 2015 · First of all, FM is one of those modes that I have used on HF only a few dozen times in my 30+ years of being a ham - using it most often (albeit rarely) when 10 meters is open and I hear a repeater booming in, but other than that I haven't really had any reason to do so, particularly since there are no local 10 meter repeaters and local activity on "10 FM" is quite sparse.

Aug 09, 2018 · Still makes me wonder why Kenwood would make a FM Stereo generator to align tuners using dBu EMF or dBm as an output selection but yet use dBu=1uV as a reference in their own service manual. The dBu=1uV was only referenced in the manual for the Model Eleven GX which was a model from the late 70's and the other models are from the late 80's.

The tuner arrived this morning, thursday 22 september. Setting up the tuner on a windows XP computer was not difficult. The mini antenna was sufficient to receive FM channels, but much too tiny to receive DAB channels. I finally received several using a local TV antenna. TV reception was good with excellent picture and NO sound !

Alex Audio Video and Computer Service 4211 Rhode Island Ave N, New Hope, MN 55428. 763-533-5377 If you have a TV aerial and wanted to know if you could use this listen to radio or connect directly o your FM or DAB radio tuner. Read this for tips and advice. In this blog I discuss possible ways to access radio programmes via a conventional TV aerial. I have such reception and have found that inexpensive tuners like my NAD 402 and Sansui TU- 217 perform quite well, and sound great. Some of my other tuners have better DX'ing capablities, but they're really unncessary here. I have owned many excellent tuners over the past few decades including a 10B and Sequerra FM Studio. Lock-out HD and lock-in FM-stereo so that the tuner doesn't switch from one to the other. Since the HD-digital takes longer to work its way out of the broadcast station, there is a nasty silence and time-warp as the Sony tunes from one to the other and back.
