In article , says... Is the AM reception as weak in the Tivoli PAL as it is in the Model One? How about the Boston Acoustics Receptor (AM Reception)? I was somewhat disappointed in the MW reception of the Recepter. It's definitely not a DX machine as it stands. They did, however, allow the internal ferrite antenna to be very easily replaced with an external antenna. I'm sure the MW reception issue is primarily due to the use of a small internal ferrite bar. Switching to an external antenna that can be easily rotated would improve reception considerably. FM reception on the Recepter is among the best I've heard. -- Jay Hello, Disclaimer: I speak for myself only, and not for Tivoli Audio, nor do I have any connection to Tivoli. I designed the Model One and the PAL electronics. IMHO a PAL will provide good reception of all but the weakest AM stations. The PAL has a 2" ferrite rod antenna which limits the sensitivity to that of radios with a comparable length antenna. On AM, size definitely matters. Both the PAL and the Model One have pretty good sensitivity, and have better than average selectivity and dynamic range. The hi-fi sound is the best part, as most owners will confirm. Mediocre AM sensitivity on the early Model Ones was substantially improved shortly after its' introduction, unfortunately not before it got a poor reputation. If you're trying to get the most distant AM stations a GE Superadio will do better with its 8 inch long antenna. Many digital radios with an internal antenna suffer from self-interference due to HF noise from the digital circuits, and this will limit sensitivity. A Receptor with a long wire or long ferrite rod external antenna should work well, although at some point the input RF stages could either be detuned or overloaded. A high Q tuned loop external antenna improves reception in almost all situations. G. Cook |
