![]() Today’s DSP chips are usually closely matched to the length of the whip antenna on the radio. Therefore, if you see a test where the radios and their antennas remain stationary beware…the results may be misleading. Of course, this does not always happen but it occurs often enough that it must be checked on every station in order for comparisons to be valid. But swap their positions and that signal does not follow the radio that had it first…it may stay in that location, now being received by the other radio. In many cases, with two radios side by side I will receive a given station on one radio but not the other. When comparing two FM portables it is absolutely crucial that for every test signal you move the radio into different positions and aim its antenna in every direction to maximize reception. One of the problems concerns how critical radio placement and antenna positioning can be. – many vintage radios have FM which is relatively sensitive but not as selective as the best of today’s FM tuners.Ĭomparing portable radios for FM performance is slightly different than for AM or SW. This means that, unlike the AM Mega Shootout results, many of today’s FM portables rate Five and Four Stars, which is not surprising when you realize many of then are a built on the same chips. One, Two and Three Star radios generally are older or much less expensive sets. On FM, these modern radios are often phenomenal, with excellent sensitivity, quieting curve, selectivity and capture ratio and excellent unit to unit consistency without many of the variables of critical alignment. As DSP technology has matured AM and SW performance has improved. (On AM DSP has had a rockier track record, where a few radios have been truly outstanding on AM but many have been less good than their pre-DSP counterparts. DSP has generally benefited FM reception dramatically, raising the bar in portable FM performance, such that even some of today’s relatively inexpensive portables outperform many FM portables of any price and even some component FM tuners from just a few years ago. ![]() Once done, click Ok and you’ll see the XnRetro icon from the Unity Dash home.Almost all current production radios utilize DSP IC Chips (Digital Signal Processing).
