Radio Fana: August 6, 2018. Radio Fana recorded outdoors in London, UK on August 6, 2018 at 1800 UTC, on the frequency of 6110 kHz using a Tecsun PL-680 radio and a long-wire external antenna. The transmitter is located in Addis Ababa, Ethiopia. This non-directional transmission had a power rating of 100 kW. Berthold standard bq regularly. Nov 28, 2017 - Eton-Grundig has informed us the Satellit 750 is currently not. It does appear Amazon.com still has inventory, but no doubt they will eventually deplete their stock. I've always liked the BNC antenna ports on this radio, the rotatable. I live in an area that will not allow me to raise a longwire antenna.

Left: AN-200 Right: AN-100 It has been a while since I last reported on passive AM loop antennasthe smallish variety that are such a cost-effective way to perk up your AM radio reception on the cheap. If you haven’t tried one out you’re in for a treat! The good folks at just sent me their Tecsun AN-100 to check out and as usual I pitted it against the well-known Terk AM Advantage AM antenna and a few others I have on-hand, such as the excellent but no longer available Select-A-Tenna. The Tecsun AN-100 is also sold in other areas as the model AN-200 which appears identical in every respect except for the style of the plastic basethey can be found under the names Grundig and Kaito as well as Tecsun. All will function identically.

These Tecsun antennas are beautiful antennassome might call them artful. Aesthetically pleasing and nicely designed and of good mechanical quality. Overview: Passive loop antennas are not a new invention – they’ve been around as long as radio has been. Long before highly efficient ferrite rod antennas were commonplace, early radios required either an outdoor wire antenna (called aerials in those days) or a loop antenna. Some loops were ornate and sat atop the radio, others, like the Zenith boxed loops pictured further down on this page, were mounted inside the console cabinet and could be “aimed” – rotated by a front panel knob for best reception. When smaller table radios appeared in the 50’s and 60’s they contained a loop of wire, usually wound on their back panel.

Loop Antenna On Back Of 50’s Table Radio Tuned vs Untuned: Loops can be designed either way and each has strengths and weaknesses. In common with both types is the ability to reduce RFI – Radio Frequency Interference. Loops respond to the magnetic portion of the RF signal and ignore the electrical component where most of the noise is. This is a prime benefit of all loops including the ferrite rods inside almost all portable AM radios which are, after all, simply loops made more efficient by their ferrite core.

By comparison, wire or whip antennas tend to pickup more noise. Ferrite rods and loops are also directional which allows them to be aimed to maximize reception or minimize interference. The main advantage of an untuned design is that it doesn’t have to be re-adjusted for each frequency you tune your radio to. Untuned loops can be very effective if they are large enough to capture enough signal. Such loops can span entire bands or groups of bands effectivelythe T2FD loop is one good example of an untuned loop. However, smaller untuned loops of the type that come with most of today’s typical table top radios or A/V receivers generally provide lackluster reception and are primarily a cheaper alternative to the superior ferrite rod these loops work after a fashion as long as signals are strong enough. Loop At Lower Left Can Be Rotated By A Front Panel Control Tuned loops such as this Tecsun AN-100 on the other hand can provide extremely high gain without any electronic amplification in a small size.
