FM radio stations picked up in Letterkenny with Tecsun PL-606

While staying over in Letterkenny (The Elms area), I did a scan of the FM band using the Tecsun PL-606 with its antenna extension positioned vertically. This is a high sensitivity DSP FM radio which picks up fringe FM stations normally only picked up by a good car stereo or roof-mounted FM aerial.

The following table has three sets of readings for each station. The first column is from an upstairs window facing North West, the second is another upstairs window facing South East and the third column is with the radio connected to a loft-mounted circular omnidirectional FM antenna.

For reference, the following is what to expect from the readings:

  • NA – Total static to barely understandable speech.
  • 0dB – Noisy static, but speech still understandable.
  • 1dB – Moderate hiss, speech is clearly heard.
  • 2dB – Light hiss, unnoticeable with most music on internal speaker.
  • 3dB – Light hiss during speech/silence only on internal speaker.
  • 6dB – Hiss barely audible on internal speaker during silence.
  • 12dB – Stereo sound with considerable hiss.
  • 15dB – Stereo sound with hiss mainly heard during speech.
  • 20dB – Light hiss in stereo, noticeable during speech/silence.

For a rough comparison to a typical FM radio, this Tecsun radio’s sound quality in stereo is roughly what a typical radio picks up in mono. Most stations with a reading below 10dB either give pure static or obscured by a nearby stronger station when tuned on a typical FM radio positioned in the same spot. For example Q Radio on 101.2MHz comes in perfectly clear on this Tecsun radio, but on another radio I tried in the same spot, the much stronger nearby station Today FM on 101MHz is instead picked up on 101.2MHz.

The following are additional stations (including Cool FM above) with careful positioning of the radio to achieve the highest reading I could get.  For Cool FM and U105, I positioned the antenna horizontally.
