Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Radio Sonder Grense 3320 kHz, Meyerton, SA

Hi there, the next in the series of comparison tests, this time using a stronger signal from Meyerton, but one which was suffering from adjacent channel QRM. You will notice the Sonys cope very well with the noise, but, as might be reasonably expected, even with a narrow filter setting, the Tecsun is far less assured in it's delivery of clear audio. In order to be certain the signal hadn't either faded out or become completely swamped in QRM, the video finally returns to the Sony ICF-SWS77 and once again, Radio Sonder Grense can be heard with reasonable clarity. Recorded at the woods in Oxford UK on 18/12/16 at 19:46 hrs UTC using a 75 metre longwire. Thanks for watching.
