yes Gerhard, Stefan mentioned that he was loosing about 3 dB because the ant is not quite on resonance today (current about 0.5 A instead of 0.7A). Interestingly, 5.17 is much clearer here in Nuernbe
Also good copy of the 5170 here but on Stefan's last experiment the 5170 was better than today. (compared to today's signals on 8970,6470..) So either noise level is higher today on 5170 or something
