I notice that antennas in use in the UK are useless for weak signal reception. Only one stn in the UK can decode my signal. For MF using the proverbial joy stick antennas are like using a match stick dipped in water mal/g3kev -----Original Message----- From: LineOne Sent: Saturday, December 05, 2015 12:08 PM To: rsgb_lf_group@blacksheep.org Subject: LF: Variation in my Rx signal reports on LF If anyone noting my signal reports, WSPR in particular, is puzzled by large variations, this is because I am switching between aerials. Best results are on the main Tx aerial into my R5000 but, failing a suitable giant relay, I have to use experimental systems instead. Thanks to GW0NOS in particular I am able to compare results. The latest aerial is a long ferrite rod with high-gain amplifier, end on loss is about 10dB. Due soon is a vertical strip in a tube, I understand height must be the main factor with these. Hugh, M0DSZ
