1. LF: Experimental linear amplifier testing. (score: 1): Author: LineOne <[email protected]>; Date: Thu, 16 Oct 2014 17:13:57 +0100; This is to confirm that I am running some tests on 136.173kHz, QRSS60, latterly 150W dc input to a linear amplifier, mainly to determine aerial tuning and loading. I was too close to 136.172 earlier; /rsgb_lf_group-archives/html/rsgb_lf_group/2014-10/msg00216.html (8,648 bytes)

I was getting a signal on 'your' frequency until about ten minutes ago, but only switched on shortly before that and it's now disappeared.
