I hope I am posting in the right category:
Over the past several month I have found HF frequencies that have Ale Soundings when searching across the hf bands and I have not found any information on these. They are all USB and the frequencies I am posting could be off +/- a few khz's. These frequencies I have heard during the day and night, I dont think I have picked up any audio on any of them, I thought I would post them to see if anyone had any information.
All IN KHZ USB
5330,6809,6994,8038,8624,8899,8926,8936,11109,11181,11227,11427,12217,12877,14777,14872,14929,15045,15092,19313, AND 21867.
I have been picking these up from Fort Erie Ontario Canada using 100ft of antenna wire out on my fourth floor balcony facing North using a SDRplay RSPdx and SDRuno software.
