Hi Steve These VLF stations are currently more or less active: 16.4 Royal Norwegian Navy, Novik Norway 18.1 Russian Navy / Strategic forces, operating from 6...
Thanks Hans, It would have been about 14:00 local time in Victoria (I think) at the time of my recordings so the sun would have been up high there. I know the...
I have been working on a VLF system here and think it is working properly but would some of you look at the two JPEGS at the link below and tell me what you...
I should add there is a wee bit of Cutler Maine there also. It was much stronger during the daylight hours. I am observing the magnetic component and have a...
Hi Brian I am a fair way away so it is not easy to comment. It looks like you have a large TV timebase signal at between 15 and 16kHz and a lot of 120Hz lines...
Thank's Alan. I have a ways to go but hopefully this is a good start. Brian ... looks like ... lot of ... frequencieqs ... levels are ... and ... antenna ... ...
Hello Brian and VLF group Good to hear from you again Brian ! The 3 signals at 21.4 24.8 and 25.2 is the US Navy transmitters at Lualualei Hawaii, Jim Creek...
VL3DEF does not appear to be operational at the moment at least there is nothing heard on 18.3 or 18.6 here just 580Km away. The station is reputed to have the...
I made a few changes here and all the TV and mains noise cleaned up. Even with all my own TVs running! If Trond's list is correct I should be seeing Jim Creek,...
Hi Brian , well done, that is a brilliant exposition of what can be done to improve the hum and TV noises on a VLF receiver. It is not easy to get that clean...
Alan, Take a look at where I live! Find the arrow and it points to my rooftop where the coil is. I am in a city of several million people right smack dab in...
Alan, After sunset Hawaii at 21.4Khz is observable. http://electricterra.com/VLF/Night.jpg Please excuse my excitement but I have been working on trying to do...
Alan, I think I have tied up the conversation too much here so I will leave things with this last post for awhile. It is now several hours after sunset and in...
Tonight at about 0430 UTC a station on 18.1 kHz came on with what looked like BPSK for about a minute and then went to an unmodulated carrier for a few...
By the way Steve. Thanks for your help also. I'll try to get a schematic posted this weekend if any one is interested. Brian ... Hawaii on ... you ... VLF ... ...
Hello, Brian! Most interested in a schematic, when you can post same. Very best 73 Herb Balfour VE3OHH Brian <side7@...> wrote: By the way Steve. Thanks...
Hi Brian that looks good, but the actual signal levels of these is still quite low. You could do with winding in some more gain now, I guess, until the...
Alan, This is an interesting set of frequencies. An hour ago Hawaii at 21.4Khz. was as strong as the others and Cutler, Maine was non-existent. I must admit I ...
Hawaii faded from site but if conditions are like last night it should build later in the evening. http://electricterra.com/VLF/HIGone.jpg I think I can run a...
Hi Brian, yes most of my "work" is a little higher in frequency I monitor 136kHz and try to understand the propagation there. Generally propagation conditions...
Very good Alan, As I thought Hawaii is on the rise. Just before sunrise it should peak nice and strong again. http://electricterra.com/VLF/HIrising.jpg I'll...
