    Oh... where to start with this Eric Dollard character:

    1) The solar cycles didn't 'start' during the renaissance, that's just when Western science noticed them and started counting.

    2) The 'Dark Ages' had nothing to do with the sun. They refer to a so-called "intellectual darkness" after the collapse of the Roman Empire. There are those who suggest climate change over Europe during this period didn't help, but I don't know if there is any sound evidence for that.

    3) The sun "operating on half power"? Even allowing for hyperbole, is grossly misleading.

    4) Ask an astronomer if it's possible (or was recoded in 1980) for the Earth's orbit to wobble following a CME.

    5) Anyone who knew what they were talking about would never use the words "radio astrology" - even in a slip of the tongue.

    6) Sorry, I couldn't watch any more... It seems this guy has gleaned a few facts, not really understood them, and made a video.

    Yes, this solar cycle has been less active than we are used to. I remember listening to New York taxis on 40-odd MHz in the UK during the peak of cycle 21. That hasn't been possible this cycle - but maybe NY taxis don't use those frequencies now. But ask any HF broadcaster (BBC, VOA, etc,) how the sun's (in)activity has affected them. Not that much.

    There's too much misunderstanding distributed by (well-meaning?) pundits about the sun that is keenly consumed by those eager to be scared by what they don't really understand.

    I was a professional radio engineer. I use amateur radio frequently. I used it to chat to a guy in MASS, USA on 26 Jan and I was only using 10 watts of SSB on 21 MHz. The ionosphere is there and 'working' normally. Yes, really!!

    Meteor-scatter is a bit of an esoteric communications medium, although is (or was) used commercially for low priority, low data-rate communications, and is used by some radio hams. Moon bounce is another, possibly even more esoteric form of communications; it requires very high ERP and very high gain receive antennas. Not something easily done when the mains supply is gone.

    When the mains has been out for a month, and your solar panels and batteries are not working as well as the brochures said they would, get your Morse Key out if you need to communicate!

    Default Re: Ham radio information needed ( an unusual transmission - what is it ? )

    This is a recording of a recent transmission picked up in Virginia.

    Does anyone here have an idea of what it was ?



    Quote In the early morning on 1-26 I came across what sounded like ATC traffic on 5600 LSB. Sounded like the controller was in New York. I am located in Norfolk, Va. I could not find out exactly where it originated and if it was on any air traffic lists. If anyone could give me some insight as to what it was I would be grateful. I have tried on other nights since then to listen to that frequency and I have heard nothing else there. Thanks, M B

    Aviation traffic, complete with selective call tones. Probably trans-Atlantic where HF is still used when outside VHF range. There are many aviation channels in the 5 - 6 MHz range, and elsewhere.

    I've just read here that Eric Dollard is being hailed as a modern-day Nicola Tesla.

    Perhaps when he made the above video he was having an off day, or perhaps he was just testing - trying to see who's awake...

    Some very important questions have been asked about this on the forum - and I am really glad they have been. I am happy you posted this on that thread - so I'll follow the Eric conversation there instead of here.

    My solar panels and batteries have been in use for long enough now I can tell you exactly how well they will perform

    Lets just say, the word SOLAR is a bit of a give away about thier usefulness - the marketing hype is a secondary factor.

    Getting a solar installation up and running properly (ie: fully off grid) is very very expensive.

    If this is off topic please move this somewhere else. There has been some talk of radio communications and obviously HAM is the choice for long distance. If you are interested in a handheld to communicate with people for shorter distances, just to coordinate activities which might be useful in a small group of organized people. One radio you might want to look at is a Bearcom BC95 UHF radio. It can be modified by the manufacturer to operate in the GMRS frequency ranges and carries a full 5 watts of power. This in not one of those toy walkie talkies but is a genuine piece of equipment. You'll need to get a license (just pay a fee, like everything else in the world) to operate it.

    I bumped into this by accident yesterday:

    BAOFENG UV3R Handheld Mark II UHF VHF Dual Band FM 2M 136-174/400-470Mhz Radio
    I saw one on Amazon for sale for only US$ 35 ...

    It might go against some 'American' feeling because it is Chinese made. But hey, for that
    amount you can buy a couple of them. They are also 2 Watts 'only'. That is probably
    sufficient though (I had a 2 Watt handheld for the 2 meter band once).

    I don't know what GMRS is (possibly similar to CB?) But it might be in the range of 400-470Mhz.

    Does anybody have experience with this type of handheld? I am curious what the quality is.

    I have a mate who bought one of these. For the price he says they are very good. (They work even without a ham radio licence - don't tell anyone!)

    But bear in mind they only have a range of a few miles in open country, and much less in built-up areas.
