Centuries past there was a cold spell on Earth where it is stated
radiation propagation did not occur because of the lack of sun spot observations. This period lasted about 30 years if my memory is correct. Now we appear to be in a state of global warming presumably because of the actions of the Suns vibrancy which would suggest the present increase in sunspot activity of the past century will continue to increase and the next Sun spot cycle will be a good one. So don't give up on antenna experiments just yet as the particulates will be a coming Art KB9MZ...xg |

I do believe it was in the early 1800s because the River Thames froze in London such that they were able to have a fair on the ice.Remember the river is tidal !

Soooooo you will have to go to the library and look at back copies say for four months and then you will find it. When I say early 1800 I remember seeing the old sailing barges on oil paintings of the same era which traveled up river from the tidal basin where my grandfather was a customs inspector I was born in the docklands less than a mile from the Tower of London so the rivers history stays with you as well as the destroyed residence near St Georges!. I remember waiting for the tide to go down and then pick up pieces of thrown away clay pipes of Elisabethan times in the hope that I would get a match. Very Very difficult to do but I guess they only used the pipe once and then threw it away thus many pieces. The docks were all bombed and set afire with magnesium so it was natural to demolish them when shipping boxes came into fashion and they moved the docks to a sea port on the East coast. Union tickets were prized for workers as they were handed down in the family One Uncle was a stevedore but I turned the ticket down to become an engineer with peanut salary! Art Art |

Otherwise the unlicensed 18 wheeler transportation industry will take it over for us. Sunspot are not the only indication of Neutron release just an indication somewhat under a solar flare where release includes particles of more than half life such as wreckage/ debris and fumes. The rotation of the poles ensure fracture of the arbitrary boundary for emmisions of particles but if the Suns core cools due to the pole shifting then there is less expansion within the boundary providing less straying from equilibrium. Now with the earth heating up scientists say that the sun is expanding and in a zillion years will swallow the earth no less, A extra large flare or eruption literally is a releaso of nuclear energy which goes to power lines as an impulse similar to the electrical outage created in Hawaii when they exploded a hydrogen bomb at low elevation.Which is why yhe Navy suddenly reverted back to tube technology with radios. In each of these cases it is the debris composed of more than half live nuclear products which does not compare to the miniscule energy of a unbound electron called a neutrino. However when neutrinos congregate in bunches they have a large energy input creates by color binding which when split apart creats an aurora for thousands of miles which amount s to a lot of energy release within our arbitrary border which some say provides energy to the upper atmosphere and provide worldly circulation of weather clouds, storms e.t.c. Certainly a lot of speculation with regard to the arrival of particulates the majority of which have not been identified. Nuf said |

The poles of the Sun never stop turning or burning so periodically the arbitrary boundary must have fissures that allow for the escape of low level neutrinos.

My point: HF still works at the bottom. You will be astonished when propagation comes back to life. I used to work Austrailia daily with 5 watts FM into a dipole DFQ. More than half of my DX cards were from chance contacts while I was commuting to school. The other half was mostly from ARRL DX QSO parties. Last Field Day I worked 1 Canadian as my only DX contact. Truly SAD. A few years back I worked Asia on 50 watts CW and more than 100 DX contacts despite a continuous pileups from band edge to band edge. For the interlopers on 10 I suggest regular code practice sessions. Long CQs from the keyer can help with that too. Rest assured they will be drummed off when propagation comes back and the bands are full. For the time being, there are rare opportunities. Learn about the beacons and DX clusters. Some of us have time on their hands and some don't. |

In fact I have only heard just a few repeaters there since the early nineties. Tell you what: Better the band is full of ham kerchunkers and being used than not being used by hams at all. As I recall, demand by the CB services is what caused us to lose 11m and it also could cause us to lose 10m. Ten meters reminds me of Lake Superior in Wisconsin some years after the opening of the St. Lawrence seaway. Lake Superior was a thriving resource fishery at one time for lake perch and lake trout. The opening of the seaway brought in the sea lamprey which killed all the fish. With no fish, even the the lampreys died. By the 1970's, Lake Superior was like an empty aquarium: No fish, clean and clear. Unused. Empty and and unused like 10 meters today. |

In fact I have only heard just a few repeaters there since the early nineties. I guess your radio's numb then. When the sunspot cycle kicks in it happens every day. Skip causes way too much QRM because of PL duplication. It was bread and butter for the radio company because so many customers would complain and complain and complain about "other people using their frequency" and they couldn't block them out with the mic hanger. Lots of commercial users left low band FM for VHF and above because of that and because a gain antenna needs to be so big that they don't last a year at a repeater site. Ten and 11 meters is considered to be useless because the daytime absorption is so bad it limits range to worthless. FCC made a mistake to put CB on 11 if they didn't mean for them to play skip. And if it weren't for modified CB's we wouldn't have a problem with interlopers at all. As far as I know, most of the Ham Bands are useless for commercial exploitation either because they are too small of a block like 220 was, or because they aren't in the propagation sweet spot for a particular usage. Hence, they are left to HAMS to experiment and toy with. That doesn't mean we shouldn't be vigilant and fight tooth and nail when some idiot tries to sell somebody onto our bands. The real shame is that we LET GO of half of 220 just because UPS asked for it, and because a bunch of newbie no-code techs that flooded 2 meters at the time had convinced themselves FCC might cut 2 meters if they couldn't have 220. They were even crying to "take 440 if you have to, just spare 2 meters". If it weren't for that NOISE, the FCC might have simply denied the petition on recommendations from those in the know. So the Ham repeaters and control links that were on 220 either had to go away or move to 2 and 440 anyway. That was a boondoggle for everyone involved since most wanted to go to 800 anyway. It's been a money LOSER for everyone that invested in it. Now Hams can't get it back because there are a few ACSSB systems still there that customers got stuck with. |

How do we want to use 10m? 1. Use it all the time similar to 2m using repeaters and some simplex, or 2.

Truth be told, 10m most of the time is more suited for 2m style operation than 20m style, again, most of the time. Again, 10 and to a great extent 6 also, are unreliable 7 to 8 years out of the 11 because of the skip. As for the interlopers, When the band is down, they will be using it, we won't know about it because we can't hear them and they can't hear us even if we ARE using it. In fact we usually can't hear each other when we are using it so how can you say it isn't being used. When the band is up, then we can do something about it, but what good does it do to trash the band with uncontrolled repeaters, so that we can't use it either. The thing is, it is a doable thing, but most people aren't doing it right. You got to think ahead, think of the other Hams, and ask questions. Never be afraid to ask as many different people because the only people who aren't humbled are the newbies that think they know it all, but haven't done it yet. Actually, I'm all for remote bases in lieu of repeaters because when the band is up, everyone forgets to shut down their repeaters so people can use the frequency. Fully automated stations render us all obsolete. Another possibility is to use Touch Tone Access to activate the repeater, which will time out after 10 minutes or so if no one is using it, and forced TT shutdown as well. This allows usage without leaving it to thrash by itself. Antennas are a big problem. If you have mountain tops, Ice, snow and wind kill antennas a lot and the large 6 and 10m antennas are by far the worst. Several groups have 6 and 10 but every time they get around to replacing the antenna, it's cool for a few months then it all goes down for a couple of years until someone finds a good deal again. If you don't have mountain tops, you are just as well to use VOIP links to different home stations all over. This is like how FCC and Coast Guard operate. They have base stations all over that they can dial into remotely. There are actually several Multi-Band, Multi-mode Ham stations already around that you can get in on with the right software and DSL line. You can put yours on line too. Google TS-2000 remote and look into that. Look up IRLP too because there are repeaters and remote bases that can be controlled via IRLP from all over the world and some have 10 and 6 capabilities. Keep an eye on the beacon stations too or monitor 29.6 FM for band openings because that is where it's at. If you do have a multi-band mobile you CAN always QSY to 10 for local stuff too. Don't expect that to chase off any interlopers in the next town though. |
