Portable Wire Antenna Weight
Locked
 
|
A warning.........be careful using a golf ball to put your antenna over a tree. I did the same thing about 15 years ago, except I drilled the golf ball and tied braided nylon cord through it. Inevitably the ball got stuck in the 'V' of a branch so I heaved on it, winding the cord round a piece of wood to give me more grip on it.
That cord must have had a breaking strain of more than 300lbs and when the ball broke free, I literally shot myself in the foot, breaking several bones. It could have been even nastier if it had hit me about 3' higher! I can still hear the staff at the Accident & Emergency Department sniggering when I told them I had been shot by a golf ball. My XYL had to drive me to work for the next 6 weeks while my foot was plastered up, bless her! These days I use a catapult and a lead weight which could be even more dangerous, but I use monofilament and am very, very careful if I have to pull the line back. Do it slowly and, with luck, the weight won't wind the line round a branch. 73 Tom G3OLB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I picked up a used MC-60 mic at Dayton. When I try to use it with my K3,
as soon as I connect it via the 8-pin foster on the front the frequency starts to scan like I'm holding down the up button on the mic. Thinking that there was a problem with the mic I tested it with a Kenwood TS2000 and it works perfectly. You push the up button and it scans up, etc. Now what puzzles me is that I used to own another MC-60(that I sold) and it worked correctly with my same K3. I'm wondering what could be causing this before I start to take everything apart. Anyone else run into this, does anyone have any ideas? 73 Jeff kb2m ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Jeff,
Is there any chance that you have an MC-60A instead of the MC-60? They are not the same. If so, I suggest you set the mic amp switch to OUT and disconnect the wire on pin 5 inside the microphone. If you need the mic preamp either use batteries in the mic or connect the wire that was originally connected to pin 5 onto pin 6 (Note that the mic preamp will no longer work with a Kenwood transceiver). 73, Don W3FPR On 6/18/2011 3:39 PM, Jeff KB2M wrote: > I picked up a used MC-60 mic at Dayton.

Thanks Steve that did it. I don't need the mic up and down buttons so
disabling them in the K3 config was the answer. 73 Jeff kb2m -----Original Message----- From: Steve WU9B [mailto:[hidden email]] Sent: Saturday, June 18, 2011 16:08 PM To: Jeff KB2M Subject: Re: [Elecraft] K3 with Kenwood MC-60 Try Config: MIC BTN OFF (as opposed to ON) 73, Steve WU9B On Jun 18, 2011, at 12:39 PM, Jeff KB2M wrote: > I picked up a used MC-60 mic at Dayton.

I use a 12ft beach caster fishing rod, 40lb line, 6oz surf lead weight.
I can shoot a line up over a 60 / 80 / 100ft tree with ease. Splice some 2/3mm rope on the weight end( after removing it) with the fishing line, i use white tape, reel in. Works every time.

I spoilt myself a couple of years ago and bought the combined fishing reel
and slingshot from the US. I got it over the top of a 50 foot fir tree in the front garden, exactly where I wanted it first attempt. I could hardly believe it! It hasn't been used since unfortunately! 73 Stephen G4SJP On 19 June 2011 08:08, Ken Chandler <[hidden email]> wrote: > I use a 12ft beach caster fishing rod, 40lb line, 6oz surf lead weight. > I can shoot a line up over a 60 / 80 / 100ft tree with ease. > Splice some 2/3mm rope on the weight end( after removing it) with the > fishing line, i use white tape, reel in. > Works every time. > > Ken..G0ORH > > Sent from my iPhone > > > > > > On 18 Jun 2011, at 21:01, stan levandowski <[hidden email]> wrote: > > > ....and that's why I used 8 lb. test fishing line instead of 300 lb > > test nylon...... > > > > ;-) Stan WB2LQF > > > > > > On Sat, Jun 18, 2011 at 3:23 PM, Jack Chomley wrote: > > > >> On 19/06/2011, at 5:11, "Tom Boucher" <[hidden email]> > >> wrote: > >> > >>> A warning.........be careful using a golf ball to put your antenna > >>> over a tree.

FWIW my favourite method to place a line in a tree makes use of a strong but
light fibreglass pole almost 10m in length, through which runs a drop line. It does takes longer to place a line than when using a missile system, about an hour to place a line at 100ft in a tall pine exactly where one wants it so not very useful when operating "portable". Because a tree's branches are used as hoist points for the pole on the way up, the pole must not weigh too much when placing a line in a tall pine, whose lower branches have long gone leaving short "branch stumps". 73, Geoff GM4ESD ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I use a similar system (10 ft rod, 20# test line) with a tennis ball
filled with 23 US pennies. The tennis ball works great, and does not annoy neighbors when used at home. I use a snap swivel on the end of the line. I cut a slice in the tennis ball to insert the pennies. A sail needle was used to sew up the slice and to create a loop. The snap swivel clips to the loop to toss the ball. When the ball reaches ground, I change the ball for a light line, and pull it through the tree. I then use the light line to pull the antenna, or pull a heavier rope if needed. My trees top out at about 70 feet.

I use a arborists throwing bag and slickline. All fits in a small bag a bit
larger than a softball. With a little (very little) practice I can easily put a line up 50ft or more. The slickline is fine to haul up a temporary antenna as well like an end fed so no additional messenger line required. Much more compact that a fishing rods etc for mobile use. I use the same setup to haul up heavier ropes with a survival saw to remove limbs that grow out near my home dipole. Works great for trimming limbs much higher than my pole saw can reach. I've taken down 6"+ sized limbs this way. 73 jim ab3cv ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I use various methods to get a sinker over a tree limb, and have been
successful at heights over 100 feet -- but rarely on the first try! I have found that trying to pull the weight back directly, invariable results in a pair of unintended half hitches around a limb high up in the tree. No matter what, I force myself to unhook the weight and pull back just the line. I make this easy by using a small safety pin looking clip, not sure what a fisherman calls it, but available from fishing tackle stores, to attach and remove the line. I also paint the sinkers bright red, and use fluorescent colored line to aid finding the end in the bush. No broken feet (or line) yet!

Can you explain how this system works in a bit more detail? I have some very high trees to use but because of clutter and the shapes of the trees I have never had much luck getting a line over the higher branches I do have a 10m pole and would be more than willing to invest an hour or two to get a line over a choice upper branch On Sun, 2011-06-19 at 13:58 +0100, Geoffrey Mackenzie-Kennedy wrote: > FWIW my favourite method to place a line in a tree makes use of a strong but > light fibreglass pole almost 10m in length, through which runs a drop line. > It does takes longer to place a line than when using a missile system, about > an hour to place a line at 100ft in a tall pine exactly where one wants it > so not very useful when operating "portable".
