My HF rig (20 and 40m) is causing hum in Audio/TV System. Help!

Howard E. Mahran / WA1HEM
 

When my rig is transmitting we are getting a terrible buzz in our home stereo/TV system. What might be solutions?

Thanks!

Well said, Paul.

I have a question about stringing up antennas. I want to raise my OCFD but if I do, a good part of one end and some of the other end will run through tree branches. Is that going to be a significant issue?

I just don’t want to have SNOVARC members thinking “You know, I’d put up a <new antenna> if only I had a way to get a rope over the big tree.”

Doing this stuff is *fun*.  It’s not a burden.

I could help other hams do stuff as much as I can for the rest of my life and I suspect I would still fall short of how much help I’ve gotten from other hams.  I would just point out that in general I’m getting more help from others than I do the helping.  It’s just that often the help I get isn’t very visible to other people.  But I ask for help all the time.  ALL THE TIME.

What will make the Sno Valley more resilient in the face of some disaster is having a thriving ham community.  What builds community fastest and most firmly is helping one another.  It’s as simple as that.

A number of folks have been eagerly awaiting a progress report on my efforts to hang antenna support lines using a drone.

This afternoon I successfully put a rope in an excellent placement over a 85 foot tall Douglas Fir.

Equipment is:
* DJI Mavic Pro Platinum drone
* dronefishing.com payload release
* drop weight consisting of a tennis ball with 200 grams of pennies inside and a wire loop threaded through the ball.
* Teflon coated Spectra fishing line
* bright orange nylon twine

Process:

One end of a 1.5m long length of fishing line has a loop that is captured and then release by the payload release.  The other end is attached to the tennis ball.  The fishing line to be place over the tree is tied to the tennis ball as well.

Step 1:
fire up the drone and lift off, hover at about 6 feet.  With the drone hovering, place the loop in the line that goes to the tennis ball into the payload release and close the release, so that the tennis ball is now on the ground, a short line runs up to the payload release.  The fishing line to go over the tree goes to the spool held by your Trusty Assistant.

Step 2: 
fly the drone up and on to the approach path to the tree you want the line to go over.  With the camera horizontal, fly up until the highest part of the target tree is now below the horizon on the camera, and note the altitude.  Ascend another 10-15 feet so you are sure the tennis ball will clear the tree as you fly over.  While you ascend your Trusty Assistant is letting the line pay out and keeping it from tangling in everything including the line itself.

Step 3: fly over the tree, taking care to pick a path that will place the fishing line trailing behind the tennis ball over the limb you want.  It helps if at this point the camera is pointed directly down.

Step 4: once the drone has passed over the tree and you’re directly above the spot you want the weight to hit when it’s dropped, make sure the target area is free of people, kittens, puppies, and other items of value.  If it’s clear, hit the button to release the tennis ball, and watch in rapt admiration as the ball drops neatly onto the exact spot you had selected.  it’s best to give Trusty Assistant a heads up just before you hit the release, so they can be prepared to let the line spool out freely as the ball drops.

Step 5: 
Fly the drone back to a safe landing area, being careful to not hit the tree you just placed the line over.  Land the drone.

Step 6:
Go find the tennis ball, which will be surprisingly close to where it hit the ground.  Tie the bright orange nylon line to the fishing line loop, then detach the fishing line from the tennis ball.  Now go back, grab the other end of the fishing line, and have Trusty Assistant pay out the orange nylon twine as you reel in the fishing line, pulling the nylon twine over the tree.  At this point you’ll be able to spot the twine as it goes over the tree and you can assess how well it’s placed.

Step 7: once you have the nylon twine over the tree you can detach the fishing line from it, and bend on the rope you want as the final suspension rope.  Then you can go back to the other side, and use the nylon twine to pull the rope over.  Make sure the ends of the final rope cannot be lost or pulled up out of reach.

You’re done.  Next step is use the rope to hang your antenna.

Some observations: 
* a light breeze doesn’t interfere with flying the drone but will affect how the fishing line hangs as you fly over the tree.  Doing all this during a still period would be a good plan.
* it’s far, far easier to put the line where you want it using a drone than it is doing it will an air cannon.  Much, much easier.
* With an air cannon it’s often a trick to find a good place to stand when you fire the shot, as often there are inconveniently placed objects line houses, trees, etc. in the way.  You don’t have that problem with the drone.
* if you don’t have a good takeoff/landing area for the drone, and a clear flight path to get the line over the tree, you would be stuck.
* the tree I put the ilne over was about 85 feet tall.  I put the line over a branch that is right at the top, a placement that’s hard to achieve with an air cannon.  The same quality placement could be done without increased difficulty and trees 150-200 feet high.  The altitude simply makes no difference.

Having worked out how to do all this I’d like to spread the knowledge far and wide and I’d like to get some practice by putting up lines for anyone who might want it done.  If you want lines put up, or know someone who does, contact me or pass on my contact info as appropriate.

hanging antenna lines with a drone

6 Meter tune up

Tom WA7TBP
 

Hi everyone:

Sorry for the delay in getting this out. I was in the RV for a week. There are two attachments. One is the criteria for the signal report (i.e. 5-9). The other is an Excel sheet showing who participated in the exercise, the signal report at the net control station. There are separate columns for the SSB and FM tests. I am sorry, I could not find my note sheet of the signal reports I sent out to each station.

I hope you enjoyed the 6 meter tune up. I think we will very likely do this again. If you have any questions, give me a call at home, 425-333-4833 or via e-mail, tomwa7tbp@....

See you on net tonight.

Tom


Re: Winlink Express and Winkling.org question

Winlink is a store and forward email system.  Messages sent are queued up and once another station, be it Telnet, VHF/UHF, HF or  Winlink.org connects, the message is sent to that station and deleted from the system queue. So only one station will receive the email message.

You can even have several stations with the same callsign.  The email message will be sent to the first station that connects.  Stations running RMS Express (winlink) are unique, even if they are all configured to use the same callsign.  For example: If I was to send a message to KE7GFZ from my account W7ABD.  That message would stay in CMS queue until a KE7GFZ station connects.  if two KE7GFZ stations connect one after the other, only the first station would get the email message.

I’d never used the webmail interface on winlink.org.  Cool.

I have no idea how many emails I’ve sent using Winlnk.  Dozens for sure.

There is nothing in the Winlink sent folder.

So I’m guessing sending something via Winlink does not make that something appear in the sent folder you see in the web mail interface.

I bought a giant 8ft arborist slingshot, line and beanbag 10 oz weight. Company rebranded as Notch.  All from Amazon. Arborist line is pricey but glides on bark and has exactly the slight amount of elasticity; too little and it gets stuck easily, too much and you lose control.

If you're looking for closest available launcher, there's a D-I-Buy pneumatic launcher on Craigslist for $100 in Spanaway.  You'll want to ask questions about the construction of this one, and make sure it's solidly built.  I have doubts as it's built with black pipe which is sometimes DWV plastic and rated to low PSI values.

Re: Quad band antenna?

Jackson Beard
 

MFJ electronics have previously suffered from poor quality control,  but the 347 is a mechanical part that holds screw in whips. Not a lot to mess up.

Bob,
The GP-15 is exactly what I was thinking. Wondering, though, if adding 10m in one antenna is worth any compromise. I expect to have great propagation from the QTH. MFJ does not have the best quality reputation so I have sort of ignored considering its antennas.

After last week’s new ham net, I checked out a few of the ideas.  My current direction would be the GP-15 for 70-2-6 with the MFJ-347 for 10m.  You may want to check out YouTube for videos on MFJ-347 to see how others have done it if you are not already familiar with it.

Looking for comments on quad band UHF/VHF antennas. Too much compromise? Tri-band instead?  Favorites? I am jazzed about 6m FM now and think I might as well add 10m FM so I do not need to use my HF antenna on 6 and 10 FM. I am hoping to roof mount a new quad or tri lashed against a chimney on a metal roof.

Diamond makes the CR8900A quad-band antenna.  I dont know if they are still a production item, but I see there are some on Amazon.  I have one that I am not using if someone wants to test drive it.

Ok, now that I’m fired up about 6m I also am looking at antenna options.

I don’t see any quad band solutions.  If you’re excluding beams of various descriptions, the best solution a short search came up with for me was something along the lines of:
Diamond CP610 dual band 10m/6m
Whatever your choice is for dual band 2m/70cm (e.g. Comet GP-1, GP-3, GP-6 and the equivalent Diamond and Hustler entrants)
separate feedlines for the antennas that connect to a diplexer to sort it out into 6m&10m/2m&70cm

But I am pondering some sort of low gain beam, aimed more or less WNW from my place.  Two element Yagi or a Moxon or even a quarter wave vertical with a reflector offset to the side.
