Hey guys,
Anyone have any experience with this particular key?
Here is the link Vibroplex Code Warrior Juniors CODEWARR-JR

I think I am going to pull the trigger on this key.
So if you have anything good or bad, please let me know.

Hi Gil,
I do have an Unun end fed but was just wanted to try a little something different.
I just wondered if there was a magical length for a multiband dipole, not a fan dipole. I would bring my Jackite pole but wont fit in the helicopter....

But I will probably stick with the trusty end fed with a long wire. I will be competing with the wind so I will try and tie it off on the lower deck and hope for the best.

Thanks!

I have also been enjoying your YouTube video's!!

Antennas / Using a dipole for bands other than what it was made for?
« on: June 08, 2017, 08:45:37 AM »
Morning all.
While field day is a few weeks away, I will be operating from my work location when I can. An oil rig in the Gulf of Mexico.
I am limited on space for the flight out to the platform so I am only going to bring a wire antenna. I have different home-brew dipoles.
I do not have an analyzer but my KX3 will tune the bumper of a '57 Chevy!
Anyway, on to the question, using a dipole for other bands than what is was designed for....

When using a dipole and tuning from 6-40, is there a specific length that I should be aiming for?
I mainly use monoband dipoles, but I will not have the luxury of multiple antennas or the time to take down and put up another, I need to stay with 1 dipole.

I do have an end fed that works 6-40 and may just set that up but would rather a dipole.

Thanks and have an awesome day!

Thanks guys.
I found a Diamond DL-30A that works good enough for what I need.

Antennas / Dummy Load
« on: October 02, 2015, 07:29:00 PM »
I am looking for a good dry dummy load.
Nothing bigger than 100 watts.
Using for my KX3.

Any recommendations?

Thanks,

I totally understand.
As with me, I am away 2 weeks at the time.
While I would have my QRP rig with me, there is no telling if the workload will allow me to get on the radio or not.

Maybe we can pull something together this winter when we all have more time at the radio.

Thanks guys,

Gil-

Point taken.
The object is to get as much radiated power to the antenna as I can.

So maybe a mono band end-fed should be what I am looking for.

A wire cut to resonance connected directly to the radio could do the trick?

With this one, you match the impedence at the wire, not the radio, much less loss in the coax.

Gil.

Gil,
I looked up the unit and seems that it will not handle full power of the KX3, unless I misread as I did just glance at it. I think it was 10 watts P.E.P.
I like a little but more room if I need it. Also, I really wanted the 6-40 meters, or 80 meters even. Maybe just a longer wire may get me the bands I am looking for.

While I haven't ruled the unit out, I do like the way it works, as you said matching at the wire, not the antenna, efficiency.

Are there any others you would like to share?

Thanks,
-PuJo

If you get on HF on the rig, let me know. I'd like to try and work you. Off topic: Have you returned to Facebook yet?

Hey Deer Whisperer, I will defiantly let you know when I'm set up for HF on the rig.
Lots of stuff to do before I'm ready.  Still need to get everything into the pelican and just get everything the way I want it.
At this point, I am just trying to find the perfect antenna for my needs while I am on the rig.

I still haven't returned to FB, I don't want to subject myself to all the unnecessary drama and selfies  :P ;D

Thanks guys.
I am thinking about purchasing this unit. http://kx3helper.com/endfed-40-6m-antenna
Unless one of you know of a better end fed. If so, please post a link.

Thanks,

You are correct packing should not be an issue, however it is for me.
When we go out to the platform it is by helicopter. We are limited to two bags. My regular bag, and I was hoping to use a pelican for the radio and hold everything as well.

Using the RG-8X may be more weight than my telescopic crappie rod can handle....
I have to try and keep the weight down to a minimum if I strap coax to the rod, then hand the antenna at the end.

Would RG-8X be the best choice for this?

Check out this coax, let me know what you think. http://www.picwire.com/pdfs/PIC_Overviews/PIC_50_Ohm_RF_Product_Line.pdf

What about feed line.

I've seen hams use RG-174 portability and packing.
If I use the fishing pole method, I would need close to 50'.
I haven't seen the specs on RG-174 but guessing that there would be lots of loss.

Recommendations?

Thanks,

Antennas / Antenna
« on: September 05, 2015, 09:10:16 AM »
Morning guys.
I have posted this question on other forums and getting mixed answers.

I have a KX3 W/ATU, DRF, etc....

I want to operate from the gulf on the oil rig I work.
Antennas always the question.

My options are to get the Super Antenna MP1 and set it on top of the helideck that is a 40'x40' square iron plate, or an end fed wire antenna hanging down the side of the structure.

I do not have a antenna analyzer so getting the MP1 on the spot would be kinda hard, but not impossible.
I wanted the MP1 for super fast deploy and retrieval. Helicopter on a 5 minute final is all the notice I will get to retrieve the antenna.

End fed 9:1 unun or without balun is the other option.
I can let it hang downward toward the water however it will be extremely close to the metal structure.
Using a fishing pole I could get it away from the structure somewhat but its windy out there.

If I use the wire antenna without a balun, I would still have to use coax ran down the fishing pole to the wire.
Should I just use the 9:1 unun balun fed with coax to the end of the pole then start my wire?

Not sure how to setup or what to use. I'm looking for opinions. Now that I am 100% QRP/P I do not want to invest in big antennas, but I do want effectiveness.

Look at the image below, I am on top with my Arrow working SO-50.
Any ideas on how I could try and setup an antenna??

The platform is pyramid shape and I would like to operate from the highest point. Its a long walk from the bottom to the top with your gear.
220 steps to be exact!!

Anyway, what do you all think?
