Not on youtube and not free but cheap.  I highly recommend this course and instructor.  Sales go on periodically and right now it is dirt cheap.

The forecast is for rain and hail during net time at my QTH tonight, it is very probable that my Satellite internet connection will fail or at least be highly compromised during our scheduled net time,  I will try to run  the net but if my connection fails someone else will have to pick up the net  control role for tonight's net.

I remember well Garriott's 1983 shuttle flight. Our family lived in Honduras at the time and I marveled at the possibility of hearing the space shuttle. One day I was doing something outside the house and also monitoring his frequency on my 2m HT. Suddenly, the squelch broke and it sounded as if the guy talking was standing next to me. Sure enough, it was W5LFL. That was a thrill!

Re: How do I best operate a 4S-Tuner with a Doublet antenna ?

Gwen Patton
 

I've got an Emtech ZM-2 I built about a decade ago. Still works like a champ. It'll frequently tune what my Elecraft T1 won't. I needed to use it for my Cricket 30 because the antenna was really lousy, and the Cricket wasn't putting out enough power for the T1. I might get one of those QRPGuys multi-tuners, though, that looks sharp. I've got a lot of their other gear.

Bob,

I have been using WSPR for a couple of years now to check the effectiveness of my antennas for TX & RX.  In just a few minutes you can see just how your system is working, make some changes and re-test.  

I also check WSPR almost daily for real propagation in real time....... not a prediction but current condx and a map showing actual current results for any band.

WSPR (IPad/IPhone) APP or WSPRnet (computer software) are free offerings.  I am currently working on a presentation on this subject for a local club, if it all comes together I’ll share it with the group. (Use Google to find them).

As many, many have said before us, the antenna (including the feed line) is the most important part of your system....... almost 1400 miles between us, I was at 5w on an Inverted V and SHE was running 2w into a 3 element beam during not so great band condx.

Love to play with wire !

Hi Bob,

Your 4sqrp tuner is a great one, basically designed for use with a "random length wire" antenna and a counterpoise wire.
For portable use, the antenna could be anywhere from 20 to 80 feet, and the counterpoise from 4 to 15 feet.
The antenna wire on the red binding post and counterpoise on the black post.
However, you are using a dipole antenna with a balanced feedline.
I would first try it connected to the red & black binding posts, and see what results you get (signal strength and direction determined by call zones received). Then switch the feedline wires and test again. Then twist both feedline wires together onto the red post and a 10 ft counterpoise wire on the black post.
Compare data. Which gave best results?
A typical dipole at about 40 ft off the ground running North and South will have the best coverage to the East and West. If only 10 to 12 feet high, it will be NVIS and work best on 40, 80, & 160, and give omnidirectional 300-500 mile range.
Later, you can build a little 1:1 and 4:1 BALUN to try between the feedline pair and the posts.
That's the fun of antennas.
I don't think you mentioned what type of rig you have, but if it's portable, take it to a park with a spool of lightweight wire.
Take a fishing pole with a 1-1/2oz sinker, sling it into a tree, pull the end of the antenna wire into the tree and have a blast!
Cheers,
Frank N6CES

Hi all,

  Thanks for the replies.

  Frank, you mentioned a 4:1 balun. If I am connecting the 2-wire feedline directly to the tuner binding posts, how do I make / find a "bal-bal"? Or, are you suggesting that I use an actual 4:1 balun (2-wire feedline on one side, coax connector on the other side, and multiple turns of coax in between) and hook that to the coax antenna connector on the tuner?

  If I understand correctly, at 40m the Doublet will present roughly 50 ohms to the tuner. Since I can dial out most of the inductance and capacitance with the 3 knobs, I should be able to match with low SWR fairly quickly. 

  At harmonic shorter bands (20m, 15m, 10m), the Doublet will likely present with a higher impedance. Then, I can dial in increasing amounts of inductance and capacitance to match the antenna to the transceiver operating at the higher frequencies.

  I think that the tuner will really shine with some of other HF bands (30m, 17m, 12m). At those frequencies,  the Doublet will truly present as a "random wire".

  As you all say, I will know when I try it. Now that I have a feasible and highly portable antenna and tuner, I need to find a small HF transceiver to actually operate. Perhaps I can bring it to a Field Day or other operating event somewhere in central AZ and ask if I can try it with one of their rigs. 

  For my own rig, I am waiting until Hans Summer releases his QSX multi-mode all-HF band QRP transceiver. I Hopefully, his QRP Labs ( http://www.qrp-labs.com ) will make those available sometime this summer of 2019. 

  I am not yet CW capable and won't have time to learn Morse code anytime soon. Thus, I need a rig that supports SSB and maybe even some of the digital modes ( RTTY, PSK31, Olivia, FT-x, etc.)

Cheers & 73,

Re: W5LFL, ham astronaut passes

Sorry to hear that.

I recall that his operation from Columbia was a rather big deal and even
got a nice full page article in the Washington County (Kansas) News. I
was a newly licensed Novice so I couldn't take part and I didn't have a
2m radio at the time, but I remember the QST cover and article of Owen
in W5LFL. Several years later a job took me to Enid, OK, Owen's home
town where the main esat/west highway is named Owen K. Garriott.
Nothing special, just a personal memory.

God Speed, Owen, 73 es R.I.P., OM.

All,

I want to say I had a great time at OzarkCon!  Everyone I talked to was
very friendly and interesting.

I hope you all enjoyed the presentation on KiCad. There is a lot to
learn and I really had to go through it rather quickly. This really was
just a Show and Tell to give you an idea of the features and power of
the tool. There are many more features which I did not discuss and
probably questions from you which didn't get asked or answered. I'm just
a KiCad user and disciple spreading the word.

If you want to know more, here are a few links you will find of interest.

==========  KiCad Forums  ============

https://forum.kicad.info/ This is a great place to get help. Lots of new
users showing up on a daily basis. If you have a question, it may have
been answered, so please search before posting. You will need to create
an account and login.


==========  YouTube Videos =============

The current version of KiCad is V5.x   and many of the videos on YouTube
are older V3 or V4.  If the video is dated before about June 2018, the
info MAY NOT BE ACCURATE. There are still good videos for basic things
that are a year or 2 old.

I recommend 2 particular presenters, you can search for them by name and
see what they have.

Chris Gammel https://www.youtube.com/watch?v=iTyi3RvNoB0

There are also a number of videos made by Shawn Hymel for Digi-Key.

Thank you Barry for great presentation.
I was quite amazed at what Ki-Cad could do, even though my lap top had other idea's.

We may consider some additional smaller seminars next year, but right now were just try to breathe a sign of relief! 

Thanks for the recommendations of the other possible speakers.
