PA3CLQ's Leuke Linken Nr. 443

Independent Telegraph club CQCW invites you to join the club members.

Our organization is still very young (2013), but already unites more than 450 (Today 12-10-16) 464 members / radio Amateurs from 54 countries of the world.

About the policy and the rules of the club can be found at our website:

Monoband antennas

To expect any reasonable performance out of a non resonant antenna tuned at the end of a feed line is very optimistic, unless the feed line is optimized to present a good impedance transformation.

    The impedance at the antenna is probably far from the impedance of the feed line and losses high.

Electrically small loops can have high circulating currents and these currents in the feed line add to the losses.

To have any performance the small loop needs to be capacitively tuned at the antenna and the resulting high impedance matched to the feed line.

    If by some extremely unlikely chance the 80 meter dipole were perfectly matched to the antenna at 40 meters it could have directional losses ( gain).

Would these gains be in the wanted direction?

Coupling this with the more likely feed line losses the poor results are as expected.

    It is not easy to make electrically small antennas work well but given some careful design and very serious minimization of resistive losses one can achieve remarkable results.

    An antenna tuner right at the antenna would mostly eliminate feed line losses.

If the antenna were perfectly matched and with no resistive losses in the antenna or the tuner and the antenna radiation was omni directional you would have a lossless antenna.

Getting the resistive losses down gets exponentially harder as the electrical size shrinks.

The K3Y 2017 announcement has been posted to the ARRL Special Event Listing......

and will appear in the January 2017 issue of QST.

You can see it here:

Just type in callsign "K3Y" to see it.
Pls let me know if you see any mistakes.

Assuming there are no typos feel free to submit the info to other event listings.
(The QST listing requires us to supply a city location and four freqs, which I would otherwise have preferred to leave out.)

Hello friends,

Part 1
New entry in the FM-32 Key Census Page.
I recently worked Lothar - DL1DXL on 40m, a very good bug operator.

We had a nice chat, we talked about bugs and sideswipers.

He is the happy owner of a FM-32 key, no serial number on it.

Thanks Loy/Lothar!
Part 2

Have a look at Martin's - G4ZXN latest creation: the Veroboard Cootie.

Congratulations Martin, this thing sounds great!

Keep up the good work mate.
Part 3

Please have a look at John's - 9V1VV SSN webpage:

Congratulations John, neat work and interesting information, looking forward to hearing some cootie sending from Singapore... Let's hope for better conditions.
Keep up the good work John and have fun on the air with those little gems.
Part 4

Mars rover, CW

I had a chance to visit JPL in Pasadena this week, and saw the replica Mars rover on its test range.
If it comes through, here is a picture of the famous "JPL" written in CW (from bottom row to top on the photo) on the wheel of the rover.

73, Darrel, aa7fv.



Hello Darrel and the group,
I didn't know about that Darrel, thanks so much for sharing the info and the picture, very interesting!

I must do the same with "SSN" on my lawn mower wheels.
73, Yann, F5LAW.


Hi Yann,

I was told the following: the Mars rover was built at JPL, by JPL engineers, for NASA.

They were forbidden from putting any "JPL" logo anywhere on the vehicle.

The holes in the wheels are put there so that, from photos of the tracks of the vehicle in the Martian dirt, it's possible to calibrate exactly how far the rover has traveled.

The JPL engineers came up with this way of getting "JPL" visible on Mars, in a way that the NASA managers would not recognize.

73, Darrel, aa7fv.

Have a nice day gents, BCNU

73, Yann, F5LAW.
