What is the ideal code speed?

Let me make it clear from the outset. I am no expert at CW. I guess I can comfortably work at around 18 WPM during rag chews and up to about 30 WPM at a push during contests.

I know this a futile question to ask, but it might still be worthwhile considering.

This morning I worked Philippe V5/F5JWH with CW on 40 metres. Philippe was using a straight key and exchanged SKCC numbers (pretty rare thing in this part of the world). He was sending fairly slow well spaced CW and it was real easy to follow the QSO without the need to revert to pencil and paper. The QSO was certainly more memorable and enjoyable than most of the high speed DX “599 73 TU” type of exchange we normally engage in.

This got me thinking. Why do we constantly try and push the envelope with regards to our operating speed on CW? Maybe we should consider slowing down once in a while. Just maybe we could attract newcomers to this magic mode in the process.

QRP vs Fly fishing

The following is quoted from the SARL forum.
Written by Denis ZR6DNS


Fly-fishing is using tiny little hooks decorated to look like all manner of insects instead of bait. One casts the line, which is quite heavy as this tiny little decorated hook is too light to cast, and not a sinker to pull the line out after it. Some of these decorated hooks float on the surface and look much like any of the flying insects one finds around heavens waters. Others try to look like these insects in their nymph stage and are played along under water as if alive. They are, for convenience and brevity all called flies. They are never carried in the creel but rather hooked into the fisherman's hat or sometimes on a piece of lambs fleece pinned onto the shirt or a special waistcoat.

Ones creel might hold a flask of whisky but always an item like a little hammer called the priest. The whisky is so one does not feel too cruel about performing the last rights with this priest on these noble creatures.

The object of this whole procedure is to enjoy the peace and tranquillity of nature at its best, usually early morning or evening. It is called fishing because occasionally, and perhaps quite by accident, a trout mistakes this attempt to mimic nature and gets hooked. Often the fly-fisher will then gently manoeuvre the unfortunate fish to the bank, and without even removing it from the water, disengage the hook from its leathery mouth and shoo the fish away. After all; catching a trout, performing the last rights (along with a suitable dram of the water of life) and placing it in your creel could result in the early termination of this most serene experience. That is to say; reaching your bag limit too soon.

Rather like reading a good book; you want to know what happens in the end but you don't want the story to finish.

It is a pastime not understood by many, as is the case with CW QRP RaDAR. 
 

I thought the QRP crowds were weird, but now that someone has explained the art of fly fishing so well I am starting to wonder.

Both activities require:

The lightest tackle to catch an unsuspecting victim.

Require a fair amount of patience and success is not assured.

The differences are:

With QRP it is not (normally) required to use a priest to dispense the last rights.

With QRP we certainly would not place the whiskey in a smelly fish creel and then carry our equipment on our heads or pinned to our clothing.

ZS-WAGS Garmin GPX overlay file

I produced a small Garmin .gpx file that might be of value to those amateurs involved with the ZS-WAGS award.

The file can be down loaded from here:

http://myhome.mweb.co.za/~pierrevd/ZS-WAGS.gpx

This file must then be saved to your PC as e.g. “ZS-WAGS.gpx” in some convenient place such as My Documents.

When using the Garmin Map Source program this file can be opened, it will then result in 83 Magenta rectangles being drawn as an overlay on any of the map files that the user uses. The user may also consider to set the default position display to Maiden Head (use Edit/Preferences/Position/Grid select  Maidenhead Grid) The Maidenhead Grid locator below the cursor position will then be visible on the bottom left of display.

The same .gpx file can be up-loaded to a Garmin GPS. This will draw the Magenta boxes around all the 83 ZS-WAGS grid squares as an overlay. This makes it easy to identify that a grid boundary is being approached on the moving map display whilst mobile. The GPS can also normally be also set up to display Maidenhead locator if so desired

Hope this is of some value.

QRP contests - Preferred modes?

Well the provisional results for the QRP Winter contest has been released and I am pleased to see that it appears as if there has been quite a few newcomers that took part in the event.

It was even more pleasing to see that CW was very well supported. Sure hope this trend will continue.

I made almost all my CW QSOs with the HB-1a transceiver. The amount of pleasure to work some distant station using some 4 watts with a tiny transceiver barely the size of a paperback that in turn is powered by a few penlight batteries is just magical. Even after all these years of me playing with QRP it still blows my hair back!

Most of the QRP contesters used SSB and a few used both SSB and CW, with the odd one that used CW only.

That got me wondering, what transpires elsewhere in the world? I am under the impression that CW is used almost exclusively in QRP contests. Is that so? Or is SSB used. Most of the results I see from North America seem to be CW only events.

Extreme 6M mobile station:

I came across the following web site:

http://k7xc.tripod.com/6mkwrover/index.html

That is one serious 6M grid activator.

What is in your lunch box today?

This is a healthy alternative …..

The URL below points to the site of Hanz Busch W1JSB.

This is QRP at its best.

BTW This is the same Hanz that accompanies Jim W1PID, on most of his adventures I wrote about recently.

Amateur Radio and the Internet

I have been a Radio Amateur since 1975 and prior to that I was a very keen SWL for quite a few years. 36 years later I am still very interested in this great hobby.

I think to a great extend it is due to the internet and what it has done for us as Radio Amateurs. I am referring to such things as QRZ.com, the DX Clusters (DX Summit), electronic QSL facilities such as LoTW and E-QSL, Online skimmers, the Reverse beacon networks, the abundance of HAM related web sites and the Blog sites of many interesting individuals.

There are few blog sites that I follow with great interest on a regular basis. Most of those I find most interesting share in similar interests as my own. That being CW, QRP, homebrew and kit built equipment and operating from some outdoors away from home venue.

This has led me to discover a few amateurs that inspire me and are listed below.  Some with blog sites some without, but interesting bits of info can be found them by using Google.

There are many more sites / amateurs I find that inspire me, this is just the ones that stand out most for now. Maybe the readers of this blog will also find them as interesting.

Errecting antennas in trees

Using a sling shot (Kettie)

I have used a sling shot on many occasions with great success and it works very well. The biggest disadvantage is that one needs to have available (carry) a sling shot and fairly heavy fishing sinker some fairly thin mono filament fishing line and a spooling device.

The weight needs to be fairly heavy so as to ensure an unhindered decent through the branches and leaves. The lead weight (fishing sinker) I use weighs 85 grams. The lead weight and line is shot over the targeted tree limb using the sling shot and the weight is allowed to descend to the ground.

The weight is the removed and the antenna support line is attached to the thin mono filament. The sturdier antenna support line is then pulled over the tree limb ready to attach to the antenna center insulator.

Using the tree arbors underhand toss

The above method is yet untried by me, but certainly has the potential to work very well. The weight used is normally fairly substantial. Geoff ZS6GRL tells me he uses a 400 gram weight made up out of fishing sinkers.

The tree arbors normally use a custom made soft leather bag filled with lead shot, I guess it will minimize the damage if it falls on something it was not meant to fall on?. I notice some radio amateurs use a small plastic water/soda bottle partly filled with water as the weight.

The action of how to launch the weight is best described as follows:

"The secret is to throw underhand, starting off with a gentle to and fro motion and then letting rip."

The following You Tube video shows the action nicely.
