Slight upgrade to K3

I spent about 45 minutes this morning installing a KXV3A into my K3. This is the option that allows a second receive-only antenna and provides an IF output. My reason for adding it to the K3 has to do with the latter capability as I await the arrival of my Anan-10E from Apache Labs. As…

The storm that wasn't

By now, most of you have heard that, at least in the New Jersey area, "The Blizzard of 2015" has turned out to be a big bust. The forecasters were warning us of 18-24 inches (45-60 cm), plus. Instead what we actually received was about 4 inches (10 cm).

I am one of the ones who is not disappointed. I would much rather have the weatherman tell me I am going to get 24 inches of snow, and only get 4, as opposed to the other way around. Meteorology is an art, even to this day. To anyone who is forcing the weather people to eat crow today, I say, "Let's see YOU try it for a while!". I am hearing so many people say, "Oh yeah, I knew from the beginning it wasn't going to be that bad."  Yeah ..... right.

Listening to New England stations coming through Echolink on the local repeater, I understand they are getting hammered, as predicted. Stay safe, warm and dry, my friends.

Even though we didn't get the snow, we did get the cold and the winds. Not gale force winds, but when I was out there shoveling snow, I was chilled to the bone. And the whole time I was removing snow, I was dreaming of something like this:

Thanks to Sean KX9X for posting this.  Some portable outdoor QRP in a nice, warm sunny location is EXACTLY what the doctor ordered, right about now.

On a side note, the office was declared closed for the day last night, when the ominous forecast was still hovering over us. So when the snow stopped this afternoon, having some time available, I went out and switched the coax from the EDZ over to the W3EDP. Much to my relief, the W3EDP hears fine again! It loads up easily on every band and the KX3's auto tuner handles it with nary a whimper.

As it turns out, the coax problem on the W3EDP was entirely may fault. When I went to disconnect the coax from the balun at the end of the W3EDP, I noticed to my horror, that I had never sealed the connection. It's no wonder that water got in there. This time, I double coated the connection with tape, added some plumber's putty over that, and added a final layer of tape.  If the W3EDP plays as well as I think it will, I may just end up taking down the EDZ this Spring and keeping the W3EDP as my primary wire antenna.

It's been a while

It's been a while since I really made an effort to use the ol' Vibroplex.  I gave the contacts a decent cleaning today and gave it a whirl in a QSO with Art K8CIT. I don't think I sounded terrible - and I hope Art didn't think so either. I could use some more practise, though, and I will continue to use it more often.

I haven't run this piece in a long time. It's from my old webpage on how to adjust a bug:

Using a bug is a real fun part of using Morse Code.  Adjusting one properly so that it works right for you and doesn't frustrate the heck out of you is easy; if you take your time and work methodically. Refer to the photo below for reference.

The first thing you do is to back off all the adjusting screws quite a bit.  Not all the way; but far enough out so that everything is nowhere near being set.  Once that's done you want to adjust the action of the pendulum.  Unscrew "A" - this is the pivot point for the pendulum.  Slowly tighten it. You'll know you have it adjusted correctly when the pendulum moves from side to side freely with no binding; but, at the same time, you can move the finger pieces up and down with your fingers and feel very little or no play.

The next thing you want to do is to adjust screw "B".  Allow the pendulum to hit the damper.  Screw in "B" to the point where you can either see or just perceive the pendulum has touched the damper.  Stop there and secure the screw with the knurled lock nut.  It is important not to move the pendulum too far away from the damper or else you will not be able to reliably stop your "dits".

The next thing you want to do is adjust the  left trunnion screw -  D.  This will control the amount of side to side travel of the pendulum.  For smooth code this gap should be very small.  I take a piece of ordinary printer paper, fold it in half to double it and adjust the spacing so that the paper will just slip between the point of the screw and the pendulum.  This results in a very small amount of side to side travel.  The end result is a nice and clean transition between "dits" and "dahs".  I do the same thing for the amount of spacing for the "dah" contact at C.  I turn that trunnion screw in so that the paper slips in the gap easily with no binding, then I lock the set screw in place to keep the setting.

The next thing you want to do is adjust the "dits" making part of your bug.  This is done by adjusting "E".  When "E" is adjusted correctly, you should be able to swing the pendulum to make "dits"; and get 10 to 15 "dits" before the pendulum dampens out and comes to a rest.

"F" controls the tension of the "dit" action.  I find it best to tension the spring about half way.  Hopefully, if you follow this guide and play around a little bit and experiment, you will find the "sweet spot" that will allow you to send really glassy smooth Morse Code.

Sending with a Bug is just as much fun as sending with a keyer and paddles.  However, sending with a Bug allows you to add a little personality.  Listening to CW sent with a keyer sounds sterile compared to that sent with a Bug.

If you need to slow down the speed of your Bug to a point that's even slower than what you can get with the weight(s) positioned all the way to the end of the pendulum, then clip a clothes pin or a few alligator clips to the end of the pendulum.  This will slow down a Bug to an effective speed as low as 13 words per minute or so.

In my opinion, you know that your bug is adjusted properly when you can send characters like X, Y, Q, C, F and L with little effort, and they sound good - or at least recognizable in my case!

Here's a great video that shows you how to do it, also:

472kHz WSPR

I have been using 5mW ERP and the earth-electrode "antenna" all day.  Best spots of me today have been from stations that have copied me before such as G3WCB (101km) and G8HUH (250km). It will soon be time to change antennas.

10m USA WSPR spots today

KE6BID (5295km) was the first USA station to spot my 500mW WSPR beacon today at 1300z. As I write this at 1624z, there are plenty of USA stations spotting me still.

UPDATE 1920z:   It looks like W9ZOC (6259km) was the last USA station to spot my 10m 500mW WSPR beacon at 1818z. It is over an hour since the last USA 10m spot so it is unlikely that there will be others now.

K1N, información desde Gran Inagua

K1N Team / 27 enero 2015

"Electra" está anclado en el lado sur de Gran Inagua, 170 millas náuticas al norte de Navassa . El tiempo se está deteriorando lentamente con vientos de 15 nudos (a las 09:00 AM). Se espera que los vientos aumenten durante los próximos tres días a 25-30 nudos. Nos moveremos hoy para encontrar un lugar para echar el ancla más cómodo adelantándonos a los vientos fuertes.

La previsión para el período del 30 enero al 3 febrero no es favorable. Se pronostican vientos en el Paso de los Vientos (entre Cuba y Haití) que comenzarán soplando desde el noreste a 20 nudos, aumentando de 25 a 30 nudos el día 31. Los vientos se mantendrán fuertes hasta el 2 de febrero. 

Alrededor de Navassa, los vientos tenderán a ser más ligeros, alrededor de 15 nudos, la tarde del 31 de enero y el 1 de febrero. (Parece que Navassa es un tanto a la sombra del viento gracias a las montañas de Haití).

El 2-3 de febrero se prevé vientos muy ligeros alrededor de Navassa, pero un fuerte oleaje se iniciará desde el sur-este, llegando a 2,5 metros el 3 de febrero. A causa de las olas, es probable que sólo tengamos el 1 y 2 de febrero para descargar equipos y los suministros.

Nuestro plan actual es la siguiente:

Tenemos la intención de navegar desde Gran Inagua la tarde del 30 de enero con viento de 20 nudos del nordeste. Los vientos soplarán en su mayoría de  popa, que, esperamos, hará que las condiciones sean tolerables. Vamos a bordear el extremo occidental de Haití y esperamos quedar alojados a sotavento de la isla durante la noche del 30 y la mayor parte del 31, cuando los vientos lleguen a 30 nudos en el Paso de los Vientos. Luego nos acercaremos a Navassa desde el este hacia el norte y revisaremos las condiciones en la isla. Con suerte, la bahía de Lulu estará en buenas condiciones y podremos pasar la noche allí. Tenemos la intención de comenzar a cargar y transportar todo la tarde del 31 de enero y durante el día el 01 de febrero .

Fredbox derivatives

Since my original Fredbox 2m AM design, a number of derivatives have been designed and built around the world. This is what our hobby is all about. Although the original Fredbox worked well and its results surprised me, it was always ripe for further developments, which is healthy. My Sixbox was a 6m version and at some point, when fitter, I'd like to make a simple 10m AM version for local natters.

See https://sites.google.com/site/g3xbmqrp3/vuhf/fredbox for the original Fredbox. Click on the schematic to enlarge. Other derivative ideas are on my website www.g3xbm.co.uk.   By the way, it got its name from Fred G8BWI who was a disabled local in the Cambridge area back in the 1970s. Fred was a regular contact and he could talk for hours and hours and hours and hours zzzzzzzzzzz. RIP Fred.

Stroke update

Last year I was expecting to be fully back to my old self well before now. As it is, I am still some way from that position.

Overall, I think I am still improving, but the big leaps I was expecting don't seem to be happening. Perhaps I should be satisfied with slow, small, moderate steps?  

I still feel as if I am living in a bit of a dream world, I still feel drunk when walking (feel giddy), still tire easily, and drinking thin liquids is still not easy.

Overall, I am getting slowly better, but perhaps I should expect to be left with a level of disability and will be pleasantly surprised when I get fully fit again. Perhaps my expectations were unrealistic? Whatever, I am not giving up: I want my "old self" back again this year.

At the moment I still feel unable to do field work, climb ladders (for antenna work)  or use a soldering iron. With time, this will improve.

Sunspots up again

Sunspot number today has risen yet again. It is 140 today. 10m is expected to be "good".

4X1RF (3519km) was copying my 10m 500mW WSPR beacon at 0924z. I remain hopeful of greater DX this morning. 10m should certainly open to North America after lunch. This happens on most days.

Solar data on blog not updating??

For about a month or longer I have noticed the the solar data chart that is on my blog is not always updating to the current day. Sometimes the information is 3 or more days old, I thought it was just my blog and was not refreshing properly but I have also noticed on other blogs the same thing happening.  I sent Paul N0NBH an email regarding this today. I like this little app on the blog as it's a nice fast check of conditions for both me and my readers. Having said that it's also true and I have experienced it myself……and that is don't always go by the solar data get on the air you may be surprised.

433MHz AM modules - G6ALB progress

G6ALB has reported some progress in his tests using 433MHz AM modules, although it looks like an external linear audio transistor stage may be necessary to get best AM (voice) sensitivity from the super-regen detector. On TX he is getting 10dBm from the TX module at 5V (more with higher supply voltages) although the mod seems to be a mix of AM and FM. Our first "DX" test will probably be from G6ALB to me using the voice modulated TX module. I'll receive Andrew on my FT817ND initially. When the super-regen RX is sensitive with speech I'll try to receive him with that. Super-regens should be sensitive on AM, but are usually poor NBFM detectors.  We are about 3km apart and both have V2000 verticals externally mounted. At 70cms these have gain.

Andrew has ordered 5  pairs of 433MHz AM modules (TX as well as RX) for not much more than £2 total from China. This makes each TX/RX pair very inexpensive. It amazes me that they can make these so inexpensively. I hope G6ALB succeeds in this venture. It would be good to be able to communicate with him using a really low cost 70cm transceiver. I expect Andrew will write up his results in an article for a UK magazine later.

It seems entirely possible that a complete 70cm AM transceiver can be made for just a few pounds based on these low cost 433MHz AM modules.

29MHz AM

The 29-29.1MHz sub-band continues to be the best place to find HF AM. This is the HF band with most space, although there are AM enthusiasts on 160m and other bands. When these bands are not busy AM has its place.

When 10m goes "off the boil" 29MHz AM will be ideal for local nets with very simple gear. Ranges are fine for local nets. Also there is a ready supply of ex-CB kit around, although making a wholly homebrew QRP rig for 29MHz AM is a nice group project. There are some ideas for starters on my main website.

As an example of how effective 10m AM can be see http://www.macnaughtonart.com/10metlog-ss24.htm .

Sunspots and 10m - Jan 28th 2015

Sunspot number continues to climb and is 119 at present. For the first time in some while, 10m propagation is forecast to be "good". LZ1OI (2153km) has spotted my 10m 500mW WSPR beacon 10 times this morning already. As I write this it is 1046z.

Today could be a good 10m day.

UPDATE 2215z:   Now QRT on 10m WSPR  Although the band did open to the USA after lunch, it was a rather disappointing day on 10m WSPR for me.

The first USA spot of my 10m 500mW WSPR was K9AN (6505km) at 1352z. The last USA spot was W3CSW (5886km) at 1804z. It is still possible later USA spots may happen, but it is now over an hour, so unlikely.
