Tis the season….for 70MHz FM!

Not much from me during the last few weeks. A busy time at work, with three new websites going live in the space of two weeks – so most brain cycles going towards that during the lunchtimes that I normally use for a bit of blogging!

Over the last couple of weeks, I’ve been turning the 70MHz FM rig on a bit more often. I realise that 70MHz FM is a winter band/mode for me. During the summer, the antenna is usually connected up to the CW/SSB rig in case of a bit of Sporadic E. With the chances of that significantly lower now, I’ve been enjoying some more local contacts.

Good to work Geoff, G3NPI near Buckingham last weekend and to hear how active the band is on FM now. Clearly the combination of PMR kit and imports from the Chinese market has been a popular one. Keen to work a few people using the new Wouxun Dual Band handhelds when it’s warm enough to go out portable again.

This morning I had a nice QSO with Ted G3XUX/P near Winchester. I worked Ted through the MB7FM parrot, but we were also able to exchange signals directly, which is nice over the 40-45 mile or so path between us. Listening to MB7FM whilst I was doing a few jobs showed several other stations active, so if you have 70MHz FM, it’s well worth switching the gear on and making some calls as you can.

ARRL 10m contest part 1

First of all thanks all that replied to my previous post and send me best wishes and health I really appreciated it. Actually I don’t feel that ill when I keep quiet. But from what I heard Pneumonia can be very treacherous and I don’t want to end at the hospital. So, I heated up the radioshack and did a few hours of DX on 10m today in the ARRL contest. So far not too bad. I worked VK as new DXCC on 10m SSB (VK6IR had the honor). And of course lot’s of other nice DXCCs. Actually when the USA/Canada came in strong the band was that crowded I decided to call CQ up in the 28.800-815 to take some rest and was surprised that there actually was response. I was even spotted on the DX cluster! Band closed very early but I already stopped at 15:15 UTC as my little QRP Anneli was awake from her afternoon nappy and I was very tired as well. Tomorrow is a new day with new chances.

1200+ Mile Contact on 10 Meter Handheld

As Hams, we know the phrase “A little goes a long way” is very true in Ham Radio. Anyone working QRP can tell you that. There are people that have worked the other side of the planet with just a few watts. I worked Japan once with 5 watts with Grayline. But check out this video of 1200+ mile contact on a handheld.I didn’t even know they made 10 meter handhelds. But we can see one here in the video. As well as making that contact with just 5 watts of power. Not too shabby at all. I say keep this video handy for recruitment. This shows how radio can work.

73.

Handiham World for 07 December 2011

Welcome to Handiham World!

Heathkit HM-102 SWR/Wattmeter poses with Icom gear at WA0TDA.
Image: A venerable and still useful Heathkit HM-102 SWR/Wattmeter poses proudly amid my Icom gear. These days, it is an occasional test instrument rather than a device that is used every day. 
Kits – electronic kits – have always been a part of my ham radio world since I was licensed as a teenager in the late 1960’s.  Kits were around before that, and hearken back to the long tradition of amateur radio operators building their own equipment.  While not the same as designing and building one’s own gear from scratch, kits do allow those who want to feel more vested in their radio equipment to enjoy the “hands-on” experience of assembling the radio and learning more about the layout and circuitry than if they had simply unpacked a new rig and put it on the air.  I can’t think of a time when I haven’t owned at least several kits.  Some of them have been transceivers or transmitters, while others have been accessories or test gear. 
The motivation for owning kits has changed through the years.  Back in 1967, when I got my Novice ticket, and a year later, when I upgraded to General, it was more important to me to find affordable gear so that I could just get on the air. Kits like the Knight T-60 transmitter filled the bill. Paired with a Lafayette receiver that drifted like a rowboat in a hurricane until it warmed up, this little station was the source of more on the air fun than you could ever imagine. I was already familiar with Knight-Kits, having built a two tube regenerative receiver, the “Span Master”, while in high school. When I made the inevitable move to SSB, the Heathkit HW-100 was the kit of choice. It’s 20 tube circuit was challenging to assemble, but I laid everything out on our family’s ping-pong table in the basement and just followed the directions.  It worked the first time, and after alignment and installation of the case, provided my first really solid experience with phone operation, though I had plenty of fun working DX on CW. 
Over the years I built other kits, some of which were test gear that I still own and occasionally use today. Some kits, like a Heathkit SB-201 linear amplifier, were purchased assembled on the used market.  Later on I donated that amp to Handihams, having decided that high power wasn’t really all that fun or useful. There are plenty of good used radios and accessories on the market, originally built from kits but working well today. 
Today’s kit builder is motivated less by the need for economy and more by the desire to experience the fun of putting some of one’s own effort into the station equipment.  However, there is an important new niche in amateur radio kits – that of simply offering equipment that isn’t available any other way.  A third development is the evolution of superior kit radios that rival or best the already-assembled competition!  Cost does not necessarily enter into the decision making for any of these three kit builders.  
I was pleasantly surprised to hear from a group of kit builders here in the Midwest.  The Four State QRP Group has a kit building service and has built kits for hams who are blind or who just can’t see well enough to complete a kit themselves. They do not charge for their service and would like to offer their services to our members.  This is an option for those who cannot build a kit on their own but who would like to experience the fun of operating with a transmitter that would not otherwise be available to them. A link to their website follows after my identification. 
But what about kits that can be assembled by blind hams?  One inquiry that intrigued me recently came from K9EYE, who would like to find a kit for a QRP A.M. transmitter that is possible to assemble with minimal soldering.  Pierre and I both remember as kids having electronics kits or “labs” that were designed to allow for experimentation with a variety of circuits.  Since they were designed with clip and plug connectors, they lent themselves to assembly by just about anyone.  For some reason you couldn’t trust kids with hot soldering irons but wood burning sets seemed to be okay.  Anyway, we all survived to tell about it today!  But we would like to find some blind-friendly kits.  If anyone has sources or ideas, please let us know.  
For Handiham World, I’m…

Todays activity

I actually put the old 6 elem. logcell together for the upcoming 10m contest. Never expected that I would actually use it again and forgot to mark bits and pieces. But overall putting it together went smooth.  Unfortenately just when I was ready to get it up the small mast it there was a very heavy storm arriving with thunder, lightning, rain and hail. So, I hope to continue Saturday morning if weather and time alows. Some specs of this antenna. 4 elements fed, gain about 11dBi, front to back >30dB, front to side approx 25dB. Unfortenately I don’t have a heigh mast to put it on. So the specs will not be that good as on say 12 Mtr height. I think even on a low mast it will outperform my multiband vertical on 10m. We will see this weekend.
