LIDS_CW

Whilst twittering / tweeting / wasting time on twitter (delete as applicable) I came across a group @lids_cw . This is an informal twitter based group of CW and low impact data mode fans in the UK that seem to have their heads screwed on. The idea behind it is that the group encourages general radio chit chat then suckers you into having a go at CW.

Morse is not something I decided I wanted to do when I started out in radio, Hence the G7 callsign (For those unsure, G7′s in the 1990′s were VHF only because we couldn’t be bothered with CW. Hence the 19th Century rules at the time kept us away from HF as were weren’t proper or some such daftness). But over the years I’ve hankered after at least one QSO in CW. I’m only browsing, for research purposes, I wont be giving up VHF officer!

Sunday at 16:00hrs GMT see’s their net on 40m. I listened in and attempted to decode what was beeping through the speaker an got the occasional character. I cheated a bit and used HRD to decode some more of the text and fill in the gaps. It wasn’t until I let slip on Twitter I was listening in I heard my callsign being called by MW0IAN. Fortunately I had no way of returning the call (otherwise we might still be at it exchanging signal reports now!).

For those of us who struggle with CW but are too scared to admit it, there are others like you. For those of you who had the 5wpm RSGB cassette and never got further than ‘it’,’meant’,’mine’ and ‘nineteen’ but fancy spending hours listening to bleeps but secretly want to have a go. Watch out LIDS  or Less Involved Data Society as it’s known will get you. Keyer at the ready for next Sunday. Snails will be faster.

Christmas Cumulative’s

 

So Christmas has left us again. this time I’ll be glad to see the back of it after being and bit part player in the events in George Square, Glasgow just before Christmas and spending most of the subsequent days either laid up in bed or coughing and Christmas Cumlatives  2014 144Mhzspluttering my way round the place.

On a lighter note the days between Christmas and New Year led themselves nicely to The RSGB Christmas Cumulative VHF series. A Contest run between the 26th and 29th December that gets me out of the house and either into the wilds of Cumbria at this time of year, or as it happened yesterday one of the clearest, crispest days we’ve had in a long time.

The contest is only a couple of hours long and the choice of band(s) is up to you. I thought it would be a good opportunity to take my dual band 2m and 70cm antenna that I got from Nuxcom in the summer. The antenna is a tad fiddly to construct in the field as the elements wander with the slightest touch but the lack of wind helped there.

The rig was the usual FT-857 that I have had on loan from the club for a while now that gives me my choice of 10w out on the VHF bands.

The map above shows my results. ODX was 450 miles to G7RAU, which equals my best to date. Other bigger stations will have undoubtedly made more miles but it’s not all about the DX. Hopefully I will get the chance to get out and about on the UKAC evenings as well as the back end of the year was a bit of a non event for me. Here’s an obligatory view form the ‘shack’ and dual band antenna (Here’s a link to the original site for the antenna)

GB4LBC – SOS Radio Week

Its nearly that time of year again when St Bees Lifeboat station becomes a mass of cables and slightly cold and damp radio amateurs. All in the name of SOS Radio Week.

The week doesn’t actually start until January but in the interests of being on time I applied for the GB4LBC NoV before Christmas this year. Ofcom did their bit in only a day or so and the email hit my inbox yesterday.

We haven’t made too many plans yet but the two weekends we’ll be activating the site (along with the usual suspects from Workington & Furness clubs doing their bit from Silloth to Barrow) are published as those falling between the 24th Jan and 1st Feb.  Last year we had a bit of bother with some bad weather. Here’s a reminder……blue sky not always available (the lifeboat station is the white building on the right in the distance)

Its worth mentioning at this point that the week is both an awareness special event and a fundraiser. The RNLI relies of volunteers to man the boats and Joe Public for donations. Our own volunteers are trained to go out in just about all weathers as well as doing a day job. Cumbria Crack had a cracking photo of it being launched in a relatively boisterous sea. The contraption behind the boat is a submersible tractor that lunches the RIB.

DStar and Digital Networks

If your pockets are deep and your mind open then DStar offers some useful opportunities to connect to other amateurs via a very robust network. I on the other hand am a cheapskate with very shallow pockets and a healthy distrust of proprietary stuff. So how does one get involved in a changing view of amateur radio? There seem to be a few options that are more that dongles for your PC.

FreeDV is one way. It promises a way of connecting up your existing analogue radio to the digital networks. A very brief look at it this afternoon gave the impression that if there was a signal to be heard (On 14.236Mhz) then it would decode it and display the QSO on the screen. Trouble is there where no HF signals.

DV3000 bridge is another way to connect your radio to and existing set up (Analogue VHF)

Jonathan Naylor, G4KLX also has spawned a range of hardware and software that makes use of digital voice that appears through the link.

All these little bits of knowledge came from an a hour or so when the kids were at their quietest (which is not often) so there’s clearly a bit to learn. I hadn’t paid much attention to DStar or its friends as at face value it was asking me to buy more stuff at £300+ . That was a turn off. But if there are options at a lower price point then I could be persuaded to join in the digital voice game.

SatNOGS

I remember reading something about this on the Southgate ARC news a while ago. When I tried to find it I couldn’t. Thanks to Hackaday.io I found it again.

So what is it. The website has some big ideas on it but, to me it is a homebrew, simple Az El rotator using open source software and 3D printed parts. Something that, funding willing, I will be able to do over the winter. Info on availability seems a bit scarce but I’ve emailed regarding PCB’s.

Here’s a few links and a video

Ouch and PortableSDR

Two things have happened over the last week. The first was that after what must be 10 years I had a decent crash on my mountain bike. Nothing too bad, just a reminder that I’m not 16 any more and that duckboards have 2 parts. One part grippy, one part slippy. The grippy bit is for the tyres not hands, kness, elbows and shoulders. The slippy bits are not for tyres. Enough of that though.

This forced lay off has had me googling rather than building stuff (that occasionally works) and I found what looks like a nice idea. From the video it looks like a simple, portable qrp hf transceiver. There isn’t much detail on the functionality but a quick dig revealed gerbers etc so a build-it-yourself could be on the cards. Without further ado, take it away Mr Colton

 

There’s a bit more detail here a the hackaday.io project page and a block diagram below

Ever wondered what I&Q are?

I was after a really good explanation of what the I & Q were when talking about SDR. These are better tan anything I could come up with. Thanks W2AEW!

Mini WSPR

So it works then. Mini WSPR’ing with the U3 on 20m with an indoor 1.5m whip antenna. Who said ham radio needs big stuff.

Echolink node update

Well the node is up and seems to be running reasonably well. The software is reporting distortion on the input but I think that is more to do with the close rf during testing. There are now some isolating transformers and a resistor in series to knock back a bit of signal and it seems to be ok when I connect through the web interface. Perhaps some other measures might help. Its still running on vox but until I can work out how to do the ptt easily I’ll stick with that.

I’ll leave it on for a while and see what I get back from the locals. Here’s a reminder of the details

Callsign – MB7IAH-L

Node number – 243350

Freq – 144.9625 Mhz

CTCSS – 103.5Hz

Power – 1.6w (hold onto your rf hats!)

Antenna – 1/2 wave dipole

All powered by a Raspberry Pi, Svxlink and a Baofeng UV-5R.

Enjoy
