GB4LBC Special Event Station

It been a real pleasure to be operating the GB4LBC special event station for SOS radio week today. With just a long wire and 100w we had our own little pile up which lasted pretty much all day.

The station will be up and running again tomorrow on 40m and hopefully will be just as popular. The Workington and district club (MX0WRC) is operating 3 of the 4 stations in Cumbria

GB1LBC – Silloth
GB2LBC – Workington
GB4LBC – St Bees
GB5LBC – Barrow in Furness

GB5LBC is operated by our friends at Furness ARS and we managed to have a quick QSO during the pile up

SOS Radio Week

This year Workington and District are joining up with Barrow in Furness club to extend the amount of stations we activate.image We are operating from Silloth GB1LBC, Workington GB2LBC, St Bess GB4LBC and Barrow GB5LBC lifeboat stations from the 21st to the 29th January in a relaxed style. hopefully making htis years SOS radio week a bigger event locally.

The purpose of our time on the air as special event stations is to promote the RNLI  as a charity, something that costs £300,000 a day to run!

St Bees will only be running at the weekends and We are looking to be on mainly 40m and 80m but the Cobwebb is coming with me so there is a possibility of something on the higher bands but it really depends on the weather as high winds will certainly destroy it.

I hope to work as many as possible in between cups of tea and choccy biccies and if you would like to make a donation then it would be really appreciated. Keep an eye out on the status monitors to see when we’re up and running.

JT65HF problems

There re just a ton of data modes you can play with and this morning was the turn of JT65-HF to be on my screen. I’d installed it quite a while ago and not used it for some months but I thought I could do with giving it a quick run through to remind myself of the protocols in case we use it on the SOS radio week operations (as GB4LBC for St Bees lifeboat station).

Time is very important with JT65 and a few other modes and I’ve never been a big fan of windows time setting utility. It never seems to be right and there is always a problem with either this or that. I use Dimension 4 on XP machines and it works very well. Under Windows 7 you have to remember to run it as an administrator so I suspect the same will be true for Vista. there seemed to be a bit of a conflict going on on my puny little computer so I had to reinstall JT65-HF and only then did it start to decode the received signals.

I took the opportunity to use my stealth antenna (A Watson 80 plus 2 dipole – which is really only good for 20m here) and immediately got a contact with DG8RW & W3PV with 15 watts. JT65-HFI had a bit of trouble with the first contact as he couldn’t copy my signal report for a while and I had to resend it quite a few times before he got it. Eventually we got a QSO together and that was pretty pleasing.

So I’ve got my hands dirty again with JT65 and whilst its not the most interactive of modes it reinforces the fact that SSB is inefficient in comparison as I doubt I’d have got where I did with 15 watts and a loft mounted antenna. Still, it was a nice distraction from what I should have been doing. That was to be revising for an exam on Tuesday. Nothing exciting, a professional exam and much less enjoyable that playing with radios.

AO-07 on a Sunday evening

After a hour or so of the JT-65 used frequencies (note – not allocated but generally used frequencies) being covered in RTTY I decided not to bother trying to have a QSO using that mode. It also helped that the JT-65 programme kept crashing on my struggling net top.

I thought I’d try and listen out for the ISS if it was passing me by and using HamSatDroid on my trusty phone I was presented with a big fat ‘not today you won’t’.  I remembered that I hadn’t updated the Keplerian data before checking the passes so I did and the programme defaults to the first on the list. AO-07. It showed that it was due to make a pass in about an hour. Taken from HamSatDroid Website (http://sites.google.com/site/hamsatdroid/home)With this opportunity I assembled my Sotabeams SB270 and checked to see if the pass was easily visible from my house, i.e. from about SW to roughly NNE and luckily it was so I thought this would be an opportunity to taken.

Bearing in mind it was dark at this time and my decking needs a good coat of ‘taking down and rebuilding thanks to Story homes’ I pointed the antenna skyward and was met with a crackly warbly of ‘CQ satellite’ from a German station. he called CQ for the complete pass and I didn’t hear a single response to his calling. At this point I wish I had a duplexer connected to the antenna and a steady tripod as well as a handy lightweight rotator to help with the pass as this was too good an opportunity to miss. Alas I had none of the above and the station went unanswered. A 2m / 70cm duplexer is now on the shopping list as the chance of me being able to spend some time making a rotator is fairly small. Perhaps a larger one will come available at a Hamfest or eBay.

VHF is by no means easy at my QTH but there seem to be opportunities and its probably about time I explored a few of them

RTTY QSO’s everywhere

It must be the weekend, the bands are just packed with RTTY noises. RTTY is just one of those modes that refuses to go away and thankfully my rig is handy at muting out the warbles so it doesn’t drive you insane.

RTTY

Contests are really not my thing but they do give you opportunities that might not be available at other times in the calendar. For me it was a new one VP9 or Bermuda in English and a welcome break from revision for my MSc exams

The screenshot above is just a taste of what was taking over the lower portion of the 20m band. I did actually fancy a few PSK-31 QSO’s but glad I ended up giving RTTY a go. probably not the most conversational of the data modes where you actually type in real time but still nice to get the VP9 in the log.
