Commonwealth contest – and my QRPP contest QSO…
As readers of this blog will know, I’ve been letting HF and particularly HF contesting take a bit of a back seat recently. No particular reason, but it’s just one of those ebbs and flows in my interests in the hobby – it’s happened before and I’m sure it will happen again.Last weekend was the RSGB’s Commonwealth Contest, often known as BERU. This contest is quite an individual one and one that you either love or hate. Anyway, that’s by-the-by, I love it and many of my Canadian friends, especially John, VE3EJ take part in it, so I always like to support their activity.I found a few minutes on Saturday evening to make some QSOs, mostly on 7MHz, where I worked John VE3EJ as well as a handful of others including 8P9AA, VY2SS, VE3JM, VO1TA and ZC4LI. I half intended to look at sunrise the next morning, but didn’t get around to it.And then my QRPP contact. QRPP is very low power – generally considered to be less than one watt. On Tuesday evening, I’d heard someone mention that it was one of the 80m CW Cumulative Contests. I tuned around quickly to see who was on and the very loudest signal was John, G3VPW who is about 3 miles from here in a village to the south of us. John was about 40db over 9! I turned the rig down to as little power as I could manage, around 100mw. Although it took me a few calls, I worked John – probably my lowest ever powered contact on HF!
70MHz update: And MB7FM back on air
Last evening was a momentous one for me on 70MHz! I popped into the shack after I’d got in from work and switched the rigs on, including the 70MHz FM rig. Andy, G6REG/M called CQ on 70.450MHz and I answered him.
Andy was about 12 miles away on the edge of Oxford and we had a great QSO as he drove down the A420 towards me. Then it struck me! By the time he got to the roundaboout just to the south of me, he was about a couple of miles away from me.
Quickly, I got the Wouxun 70MHz handheld out and called him! He heard me, despite the handheld being in the shack. We did a couple of overs on the handheld as Andy headed west, out to a distance of 2 or 3 miles. Signals were still S9. So that was great! I knew the Wouxun worked well, especially with the Garex Flexwhip, but I hadn’t actually had a contact with it. Thanks Andy! Hopefully now that the weather is improving, I will be able to make some QSOs with the Wouxun from various high spots.
And the other thing that came out of last evening’s 70MHz activity was that the Tring ‘parrot’, MB7FM is back on air. It vanished a few weeks ago as you may remember but it’s great to hear it back in service.
March 144/432MHz contest and a special mention to IS0BSR
Last weekend was busy, but I managed a few minutes on Sunday morning to listen to 144/432MHz and make a few QSOs during the contest. I had forgotten that it was a European co-ordinated contest, so there was plenty of activity from all over EU and conditions were quite good.
My best QSOs were F5OOM/P in JN38 and DF5GZ/P in JN47 on 144MHz. F1ISM was the best DX on 432MHz from JN09. But around 0800z, I was tuning up and down the band and I heard a great meteor burst from IS0BSR – I called him but sadly the burst wasn’t long enough!
However, this evening, I e-mailled Marco, IS0BSR to let him know that I heard him and he sent me a link to this great video of his contest activity from the weekend! Fascinating to see the station that allowed me to hear his 144MHz signals all the way from Sardinia!
VHF/UHF Tropo
With the high pressure over the last couple of days, conditions have been good on VHF/UHF. The only chance I’ve had to operate has been whilst I’ve been mobile, but there have still been interesting things to hear.
Listening on 145.650 last night as I was driving home, I could hear ON0WV weakly but clearly. This morning, the Bedford repeater, GB3BF was easily audible in Oxfordshire on 145.7875. I gather that there was good activity on SSB last night on 144MHz with DK1CO (JO63) and a number of Dutch stations being worked.
Albrecht AE2990AFS – 24/28MHz portable
Thanks to Julian, G4ILO for drawing my attention to the Albrecht AE2990AFS portable rig on his blog.
As Julian describes, the rig is actually a multimode, multistandard CB rig, but it can be very readily converted for amateur bands use.
With solar activity starting to improve, it seems, 24 and 28MHz should become much more interesting and full of possibilities. Of course, low power and simple antennas will not always get through, but as conditions improve, so will your chances.
I was part of the team that operated from the Comoros islands as D68C back in 2001 and for many of the operators, one of the memorable QSOs that we had was with a portable station in California who was using a handheld 28MHz radio at a bus stop! And one solar cycle before that, I remember listening to mobile stations driving around Tokyo, Japan whilst I was using converted CB rig with a 28MHz vertical in the loft.
As I’ve already got an FT817 it would be hard to justify spending money on the Albrecht, but it certainly looks like a lot of fun and I can imagine them becoming popular.
And now it’s off again….MB7FM off air
The Tring ‘parrot’ repeater has been quite handy for testing the MyDel-5189 70MHz rig that I’m currently reviewing. Tried to call it up on Tuesday evening without any success, so I wondered if the aerial had fallen off, but I was still able to work some local stations at the usual signal strength.
I checked with Selim, 2E0CKF in London to see if he was hearing MB7FM and he wasn’t either. So looks like there’s a problem.
Hopefully MB7FM will be back again before long – it’s a nice aid to 70MHz FM activity in the South-East. In the meantime, it’s always good to make simplex QSOs, in any case.
K0BAM reaches 1000 QSO milestone through FM satellites
I noticed a tweet from Jim, K0BAM in Colorado at the weekend, saying that he’d made over 1000 QSOs through the FM satellites. I asked him if he could send me some more information which I will use in the Practical Wireless column. Jim also shared with me this video, which I think you’ll enjoy too.
It’s something a bit different, but completely fascinating and using equipment that many of us already have – though that Arrow dual band antenna looks useful!
Congratulations, Jim!
