Lightning damage risk

I am always nervous about lightning strikes.

The excellent Southgate News today told the (true) story of a local CBer who had his vertical and CB rig destroyed by lightning. See http://www.huntspost.co.uk/news/latest-news/

I usually disconnect antennas when there is lightning about but I am still nervous.  One of my friends (not a radio ham and with no big antennas in the air) who lived in a normal estate home had his home struck years ago and it took out lots of his household wiring. The chances of a direct hit are rare, but I am always bothered and never quite sure what the best advice is.

6m GDX tonight

No Es here on 6m WSPR since I QSYed to 6m around 1500z. There has been some GDX again, G8JNJ/A (184km) was spotting me at -24dB S/N at 2128z.  Doppler was low suggesting tropo without aircraft reflections, or aircraft crossing the path at right angles (so little/no Doppler).

Again I am bitterly disappointed with the lack if USA/Canadian east coast stations on WSPR.  As of 2145z there were still ZERO stations active on WSPR from that area. Come on lads! Give we Europeans a chance of being spotted over there!

Unless there is some interest from the east coast USA/Canada on WSPR very soon it will be time to abandon 6m WSPR this season. I have been spotted all over Europe, in N.Africa and in Israel (3519km) with just 1W ERP in the last few months.  I was hoping for the USA or Canada on WSPR this season. If there are zero stations at the other side there is no point in continuing.

New Chinese multi-mode HF rig – Xiegu X108

Steve, G1KQH has sent this link about a new Chinese multi-mode transceiver.  See http://www.brickolore.com/ . Prices start at 2800 Yuan apparently. It is called the Xiegu X108. There is a video and some pictures of the rig.

To my mind, this still looks like  a “back shed” radio, rather than a mature, well engineered and  thoroughly well tested radio. I may be wrong. I am still waiting to see when the Chinese launch a proper Yaesu or Icom competitor. These will come but I’ve not seen one yet. Maybe in the next 12 months?

Great amateur radio-related technical explanation videos

While searching for an informational video about exactly how parasitic antenna elements work, I found a treasure trove of ham and electronics videos made by Stan Gibilisco, W1GV. There’s a lot of good information here and his YouTube channel is worth a bookmark.

Ten-Tec Argonaut VI

See http://www.tentec.com/argonaut-vi-qrp-1-10-watt-transceiver/

Despite missing some key bands, all reports are this is a very good QRP radio from Ten-Tec. However at $995 in the USA (similar in £ in the UK with import duty and VAT tax) it is simply too expensive to ever consider.

All I can say is are Ten-Tec in financial trouble? The true market price  here in the UK must be less than £700, so they are about £300 adrift in my estimation.

Even in the USA $995 for a rig with no 60m, no 12m and no 6m is way over the top. Just compare with the FT817ND for example. Even the Elecraft KX3 is much better value,  in my view.

Views?

Does it get any better?

I suppose it can.  I suppose one could make DXCC Honor Roll, or perhaps get elected to the QRP Hall of Fame, or perhaps invent some cool, new piece of QRP equipment that the world will beat a path to your door for (and make you some $$$ in the process!).

But for a Ham an’ Egger like me, the best is just getting on the air making contacts – ANY kind of contacts.  DX quickies, ragchews – whatever.  It’s all good. And today was another comparatively good lunchtime QRP session.  I worked RZ1OA, Vlad in Russia, and I worked XE1XR, David in Mexico. Two good, solid DX contacts.

The best QSO was the last one, and it was not a DX contact. In fact, the miles covered were only about 650. But it was exciting, fun and satisfying nonetheless.

After working the two DX stations, I decided to go to on down to 20 Meters to listen perhaps for some SOTA stations.  That’s when I heard a weak, but very copyable KC8JNL calling CQ right at the QRP Watering Hole.  I answered and hooked up with Pat who lives in Rothbury, MI.  Not as distant as Russia or Mexico – definitely.  But this QSO was exciting in and of itself, because Pat was using a Rockmite at QRPp power levels.  There was some vicious QSB, and I didn’t quite copy Pat’s power output level. Having my own 20 Meter Rockmite, I knew it had to be under 1 Watt.  Pat gave me a 559 and I gave him a 459 in turn.  The QSO would have been Q5 copy both ways if it weren’t for the QSB.  But even with the fading, I knew what Pat was saying to me, and from his answers, I had a good idea that he was making me out just as well.

QRP to QRP, or QRP to QRPp, or even QRPp to QRPp QSOs get my wonderment juices all fired up.  That we can effectively hold a conversation using such little power is still an amazement to me after 36 years in this hobby.  It’s truly like …. can it get ANY better than this?  (My apologies for speaking like a teen – having two, it tends to rub off). I talked with Pat and Vlad and David today, all while enjoying the sunshine and the 80F (27C) temperatures that we are having here today. No wires, no cell towers, no infrastructure of any real sort ….. not much more than two guys shooting a bunch of electrons out of some wire or aluminum – hoping that they’ll bounce around to and fro, and eventually be picked up by a like minded enthusiast – somewhere.

Magic. Pure magic.

QRP – When you care to send the very least!

It was the coax!

After being stuck inside during lunchtime last week, due to workload and/or weather, I was finally able to get out today.  This was the first opportunity (if you don’t count the weekend) that I had to try out the tri-magmount with the Buddistick since changing out the coax. Well, it was the coax that was giving me fits.  With the new coax, the KX3 tuned the antenna in mere seconds and once it tuned, it stayed tuned. No phantom jumping SWR values, everything behaved nicely.

For my efforts, I was able to work W1AW/5 in Arkansas on a different band, Don K2DSV who is a fellow K2ETS Club member, as well as XE2ST, Fernando in Nogales, Mexico.  So I am considering the surgery that I performed on the antenna base to be an unqualified success.

I also spent a lot of time thinking about a posting on KB6NU’s blog about how “New Hams are Different” and the responses that Dan has received.  I think that times have greatly changed, or maybe that’s just my perception.  When I was a Novice back in the late 70s, and joined a local club (which is no longer in existence – and this may be the reason why) there was a kind of a “keep your mouth shut if you’re a Newbie” mentality going on.  New callsigns appearing at meetings or on the repeaters weren’t welcomed all that enthusiastically (as a result, that may be why I’m not real big into VHF/UHF to this very day).  I guess there was kind of a “pay your dues” mentality, back then.  For better or worse, that was the way it was. But guess what? I survived, more or less.  😉

I really believe that I saw that change in the mid 90s, though.  I joined a couple new clubs and was welcomed.  Even though I was licensed for quite a while by then, I was still a neophyte compared to the established “Old Timers” who were a large part of the membership, and I was a comparative stranger, to boot. But in both cases, I was welcomed warmly – I was not shunned, I was not looked down upon, I was accepted into the groups without question.

And that’s the way it should be.  I currently belong to three active local clubs – the K2ETS Electronic Testing Society of NJ, the W2QW Raritan Valley Radio Club as well as the NJ2SP South Plainfield Amateur Radio Club (which I helped to establish).  Since SPARC is so new, I am going to leave it out of the mix for this discussion, but the same philosophy holds there, as well.  In both K2ETS and W2QW, newcomers are welcomed enthusiastically and with open arms.  There’s no “we vs. they” mentality when it comes to new members. Everyone is encouraged to participate, and everyone is listened to. Your age, your gender, your level of experience is really of no matter.

I really don’t see any wide gulfs when it comes to “new” vs. “old” technologies, either.  Those who primarily operate HF only seem to peacefully co-exist with those who like to experiment and build and toy around with Arduinos, Raspeberry Pi’s and the digital voice and data modes.  In fact, I see a lot of the groups co-mingling and getting pointers, answers to questions and operating tips from each other.  Just the way it should be.

Newcomers are welcomed for their new ideas and enthusiasm while “Old Timers” are respected for their experience and built up wealth of tribal knowledge – again, just as it should be.  Guess I’ve been very fortunate to not be involved with “cliquey” organizations. Hopefully, that is becoming everyone else’s experience as well.
