Tuning 50 and 70MHz over a coffee – and an interesting blog (SV5DKL)

Tuning around this morning, 50MHz hasn’t been massively open, but there have been some interesting signals popping up. First thing as I was drinking my first coffee, I worked IK6HIR from JN63 who came up quite nicely for a while. I6WJB was heard calling CQ DX, so I didn’t call him, but he was a decent signal.

Although I don’t use clusters much these days – especially on HF, this Es season I have been looking at dxheat.com which is a very nice web based cluster and allows me to filter everything except 50 and 70MHz spots. I noticed a 70MHz spot fly by of Martin GM6VXB on 70MHz meteor scatter. I tuned to the frequency in question and did get a short burst from him, but not enough for a QSO. Hardly surprising, given my vertical antenna.

Returning to 50MHz just before getting some chores done, I tuned around the CW end and SV5DKL (KM46) was coming through. With the small antenna, I don’t work SV, SV5 or SV9 very often from here, so dropped in a few calls. Signals were quite weak and then, in typical Es fashion peaked up to S7 or so and I was able to sneak a QSO in, which was very nice. The distance is just under 2900km, which I think is ok for the setup here (SV5DKL was doing all the work, of course)

As I frequently do, when I work someone, I tapped his callsign into Google and found that Efstathios has a very nice blog, with information about his operating and QSOs, particularly on 50MHz.

Tony, KD8RTT launches YouTube channel

My friend Tony, KD8RTT, is an Extra from Cleveland, Ohio. He has launched a new YouTube channel and is giving away prizes to four lucky hams who subscribe in order to get new followers.

Tony is a sophomore studying engineering at Rose-Hulman Institute of Technology in Terre Haute, Indiana.

It’s always great to see a young ham jump so enthusiastically into the hobby. From his recent trip out to Hamvention to operating maritime mobile from a Disney Cruise, Tony has done a fine job documenting his ham adventures on video.

Great job with your videos, Tony. Keep up the hard work!

Concentrate on 6m and 10m?

10m is my favorite band of all: there is the possibility of local QSOs on 10FM out to 30-40km (at least) even with very modest (CB level) powers to a 1/2 wave vertical. It is good for GDX with suitably equipped stations out to many hundreds of kilometres. F2 and Es propagation allow really long distances.

6m is the “magic band”. It seems to be good for locals and GDX seems to work out pretty well too out to several hundred kilometres, as for 10m. Although F2 is rare except close to good sunspot maxima, Es is there every spring and summer and at other times too, but more rarely. More stations active (e.g. on WSPR – a great DX mode) would indicate more openings, I suspect.

Actually one could do a lot worse than concentrate on WSPR on these 2 bands only. That is what I may do in future. In effect I  am already doing this, but I could better optimise the antennas – maybe a 1/2 wave vertical on 10m and a halo on 6m? My antennas may be compromised but in my present state of health (stroke) they will have to do.

UPDATE 1820z:   All afternoon on 6m it has been just locals G4IKZ, G4KPX and G0LRD only here with no signs of GDX or Es at this QTH. Things on the “magic band” can change quite quickly, so I shall be staying on 6m for the rest of the day. We’ll see.

UPDATE 1830z:  Looking back through the WSPR logs I see G3IGU (172km) near Doncaster was being spotted here at 1254z with only very slight Doppler or warm-up drift (-1Hz).  This may have been tropo or a favorable aircraft again. So there was some GDX around.  I have seen a surprising number of GDX stations now on 6m at decent distances. Theseare all “accidental” spots – no skeds, I just happened to see these stations.

As I write this I see G6AVK (78km) is spotting my 1W ERP at -27dB S/N at 1830z , yet more GDX.

UPDATE 2030z:   Just the locals reporting me. No Es or GDX currently.

UPDATE 2155z:   Still just the locals.  Soon be time to pull the big switch to off.

Back to 6m

After a fun day on 10m, I’ve now gone back to 6m and my 1W ERP was immediately spotted on WSPR by locals G0LRD and G4IKZ. On the lookout for more distant 6m stations now by any mode.

UPDATE 1120: G4KPX (14km) is spotting me well on 6m and the first 6m GDX today G4HBA (189km) using 10W from IO93fn square (near Barnsley, Yorkshire) is being spotted here at -25dB S/N with 3Hz Doppler, suggesting aircraft involvement.

10m Es and early morning MS?

LB9YE and I have been exchanging WSPR spots since 0458z this morning. In both directions there is considerable Doppler. On another signal (not currently decoding) there are clear signs of meteor reflections as the signals are strong but in short bursts. I wonder if MS was playing a part in LB9YE’s decodes?

Earier in the night PB0AIC (288km) was decoded STRONGLY at -8dB S/N . At this range I assumes this was early morning tropo or again possibly MS? At the very same time 0404z, G8VDQ (93km) , was decoded strongly at -12dB S/N.

Otherwise all quiet on the Es front.

I do wonder sometimes about Es (SPORADIC E-layer) reflections. Many signals do come into this category with fleeting, often quite localised, strong openings, but many others are anything but sporadic. Are these really Es as we know it or some other propagation?
