Colin Butler, M6BOY, is the host of the ICQ Podcast, a weekly radio show about Amateur Radio. Contact him at [email protected].

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!

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.

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.

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?

The antenna

Overall I have been very pleased with the purchase of the MFJ 1788 loop antenna. Considering the location I am in and the restrictions of a condo such as.....concrete all around you, other buildings blocking your signal, very small space to put an antenna and power level must be kept low as to not affect the neighbors. After doing considerable searching for the right antenna for this location it boiled down to this antenna. The power I run is 5 watts max and this is not new for me as I have been a QRP op for years now. Below are the reasons why I am pleased with this antenna to be followed by some of the not pleasing things about the antenna.
1. Very small foot print for an antenna that will give you 15m to 40m.
2. The antenna can be used mounted horizontally or vertically.
3. Once you get used to the tuning it's very fast and easy to tune.
4. I covered my antenna with as to keep it low profile and it works no problem with the cover.
5. The antenna remote control can operate either on AC or batteries.
6. Can be mounted on a simple tri-pod.

Some of the draw backs
1. The quality of the antenna is low, I had to make some adjustments to make it work as it should.
2. The band width is narrow and retuning has to be down often.
3. The SWR meter in the remote control unit is not very reliable.
4. Buzzer used to tell you the coarse tuning has finished is VERY hard to hear.

Repairing Cap spacing

On air results with this antenna have been good, with regards to receiving I have been able to hear the Middle East, South Pacific, Europe, South America and of coarse North America. Now hearing a station and contacting the station is another ball of wax. With my power restrictions I have made some very satisfying contacts. My modest signal has made it into South America, all parts of Europe, Iceland and Africa so far. There are two Loop antennas that MFJ makes and if I was to make the choice again I would had gone with the MFJ 1786 as it covers 10m to 30m. I have found with this antenna there is no way to tune it below 15m. The characteristic of the tuning capacitor will not allow it. I have read the MFJ 1788 is like a wet noodle on 40m and it's true I have not been able to make it into the U.S. The MFJ 1786 would had been a better choice with more band opportunities.

At 1936z G8VDQ (93km) in IO91um was spotted here at -26dB S/N.  When there are GDX stations they seem to be copied. G8VDQ’s signal had -3Hz Doppler, suggesting aircraft reflection was involved.

UPDATE 1950z:  Es is still in evidence with DK6UG spotting me 4 times (so far) now at around -22/-23dB S/N.

UPDATE 2120z:  Es again; this time  IK1WVQ (1084km)  spotted at -20dB S/N.
