I have owned this rig for several months now but it hardly get used as I prefer, because of my poor voice, to run my WSPR beacon on 10m.  It certainly works well with my last QSO being a W8 on SSB.

In the picture, the small WSPR beacon is far left with the Lincoln  with green illumination on the left of the FT817s and to the right of the WSPR beacon.

Short form reviewing the MDT kit from Ozqrp a few weeks ago, and then watching the VK3YE Video, gave me the urge to purchase a MDT40 kit. Of course miles are no barrier to this hobby any longer, a quick click and it was in the shopping basket. I coughed up the green ones or Pound notes and sent it over via Paypal.

Less than 10 days later a card dropped through my letterbox. Please pay up? "Unfortunately we can't deliver your item because there is a fee to pay". Meaning it was  subject to UK Import Duty of £7.63, plus a £8 Post office charge on top! I really don't mind the Tax, but the Post Office charge of £8, I find this a big no no! A fee for them to handle it and take my money. The Post Office deliver parcels and letters everyday from around the world, and never ask for anymore, until we get into stuff with duty added by customs and then they add this extra sting on top of the bill.

This made the total of the purchase including duty a little over £61. The tax might have taken the icing off the cake, but the kit still represents excellent value for money.  Please don't be put off, Ozqrp has done an excellent job of design, and putting this kit together as you will see below:





Post office then satisfied, I walked away with a receipt and the MDT goody box..



The components came well packaged in a sealed box, with all components wrapped in bubble wrap inside. 
 
VK2DOB the owner of Ozqrp has done an excellent job collating all the components together for the MDT, all which have been separated off into little bags and clearly marked. The case comes with pre drilled, clear labelled, front and rear separate panels for the unit, including the hardware and the knobs. Even a Microphone plug has been included in the kit, so you won't have to spend time hunting around or having to go out to purchase one.




A well designed doubled sided PCB, which already has the only SMD component (the varicap diode) soldered to the board . This will save everyone time from fiddling around, especially those like myself with ailing eyesight.






Last night I printed out the manual and bound it up into a simple folder. I recommend everyone print out "all" the 42 pages, and read it from cover to cover a couple of times before starting. Although what may be quite a simple and straight forward process to me, there is still quite a bit for the novice to take in.



The next time I write on this blog I guess certain parts of the kit will be completed? For now, I leave you with two more excellent VK3YE MDT videos, including extra modifications of the unit.

Well, thankfully, this is not happening during this contest weekend: one of the largest sunspot regions during this Sunspot Cycle 24, and one of the biggest in several decades, gave us quite a show, back in October 2014.

Five major X-class (very strong) and a number of moderate and “mild” solar x-ray flares erupted from a single sunspot region – this video covers the time period of October 19-27, 2014, as captured by NASA’s SDO spacecraft. This is from what has been one of the biggest sunspot regions in a number of decades.

Between October 19 and October 27, 2014, a particularly large active region on the Sun dispatched many intense x-ray flares. This region, labeled by NOAA as Active Region (AR) number 12192 (or, simply, NOAA AR 12192, and shortened as AR 2192), is the largest in 24 years (at that point in Solar Cycle 24).

The various video segments track this sunspot region during this period (Oct. 19 – Oct.27, 2014), during which we can see the intense explosions. There are five X-class flares during this time, and NASA’s Solar Dynamics Observatory (SDO), which watches the sun constantly, captured these images of the event.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

When referring to these intense solar eruptions, the letter part of the classification, ‘X’, means, ‘X-class’. This denotes the most intense flares, while the number, after the classification letter, provides more information about its strength. For example, an X2 is twice as intense as an X1, an X3 is three times as intense, and so forth.

Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peak to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around world. Join in on the fun on the first full weekend in August and see how many of the mountaintop stations you can contact. The prime operating hours are on Sunday August 2nd from 9 AM to noon local time (1500 to 1800 UTC), but activity can occur throughout the weekend.

Now including Summits On the Air (SOTA), which adds over 1700 potential summits! If you aren’t up to climbing a 14er, there are many other summits to choose from (with a wide variety of difficulty). See the W0C SOTA web page at w0c-sota.org

Radio operators who plan to activate a summit should set an “Alert” on the SOTAwatch.org web site. To subscribe to the “ham14er” email list, visit the yahoo groups site at http://groups.yahoo.com/group/ham14er/. Also, be sure to check out the event information at http://www.ham14er.org

Frequencies used during the event
Activity can occur on any amateur band including HF and VHF. The 2m fm band plan uses a “primary frequency and move up” approach. The 2m fm primary frequency is 147.42 MHz.  At the beginning of the event, operators should try calling on 147.42 MHz. As activity increases on that frequency, move on up the band using the 30 kHz steps. Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.45 MHz, followed by 147.48, 147.51, 147.54 MHz.

Frequency (MHz)
 147.42 Primary 2m FM Frequency, then up in 30 kHz steps
 223.5 Primary 222 MHz FM frequency
 446.000 Primary 70 cm FM frequency
 446.025 Alternate 70 cm FM frequency
 52.525 Primary 6m FM frequency
 144.200 2m SSB calling frequency
 50.125 6m SSB calling frequency
 14.060 20m CW Frequency
 14.345 20m SSB Frequency
 18.092 17m CW Frequency
 18.158 17m SSB Frequency
 21.060 15m CW Frequency
 21.330 15m SSB Frequency
 28.060 10m CW Frequency
 28.350 10m SSB Frequency
 Other Bands/Modes:
 Standard calling frequencies and/or band plans apply.

Warning: Climbing mountains is inherently a dangerous activity. Do not attempt this without proper training, equipment and preparation.

There is no doubt about it.

This summer's Sporadic-E season has been the worst in memory, for myself and for most North American six-meter fans. My last log entry, and the last time that I heard a signal on 6m, was on July 7th. During a 'normal' season, rarely a day goes by without an opening in some direction. Often, the band will be open for several days in a row. It was only a few summers ago that the PNW region had propagation to Europe (extremely rare) for three days in succession!

There has been much speculation as to why this season is particularly poor. Is it the early higher-than-normal temperatures being experienced this summer? Is it the constant bombardment from the sun, with several solar flares during the prime weeks as well as an almost continuous coronal hole streaming? Is it all just a normal part of the cyclical behavior of most natural phenomena? Whatever the reason, time is running out for this year.

After operating on 6m for over 40 years, the peak conditions always seem to happen during or close to the first week of July ... but, living up to its 'sporadic' classification, I have seen some spectacular openings right up until early August. In fact, my longest 2m Es contact (Oklahoma) was made on July 24, so there is still some time left for the band to exonerate itself.

With the sun flatlining once again, and no sign of flaring or no coronal hole streaming, perhaps the next few days will turn things around. If not, the summer of 2015 will be notable for not being notable.

One great opening over the pole will make the poor conditions just a distant memory!
