Ultralight DXing Report - Launceston Tasmania - 21/07/2015


Date: 21/07/2015
Time: 21:45 – 22:45
Location: Home, Launceston Tasmania
Radio: 7.5” Loopstick Tecsun PL-380
Total stations logged: 109
New stations logged: 0
Notes: Last night I had a fairly serious ultralight DXing session. Most stations I logged were as to be expected with no new stations logged. A number of New Zealand stations were logged at amazing signal level with 1386KHz (Radio Tarana) coming in almost like a local station. On 657KHz I heard what sounded like a religious program, these are the possible stations:
657        0_HPON                            Perth     WA
657        2BY                      Byrock  NSW (Confirmed)
657        8RN                     Darwin NT
657        Radio NZ AM Network                                Tauranga            I-NZ
657        Radio NZ AM Network                                Wellington         I-NZ
657        Star                      Tauranga            I-NZ
657        Star                      Wellington         I-NZ

I need to continue checking this frequency to help confirm which one it is. The signal was fading badly and mostly hard to understand.

783KHz also had traces of audio but not to a level where I could be comfortable with ID’ing the station.

1584KHz was also active with the “local” station 7SH fading in and out with possible “Coast Radio” from Napier-Hastings at very weak signal levels.

1602KHz had weak 3WL and weak but readable Radio Reading Service from Horowhenua New Zealand with a news story.

Planning a Portable Ultralight DXing Session

Updated - December 2015 
http://ultralightdxing.blogspot.com.au

For some people this would seem as easy as grabbing a radio as you head out the door; I have found that more planning is required to get the most from my portable Ultralight DXing session.

When I am planning a portable Ultralight DXing session my first step is to arrange a suitable day and time. I am happily married and we have small child so ensuring the domestic front is happy goes a long way to ensuring I can have a good time. Having all my domestic duties done and ensuring you have been spending enough quality time with my better half and child makes this easier. I like to try and arrange my outings around times when my wife won't be home or is busy; this makes it easier to be away from home. Only you known your own domestic situation and can assess the best way to do this, too often I hear of domestic situations where one persons hobbies or interests have a negative effect on the household as a whole. Normally I aim to have at least one portable Ultralight DXing session a week, normally a Saturday afternoon or one night during the week, however this can change based on the above. Of late I have been taking my daughter for more walks and quite often I take my ultralight dxing kit in the bottom of the pram in case I find a suitable location.

Once a suitable day and time has been found the next step is to check the weather forecast for that day. In the past when I was involved in the radio scanning / amateur radio hobby I used to undertake quite a bit of out and about scanning / sitting on hill tops / lookouts / mountains, from doing this I learnt two VERY important lessons: 
- Sitting in the sun for hours at a time is not fun and this reduces your enjoyment.
- Sitting in the cold for hours at a time is not fun and this reduces your enjoyment.

Based on this I like to make sure the weather will be suitable. While the cold can be overcome with extra clothes, being too hot is much harder to control and in extreme cases this can be quite bad for your health (dehydration, sun stroke and so on). Storms and other weather extremes are also not fun to be out in so I like to try and avoid these if possible. During our Australian summer’s bush fires are a very real risk and given most locations are prime fire spots, the fire danger rating (FDR) and a safe access / escape are very important to consider. The local sunrise / sunset are also checked and this helps with planning a suitable time to leave home to be at the chosen location to maximise any advantage from these different times of the day.

Next is to decide on a location, I like to have a mix of new locations and some proven ones. Some are quite close and others are quite a distance to drive. The things I consider when deciding on a location are: 
- Distance to drive (The cost of fuel is a factor in this, as is the amount of time I have) 
- Access (some areas are locked after hours) 
- RF profile (Some locations are better due to distance from AM stations) 
- Comforts (Shops, toilets, etc) 
- Personal Security / Safety (See notes below) 

Of these points, all are fairly easy to assess except for personal security, yet this is the most important. The city I live in is fairly safe and crime it is not always the first thing I think of, yet our personal security and safety is very important. Sitting in your car or walking in the bush with multiple radios, by yourself, after dark, in locations such as lookouts or hill tops, beaches, parks or car parks can expose you to an increased risk to your personal safety. These locations at times can be used by people for a number of reasons which may not be legal or which may cause you to witness things you didn't want to witness. Some of these locations are used for drug dealing, exchanges or people meeting others whom they are not married to in a "lover’s lane" type situation. Generally locations with a good level of passing traffic or close to houses are better than isolated spots.  Good lighting is also a benefit as is having multiple entry and exits points. The best advice is to keep your doors locked if in your car and to be aware of your surroundings both in your car and while on foot. If you feel unsafe or uneasy it is better to cut your session short than get caught up in somebody else's problems or risk your personal safety. Having a torch and a mobile phone plus telling somebody where you will be and when you will be home are all good safety tips. Some larger torches can be used as a weapon is the most serious of situations.

My planning really starts the night before or early in the morning when I prepare everything I am going to take, charge batteries and pack up my gear. My normal kit consists of this: 
- Receivers (1, 2, 3 or more in my bag)
- Batteries (Fully recharged and also some spare alkaline AA's)
- Head phones (I prefer the ear bud type and these are easier to carry)
- Log book and pen + spares
- Wire with clip attached for some shortwave listening if I feel like it.
- Torch
- List of all Australian and NZ AM stations by frequency order.
- Multi-tool
- Blanket (if it is cold) 
- Spare jacket / vest
- Digital camera
- Food and drinks
- Bandaids and a small towel
- Mobile phone
- Identification such as a driver’s licence (which you should be carrying anyway if you are driving)

In the past I have used digital camera bags and hard ABS type cases, these types of cases / bags each have advantages and disadvantages. ABS cases standout and make it look like you are carrying expensive equipment, which might not be a great idea in some remote locations. Soft cases on the other hand don’t provide enough protection in some circumstances, this I have found to be an issue with my 7.5” loop stick Tecsun PL-380. Recently I have taken the best of both worlds and made my own personal setup based on a digital camera bag with a strong inner hard case: http://ultralightdxing.blogspot.com.au/2015/07/stealth-ultralight-dxing-bag-mk2.html

Before leaving home I check my kit and confirm I have everything I need. When I arrive onsite I do a quick recon of the area to make sure it is safe, no dodgy people around and I feel comfortable. Then I do a quick scan of the bands and check for the normal stations, now I can sit back, relax and get serious about logging. If it is going to be an extended session in the car I get out of the car every half hour and walk around just to keep the blood moving and to get some fresh air. I also try to eat something and drink to keep my fluids up. I like to also get some photos each time I go out DXing for the report on my blog. If I am going portable I like to try a few different spots and also interact with anybody I see, even if this is just a passing hello on a track. On returning home I make sure I spend some time with my wife and daughter before checking my loggings and entering these in to loggings spreadsheet.

New Project - Hunting Down New Zealand Stations

As I have recently completed my "long term ultralight dxing project" and my new temponary QTH seems to produce amazing results with listening to New Zealand stations I have now started a new project to hunt down some New Zealand stations. 

I am still only in the very early stages of this, I am currently reviewing my previous logs and au/nz frequency list to find the most likely frequencies to target first, I will continue to share my loggings and results as this project continues.

Stealth Ultralight DXing Bag - MK2

Last month I decided to try and find a better way of carrying my ultralight radios, accessories and other bits and pieces I like to carry while out and about DXing, I looked around and weighed up using a bag against a hard carry case, I have used both methods in the past and each have advantages and disadvantages. I was keen to find a digital camera bag which was suitable but they were all either too big or too small.

Yesterday I happened to be out on another matter and noticed that a local retailer had a new line of digital camera bags, these were of various sizes and one was perfect for my needs, just fitting my 7.5” loop stick equipped TecsunPL-380 with some room to spare. This is the bag I purchased: http://www.ctponlinestore.com.au/sirix-digital-sib420-dslr-twin-lens-case

My plan was to attempt an improved version of my “stealth ultralight DXing bag” from early 2014, this time in a more suitable bag and with the advantage of what I learnt from this and access to a much better workshop to aid in the modification process. I wanted the keep the “stealth” look of a normal camera bag with the added protection of a hard case inside to protect my 7.5” loop stick equipped TecsunPL-380.

Some photos of the finished product are below, the hard case for my 7.5” loop stick equipped TecsunPL-380 allows for this to be removed from the top while still providing a good level of protection, this whole case can be removed easily as some double sided tape and the pressure of the other radio and battery charger are all that hold it in place (unlike my original case which was attached to the bag). The bag has enough spare space for one or two more ultralight radios when I move the battery charger to one of the other spare storage pockets. I can clip my camera to one side, drink bottle to the other, add a food bar and off I can go DXing, not looking like anything more than a photographer. The last photo shows just how much stuff I have been able to fit in this bag.

June 2015 Rockwork 4 Ocean Cliff DXpedition-- Ultralight Radio Results By Gary DeBock

(From the [ultralightdx] Yahoo Group)

For those interested in the latest discoveries in FSL antennas, modified Ultralight radios and ocean cliff transoceanic propagation boosts, an 11-page report covering the Ultralight radio portion of the recent Rockwork 4 Oregon cliff DXpedition has been uploaded to https://app.box.com/s/co2jwyzt8mdtdeqlud2tsp85jajd7x1a 
 
Although my Perseus-SDR DXpedition partners Chuck and Tom are still reviewing their files for this trip, the linked DXpedition report includes a detailed propagation assessment for each of the five days from June 25-29, multiple site photos, MP3 recording links for each of the 31 South Pacific MW stations received on Ultralight radios (22 New Zealand, 7 Australian, 1 Tahiti and 1 Fiji) plus a narrative on the challenges and rewards of chasing transoceanic DX from the edge of a 400' (122m) plunging ocean cliff. This awesome cliff was the site of the best New Zealand MW-DXing results ever obtained in North America, recorded by my DXpedtion partner Chuck Hutton last July. 
 
73 and Good DX,
Gary DeBock (in Puyallup, WA, USA)
