Another Activation this weekend.....

Sent to me by Tom, KC2SFU:

A group from the Adirondack Fire Tower Radio group in Chenango County, NY, will be activating the fire tower at Stamford, NY, this Saturday.

The goal of this group is to promote the idea of operating from current and former Adirondack Fire Tower locations.

The group will be on air starting around 0800L (EDT) and will be on 2M (SSB 144.205), and (FM 146.520). they will also be on HF 40M (7.186 ssb), and may even work a satellite or two.

The group hopes to hear you on the air.  For those of you with an interest in joining in, here's a great page (HERE) that lists most of the fire towers in the Adirondacks.

Another Island Activation

I received an email from John VE3ISE this afternoon.  John lives in Grimsby, Ontario, and is planning an island activation in the near future. 

His email is below:

Myself and a couple of friends will be activating Byng Island ON-037 on Saturday September 8, 2012

We hope to arrive before Noon on Saturday, set up and be on the air by , no later than 12 noon. All depending on local weather conditions.  All QSL's should go to the operators home call.

Two stations will be running: 

John VE3ISE on 40 Meters 7150 ( +/- 10 kc) from 12 to 2 Pm then switching to 20 Meters 14260 ( +/- 10 kc) running 100 watts to Hustler verticals.

Doug VE3GJ on 20 Meters, HF Back Pack Frequencies running QRP.


This activation has also been listed on the US Islands Award website, and a copy of the email has also been sent to the Canadian Islands Award website.

Point Petre Lighthouse

Glenora Ferry
For a Sunday 0530L came pretty early!!  Luckily I had loaded the truck the night before so the noise was kept to a minimum,  "SWMBO" could sleep in peace, and I wouldn't be in trouble for waking her up at that unGodly hour! 

Once again the weather was just glorious, bright blue sky, with just a few clouds blowing by, and the Timmy's coffee nice and hot. 

Then it was off down Hwy 33 East to Glenora, meet up with Don-VE3MNE on the road, hop on the small ferry over to Picton and a stop for a good breakfast at the very appropriately named Lighthouse Restaurant.

The drive from the restaurant to the lighthouse takes about 30 minutes over some pretty remote country roads through farming country.  Point Petre is at the very tip of the South-West corner of Prince Edward County.  The whole area is a wildlife and bird refuge, and it streches for many miles along the shore of Lake Ontario.  This area has been left as remote as it has because it was, in an earlier life, an anti-aircraft artillery range for the Royal Canadian School of Artillery (Anti-Aircraft) based nearby at Camp Picton.

Camp Picton in 2012
The school provided training for anti-aircraft gunners, gunnery radar operators, technical assistants and artillery instructors. A number of operational artillery units were also located in Picton, including the 127th and 128th Medium AA Batteries, Royal Canadian Artillery (RCA) and the 2nd and 3rd Light AA Batteries of the 1st Light Anti-Aircraft Regiment, RCA. The RCAF also maintained a small detachment at the base to provide aircraft targets for the gunners. 

Camp Picton closed in 1969 as it was surplus to DND's requirements.  Today it is used by small private aircraft and the Royal Canadian Air Cadets.

We started to setup as soon as we arrived at the lighthouse, which still looks as pitiful as it did last year, with its supporting building looking shabby and all boarded up.

Don and I both brought our FT-857D's.  I put up a 6m dipole and a 2m four element yagi, and Don put up his "chilicon vertical Mk.2" with 12 radials of various lengths and operated up on the HF bands.

The bands were not in very good shape today as we quickly found out.  All bands seemed to have some very deep QSB, and the conditions were really bad. We managed a grand total of eight contacts in five hours...pretty miserable really.  We had no response to our CQ's on 2m SSB and 6m SSB at all, just empty air.

Our HF contacts included five US lighthouses.  Our small log is as follows:

W4J at Lighthouse US-0025 on 20m
WS1SM at Lighthouse US-141 on 20m
N1NC at Lighthouse US-116 on 20m
N8MR at Lighthouse US-253 on 20m
N2CMC at Lighthouse US-011 on 40m
W9IMS in Indianapolis on 17m
EA8AM in the Canary Islands on 15m
KA4WJR in Ocala, Florida on 20m

The SFI today is 97;  the A index is 11; the K index is 2; and the SN is 56.  Of the three years we have activated this light for the ILLW, this has to be our worse showing ever.  Hopefully next year we can redeem ourselves.

Thanks to Tim who posted us and our frequencies on the DX Cluster.

Nine Mile Lighthouse

Dave VE3DZE antenna
Today the Frontenac Radio Group activated the Nine Mile Lighthouse on Simcoe Island for the International Lighthouse and Lightship Weekend.  The lighthouse is number CA-0031, and the island is ON-022

Dave Ve3DZE and Tim VA3TIC both went over early this morning on the ferry to Wolfe Island and then onto the very small cable ferry to Simcoe Island.

They had superb weather, with beautiful blue sky and a cool breeze, and not a cloud to be seen. 

The bands however were not in the best of shape with the SFI sitting at 97, the A index at 11, the K index at 4, and the SN at 42.

The two of them hung in there and between them they made over 70 contacts on the two HF stations.  Interesting to note that all of the contacts were either Canadian or American, no DX at all.  I managed to work both of them on 20m and 40m at 0930L, and then went on to work a pile of other lighthouse who were also on the air.

Nine Mile Point Lighthouse from the road.
This is the first half of our weekend Lighthouse activations, tomorrow, Don VE3MNE and myself are leaving at 0600L to drive to the south western corner of Prince Edward County to activate Point Petre Lighthouse, CA-0026.  Hopefully we wil have the same weather, but better SFI numbers!

I'll post our report tomorrow evening.  Look for us tomorrow on 20m between 14,250 and 14.260, or on 40m at 7.250 +/- 10 Kc.

The 31' Homebrew Vertical


Several people have asked me to post the results of our field test of the homebrew 31' vertical antenna.  Here it is:

Background –


At Chilicon 2011 some of the members of the Ottawa QRP Society arrived with a homebrew vertical antenna. It had a 28’ radiator, one 16’ ground radial, one 31’ ground radial, and a 4:1 Balun, all designed by Martin-VA3SIE. It intrigued VE3CLQ with its simplicity, and its possibility as a ground-wave antenna for emcomm work.

VE3CLQ built one at Chilicon 2011 using a MFJ-1910 collapsible mast, a 28’ radiator, four 16’ ground radials, and a 4:1 Balun. This antenna was not analyzed before use, but with 40w output from a FT-857D it worked VK3MO in Victoria, Australia and VK2KRR in New South Wales, Australia from his campsite.

Further Development –

Richard-VA3VDP played with the design using the EZNEC antenna design computer program for a few weeks and came up with the result that a 31’ radiator would work best with the 16’ ground radials. A rebuild of VE3CLQ’s antenna ensued and it was soon sporting a 31’ radiator, this antenna is now known as the Chilicon Vertical Mk.2.

VA3VDP bought the commercial version of this antenna, made by LDG, and called the S9v31 and is advertised to be good for 6m through 40m.

Over the past 12 months the antenna has been used, both the commercial and the homebrew versions, with good success from a variety of locations and grounds. A great deal of DX has been worked to date with it.

The only change to the Chilicon Vertical Mk.2 has been with the number of and the length to the ground radial system. 

Testing –

In order to find out which Balun, either a 4:1 or a 1:1 was more efficient, a test was designed. The antenna was set up at Lamoine Point, in a gravel parking lot.

The antenna was set up with the 31’ radiator, six 16’ground radials, and a 4:1 Balun. Frequencies where chosen close to the centre of each band for operating SSB. With exactly the same set-up we switched to a 1:1 Balun and the same test run again. The results were:

The 4:1 Balun
Frequency        Result
3.800                6.5:1
7.150                3.5:1
14.150              2.5:1   
21.200              1.8:1   
28.500              2.1:1   
53.0                  1.1:1       


The 1:1 Balun
Frequency         Result
3.800                12.1:1
7.150                2.6:1
14.150              6.3:1
21.200              1.6:1
28.500              4.5:1
53.0                  1.3:1

The antenna was set up for a second test with the 31’ radiator, six 16’ground radials, a 4:1 Balun and the addition of two 31' ground radials. Frequencies where chosen close to the centre of each band for operating SSB. With exactly the same set-up we switched to a 1:1 Balun and the same test run again. The results were:

The 4:1 Balun
Frequency           Result
3.800                  6.1:1        
7.150                  3.1:1        
14.150                2.4:1        
21.200                2.1:1        
28.500                2.1:1        
53.0                    1.1:1        

The 1:1 Balun

Frequency          Result

3.800                 12.1:1
7.150                 2.8:1
14.150               6.3:1
21.200               2.4:1
28.500               1.3:1
53.0                   1.4:1

The results show that the addition of the two 31’ ground radials did very little to change the feedpoint impedance of the antenna.

We then checked the resonance of the antenna using both a 4:1 Balun and then the 1:1 Balun. The results are:

The 4:1 Balun
Frequency          Result

9.500 MHz        1.0:1
19.700 MHz      1.0:1
42.600 MHz      1.0:1
61.900 MHz      1.0:1
132.000 MHz    1.0:1

The 1:1 Balun
Frequency           Result

7.500 MHz         1.0:1
35.000 MHz       1.3:1
64.500 MHz       1.1:1

On Air Test -

The antenna was quickly reconfigured to the 31’ radiator, six 16’ground radials, two 31’ ground radials and a 4:1 Balun. The antenna was then connected to an IC-703 10w QRP transceiver and a 12v 35Ah gel cell battery.

The results of the on air test are:

1901UTC    20m   G8A           57/55    Brian, Great Sutton, UK
1907 UTC   20m   VY2TT      58/56    Ken, Bloomfield Stn, PEI
1921 UTC   15m   CM8AKD  57/56    Jose, Las Tunas, Cuba

The SFI for that time was:

SFI = 129;  A index = 5;  K index = 3; and SN = 91.


Conclusion –

In its present configuration as the Chilicon Vertical Mk.2 it works very well and is especially good when hunting DX.

Further testing is scheduled to be done with more radials of different lengths.  If there is suffient interest I'll post the results.
