No more Elecraft radio

Elecraft does not allow us to order their product directly because they only distribute via Japanese distributor.  I have owned Elecraft radios, K1, KX1, K2 and K3 and I payed a lot.

Elecraft announced they accept KX3 order and our distributor also announced. Look at following price list for KX3 Kit (with no option).

Elecraft says: $899.95  This will be about 80 Yen x 899.95 = 72,000 Yen
Our distributor says: 132,200 Yen

As I have TS-590 and K3 so for me KX3 is not base radio but DX vacation radio. KX3 need external AMP to get 100w.
As I have FT-857, K2 and Eagle which all run 100w so KX3 is not attractive at all.

If I want to replace these radios for DX vacation in near feature then I will look for a way to buy directly (not via our distributor)


Great news from Elecraft....."Elecraft now sell direct to JA"

3D2YA from OC-156 in 2012 Update

Expected Antenna for 20-10m Band will be Bravo-5 vertical Dipole by N6BT.
It is very small but effective antenna. I modified a little bit to be packed in standard suitcase. The longest pipe is now under 70cm.

This is Bravo-5 at test site near my house and a example of SWR. The Band width seems about 200KHz on 20m.

Radio for my DX Vacation

These are Radios I have used since 2008.
As whole weight is generally limited my target weight is under 50-60 pounds (23-27Kg).
Generally speaking FT857 will be the best if weight is very severe. Eagle is the best only if weight is not severe.

K2 is best radio for CW but very poor for Digital Mode. Audio level setting is very critical to keep stable output power.  Any idea will be appreciated.

I will take FT857 or Eagle somewhere in South Pacific next year.

JA1NLX/VK4 from OC-187 The END

Log has been uploaded on LoTW server.

1306 QSL cards have been printed/sent via Buro (by GlobalQSL)
267 QSL cards not yet.

This is QSOs/Band sorted by Continent chart. Not too many QSOs with EU and NA due to poor condx.

I will try again somewhere in South Pacific next year too. Hope to work you again.  Thanks !!!

JA1NLX/VK4 from OC-187 Story

This is a story of JA1NLX/VK4 OC-187

Arrived at Lizard Island Resort at 1200 Local time (GMT+10H) after 21H trip.

My room is located at at 30m high above beach. There are a lots of bush and trees between my room and beach. I decided to set up antenna at balcony. Vertical element is about 6m long wire wounded on fishing pole. 2.5m x 80 radials are raid on balcony flore. I have good match with Z11 Pro ATU. This is my Antenna and Transceiver etc with local beer.

QRV started at about 1400. As I was tired with long trip I worked only 100 QSOs today. Everything tomorrow.

It is Winter season here in Australia. Weather is very good with sun shine and low humidity everyday.

In the morning Band opened for NA and JA on 21MHz. In the afternoon 24MHz was good for JA and EU.
In the early evening I enjoyd many QSOs with JA and EU on 18MHz.

In the morining Band opend for JA and NA on 21MHz. In the afternoon I enjoyed QSOs with JAs on 28/24MHz and some EUs on 24MHz. In the early evening I worked JAs and some EUs/NAs on 14MHz. 2230 was best for East coast of NA.

Condx was very poor in the morning. I worked almost nothing. In the afternoon I worked some NAs and EUs on 14/18MHz. In the early evening I tried 10MHz and worked almost JAs. After that QSYed to 14MHz and worked some EUs.

I will QRT in the early evennig today and pack all my stuffs in bugs for tomorrow morning departure.
I added some more QSOs with NA on 18MHz and EU on 14MHz. Condx was not good for these area though.
Total QSOs 1500, including 200 with EUs and 100 with NAs. I tried SSB and RTTY a few times with no luck.

This is dinner with friend, Bill and his wife.

This is very friendly resort for HAM. I enjoyed very much thanks to thier great support.
As I said before there were a lots of bush and trees, They cut down a few trees for me to see great sunset from balcony this morning. Great serivece !!!

Generally speaking Eagle Transveiver and Random wire antenna worked very well. I had no RFI problem evenif ATU matching was stable.
I know quite well that my sigs is not strong. I apprecite your patience. For me it was not easy to pick up your sigs too. The sigs from EU and NA were weak with QSB. I did my best to pick up you.

JA1NLX/VK4 from OC-187 updated

Propagation forecast in August by VOACAP online says that the window may open ........

For EU
05z - 07z on 14MHz, 08z - 10z on 21MHz, 10z - 12z on 18MHz, 14z - 16z on 14MHz and 21z - 23z on 14MHz

For NA
00z - 06z on 21MHz, 04z - 08z on 18MHz and 06z - 13z on 14MHz

This is my operating plan at present time. As you know KU2F/VK4 is now active from OC-187.
He says that best time/freq is 21z - 23z on 14MHz for EU and 11z - 13z on 14MHz for NA.

Anyway your suggestion and advice will be very much appreciated.
Lizard Island does not provide internet service in the room. It is only available in guest lounge.
Please do not send me direct e-mail or request message on DX spot during vacation because
I can not read anything online.   Stay tuned.....

JA1NLX/VK4 from OC-187 updated

This is primary antenna I expect. It consists of mini tripod, 4 antenna arms, LowBand coil and Long whip. All come from Buddipole. Max total length is about 5m. I have 1/4 wave length on 14,18,21,24 and 28MHz. 2.5m x 80 radials and various capacitors attached for better matching at feed point.
I used this antenna in FK/JA1NLX 2009 and JA1NLX/VK4 2010. It has worked very well with a little troublesome for band changing.

JA1NLX/VK4 from OC-187 updated

This room  is one of Sunset Point Villa which I booked. Maybe I have great sunset view !
I do not know whether I have good room for antenna setup. The antenna will be 5m long Buddistick 1/4 wave vertical for 3.5-28MHz or random wire with ATU.
Lizard Island Resort says HAM will be always welcomed if he/she set not big antenna up !
Stay tuned.....

JA1NLX/VK4 from OC-187 updated

VOACAP give us interesting propagation prediction chart.
Here are a few charts from VK4 to DL, OH, JA, W6 and W2 in August this year.

For DL

For OH

For JA

For W6

For W2

As you see I do not expect too much for EU and East coast of NA.  In Sept 2010 I operated JA1NLX/VK4 at Dunk Island, OC-171.  I found very limited opening for EU around 17z on 14MHz and almost no opening for NA.  The location was not good for NA though.
Your comment and advise will be very much appreciated.

A35AY Daily Topics

A35AY has been operated during Feb 3, 2011 21:00z and Feb 9, 2011 05:00z.
3800 QSOs has been logged (including many dupes) on 7/10/14/18/21/24/28 CW and 14/18/21/28 RTTY.

Fafa Island Resort is very nice for DX Vacation. Staff are very kind and helpful. They know HAM radio very well. They have 13 Fale (Bungarow). As this is just in off-season there were only a few family during my stay. I had almost private beach. They say the best season (for non-HAM) will be in September.
I had very strong wind almost every day. I used 4 rope to support fishing pole. You must take care to support Antenna.

As Internet connection was not available this page could not be updated. Following are daily topics.

Log has been uploaded on OnlineLog . Check your QSOs on OnlineLog. If you find any problem then please let me know.
Log will be uploaded on LoTW when these check will be done. I will QSL for ALL QSOs via buro (GlobalQSL) as usuall. If you need direct QSL then please send me SASE.
I think I answered all even if it was dupe. I know who has been logged 2 or 3 QSOs on same band/mode though...

You may be interested in my Antenna.
About 7.5m wire is wounded on 6.3m long fishing pole. This wire is directly connected to Antenna input of Z11 Pro ATU. 2.5m long radial wires (x80) and 5m long radial wires (x4) are layed down on the ground (beach). These radials are connected to earth input of Z11 Pro ATU. 40m long coax cable is connected between output of Z11 Pro ATU and Transceiver (via power meter). In my case 30m long coax is good enough though.
Z11 Pro ATU makes good match for all bands except 1.8/3.5. 7.5m long element is too short for these bands. Band change is very easy. You need to transmit 1 or 2 seconds.
At high tide water come in about 2m or so to Antenna pole. The beach is perfectly open for East-North-West.
You may say "That works well ?"  Yes it works very well on all bands. As you heard me my sigs was not strong but you heard me. Believe me I worked almost 3800 QSOs with this simple Antennas and 100w power.

Interesting pictures....

Day tour guest arrived
Sunrise at Fafa Island
My Fale and painting
Guest in my Fale
Sunset at Fafa Iskand

In the darkness I arrived Fafa Island Resort at 20:30. A lots of stars in dark sky. It took almost 30 Hours from my home in Tokyo....very tired !!!

With only some small lights in Fale I could not unpack my bags.
I found main electricty (240V) was not alive this time.  Everything tomorrow....

I got up at 06:30. OK it was sunny this morning. Although 240V has not been allive I begun to unpack bags and setup Eagle with PC and Antenna.

Manager said "Is this Antenna ?  It is too small !"
I supposed previously stayed HAM used much bigger Antennas.

At 08:30 I finished all setup without 240V.
I walked to restraunt and took breckfast. I asked manager to provide 240V quickly.
I founf another problem.....My laptop could not be connected to internet.....OH well !!!

When I was back in Fale 240V was allive !!!  All seemd to work OK except Eagle. Again Eagle was poor for RFI. I must reduce TX power down to 50 watts. I replaced Eagle to FT-857. OK it workd as usuall.

At 10:00 A35AY started on 17 meter CW after checking higher bands. 17 meter has been good with almost 420 QSOs. JA, NA, SA, VK/ZL has been logged for 4.5 hours.
At 14;30 after some QRX I changed to 20 meter and worked 160 QSOs, AS, VK/ZL, EU.

At 21:30 after dinner I canged to 30 meter. AS, EU has been logged. 30 meter seemed OK for EU too.
At 22:00 240V suddenly turned OFF !!!  I had no idea to ask manager at this time....Everything tomorrow !!!   This is real world in small island in Tonga.  Sorry for my sudden QRT.  I had no way to announce this QRT !!!

Logged about 630 QSOs on 15/17/20/30 meter CW today though....

It was my 67th birthday !!!  At 07:30 240V was ON. I asked manager to turn 240V ON and keep allive as long as possible.
It was bad above 15 meter. 17 meter was good in day time followed by 20 meter. 30 meter was good in late eveing.
Resort manager kindly provided "special" 240V today. It worked 24 hours !

Special 240V Line from somewhere !!!

WX was very bad today with rain and strong wind.
I started on 15 meter followd by 12 meter and 10 meter. 15/12 meter opened for both JA and NA/SA. 10 meter opened only for JA.
Fortunately I did not notice any man-made noise on each Band. Both big and QRP sigs could be easily heard. I have worked many QRP stations on each Band.
My simple antenna (7.5m wire on fishing pole with Z11 Pro ATU, a lots of short radials on the beach) has worked very well on each Band. It was very easy to change Band, simply trarnsmitting QRP carrier.

WX was sunny again with wind, not bad.
I tried 30 meter in mid-night and worked many EU, NA and JA. In the morning I operated RTTY on 17 meter, my first attempt. I worked about 130 QSOs, mostly W but some XE and YV.
In the afternoon condx was poor, no opening. In the late evening after dinner I tried 30 meter again. Condx was very good for all over the world. I worked many EU, NA and JA.

Condx was poor on high bands in the morning. I worked RTTY on 10/15/20 meter with not many QSOs.
In the evening after dinner I tried 40 meter. 40 meter opened NA, JA and EU at same time. I have operated all bands except 80 meter with total 3400 QSO. This was my record !!!

This was the last day for A35AY.
Thanks to all staffs in the resort I enjoyed A35AY operation very much with unexpected result. Finally 24 hours operation was possible.
I decided to check Eagle again today,

Bad sidetone click noise by RFI can be noticed remarkably on 10 meter. It seemed almost OK on other bands. I workd a lots of NA and JA on 17/15/12 meter CW with Eagke. I found no serious problem except side tone click on 10 meter. Strong sigs and weak sigs can be heard as it is. It is just like "AGC OFF" I could pick up each sigs very easily. When I received a few stations calling me on almost same freqyuency sometimes noticed a little distortion. I do not know what it was.

At 18:00 (05:00z) A35AY closed. I made about 3800 QSOs (including many dupes as usuall) during this vacation. It was my new record.
Internet connection was not available with my laptop computer. I do not know why but I could not connect to wireless Lan in the resort.

I enjoyed last night in Fafa Island, looking satisfied !!!

I left Fafa Island at 16:30 for international air port in Tongatapu Island. It took almost 1 hour by boat and car. I arrived at Auchland in the late evening and stayed at Holiday-Inn Auckland Airport for one night.
