- License for both location

 I had contacted TCSI, Telecommunications Commission Solomon Islands, about middle of Dec. 2017 and got a response with a notice that the office will be closed for a month until Jan 15 for Holiday break. Yes, one month break for Holiday. And also be noticed my applications will process after the break. I worried the applications will issued on time as I had experiances many kind of services were delayed in South Pacific. Second concern was they don't accept wire transfer to pay process fee so I have to pay in person and my arrival day at Honiara which is the capital and TSCI office is located in will be Saturday. That means I won't be allowed to operate until Monday (2/26) so I asked to Aaron, the manager, to issue license before the arrival and will pay the fee on Monday in person. After several emails, he finnally issued and emailed my license on Feb 4. He is so nice and generous person. Now I can QSO on Saturday and Sunday as well. 

- Antennas

 I started to plan this trip since last November. There are lots of thing to do such as flight booking and looking for accommodation which is good for installation antennas and electricity availability also amateur radio license from the government. 

 Most fun part is preparing antennas. There are so many type of antennas and all the DX locations are in different situations and it is just one man Dxpedition so antennas have to be chosen very carefully. One of my friend recommended VDA (Vertical Dipole Array). He mentioned this antenna is very easy to handle by one man and great efficiency when installed near water. I realized this antenna was used for many DXpedition but mostly mono bander. I didn't want to bring mast for each band so decided to make it dual bander 20/15m and 18/12m. Please see the picture which is for 18/12m VDA. The SWR for both bands are not perfect but lower than 1.7:1 at my backyard. I think the SWR will better when it installed near beach.

 I got several request emails to work on 160, 80 and 60m bands. Actually, I don't have any experience to operate 160 and 60m before. Especially, 160m antenna is almost imposible to install at my small backyard. Some of folks got me an idea to hang a long wire on the coconut tree to install an Inverted-L but I was not sure. I used to use a 80~10m End-Fed from Myantennas on my last trip to Vanuatu,  and was very happy with it, so I sent an email to Danny from Myantennas.com and got a recommandation an End-Fed antenna (EFHW-16040-HP) for 160 to 40m. I will bring the antenna with me for the bands. Hope it works well for the Top Band and 60m.


Update, 22 Feb 2018

I am in YVR now and one big golf bag has checked-in to ship to Nadi, Fiji but not Honiara in Solomon Islands. I don't know why but I have heard that the bag needs to be picked up and re-checked in at Nadi to send to Honiara again. The shipping will be paid saparately so the cost will be almost double. Anyhow I am on the way and will be Honiara after 27hrs later from now.


Update, 27 Feb 2018

I am in the domestic airport of Honiara to fly to Lata in Temotu Province (H40). The Internet connection was very not good at the lodge in Gadalcanal so I couldn't be connected to the Internet. I will post the story in Gadalcanal later. 


Update, 5 Mar 2018

The Internet is  extreamly slow in Lata so connecting to QRZ.com is almost impossible. Only email and texting are available but it alse takes time to receiving and sending.

During the days, 4 antennas has installed. GP (40~10m), End-fed (160~40m) and 2 VDA (20, 17m). I took pictures but couldn't upload the images because of the extreamly slow Internet speed, even uploading QSO log file was failed every attempt until I found zip file can be uploaded to Clublog. The zipped log file for H40 has been uploaded yesterday in the morning. It will be uploaded to Lotw after certification files for both H44 and H40 aquired. 

Please don't hesitate to let me know if you couldn't find your log on Clublog then I will look for my log file and correct it if needed.

It took more than an hour to upload this short story and not sure it will successfuly posted or not. :-/
