Hello Kamal,
Great to work you on 17meters two nights ago. My second contact with 4S7 ever ! Your signal was quite strong and easy to copy. I look forward to working you again.

Hello Kamal - Nice to work you again! TNX for our recent 17m CW QSO on 26 June 2024 @ 01:53z. You were easy copy with a nice signal on my Hexbeam up at 10m high. Well done with your 4 el yagi and 100w! Our 1st QSO back on 10 Oct 2016 @ 11:45z on 30m CW was quite amazing for me...just an 88' wire doublet up at 13m high using my usual 100w for me (and you using a 2 el Quad beaming LP!). TNX for your commitment to DXing from 4S7-land.!! Perhaps someday you will consider using the log upload services of Club Log, QRZ.com and even LoTW. For now, wishing you and your family the very best!
73 & good DX, Bill W1WBB

Kamal.....It was such a nice surprise to work you last night on 17 meter CW! It has been many years since I have heard 4S7. I am running 1500 watts but my antenna is not the best. I am using a ground-mounted vertical with no radials. I definitely would like your QSL card as I do not have one for 4S7 on CW. 73...Brad, NG2X

Hello Kamal, I was very excited to work you on FT8 today. Our QSO is the furthest QSO I have made east bound from my QTH. I have a Yaesu FTDX10 that I run barefoot with a Hustler BTV6 vertical. I have the additional 12 and 17m bands as well. Best 73 de Ed K3ENV

I am looking to build a 100% solar powered station in the UK, for remote operation from Singapore so inspiring to read about your experiences.

Hi Kamel, I was very pleased to work you on 17m cw. My station id a Kenwood TS590 sg and an Ameritron AL 811 at 300 watts. My modest antenna is an 80' long end fed wire hung in some trees about 15 ft.high.
I hope to get your qsl and hopefully a QRZ or lots confirmation. I need that for awards.
It was great receiving your email.

Tnx for FB QSO on 17m CW. Conditions were good, but your signal was exceptionally loud. I use an Elecraft K3 with an Ameriton amp running about 1 kW to a SteppIR DB-18E with 3 elements on 17m. It's up 95'. Hope to cuagn soon. Vy 73, Joe

Thanks for my ATNO and a second on 17 meters CW. My station is very modest. Yeasu FT-857D with no amplifier into a home made EFHW in my tree, mostly vertical. Hope to hear you as my ATNO on SSB someday. 73.

Kamal, thank you for your email. Yes I enjoyed our QSO too. I operate remote using antennas and rigs from Remote Ham Radio.com. They have really good sites all over the US, mainly on the East and West coast. The station I was operating today was their Blueberry Hill site in the Hudson River Valley of New York State. The radio and amp there are Flex equipment to a GXP 11-5 yagi. I was QRO legal limit. 80 feet up. I used to live in a condominium which did not allow any antennas at all so I got into remote operation for most DX. I am now in a new home with much less restrictions but must negotiate antenna ideas with my XYL. I will send you my QSL card.
Thanks for your email,

Thanks for the QSO and email. I now see that I should not send a QSL via the postal system. I checked my log and we have several other QSOs on CW, SSB and FT8. 73!
