Author Topic: Transatlantic QRPp with a "simple wire" antenna?  (Read 9080 times)

Hi, all,

After working an AA6 on a tenth of a watt, I'm wondering if it's possible to go across the pond on that power. My antenna falls under the "basic wire" category of the NAQCC; Skyblaster Yagis are out at my QTH.

Can it be done?

Has it been done?

How has it been done?

Google,[QRP milliwatt distance records] and you will see it can and has been done with a lot less  than 1/10 watt. If you make it to 6 land from 2 land with your 1/10w  you should have no problem getting over to GB/Europe (lots of flat salt water between).Of course propagation/grey lines are key in doing this. I've never tried the milliwatt thing but from my QTH in Maine 2 x qrp to West coast and Europe is a daily occurrence with 1-3 watts on 20m with either a hex or windom both at 25 ft. If you are in the N.Y state area for this time of year try 14.060-.065 between 0430 and 0630 LT to catch the European qrp boys working the morning  grey line to the states .Check out [QRPSPOTS.com] to see what bands are open to where from stations in your area.

Made it to France today.

Then my neighbor Gerry N2GJ told me he got the Marshall Islands with the same power.  Grin

Onward!

Yup. Must have answered about ten Gs Fs, PAs, and DLs who were calling CQ DX before I found one with good ears.  Wink

I did get some grayline going -- worked a GI with 5 watts after trying him three times with 0.1 -- -- but the propagation really wasn't there until later in the day.

I tried milliwatting with an 86 ft open wire fed dipole and a 33ft end fed vertical from my 2nd floor apartment in the 1989 ARRL DX CW contest--made about a page (50) of contacts on 10/15/20 with powers ranging from 48 to 96 mW.  The Europeans were the easiest to work at that power level.  I also recall doing something similar on phone, working the big gun stations that heard well.

I worked DXCC (and have the QSL cards) running a Sierra between .7 and .9 watts to a windom. (I'm assuming QRPp defined as less than a watt.) I have never attempted to go below half a watt.* I started when this cycle was first peaking. 10, 12, and 15 meters were big contributors with 10 the major one. 17 and 20 meters had contacts. 30 and below a bit rough. I think I made 1 on 30. I worked as far away as ZL and VK from here in east Tennessee. Europe and west Africa were easy shots. I applied for the NAQCC DXCC milliwatt award but never heard got a response, and really forgot about it until it was mentioned here.

My QRP buddy down the road, NV4G, has worked several countries running a tenth of a watt using a similar windom and has made trans-Atlantic QSO's.

*I've worked several EU countries running my 20 meter Rock-Mite (500 mW) to a HF5B.

I would think a high band dipole at the appropriate height and in the right direction (and paying attention to propagation) would yield many QRPp trans Atlantic QSOs from the eastern US.

As far as "Life is too short for QRP", power is no substitute for knowledge, skill, and efficiency.  Grin

I've done QRPp on 6M and 2M with propagation helping and it was fun.
My best there is a CT1 Portugal from a KU4AB square loop on the
mobile at 4W. For QRPp A W8 near Chicago on 800mW on 6M and
it was a 25 minute QSO.

On HF my nominal power is 3-4W from my 10M, 20M and 40M SSB radios
I've homebrewed have great fun with them.  My favorite pastime on HF
is busting pileups with the 20M.  I do it because everyone told me early on
that I could not do anything on 20M without an amp(kw).  Takes patience
and getting the feel for what the other guy can hear.  You have to listen.
More often than not they can hear, if, you can get in between.

It all about the antenna.
One thing on antennas, a good dipole up high, is everything and certainly
the simplest antenna.  Properly trimmed it does not need a tuner and will
give the best possible efficiency.  If you can swing it a wire beam will help
a lot.

Due to health issues, my wife needs my assistance--so I really need to be in and out of a pileup in about 5 minutes or so--I can do this routinely with 100 watts, something that often isn't possible with 5 watts.

I did work

(interruption) Vlad in Egypt with 3 watts for a new country 2XQRP two weeks ago, so I haven't entirely gotten out of QRP--think it was number 54 or something like that.  Maybe I'll put up a beam and tower and get the last 40 or so after it starts getting hard to find DXCC challenge points--there are a lot of countries I can work on 6 and 160 meters with 100 watts.

My last two QRP awards were 2XQRP WAS and working 1000 QRP ARCI members 2 way CW.

IIRC, I did around 50,000 miles/watt on 5760 MHz over a Line of Sight Path from Mt Wauchusett to WB1FKF.

Zack, that 2XQRP SU contact sounds like a nice one as does your 54 score. I have seen a QRPer in HZ land spotted but have been unable to find him before he's spotted.
I've worked 39 countries 2XQRP, mostly EU and the Caribbean area. But some neat ones were OK1AEX/5N0, A33A, and ZS6QU.

I had a stroke and missed a solar cycle working on important issues, like regaining my fine motor skills so I can keep a paper log and send CW with a paddle.  The last little hurdle--I got over by learning to throw darts...  But, 8000 QSOs later, my writing is as good as it has ever been.  Even better, my operating skills have improved to where I can make DX and contest contacts easily again. Grin
