The Completed K1

Thanks to Don Wilhelm, W3FPR, and Stan KF4BY, my K1 is complete and making QSOs.  My K1 has the K6XX tuning indicator installed.

Snow Weekend - Great Weekend for QRP

This past weekend - winter storm Jonas hammered the east coast with snow and ice.  I was snow bound at home for 3 days.  We lost power for 6 hours on Friday.  The great thing about QRP is that you can run forever on batteries and solar.  I made a big dent in my QRP Challenge QSOs with propagation being good.  I made a total of 26 new DXCC's for a total of 55.  The past three days was equivalent to the first 23 days.  Now that I am back working again, propagation has not been good on 40m with too much QRN in the evenings when I am home.  Notable contacts from the weekend were Hawaii AH6V, and Alaska K3Y/KL7.  I was really surprised at the Alaska station coming back to me on 17m with my measly 5 watts.  Also notable was the contact with Rodriguez Island 3B9FR at over 2000 miles per watt, and Kenya 5Z4/DF3FS.  The last 50 will be tough though.  I have purposefully limited my mode to CW for now.  We will see how far we get with that approach.

Don Wilhelm repaired my K1 and installed the K6XX tuning indicator.  I should have that back by the weekend or Monday at the latest.

Dave Anderson K4SV completed his challenge and Vlad N3CZ is almost there at 93.  My rotor got frozen and would not turn the hexbeam.  Fortunately it was frozen towards South Sandwich for all time new one at #288.  I also received my card from Mount Athos - SV2ASP/A from Monk Apollo.  That was a great moment cherishing that hard fought contact.  Mexico XE2B was on this evening but would not hear my small signal in the QRN - live to fight another day.

Antenna for QRP Portable Operation and CC&R Challenged - NY4G Inverted L


Multi-band coverage 40-6 meters
Near the performance of a dipole on 20m-10m
Better than a ground plane vertical on 30m
Equivalent to a ground plane vertical on 40m
Portable - system weight - about 8 lbs  including tripod and mast
No need for trees
Set up time - 15 minutes or less

Some images from the presentation I made to the South Carolina DX Association.   The reference for comparison is the half wave dipole at half wave length AGL as shown by the slide below:

The first configuration for the inverted L is the one that should be employed near the ocean to take good advantage of the ground characteristics and the ocean's reflectivity.  Theses are the results of my models using EZNRC 5.0

The next configuration is that which should be employed in general away from the ocean - parks, at home, etc.

The following slide shows the schematic arrangement of the antenna for general purpose use.

Detailed instructions

Well the final question is - does it play in real life?

A side by side comparison against conventional antennas - a hexbeam and a full size ZS6BKW at 50 ft in an inverted Vee

The following is a video of a QSO with the Azores with me transmitting at 5 watts on a KX3

Day 6 of QRP Challenge - 86 to go

QSO with Panamanian Station HP3/VY2SS.  This is not a new one but a dupe of #6.  I am still at DXCC #13.  In the evening, after working on my K1 some, sat down and tuned around 40m and found the Venezuelan station YV5IUA not very busy - but he had a steady stream of stronger stations that he kept answering.  It nearly 5 minutes before he could copy my full call.   Finally made #14.  They sure are hard to come by.

Day 5 - Slim Pickin's Again - 87 to go

Just one QSO today with the Dominican Republic Station HI3TEJ on 17m CW.  This is DXCC #13

Day 4 - Slim Pickin's today - 88 To Go

With QRN high on 40m and me getting home late - my only contact was DXCC #12 6Y4K early in the morning on 40m.   He was a rather strong station and the exchange was quick and short.  I wish they were all like that instead of the knock down drag out ones that take forever to complete.

Day 3 of QRP Challenge - 89 to go

DXCC # 9 was with V44KAI in Saint Kitts.  This was also not an easy and short exchange.   

DXCC #10 was with VE3CX in Canada.  This was during the RTTY Roundup.  There were plenty of DX stations to call but few were able to copy my tiny signal.  The mode was RTTY

DXCC #11 was with C6ANM in the Bahamas, late in the evening on 40m CW

Day 2 - Three More - 92 to Go on QRP Challenge

DXCC #6 was with HP1IBF - and was a long drawn out 8 minute plus attempt at a QSO which finally succeeded at the end.  My fist or my brain finally broke down as I stuttered my way through.

DXCC #7 was with WP4L in Puerto Rico and this was more of a routine QSO

DXCC#8 was with PV8ADI in Brazil.  At first he did not want to do nything with me and just kept saying OK.  20 minutes later - he dug me out of the noise and worked me.

One of the things that one will realize when attempting to DX with QRP is that what is essential are several things that must happen simultaneously (1) Persistence and tenacity on the part of the QRPer (2) patience on the side of the DX to stop, try to dig you out and also be persistent on his end (3) Propagation and signal strength must be sufficient to support the copy of the signals.  If any of the above does not happen, the QSO does not take place.   It takes practice and judgement when the QRPer should give up on the QSO and cut his losses.

Some of these did not count - the one with VE3UTT was with the wrong call sign on my end.  The one with SP3DOF had the wick turned up to 10 watts.

Day 1 - Five Down and 95 to Go

The QRP Challenge has started for me and 10 others.

Right around 00:00 UTC the geomagnetic storms made for bad conditions and the DX cannot hear my answers to their CQ.  I resorted to calling CQ myself to see who would answer.  The result is K5NOF answering my call. This is DXCC #1

The following morning still on the first day - made DXCC  #2  to Slovenia.  This was an easy exchange as noted by the shortness of the video.

DXCC Number 3 is to France F5IN and was also a rather easy one in the video below:

DXCC Number 4 was with Antigua and Barbuda V25LK and took four minutes before he even acknowledged me.

DXCC Number 5 was with the Canary Islands with a German Operator EA8/DH2MS.  This was a knock down drag out fight.  It took 4 minutes before he even acknowledged me.
