QRP 365 Update 4

January 25, 2015 Leave a comment

It’s Sunday January 25th 2015 and I have now completed week 4 of my QRP 365 Challenge.  For those who are new to this, this means that for the whole of the year, 2015, I shall use no more than 5W and just CW or Datamodes, no phone at all.  At least one QSO a day – hence 365.

So how did I do this week?

19/01/15: LY1CZ, 5W, PSK31 on 21.07015MHz, a distance of 1000mi (1613km) / 200mi (322.6km) per Watt.

20/01/15: UR3ES, 5W, PSK31, 14.07015MHZ, a distance of 1508.7mi (2428km) / 301.74mi (485.6km) per Watt.

20/01/15: RU3XJ, 5W, PSK63, 21.07015MHZ, a distance of 1851mi (2985km) / 370.2mi (597km) per Watt.

21/01/15: OE4BHF, 5W, PSK31, 21.07015MHZ, a distance of 842mi (1358km) / 168.4mi (271.6km) per Watt.

21/01/15: LY2FB, 5W, PSK31, 21.07015MHZ, a distance of 905mi (1460km) / 181mi (392km) per Watt.

22/01/15: RV3WL, 5W, PSK31, 21.07015MHZ, a distance of 1553mi (2505km) / 310.6mi (501km) per Watt.

23/01/15: IK2WAS, 5W, PSK31, 14.07015MHZ, a distance of 647mi (1044km) / 129.4mi (208.8km) per Watt.

23/01/15: UR5ZEK, 5W, PSK63, 14.07015MHZ, a distance of 1490mi, (2404km) / 298mi (480.8km) per Watt.

24/01/15: RN1TV, 5W, PSK31, 21.07015MHZ, a distance of 1286mi (2075km) / 257.2mi (415km) per Watt.

24/01/15: DK0GHC, 5W, PSK31, 14.07015MHZ, a distance of 557 mi (898km) / 111.4mi (179.6km) per Watt.

24/01/15: UA9CLR, 5W, PSK63, 21.07015MHZ, a distance of 2412mi (3890km) / 482.4 mi (778km) per Watt.

25/01/15: R4WG, 5W, PSK63, 21.07015MHZ, a distance of 891mi (1437km) / 178.2mi (287.4km) per Watt.

25/01/15: ES3BR, 5W, PSK31, 21.07015MHZ, a distance of 1056mi (1704km) / 211.2mi (340.8km) per Watt.

25/01/15: US5LPO, 5W, PSK31, 14.07015MHZ, a distance of 1616mi (2607km) / 323.2mi (521.4km) per Watt.

As can be seen the best DX this week was UA9CLR with a cracking 2412 miles (3890km) worked. I have also had the disadvantage this week of suffering from a severe head cold combined with a chest infection that makes concentration very difficult.  However, although it isn’t obvious from the above logs, I have also spent some time on 40m, 30m and 20m CW calling CQ but to no avail.  If you do hear me, please do reply.  It may only be a weak signal and it may be a bit slower than you are used to (around 16wpm) but we don’t all just listen for fast, high power signals I am sure.

I do believe that the biggest challenge I face at present is finding the time to set aside every day in order to have at least one QSO.  For this reason I can only, generally, be heard early in the morning between 08:00 and 09:45 so if you are around during this time and you do hear me calling CQ on either 40m, 30m or 20m in the CW portion of the band please do reply.

Until next update..

Next update will be on Sunday 1st February 2015.

As can be seen the best DX this week was RA1QLC with a cracking 1601 miles (2582km) worked. Today (18/01/15) there was a CW contest filling the bands but they didn’t seem to wish to work a QRP station sending QRS at 16wpm.  I did spend some time calling CQ on 7.030 and 14.060MHz but had no replies either time.

I do believe that the biggest challenge I face at present is finding the time to set aside every day in order to have at least one QSO.  For this reason I can only, generally, be heard early in the morning between 08:00 and 09:45 so if you are around during this time and you do hear me calling CQ on either 40m or 20m in the CW portion of the band please do reply.

QRP 365 Update 2

January 11, 2015 Leave a comment

It’s Sunday January 11th 2015 and I have now completed week 2 of my QRP 365 Challenge.  For those who are new to this, this means that for the whole of the year, 2015, I shall use no more than 5W and just CW or Datamodes, no phone at all.  At least one QSO a day – hence 365.

So how did I do this week?

05/01/15:  UR3ES, using 5W PSK31 ON 14.07015MHz a distance of 1508.8miles or 2428.1km. That’s 301.76mi(485.62km) per Watt.

06/01/15:  R3DOM, 5W, PSK31 on 14.07015MHz, a distance of 1581mi (2550km), 316.2mi (510km) per Watt.

06/01/15:  HB9DAX, 5W, CW on 14.060MHz, a distance of 609mi (979km), 121.8mi (195.8km) per Watt.

07/01/15:  ES3RM, 5W, PSK31 on 21.07015MHz, a distance of 1056mi (1704km), 211.2mi (340.8km) per Watt.

08/01/15:  DF1OA, 5W, PSK31 on 14.07015MHz, a distance of 465mi (750km), 93mi (150km) per Watt.

09/01/15:  SP5NHK, 5W, PSK63 on 21.07015MH, a distance of 843mi (1360km), 168.6mi (272km) per Watt.

10/01/15:  LY2FB, 5W, PSK63 on 21.07015MHz, a distance of 905mi (1460km), 181mi (292km) per Watt.

10/01/15:  RC3C, 5W, PSK63 on 21.07015MHz, a distance of 1521mi (2453km), 304.2mi (4906km) per Watt.

10/01/15:  US5LPO, 5W, PSK63 on 21.07015MHz, a distance of 1616mi (2607km), 323.2mi (521.4km) per Watt.

11/01/15:  UT7CA, 5W, PSK63 on 14.07015MHz, a distance of 1420mi (2290km), 284mi (458km) per Watt.

11/01/15:  UR3ES, 5W, PSK31 on 21.07015MHz,  a distance of 1508.8mi (2428.1km),  301.76mi(485.62km) per Watt.

As can be seen the best DX this week was US5LPO with a cracking 1516 miles (2607km) worked.  May not be record breaking stuff for the large, high power stations with monoband beams but for 5W into a wire dipole it certainly is an achievement.  What can also be seen so far is that 5W of Data (PSK) seems able to carry further than 5W CW.  However, this is still early in the year and things may change.  One thing I have noticed is that there is far more activity on the data portions of the bands than on the CW portions, esp the QRP section of the CW portions.

Next update will be on Sunday 18th January 2015.

 

QRP 365 Update 1

January 4, 2015 1 comment

04/01/2015:

It’s Sunday, start of a new week, so how’s the QRP 365 challenge going so far?

I started this challenge on 01/01/2015 with a QSO using PSK63 on 20m with S56IPS at a distance of 874.3 miles (1407.1km) or 174.86 miles (281.42km) per watt.

On 02/01/2015, I had a CW QSO with Chris, G4AJA,  at a distance of 99.9 miles (160.8km) on 40m.  this works out at 19.98 miles (32.16km) per watt.

On 03/01/2015, it was back to using PSK63 and a QSO with SQ85PZK on 20m at a distance of 908.3 mi (1461.8 km) or 181.66 miles (292.36km) per watt.

Today I spent some time calling CQ on 20m CW with no reply, then went to 40m CW, again no reply and finally to 30m CW, still no reply.  After an hour of fruitless calls, I switched to PSK31 on 20m and put out a CQ.  First reply was from SQ3BKH (719.3 mi (1157.6 km)), then DM5KK (599.6 mi ( 965.0 km)) and finally from DF2IAC (501.4 mi ( 806.8 km)).  So the best result today was 143.86 miles (231.52km) per Watt.  Not the greatest of distances but pretty decent when only working with 5W.

The challenge goes on. Next report will be on 11/01/2015.

The 2015 QRP 365 Challenge

This year I have set myself a challenge.  That is, every day I shall aim to make at least one HF QSO, on any band from 80m – 10m, and this shall be using very low power, or QRP.  In fact, I shall use no more than 5W.

All this is fine but it does mean that I shall need to pick my mode of operation and times to suit best.  Generally this means using a very narrow mode of operation such as CW or data.

CW is a mode that I have used little over the years since taking a 12wpm test in 2000 to get my HF licence, and even less since having a stroke in 2013.  However, my dear wife kindly bought me a new iambic twin paddle for Christmas so I am determined to get back into using it properly again.

In fact I now have a line up of  2 iambic paddles – one from Kent and one from MFJ plus a straight key of unknown origins (I believe it was from France). These can be seen in the picture below:

Anyway, I made a start on the challenge on Thursday 1st January 2015 and worked S56IPS using PSK63 – a data mode – on 20m with 5W and 599  each way.  On Friday 2nd January I worked G4AJA on 40m using CW, again with just 5W this time with a RST of 578 each way.  Not bad considering how “rusty” my CW has become.
