YN5Z operations are by Scott/K7ZO. I will be using YN5Z again for my Nicaragua operations during 2016. Thanks to the Telcor licensing team in Nicaragua for issuing me the callsign valid for the full year as well as granting my request for a 2X1 call. Also thanks to Octavio/YN2N for his assistance in getting the paperwork processed. (I used YN5ZO during 2012 and YN5Z during 2013, 2014, and 2015.)

Please see the bottom of this page for QSL information.

Information on my 2016 Operations

My next operation will be around the CQ WW DX SSB contest in late October. I will be making a Single Operator All Band High Power entry in this contest. I hope to be on the air some before the contest as well -- in particular October 27th on the WARC bands as well as RTTY.

My first trip to YN in 2016 was in late February and early March. I was able to participate in two contests. The first was the NAQP RTTY contest on Februay 27 and 28. This is likely the first ever entry from Nicaragua in this contest. The story of this operation can be found at: 2016 NAQP RTTY Story at 3830Scores.com. The second contest was ARRL DX Phone on March 5 and March 6. I ended up in 5th place among all DX stations. The story of that operation can be found at: 2016 ARRL DX Phone Story at 3830Scores.com I also made about 650 non-contest QSOs during this trip including a few with National Parks on the Air activations in the USA. All logs from this trip have been uploaded to LOTW and QRZ.COM.

Information on my 2015 Operations

My second and final operation during 2015 was around the CQWW SSB contest on October 24 and 25. The story of my CQ WW SSB contest operation can be found at: 2015 CQ WW SSB Story at 3830 Scores.com. I made 6,579 QSOs during the contest and another 588 in pre contest operation. There was no operation after the contest. The operation is complete and I am back home in Idaho. The log was uploaded to LOTW and QRZ.COM on 1 November. I am currently replying to direct QSO cards and, upon receipt, should have the reply card in the mail the next day.

My first operation during 2015 was in July during the IARU contest. I made about 1,400 QSOs during the contest and another 500+ QSOs outside the contest. This operation is complete and my logs have been uploaded to LOTW and QRZ.COM as of 17 July. I am currently answering direct QSL cards.

Information on my 2014 Operations

My final 2014 operation was during the ARRL 10 Meter Contest. I operated as Single Operator, Low Power, Phone Only in the new Unlimited category. Unfortunately my amplifier died sometime between CQWW SSB and when I turned it on for this contest so I had to operate low power. I also suffered through a 6 hour power outage on Saturday. Still my results were good enough for a 1st Place World. My short score and story can be found at: http://lists.contesting.com/archives//html/3830/2014-12/msg02379.html I also made 127 QSOs outside the contest on SSB and RTTY. The log for all my QSOs were uploaded to LOTW on 21 Dec 2014.

My second 2014 YN5Z operation was during the CQWW SSB contest where I operated as a Single Op All Band High Power entry. My score and story can be found at: http://www.3830scores.com/showrumor.php?arg=WBa5z3fivvcfR. Logs have been uploaded to both LOTW and the QRZ.COM logbooks. I ended up placing 14th in the World and 8th in North America. That is pretty good for a temporary Field Day setup!

My first 2014 YN5Z operation was during the ARRL DX Phone contest.  You can find my writeup of the contest at: http://3830scores.com/showrumor.php?arg=x8axzBffvffc1. The log has been uploaded to LOTW and QRZ.COM. Final results have been posted and I came in 4th place SO HP from DX. Thanks everyone for the QSOs.

The YN5Z Station

My YN5Z station is a total Field Day operation with me putting the antennas up and wiring everything together before every contest and then taking it down immediately after. The full station takes about 1 1/2 days to put up and 1 day to take down. The station is composed of:

  • A 5 band Spiderbeam antenna and their 10M pushup mast and tripod. This is connected to the amp with 100 feet of LMR-240. The antenna is stored in one hard sided golf case and the mast and tripod in a hard sided ski case since the mast is just a bit too long to fit into a golf case.
  • A full size 1/4 wave vertical for 40M with 32 thirty foot long radials. This is connected to the amp with 125 feet of LMR-240
  • A aged HF2V top loaded with three 15 foot wires for 80M and 160M. Also with 32 thirty foot long radials. This is connected to the amp with 150 feet of DX Engineering RG-8X. The verticals are stored in another hard sided golf case.
  • An Elecraft KPA-500/KAT-500 amp, tuner, antenna switch set
  • A Kenwood TS-590 with SEC switching power supply.
  • Heil Proset and Boss Footswitch
  • A microHAM microKEYER II
  • WriteLog Contesting Software
  • An ASUS Ultrabook PC.

A short video tour of my Nicaragua QTH and operating position can be found at: http://vimeo.com/78274328 I took this the morning after the 2013 CQ WW SSB contest.

Information on my 2013 Operations

My 2013 YN5Z operations are complete. If I worked you in a contest thanks for the QSO. All logs have been uploaded to LOTW and QRZ.COM and I am replying to all cards received direct and the buro. See below for QSL information.

I operated in Nicaragua as YN5Z three times during 2013 around specific SSB/Phone contests. I am a contester at heart and the motivation for my YN5Z operations is to be sought after DX in major contests leading to high rates and scores.Yes, I am a rate junky. My goals were to place in the Top 10 in my category with essentially a Field Day operation. Outside of the contests I also get on the air for more casual QSOs as well as some dxpedition class RTTY. Unfortunately you won't find me on CW as I am just not that good a CW operator.

These contests were as follows and with a link to my write-up about the contest.


I QSL 100%. My preferred method is via LOTW or the QRZ.COM log book. I do not use eQSL. I will also gladly provide a paper QSL for those that want one. You can obtain one via the buro or direct. Direct QSL's should go to my K7ZO address in QRZ.COM, not to Nicaragua. If you want a reply direct please include a SASE or SAE and Green Stamp or IRC. My preference is for $1 even though US Air Mail stamps currently cost more than that. I will make up the difference as part of my Ham Spirit. I can also accept payment for return postage via Paypal. Send me a direct e-mail if you would like to do this. IRC's are strongly discouraged. Any card received direct without return postage will be returned via the buro. Also any card received without a return envelope will be returned via the buro. I don't have the time to individually address envelopes.

As a note to operators outside the US sending me a SASE -- you need to place $1.15 of postage on the envelope, This is the current cost of an airmail stamp in the US to foreign addresses.

As a note to US operators you can use the ARRL Buro system to send me your cards and I will return them via the buro as well.

I am processing direct cards the same day they are received. So, the reply card goes out the next day. I have processed all buro cards received and return cards have been send to the ARRL Outgoing QSL Bureau.

10 November 2014 update. Mailed cards to the ARRL outgoing bureau. Most of the cards were from 2013 contests - notably CQWW SSB and ARRL 10 Meter. If you want to know if your buro card has been received and replied to drop me an e-mail.

6 May 2015 update. Received 56 cards from the W7 Incoming bureau. Most were from 2014 CQWW SSB and ARRL 10 Meter contest and from the countries of F, DL, S5, and I. These reached me very quickly in only 6-9 months after the QSO. Reply cards were sent to the ARRL Outgoing Bureau on 8 May.

28 August 2015 update. I received 41 cards from the W7 incoming bureau. Most were from the 2014 CQWW SSB and ARRL 10 Meter contests and from the countries of DL and EA with small numbers from other European countries. Reply cards will be sent to the ARRL Outgoing Bureau by 4 September 2015.

05 December 2015 Update. Over the last month I received 58 QSLs from the W7 incoming bureau. Most were from the 2104 CQWW SSB contest. About half were from Japan and half from Europe. They will be sent to the ARRL Outgoing Bureau next week. I am current on direct cards. All received have been replied to.

26 April 2016 Update I just finished processing 122 buro cards I have received over the last two months. Most are from Europe. About 25% are from 2013, 50% from 2014, and 25% from 2015 QSOs. They will be sent to the ARRL Outgoing Bureau next week. I am also current on direct cards. All cards received have been replied to.

25 February 2017 Update. I received yesterday a large envelope of buro cards for K7ZO. There are many many cards in there from USA stations QSL-ing "YN5Z via K7ZO" going back to 2013. For some reason it looks like some of these cards have taken 3-4 years to get to me. I will send reply cards to the outgoing buro within a couple weeks. Sorry it has taken so long for those cards to arrive.

Of the 47,596 QSOs I have made as YN5Z I have received 1,751 paper QSL cards. 962 of these were direct and the rest from the buro. Additionally 28,714 of these QSOs, or 60%, have been confirmed via LOTW.
