Military tower finished

Posted by sm2wmv on October 6, 2013 Comments Off

The tower work in the military tower is now finished. All antennas are up and connected and they seem to work as expected. Some work is left to do on getting the tower rotational and also the jumper cables are needed between the ground and tower. SM2UVU made a contactor box which will be used for the rotation but I need to get hold of 100m+ of multi-conductor cable. SM2LIY, SM2UVU, SM2XJP and SM2XLL has been helping during the last two weeks to get the tower done.

The 40 and 20m antenna systems are now built up as the plans said a few years ago. Next year plans are to add a tower to the inband position for S&P on the run band and also trying to get the 60m tower up. Most of the house work was put on hold this summer and autumn, so that need to be finished next year as well.

2/2el for 40m @41/21m, 5/5el for 20m @38/24m, 3el for 30m @31m all homebrew design.

Not a planned effort and the first RTTY contest at SJ2W. I made a cable for the
TI-5 interface on Friday evening and we were planning on testing it a bit. It
ended up with an effort more of DX mode type than a serious M/S effort with no
mult radio, so I believe we lost a lot of RUN QSOs because of chasing mults.
SM2LIY did most of the operating while I was out working on getting the station
ready for CQWW SSB which also included a trip to SK2AU to change the coaxes in
their tower. However I did a few hours time to time when SM2LIY needed some
rest and I enjoyed it, so we might be doing some serious RTTY in the future as
well.

We enjoyed the excellent propagations, can't get much better than this with
these kind of SFI numbers, 15m was THE band. Hopefully the same type of
propagations show up in the CQWW SSB in a month.

It was also fun to follow the battle between our northern friends OH8A on
cqcontest.net

This was fun!
Had the opportunity to work the contest this year again from the nice station
SJ2W, thanks Mike. Was in the NTC team for Sweden, and was fun to watch the
race on cqcontest.net. My goal was to put in a new SOABHP SM record, old record
was by Rainer 7S2E from 2002, and goal achieved.
First time with N1MM and SO2R so was a bit rusty in beginning, made too few
moves in beginning so lost many mults in comparision to OH2BH and OH8X.

The conditions were fine almost all the time, only 10m was not in best shape.
Maybe missed some mults on 10m because of the hard qrm from the radar from SE
direction on sunday. Some nice surprising moves, PJ4 with Nigel G3TXF worked on
4 bands, and 9M6XRO showed up last 10 minutes for a double mult, thanks guys.

Antennas
 80m: 4-SQ
 40m: 3/3el   + 4-SQ
 20m: 6/6/6el + 4el @EU
 15m: 6/6el   + 5el
 10m: 6/6el   + 6el @46m
All controlled by openASC antenna switch controller built by Mike SJ2W.
Had a lack of one antenna on 20m, since we are buildning a new tower for 40/20
which is not finished yet, so the 5 el for 20 is now in that tower with another
5 el, but not connected yet. 


Radios: 2xFT1000MP MKV with SJ2W SO2R controller
Amps:   4CX1500B + ACOM 2000A (Sponsored by Ojojoj Music AB)
Software: N1MM and streaming sound with Live encoder 3.2 for the sound feed.

Thanks for all qsos, will be put on LoTW and eqsl, and if paper needed
direct via SM2LIY.

More antennas up

Posted by sm2wmv on September 18, 2013 Comments Off

This weekend we were a bunch of people helping to get some antennas up. We managed to get the Top 2el on 40m up, the 5/5el stack for 20 and the 3el for 30m up. The top 2el for 40 will be moved up 1.5-2m when the tram wire has been removed, because currently it is in the way. The low 2el for 40m is what is left to put up in the tower and some cables need to be pulled up together with the cabinet which contains a couple of L-matches for the 20 and 40 stack.

We had some issues from a mistake I had made, making the elements all too short since the center segment on the beam was not as wide as intended. It delayed us a 2-3 hours but we managed to get the planned antennas up anyway, even though it was pitch black when the 30m yagi had been mounted and I was climbing down the tower.

We also took down the 5el for 20 that was temporarily sitting in the WARC tower. It was quite windy, I suspect winds of up to 15 m/s in the gusts so it was a bit scary since it’s a pretty weak tower (not that there was any risk of it breaking) so it moves around a lot. When the dog rammed the guy wires running for a stick didn’t make the experience less scary. However it all went according to plan even though the rigging took some time.

Guys helping out this weekend was SM2UVU, SM2LIY, SM2XLL, SM2XJP and Blixten.
