Very fun 6m run tonight

After putting up the yagi and not hearing a single beacon for few days I was becoming desperate, so I finished my HRD + Ipsound setup and rigged the TS-570 for remote control. Now I sit @ work with the 6m band humming in my ear.

I can’t use the remote control to transmit, I think all my co-workers would send me to some nut house if I would start DX’ing in the middle of the office..

So around 16:00 GMT I heard a weak beacon, so I hurried home and started skimming the frequency, nothing.. just went. So around 20:39 TF1SIX was spotted and I started calling CQ … without hearing any other beacons. I got a solid response from MM5AJW. So as the night progressed I ended up with around 50 contacts, around 15 to the east coast of USA.

Now I got a very interesting mail I have to read, urging me to try EME on 6m !!

6meters – my new favorite ;)

My brother, Gudmi TF3SG, sent a email to the local amateur group that he heard a beacon on the 6m band. I have not been very interested in this band before, but decided to jump to 6m on the TS-570. My antenna is a short G5RV dipole strung from a tree to a scaffolding. I started scanning the band and heard a faint beacon on 50.093, I tuned slowly up band and fond a very strong signal, S9+. My first thought was that this had to be a local station close by, but it was David, MM5DWW. I decided just for fun to try the auto tuner in the Kenwood, thinking even if I could get around 5W into the antenna I should make it work. To my surprise, the SWR was low, 1,5 so I just went for full power and responded to the CQ. I took 3 QSO’s that night (1 june at 23:44 GMT), then my wife yelled as she was trying to get to sleep.

Now I must be ready for any opening and started building a yagi for the 6M band.

So here is some pictures of the ruggedly built 6m yagi, I went to google for design ideas and after spending to many hours reading and looking at different designs, I had transferred a yagi I found in the ARRL handbook over to metric measurements, but I decided in the end to use a optimized design from a German webpage – but when put in EzNEC, I could not make it work. Then I found out that the diameter from the ARRL is quite big, 20mm – to 16mm that is a total overkill for a 3m span, but I had to change the scale of the antenna. So – I’m going to test the antenna – works perfectly in EzNEC – but let’s see how it fairs in real world.

I also should state that I have a special connection to the 6M band, my father TF3T – formerly TF3SG was the first amateur in Iceland to get the permit on 6M and make the first contact, I think he was one of the first in EU actually, need to ask him about that. But somehow I have always been uninterested in the 6M band – that changed after my first QSO’s.

WordPress problems…

This is a new version of the site…

after having very strange stalling issues with WordPress, when loading the page, it would just wait 10-15s before anything would be transferred out of the server. Tried disabling all addons, etc.. In the end, I just downloaded newest version of WP, theme and some plugins.. seems to work now. Manually transferred over – so I would not carry over some shit from the previous install…

Fyrstu loftnetspælingarnar!

Jæja, þá lánaði Pabbi mér TS-570S, fínasta stöð

Þá er málið, hvernig skal maður koma sér í loftið. Ég bý á jarðhæð í blokk í Grafarholtinu, svo það er nokkuð snúið að koma sér í loftið.

Ég ákvað að byrja að koma mér í loftið í skjóli næturs, þ.e. setja upp loftnet þegar rökkva tekur og krakkarnir hættir að leika sér í “garðinum”. (það er allt hverfið þarna).

Hér má sjá mjög aumingjalegan vertical, með hustler 20m spólu sem TF3T lánaði mér.. smá radíalar og stög.

Fyrsta kvöldið heyrði ég bara ekkert nema surg og læti, rétt náði QSO við TF3SG á 20m. Nú í kvöld prófaði ég að skipta út switch-mode PSU sem ég nota yfirleitt til að hlaða stór LiPO batterí í RC sportinu, setti hefðbundið supply sem notast við spennubreyti – og vola! ekkert suð, en aðeins 50W possible! Nú vantar mig almennilegt supply

Ég er nú byrjaður á næsta projecti

það verður Inverted-V, verður sett upp með 5m mastri …í skjóli næturs ;P

ég byrjaði að búa til 1:1 balún…

13 vöf af 14awg vír, …hvernig lýst ykkur á ?

Komið í kassa.. ég náttúrlega tóks að klúðra þessu, stytti vírana of mikið…

Þá koma nokkrar spurningar.

1. Er svona rúst-frítt / ryðfrítt efni eins og ég notaði í úttökin í lagi ?

2. er í lagi að lóða svona víra saman ? ekkert issue með leiðni?

3. hvernig lýst ykkur á ? ;P meikar þetta sense til að hafa í toppinum á inv. V?
