Здравствуйте,
Очень интересная конструкция,  если можно то еще несколько фото с разных ракурсов

Prevod za nas, koji nemamo pojma o Ruskom jeziku:

"Bok!
Vrlo zanimljiv dizajn, ako se može malo više slika iz različitih kutova"
To je molba za tebe Dragan

Oooo zdrastvujte,

Adi, bio u Portogruaro i gledam one kutijice iz raznih rakursa  i kaže mi OPW da je one Ms kutijice radio kod vas, kod Branka. Je li to res tako? Kako god, kutije su ufb precizne i jos onako točkasto zavarene...

Treba nam tankog Ms lima ili još bolje "belog lima" za konzerve (0,2 0,3 0,4 mm), ima to gdje u deželi za kupiti?

ZZ Adamski!

Kutije dobavlja S57C. Ako je veča serija, onda se isplati (5+). Za lim, nemam pojma, gde se to nabavlja (koristim mesing ili alpaku, zavisi, šta mi treba).
I tačno je to, da su kutije UFB i rupe na njima nisu bušene, nego probijane, pa su UFB okrugle i sve paše na knap, ako je crtež pravi. A i cijena je prava. Samo za jednu se ipak ne isplati.

OK Adi, hvala za info,
jasno mi je da se ne isplati to raditi za 1 kom. Vjerovatno se to radi na CNC štanci, ja sam tako radio septum za 23cm na stroju gdje sat rada na CNC štanci košta 100Eura pa mi je jasno koji se problemi (troškovi vremenski pripreme) javljaju.

Kad skupimo vecu kolicinu (cca 20-30 kutija) se javim..

Vrijeme je da se naoruzamo:

Arecibo on 432 MHz Moon Bounce
The Arecibo Observatory Amateur Radio Club will be putting the 1000-foot radio telescope on the air for 432 MHz EME from April 16-18.

It can be heard with a small hand-held yagi pointed at the moon

The scheduled times of operation are:
April 16: 1645 - 1930 UTC
April 17: 1740 - 2020 UTC
April 18: 1840 - 2125 UTC

Callsign: KP4AO

Tx Frequency: 432.045 MHz
Rx Frequency: 432.050 to 432.060+
Tx power: 400 W
Antenna gain: 60 dBi
System noise temp: 120 K (cold sky)
System noise temp: 330 K (when pointed at moon)

KP4AO can be heard with a small hand-held yagi pointed at the moon and a good receiver. A 15 dBi antenna and 100 W will be enough to work us on CW.

Operators at KP4AO will do their best to work as many stations as possible. Each session will start with a brief announcement and CQ in SSB. SSB QSOs may continue for 30 minutes to an hour, if the QSO rate remains high.
The mode will be shifted to CW as soon as it is judged that higher QSO rates would result.

We will listen for calls at frequencies 5-15 kHz higher than our own, and even higher if QRM warrants. Callers who s-p-r-e-a-d o-u-t are more likely to be copied.

If you've already worked us in any mode, please do not call again -- give others a chance.

If we call "CQ QRP", we will listen for stations running 100 W or less to a single yagi. Please do not answer such a CQ if you are running more power or have a larger antenna.

On April 18, if we reach a condition where most calling stations have been worked, and we judge that operating in the digital mode JT65B would produce a higher QSO rate, we will switch to JT65B.

Note that any of these planned operating strategies may be changed as circumstances dictate.

We are extremely fortunate to have been granted access to the world's largest radio telescope for this amateur radio good-will event. We look forward to working as many stations as possible in the alloted time!

Jeste vidjeli kako je majstor naredio sistem...doma 10 GHZ...u svim smjerovima ! Neka prehlada ovđe u mene..? Bah...Prođe valjda za koji dan...? Stigla Qsl-ka iz Sibira ...Nikolaj ima 4x12 elemenata i jednu GI7B oko 300W ....bio čak -19 ! A u to vrijeme vidio se i Kazakhstana UN6PD -21 ...dvije antene i 300W ali mene nije primio...? Paul je napuisao da bude pojačao sistem 4 antena stavi....ovo je primano kada je imao max. GG ! Onaj crni kvadrat je monitor ..TV kamera u antenama pa je screen shot spasi ovako ? Bene...došlo proljeće ..sunce i toplo....more se nešto vani raditi...? Saluti M.
