On the table are : transceiver CB Avanti Alpha + EA35 + Zetagi MM27 and a DC switch power supply.
This is the RF shock made from the coaxial cable at ~L/4 = 2.6m, diameter of the coil is 3cm.
And that is a beautiful CB antenna Sirio Blue Line 3000, fixed outside the window at 40cm from the building wall, 7.2m high from the ground.
The SWR is 1:1 and the antenna take the power without any problems, so that cloud be a solution when you don't have the space to mount other base CB antenna, or you must improvise something quickly for an emergency situation.
An other good CB antenna is the Sirio Super S9, and in the test it was working well tuned only with the transmatch, no shock coil.

Incarcarea acumulatorilor NiCd si NiMH
Bateriile obisnuite chiar si cele alcaline sunt depasite la unele aplicatii de acumulatorii NiMH al caror pret de cost a scazut foarte mult in ultima vreme (sub 10$/4buc), iar incarcatorul necesar se livreaza la pachet si el ... tot ce-i mai trebuie este un releu de timp electromecanic sau electronic pt. a programa durata incarcarii data in tabel.

Baluns for CB antenna
O antena filara tip LW este destul de greu de acordat fara un balun bun. In imagini se pot vedea doua solutii tehnice pe care le-am experimentat cu succes: un "trifilar" bobinat pe un tor de ferita cu diametru mare, celalant un "cincifilar" bobinat in aer.

Antena CB a lui 233YO193
SIERRA ALFA International DX Group
Doua cluburi de radio CB unul italian SA si altul romanesc YO s-au infratit, iar doi oameni au devenit prieteni buni : 1SA002 - Mark si 233YO010 - Silviu.
Toti cei interesati de activitatile colegilor din Italia pot vizita site-ul lor pe internet la adresa : www.sierraalfaregioni.it

De vreo doua zile ma lupt sa scap de propagarea asta de vara, si-n disperare de cauza am pus cea mai mica antena home made pe care o am, un wipe pe fibra de sticla lung de 5 ft. pus vertical in geam, dar in loc sa scap de DX-uri azi am luat 5/8 de la 1SA002 - Mark, 25Km from Milano, Italy, 14:30cfr/.540usb, Icom 738, vertical 5/8 & 60w ; 1AT389 - Paulo, NW Italy ; si-am mai lucrat un YO9 "bau bau" :-) din Nuremberg pe 20FM.

"Cornel Tirgoviste" din Grecia
Cornel din Tirgoviste era prin Atena in Grecia si lucra cu o statie Avanti Kappa.
A vorbit azi cu multi colegi din tara care au fost pe "faza" (Cluj, Timisoara, Izvoru Rece) eu n-am reusit decit un RX frumos.

35AT015 - Mr. Roland, Vienna, Austria
Un QSL de toata frumusetea primit prin posta din Austria zilele trecute.
Propagarea pe distante scurte a fost buna atunci si ne-am auzit apoape ca la telefon, am avut si noroc cu statia Avanti Grande care lucreaza pe frecventele "cu zero in coada".

Storm Defender inside view
Ce sa mai spun ... un lucru bine facut, ecranaje unde trebuie, filtru antiparaziti cu ferita pe tensiunea de alimentare, tehnologie micro SMD etc.
Am reglat numai un pic la modulatia FM, la AM nu e nevoie, si vad ca este si-un jumper + fir alb in zona PLL, deci mai mult ca sigur se poate debloca si in frecventa.

Mai are rost oare sa comentez ceva ? :-)
Eu unul depun armele in fata acestui arsenal si ma las de radio CB... serios ! Practic n-am nici o sansa sa fac asa ceva pe plaiurile mioritice.
73's ! QRT !

LW antenna for CB
La nevoie cea mai buna ferita pt un balun de calitate este ... aerul ! :-)
"Bobina" are 5sp. trifilar de 0,75mmp folosit in electrice si un diametru de cca. 3".
Impreuna cu transmatch-ul de la Zetagi acordeaza perfect un LW clasic de 5.5m.
