Cu antena asta pe care o am acum nu credeam ca ajung in Rusia ... si totusi uite ca se aude pina acolo, iar acum am si-un foarte frumos QSL primit prin posta.

Placa de ecou pt. Storm Defender 2

Este mica si e lucrata in tehnologia SMD, iar montajul este relativ usor caci mai nou conectorul este lipit pe placa de baza, reglajul este mai delicat si cere timp plus atentie si o ureche muzicala... dar merita.

Propagarea e foarte buna in 11/10m si se pare ca mai am un elev bun la DX pe linga 233YO333... 233YO150/YO2MOO - Petre, care ieri a facut  lucrind din mobil inca 5 entitati radio noi din care 2 japonezi, iar  cind a auzit ca-i radpunde japonezu' cu "PetreSan" :-) s-a pierdut de bucurie.

On line forecast for CB11m band

Colegul nostru 233YO150 - Petre, ne-a trimis un link foarte util pentru predictia propagarii in 11m... TNX !!

http://www.voacap.com/11coverage.html

Sursa tensiune 5...20V/2...10A

Este o schema clasica, pe vremuri era scumpa caci erau greu de gasit componentele necesare, dar era "TipTop" :-), astazi poate parea usor depasita moral de noile integrate specilaziate, oricum fata de alte prostii publicate pe net ... asta functioneaza la mine de vreo 25 de ani.
Integratul folosit este un bM324 (amplificator operational quadruplu), cu A1 se face referinta de tensiune dictata de dioda zenner (6,2V), A2 comparator de eroare (pe intrarea neinversoare primeste referinta de tensiune, iar pe intrarea inversoare este adusa o fractine din tensiunea de iesire) iesirea lui comanda elementul de putere 2x2N3055. Protectia la curent depasit / scurt pe iesire se face cu A3, "senzorul" de curent este o rezistenta de valoare mica 0,5 ohmi pe care apare o cadere de tensiune comparata cu referinta de 0,6V data de dioda 1N4148, iesirea lui A3 poate pune la masa tensiunea de comanda de pe baza in caz de scurt, iar semnalizarea se face cu A4 a carui iesire comanda un LED de pe panoul frontal.
Partea de trafo si redresare nu figureaza in schema ... am pus o filtrare buna cu cel putin 4700uF, o punte de 3A, si-am deparazitat diodele cu 10...22nF.
In ultima vreme de cind cu RRU / ISU am setat 14,4Vdc out si incarc non stop cu ea o baterie de 12V/5A din care alimentez o statie QRP pe CB11m, si incarc in stand by doua portabile... una de 11m (Team MiniCom) alta de 2m (Motorola GP300).
