CONSIGLI D'USO
Per un corretto uso dell'amplificatore V-ULA 50 si consiglia di posizio-
narlo in modo che sia assicurato un sufficiente flusso di aria al radiatore di
calore, utilizzare cavi di alimentazione il più corti possibile e comunque non più
lunghi di 3 m., possibilmente collegati direttamente alla batteria e di sezione
non inferiore a 2,5 mm².
Il cavo di discesa a 50 Ω, deve essere di buona qualità, adeguato alla frequenza
ed alla potenza di lavoro e di lunghezza minima necessaria in quanto introduce
una sensibile attenuazione in trasmissione con perdita di potenza e soprattutto in
ricezione peggiorando il rapporto segnale-rumore, utilizzare un'antenna che
accetti largamente la potenza dellamplificatore, e che abbia ROS non superiore
a 1.5 alla massima potenza, i connettori devono essere di alta qualità in teflon.
Il collegamento tra RTX e Lineare deve essere effettuato con cavo a 50 Ω,
lungo 70 cm.
Non rimanere in trasmissione per lungo tempo senza intervalli ragionevoli per
permettere il raffreddamento dei transistors. In caso di utilizzo in stazione base
si consiglia l'utilizzo di una batteria con caricabatteria in tampone .
Laccensione del LED indica lintervento della protezione per livello eccessi-
vo di onde stazionarie (ROS), per il ripristino della funzionalità del lineare

Suggestion of use
For the correct use of the AMPLIFIER V-ULA 50 it is advised to posi-
tion it in such a way to assure a sufficient flow of air to the heat-radiator. Use
as short as possible feeding cables, however not longer than 3 meters, directly
connected to the battery with a section of 2,5 mm² minimum
The descend cable 50 Ωhas to be of good quality, suitable to the fre-
quency and to the power of job and with the minimum required length as it in-
troduces a sensitive attenuation in transmission with loss of power and espe-
cially in receipt worsening the relationship signal-noise.
Use a spar largely accepting the power of AMPLIFIER and having
SWR not exceeding 1.5 at the max power. Use high quality Teflon connectors.
The connection between RTX and AMPLIFIER has to be effected with
50 Ωcable 70 cm. long.
Do not remain in transmission for long time without reasonable inter-
vals to allow the cooling of the transistors. In case of use in basic station it is
recommended the use of a battery with battery charge in buffer.
The lighting of led indicates the intervention of protection for exces-
sive level of SWR, to restore the functionality of the AMPLIFIER switch
Machen sie keine zu langen Durchgänge, um den Verstärker nicht zu
erhitzen ! Bei max. Leistung Stationärbeitreb achten Sie bitte darauf, daß ein
stabilisiertes Netzteil mit ausreichender Stromstärke benutzt wird!
LED () zeigt ein schlechtes SWR an, TX ist sofort zu unterbrechen.
Position: SIMPLEX
Der Verstärker erkennt und arbeitet automatisch in dem von Ihnen
gewählten Frequenzbereich.
Position: DUPLEX
der Verstärker wechselt automatisch in das von Ihnen gewünschte Band
und erkennt den Empfänger automatisch.
Die grüne LED zeigt an, das Empfangssignal ebenfalls Verstärkt wird.
Nach dem Kauf wird eine Garantie von 24 Monaten gewährt. Auf
Endstufe und andere Halbleiter wird keine Garantie gewährt !!!
Achten Sie darauf, dass der Verstärker nur von Befugten in Betrieb
genommen werden darf. Bei Nichtbeachtung droht Geld-oder Haftstrafe.

CONSEJOS PARA SU USO
Para un correcto uso del amplificador V-ULA 50, es aconsejable situarlo
de manera que quede asegurado un suficiente flujo de aire hacia el radiador de
calor, utilizar asimismo un cable de alimentación lo más corto posible, en
ningún caso mayor de 3 m., y a ser posible, conectado directamente a la batería,
con una sección no inferior a 1,5 mm².
La bajada de antena de 50 Ω, debe ser de buena calidad, adecuado a la
frecuencia y potencia de trabajo. Dicho cable, deberá tener el mínimo largo
necesario para evitar la sensible atenuación y la consiguiente pérdida de poten-
cia, y sobre todo en recepción al empeorar la relación señal-ruido. Utilizar
también una antena que permita ampliamente la potencia del amplificador, con
una R.O.E. no superior a 1/1,5 en la máxima potencia. Los conectores deberán
ser de alta calidad, a ser posible en teflón.
En enlace entre el transceptor y el lineal, debe ser efectuado con cable de
50 Ω, de una medida de 70 cm.
No permanecer en transmisión mucho tiempo sin un espacio razonable
que permita el enfriamiento de los transistores. En caso de uso en estación base
se aconseja usar una batería con carga permanente.
En encendido del LED , indica el funcionamiento de protección por un
excesivo nivel de R.O.E.. Para reiniciar la operación y el funcionamiento del
amplificador, apagar y encender el interruptor , después de haber eliminado

OFF and ON after eliminating the reason calling for protection.
V-ULA 50 amplifier, is a 2 m. 70 cm. full duplex dual band amplifier,
provided with two distinct circuits compost of amplifier and preamplifier cou-
pled by means of proper round duplexers.
Position SIMPLEX.
The amplifier automatically recognized the used band and set itself on
it either in reception and in transmission, so it acts as regular Speak-listen am-
plifier. When transmitting the band is evidenced by the commute green to red of
one of the two apposite leds.
Position DUPLEX.
The amplifier automatically sets itself in transmission in the band re-
quired by ricetranceiver and in reception in the opposite band, so that working
in full duplex; This status is evidence by the colour of the two leds and 
red TX and green RX.
The green light indicate the operating status of the antenna preamplifier.
24 months warranty from date of receipt.
Please note that the use of LINEAR AMPLIFIER is ruled by specific
laws, that are to be known by the user, anyway the manufacturer declines any
responsibility coming from an uncorrected use.
Any warranty is cancelled if the above instructions are not ob-
served. Final transistor and esthetical parts are not included in the war-
ranty.

Conseils dinstallation :
Pour fonctionner correctement, votre amplificateur V-ULA 50 doit
impérativement être installé dans un endroit sec et aéré de manière à ce que la
chaleur dégagée par le radiateur soit librement évacuée. Les fils dalimentation
doivent avoir un diamètre dau-moins 2,5 mm² et être le plus court possible (ne
pas excéder 3 m).
Les câbles coaxiaux (50 ohms) utilisés doivent être de bonne qualité et
capable de véhiculer la puissance délivrée par le V-ULA 50. Leur longueur ne
doit par être excessive afin de ne pas induire datténuations tant dans la puis-
sance émise que dans les signaux reçus. Des connecteurs type Téflon sont
recommandés.
Le ROS ne doit pas excédé 1:1,5 lorsque lamplificateur
délivre sa puissance maximale.
La longueur de câble préconisée entre lémetteur-récepteur et lamplifi-
cateur est d'environ 70 cm.
Pour une utilisation en fixe, il est vivement recommandé dutiliser une
alimentation très performante et capable de délivrer lampérage nécessaire pour
un fonctionnement correct du V-ULA 50.
Les périodes démission ne doivent pas être trop prolongée afin que les
transistors de puissance refroidissent normalement.
En cas de ROS anormalement élevé, la protection du V-ULA 50 
entrera en action. Lamplificateur doit être éteint puis remis sous tension 
pour la déverrouiller.
Le V-ULA 50 est un amplificateur 2 m. et 70 cm. Il sagit dun amplifi-
cateur double bande «full duplex», construit avec deux circuits distincts com-
posés dun amplificateur et dun préamplificateur de réception couplés par un
système de duplexeurs.
Position SIMPLEX
Lamplificateur reconnaît automatiquement la bande utilisée et bascule
directement en émission ou en réception selon si vous parlez ou écoutez.
Quand vous transmettez une Led rouge ou verte sallume correspondant à la
bande utilisée.
Position DUPLEX
Lamplificateur bascule automatiquement en émission sur la bande
utilisée et en réception sur la bande opposée pour travailler en «full duplex».
Cette situation est mise en évidence par la couleur des Led et (rouge pour
TX ou verte pour RX).
Lorsque la Led verte est allumée cela indique le fonctionnement du
préamplificateur dantenne
La période de garanti est de 24 mois, les transistors de puissance ne sont
pas couverts par celle-ci.

SICHERHEITS-HINWEISE
Für den Betrieb des Verstärkers V-ULA 50 sollte ein gut durchlüfteter
Platz zur Montage gesucht werden. Möglichst nicht in der Nähe von Heizungs-
ausgängen betreiben! Für die Stromzuführung nur ein Kabel mit 2,5 mm
Durchmesser (Plus und Minus) benutzen, das nicht länger als 3 m ist.
Das verwendete Kabel (50 OHM) sollte möglichst geringe Dämpfung
haben, um TX + RX nicht zu verringern!
Benutzen Sie nur Verbindungsstecker mit Teflon-Isolator. Die Stecker
sollten für die Frequenz des Verstärkers möglichst verlustarm gewählt werden.
Achten Sie darauf, dass das SWR unter 1:1,5 ist. Notfalls justieren Sie Ihre
verwendete Antenne, um die maximale Leistung abstrahlen zu können.
