Duro hf set

Radio Beacon NDB transmitter HF. It has a DDS generator with a step resolution of 1 Hz from 1 to 55 MHz. The final stage (30 W max power) is set to deliver 5 W. It may be set from 3.5 to 15 MHz (may be modified for 30 Mhz operation. The power supply (120 W) works from 100 to 280 Vac and it’s built in. No fans, no noise. The RF stage an oversized heatsink for continuous operation. The radio beacon has a directional beacon to indicate the forward and reflected power. The ID and the Morse code text may be easily reprogrammed, as well as the keying speed and the pause duration just connecting a PC via USB port using a simple code (provided). Very good stability in power and amplitude. For any further information you are welcome to ask !

A vendre est une Japan Radio Corporation NRD 535. Le récepteur est en excellent état et fonctionne parfaitement. Il y a quelques rayures sur le meuble qui se trouvent dans les photos. Le panneau avant montre peu ou pas d'usure. Le cordon d'alimentation sera inclus. La radio sera soigneusement emballée pour l'expédition. Voici un complément d'information du JRC trouvé sur le Web. La Japan Radio Company NRD-535 offre une couverture générale de couverture de 90 à 30000 kHz en mode AM, USB, LSB, CW, RTTY, FAX et FM étroits. Un circuit superheterodyne à triple conversion est utilisé pour offrir une superbe sensibilité et un rejet d'image. Japan Radio a conçu un synthétiseur PLL spécialisé à haute vitesse à 1 Hz pour vous fournir une résolution d'accord de 1 Hz jamais disponible. La résolution de l'écran est de 10 Hz grâce à un affichage magnifique. Une mémoire de balayage non volatile sophistiquée de 200 canaux stocke la fréquence, le mode, la sélection du filtre AGC, ATT et IF. Les canaux peuvent être scannés à un taux défini par l'utilisateur (0,5 à 5 secondes / canal). La réception de balayage peut être réglée de 0,05 à 0,5 secondes / étape. La réputation de Japan Radio pour une stabilité extrême continue avec seulement une dérive de ± 2 PPM (après 1 heure) rendant le NRD-535 le choix inévitable pour les modes exigeants non vocaux tels que le code Morse, RTTY et FAX. Quatre positions de filtre indépendantes sont disponibles. La position WIDE comporte un filtre de 4 kHz (@ -6dB). La position INTERIEURE comporte un filtre de 2 kHz (@ -6dB). Les positions NARRow et AUXiliary ne sont pas remplies. (Une position AUX vide entraîne une bande passante de +12 kHz). Les positions AUXiliary peuvent être utilisées pour monter des filtres optionnels. Tout filtre peut être utilisé avec n'importe quel mode (sauf FM). C'est une fonctionnalité exceptionnelle qui offre une flexibilité pour les auditeurs. Le clavier comporte l'entrée à la fois MHz et kHz. L'entretoise de bruit à double largeur peut être utilisée pour réduire ou éliminer le bruit d'impulsion (comme l'auto-inflammation ou le "pic"). Les autres commandes du panneau avant comprennent: SQUELCH, AF et RF GAIN et TONE. Un bouton AGC permet de sélectionner AGC FAST, SLOW ou OFF. Le bouton DIMMER offre quatre niveaux d'affichage de luminosité. Une horloge intégrée 24 heures sur 24 est fournie. Le TIMER permet l'écoute / l'enregistrement sans surveillance. Le récepteur peut être programmé pour être activé à un moment donné (sur une fréquence, mode, bande passante, etc.) puis éteindre à un moment programmé. Une connexion terminale temporisée est fournie sur le panneau arrière de l'ensemble pour activer un magnétophone. Le NRD-535 contient une interface informatique RS-232 intégrée. Il existe des entrées d'antenne pour fils ou câbles alimentés. La tension d'entrée CA est sélectionnable par l'utilisateur. For sale is a Japan Radio Corporation NRD 535. The receiver is in excellent condition and works perfectly. There are a few scratches on the cabinet which can be seen in the photos. The front panel shows little to no wear. The power cord will be included. The radio will be carefully packed for shipping. Here is more information from JRC found on the web. The Japan Radio Company NRD-535 affords general coverage reception from 90 to 30000 kHz in AM, USB, LSB, CW, RTTY, FAX and narrow FM modes. A triple conversion superheterodyne circuit is employed to provide superb sensitivity and image rejection. Japan Radio has designed a special high-speed 1 Hz step PLL synthesizer to provide you with 1 Hz tuning resolution never before available. Display resolution is 10 Hz via a gorgeous display. A sophisticated 200 channel non-volatile scanning memory stores frequency, mode, AGC, ATT and IF filter selection. Channels can be scanned at a user-defined rate (.5 to 5 seconds/channel). Sweep reception can be adjusted from.05 to.5 seconds/step. Japan Radio's reputation for extreme stability continues with only ± 2 PPM drift (after 1 hour) making the NRD-535 the inevitable choice for the demanding non-voice modes such as Morse code, RTTY and FAX. Four independent filter positions are available. The WIDE position features a 4 kHz (@ -6dB) filter. The INTERmediate position features a 2 kHz (@ -6dB) filter. The NARRow and AUXiliary positions are not filled. (An empty AUX position results in a +12 kHz bandwidth). The AUXiliary positions can be used to mount optional filters. Any filter may be used with any mode (except FM). This is an exceptional feature that provides listener flexibility. The keypad features both MHz and kHz input. The dual-width noise blanker can be used to reduce or eliminate pulse noise (like auto ignition or the "woodpecker"). Other front panel controls include: SQUELCH, AF and RF GAIN and TONE. An AGC button permits the selection of AGC FAST, SLOW or OFF. The DIMMER button offers four brightness display levels. A built-in 24 hour clock timer is provided. The TIMER permits unattended listening/recording. The receiver can be programmed to be turned on at a particular time (on a set frequency, mode, bandwidth, etc.) and then turn off at a programmed time. A timer-out terminal connection is provided on the back panel of the set to activate a tape recorder. The NRD-535 contains a built-in RS-232 computer interface. There are antenna inputs for wire or coax fed. The AC input voltage is user selectable.

  The MFJ-259B SWR analyzer features a built-in 10 digit high-contrast LCD frequency counter. Reading your antennas SWR and finding its resonance has never been easier. All you do is connect your antenna, set your SWR analyzer to the frequency you want and read your SWR. MFJ-259B gives you a complete pictures of your antenna's performance. You can read antenna SWR and Complex Impedance 1.8 to 170 MHz. Read Complex Impedance as series resistance and reactance (R+jX) or as magnitude (Z) and phase (degrees). You can determine velocity factor, coax cable loss in dB, length of coax and distance to a short or open in feet. You can read SWR, return loss and reflection coefficient at any frequency simultaneously at a single glance. Also read inductance in UH and capacitance in pF at RF frequencies. The large easy-to-read two line LCD screen and side-by-side meters clearly display your information. The built-in frequency counter, Ni-Cad charger circuit, battery saver, low battery warning and smooth re-duction drive tuning and much more. The MFJ-259B is easy to use!
