Recommendations for use and support

1 - Do not connect the RSPdx directly to the same antenna as your transmitter, or to a transmitting antenna, nor transmit and transmit signals near the RSP, as this may result in irreversible and unsupported damage. by the guarantee.

2 - The RSPdx, like any SDR receiver, is sensitive to electrostatic discharge that can damage the receiver if it is not protected or used properly. It is recommended to disconnect the antenna in stormy weather and to ground the antenna. Finally before reconnecting the coaxial cable after a thunderstorm, it is imperative to unload it (braid and core) by grounding it.

In these 2 cases of loss of reception and RF damages, the guarantee can not be applied and the equipment will not be repaired, exchanged or refunded. The signs of RF damage are characterized by signs of hot on or around components near the signal input, a burning smell is also an indication of RF damage.

Je ne trouve nulle part la configuration PC minimale à avoir pour pouvoir utiliser SDRplay et son logiciel SDRUno de façon optimale. Avez-vous une indication à ce sujet ?


La configuration minimale recommandée pour PC de bureau ou portable avec le logiciel SDRuno est un microprocesseur (CPU) de type Intel Core i3 ou équivalent et 4Go de mémoire RAM.

Pour une utilisation au maximum des performances, un CPU Core i5 avec 8Go est recommandé.

Le logiciel pourra fonctionner sur des configurations inférieurs à celles recommandées, mais dans ce cas la bande passante à l'écran ne pourra pas aller jusqu'à 10Mhz affichée. Il faudra réduire la largeur du spectre jusqu'à ce que le PC retrouve des ressources.

SDRUno indique le pourcentage d'utilisation du CPU et de la mémoire du PC pour vérifier en temps réel les ressources PC utilisées.

Ma question concerne le sdrplay RSP1A et RSPdx, je fonctionne sous linux et je voulais savoir si la sélection d'antenne et des filtres fonctionne sous gqrx ou cubic sdr ?


Avec le logiciel CubicSDR, toutes les versions RSP sont supportées (RSP1, RSP1A, RSP2, RSP2PRO, RSPdx et RSPduo), il faut pour cela utiliser l'API 3.07 et le nouveau SoapySDRPlay. Un webinar (en anglais) est disponible sur Youtube :

Pour GQRX, il ne semble supporter à ce jour que les versions RSP1, RSP1A et RSP2.

Question about the product

SDR large bande et optimisé HF !
De bonnes performances sur toute la plage de fréquences annoncée.

De plus :
* Pour la HF, les filtres de présélection et le filtre notch SW améliorent les performances en évitant la saturation de l'ADC liée aux stations broadcast.
* Le bias-T sur le port SMA (B), très pratique, me permet d'alimenter une antenne loop active type MLA-30.

Pour la livraison et le suivi, parfait dans l'ensemble.
apres le RSP1A en fonction depuis deux ans et en etant tres satisfait il fallait evoluer et voir le nouveau modele!! et je regrette pas mon achat la nouvelle mouture tient la route!! la rsp1a est bien mais le rspdx est mieux!! reçu par la poste sans probleme comme toutes mes commandes passées aupres de passion radio!! merci à eux pour leur serieux!! jm
