I am interested in the Hackrf with portapack h4c, however I would like to ask a question since the device suffer from the following: The HackRF One, while versatile for software-defined radio applications, has a known issue where the RF amplifier can be damaged by excessive power, especially when transmitting at lower frequencies. Specifically, a slight arc (presumably from an antenna) can lead to overheating and potentially burn out the amplifier chip. This is more likely to occur when transmitting below 100 MHz with the amplifier enabled. So in this model is it modified to against the above.

Thank you for your question and for your interest in the HackRF with Portapack H4C. You're absolutely right, the original HackRF One can indeed suffer from RF amplifier damage, especially when transmitting below 100 MHz with the amplifier enabled. This is typically caused by voltage spikes or slight arcs at the antenna, which can lead to overheating or permanent damage to the front-end components. However, the Clifford Heath New Generation HackRF (H4M R10C) model has addressed and resolved this issue. It features improved protection circuitry and design enhancements specifically intended to prevent RF amplifier damage during low-frequency transmissions. You can find and purchase this updated and safer version directly from us here: https://www.sdrstore.eu/software-defined-radio/instruments/hackrf/clifford-heath-new-generation-hackrf-portapack-h4m-r10c/ Let us know if you have any further questions!

Is an actual HackrfOne board included in this?

Yes, the package includes the HackRF board, the PortaPack, and any applicable accessories, depending on the specific bundle purchased.

Can this decode pocsag out the box or need extra setup?

Yes, the Mayhem flashed PortaPack H4M decodes POCSAG out of the box. Just: 1.Insert the FAT32 microSD card 2.From the Mayhem menu select the POCSAG app 3.Tune to your pager frequency in NFM, set RF/audio gain 4.Pick the correct baud (512/1200/2400) and polarity No extra hardware or downloads required.

What's the range like on stock antenna?

The range with the stock antenna typically covers a broad spectrum from 1 MHz to 6 GHz. For best performance, it’s recommended to use a higher-gain antenna tailored to specific frequencies or bands you're interested in.

Très satisfait de cet achat, délai de livraison standard, effectuée par l'entreprise de distribution nationale et non une entreprise quelconque.

Petite question :
D'après mes recherches, un chargeur 5.0v 2.0A est recommandé, peut-on utiliser un chargeur plus puissant comme 5.0v 3.0A ou rapide 5.0-20.0v 6.2-3.25A sans risque pour l'appareil ?

Cordialement.

Advantages

Très bon rapport qualité/prix par rapport à d'autres sites marchands.
Service client de qualité !

Disadvantages

Une visse un peu abîmée, manque de serrage du côté de la visse abîmée (détails).
Un manuel d'utilisation serait bienvenu pour les débutants comme moi !

Bonjour, Merci beaucoup pour votre retour détaillé et positif ! Nous sommes ravis que vous soyez satisfait de votre achat et de notre service client. Nous prenons note de vos suggestions concernant la vis et le manuel d’utilisation, et nous allons les étudier pour améliorer l’expérience de nos clients débutants. Concernant votre question sur le chargeur : nous recommandons d’utiliser uniquement le câble fourni avec l’appareil. Celui-ci permet déjà une charge rapide, et nous ne pouvons pas garantir la sécurité ou la compatibilité avec d’autres chargeurs, même plus puissants ou rapides. Merci encore pour votre confiance et vos remarques précieuses ! Cordialement, The SDRstore Team

Love messing around with this thing. It’s kinda addicting honestly. The build feels solid, screen’s nice, and it picks up a ton. Took a star off for the learning curve but once you figure it out it’s a beast.

Advantages

Preflashed with Mayhem was super helpful, didn’t have to mess around with anything. It just booted up and was ready. The UI is pretty slick too. Definitely a step up from the older ones I’ve used.

I am currently experimenting with the ads-b function and I can say it works really well. I tested it against flightradar24 and I was picking up planes from 400+ km away which was pretty insane for only a small antenna. I haven't yet tested other functions but will do. I can definitely say its a good product.

Advantages

Fast delivery and very good customer support.

Disadvantages

No
