The HackRF Portapack is a handheld SDR transceiver, capable of manipulating radio waves, decoding digital signals and giving you an insight into the invisible electromagnetic world around us. It does however suffer from a huge flaw, that can render it apparently completely unable of receiving anything. Also learn how to use the gains settings LNA, VGA and Amp on your HackRF Portapack.
The Clifford Heath edition of the HackRF Portapack, which is shown in this video, has been provided to me for free by OpenSourceSDR Lab. You can buy the same one here: www.aliexpress.com/item/10050...

So, the R9 is a dud, the Clifford HackRF edition Portapack that I purchased is marked R9, nothing to show it has the Clifford mod ? it has no sound, it is not recognized be RTL Sharp or Console, I know this is a common issue, guessing that its related to the need to come up with the R10 based on R8. Hacker Doc. (hardware revision) One r9 MAX2837 was replaced by MAX2839. Si5351C was replaced by Si5351A with additional clock distribution. A series diode was added to the antenna port power supply. Manufacturing year: 2023 HackRF One r10 This revision is based on r8, reverting most of the changes made in r9. A series diode was added to the antenna port power supply. Manufacturing year: 2024

Thank you for making this for folks. I know most people delving into radio, having don't have a background in ham radio, so they're not aware of the pitfalls of using the internal amp and whatnot.

yes, but the clifford addition comes with it's own downsides, greatscott tested it and showed the results on their site (but didn't call it clifford by name). i've independently tested and got the same results as them, there is a 15-20db loss on the upper and higher bands, and a 10db across the entire range. it's pretty significant, but does reduce chances of blowing your amp.

@sn0ren 4 ай бұрын

Yeah I’ve seen that. Clifford claims that testing was done on a defective device. I don’t know enough about it to come to any conclusion about that. Personally my Clifford device is clearly more sensitive than my other r9 board, but that might be other variances of manufacturing or defects, and also I haven’t used it for anything above 1GHz. Both cards are from cheap Chinese manufacturers. I don’t have any GSG sold device to compare with. And if you just need receive and not at high GHz ranges I’ve found RTL-SDR blog v4 to be more sensitive than either HackRF device.

@@sn0renit can actually put more strain on the sma connectors if the coax cables you use are thicker and not so flexible. Just be aware of that. If it's just for rubber duck changes and thin coax it's not really a problem. I use adapters often from sma to bnc they work ok except they tend to unscrew when you try to remove the bnc connector.

Radios are heavily amplifying really weak amounts of electricity pulled out from thin air. They are delicate sensitive devices and it’s expensive to make them able of picking out the smallest hint of a signal and simultaneously withstand rough handling. We are lucky we get to pay with these cheaper devices at least, even if they sometimes break.

@mr.s1961 3 ай бұрын

@@sn0ren That's why we should all get a professional-level SDR like LimeSDR or likes and never worry about blowing amps.. a LimeSDR will blow a RTLSDR or other device connected to it before it blows itself, and its basically the same pricerange of a HackRF thru Ossman website. But you also get full duplex, 2 tx and 2 rx (as you know HackRF is half with 1 rx/tx). Someone should create a portapack for that and that will be real mayhem. Poor understanding of hardware via creator/manufacturing is no excuse lol.

How to make it more sensitive on receiving? Compared to a RTL-SDR V3 i have, the hack rf is way less sensitive. Is there anything we can do to increase it?

@sn0ren 4 ай бұрын

If you just need a receiver rtl-sdr is better. But HackRF can also transmit and has a much wider range and can be used portable with the Portapack. Any choice is a compromise in some way. The little external 20dB LNA might help in some cases in increasing sensitivity.

Hi, How can you tell if you have the clifford heath version of the HackRF? is there a way to identify the true version from clones?

@_specialneeds 2 ай бұрын

Good question.

@sn0ren 2 ай бұрын

Look at the chip near the USB port on the HackRF. If it has 6 pins it's the normal design. If it has 8 pins it's a clifford design. Every board sold from aliexpress, wether being clifford or regular version is a "clone". If you want an "original" HackRF you need to buy it directly from Great Scott Gadgets, Michael Ossmans company. The term original and clone isn't as descriptive though, since it's an open source hardware design, so the boards you can get off aliexpress are identical to those sold by GSG, they are just manufactured by someone else. The only difference, if any, can be in quality control.

@KB1UIF 2 ай бұрын

@sn0ren Thank you for the reply. Yes, I have an original GSG HackRF I just bought another HackRF and Portapack by following the link you provided. I wanted to check it's based on the clifford heath design as some have painted logos and some use stickers for the logo. It's not easy to confirm what I was sent. But at least I now have something to check. I was going to look for a diode package or packages at the antenna input as this was something mentioned in the video. Edit : I just checked this one and it has an 8pin chip near the USB connector. Thanks.
