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.
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.
The receive amplifier on mine died in close proximity to a power amp that malfunctioned. It wasn't even activated at the time only the HackRF. It's not attenuating but it basically has little to no gain anymore. They are quite fragile.
Hello sir, thank you for your videos. I have a question about the Clifford edition of HackRF: When I bought my HackRF, there were two versions: the Chinese and the American. Supposedly the Chinese version was not blocked in the bands reserved for cell phones. I would like to know if the Clifford edition has this lock.
I’m not aware of any blocked cell phone bands in any of the HackRF variants. The only difference between the Chinese and the “American” version is who made it. The designs are open source and identical.
@@bukucsjozsef9630 Hello I have TX power issues. On rx reception is good and if I turn the AMP on signal increases. However if I transmit I can hardly transmit… and if I turn AMP ON it increases the power signal. Given this facts, do you think the AMPs are fine? Arent the amps the new TRF37B73 I think there could be a problem on the previous tx stage. But I am lost here 😓
@@Radiogenes Before you fix it, check if this problem exists on another computer. Especially if you use SDRangel software, other connected USB devices or HUB caused a similar error for me. Of course, I also suspected (wrong) the hackrf module. But not was.
hi! really interesting. I have experience replacing the MGA81563 on the older board, however I also have the new one and I experience power issues. What is the component to change in the new board? thanks!
I think mine is weird because iamp works on RX, but my unit just transmits very low power. However it does improve its power with the amp ON, so maybe i have another tx stage broken? The previous one?
@@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.
Hey buddy, great video. Is there a way to tell if I have (software wise) this version? I might have to read through the listing properly.. 😅 I bought mine about 3 weeks ago from the same source on AliExpress and didn't realise I might be lucky enough to not accidentally fry my unit as a newbie into this whole thing.. 😅 Would be nice to know if mine is better protected. Thanks in advance and keep up the great work! Edit: Just double checked listing and it says HackRF One:R9 and Portapack H2:R4
I don’t think there is a way to tell from the software but unless the listing specifically says that it’s the Clifford version, I don’t think you’ve got one.
@@sn0ren Yeah, I think you're right unfortunately.. 😢 Thanks for the quick reply though! I'm thinking of trying the LNA provided in bundle pack 4 but worried I read somewhere it could be a little sketchy, combined with your warning video here, I'm really second-guessing the idea..
If I order the new Clifford board I assume it is compatible with existing portapack? My amp is shot but want to make sure I can just swap out the hackRF board with current portapsck/case etc. I’m guessing so just wanted clarification.
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.
@@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.
Clifford’s version is based on the 2019 version. As far as I know the changes in versions since have been mostly about using chips that are available for purchase.
Should I use the Clifford addition in my portapack or use the original? I have the original Hack rf but may use it standalone and buy cliffs with this error happening
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.
@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.
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?
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.
Is the version of hardware you now use compatable and upgradeable with the latest mayhem firmware ? I understand some of the portapacks out there are not compatible.
CZcamsr Are you Clifford Heath? The same machine is on sale at different prices, can I just buy this? Thanks to you, I found this amazing and interesting equipment.
