content: Hey guys,I'm selling these on my website and on eBay.For a limited time, there's a 20% discount available (only on the website). To access it, enter the code "EEVBlog" on the checkout page.If you want the HPO-030-N version, it will be in stock starting with tomorrow or the day after. Personally, I prefer the non-N version and that's the one I recommend as it has a better response in the higher ranges (10 or even 20 dB in some regions). It's still a good choice and it will have better performance than the original also.Unlike with the other options out there, you'll also get a 2-year warranty.Almost posted before dropping the linkhttps://cojotech.com/hpo-030https://cojotech.com/hpo-030-nOn eBay you can find them if you search for HPO-030.Edit:Making youtube videos is not something I excel at, so I hope you'll excuse my clumsiness and my english.Cheers

content: Hey DC1MC,That little plastic cap where it says channel 2 pops off. Then the board gets mounted on the inside, attached to the chassis.I should probably take some photos and make a document with instructions.Edit:I added installation instructions on the product page.Regards

content: I new that, but this is Channel 2, is it actually taking it form where Channel 1 is stopping, is the firmware recognizing it correctly. Anyway,project, and if you actually have some of the devices a short Youtube video, or even a series of pictures will help your sales.Cheers,DC1MC

content: Good point! I suppose I should say channel 2 when it comes to 53181A.Not a bad idea about the videos, although I'm a bit camera shy.Here's a photo I just took, while being gullible and thinking you need instructions on how to install it. Also a demo of the sensitivity.Edit:Oh, and if you're asking if on the 53181A the install is different, it's not. There's an available IDC connector on the mother board, so it has nothing to do with channel 1. The firmware should recognize it properly, as long as you didn't have a 5 GHz or higher (and original) option installed.Edit 2:Added photos of the installed board.

I was lucky and got mine for 100 GBP a couple of years back (but in non-working condition). The OCXO was busted and it wouldn't start because of it.I unplugged the OCXO option and it started working. After that I retrofitted another OCXO on the original board and it's been working fine ever since.
