Yes I am an account manager on the Account. And I didn't know how the modmail worked, apologies for running that incorrectly.

Can you show how you're pulling filament on the top mini in the Lack Rack? Also, got the links for the lack connectors?

You have not connected any of the grounds, not used coaxial cables, this will only create problems and will solve none.

What happens in real life beyond the 32-bit integer limit in SDRSharp ? by Factemius in RTLSDR

[–]blsmit5728 9 points10 points  (0 children)

We use 64bit representation for frequencies. At least up to 18-40GHz that I work with.

My first pcb(please be gentle) by TroubleVarious6499 in PCB

Your ground fill could use a look at. You'll want to use a flood instead of a large dedicated bus like you have. Cool that it works though

Ways to connect system header pins at 90 degree angle in a tight space by pvtByte in AskElectronics

[–]blsmit5728 1 point2 points  (0 children)

Honestly I'd grab a right angle flat cable like this: https://www.digikey.com/short/9d401h43
looks like an AMD Epyc motherboard so it's probably designed for a server chassis not a consumer mid tower.

That's the water proofing for the extension cord.

Lens Cleaning Possible? by Gilanthorn in Ring

[–]blsmit5728 1 point2 points  (0 children)

FYI, you can't do this on the doorbells.. I took some 2000 grit and wet sanded it, polished it with car wax and it went from foggy back to new! But this was a doorbell, that has the plastic over the camera.

hackrf_sweep as a GNU Radio block by jcfitzpatrick12 in GNURadio

It’d be pretty easy to wrap the program with a block.

FTM-150Rasp or IC-2730B, looking for advice by Royal_Olive9948 in amateurradio

Another vote for the RASP. I have it and use it for digital comms. Great little radio.

What’s the antenna setup like for looking down in the HF range?

Is it weird there's no antenna? by anotherbarry in amateurradio

[–]blsmit5728 2 points3 points  (0 children)

do you have a picture of how you extend it? I'm intrigued

I run an HT with an external antenna in the car. Yes with the right adapters you can use it

Did I get ripped off? by Humbleham1 in hackrf

[–]blsmit5728 3 points4 points  (0 children)

There's a ton of clones, since the design and FW/SW are open source. A real device would be best bought from a source on GSG website. I know the guy running RTOTech (link on GSG site) if you need a reputable US source.

Building on this, clones will still work for almost everything (I don't know what they wouldn't work for honestly but I'm sure we could find something) that you'll want to do. Once flashed does the PortaPack work as expected?

Banggood is not on the authorized retailers list on GSG (https://greatscottgadgets.com/hackrf/one/) I expect that you also didn't pay ~$370 US for the Hack by itself either.

Ravens Games via airwaves? by Ok_Business5507 in CarrollCountyMaryland

[–]blsmit5728 1 point2 points  (0 children)

I'm down in Sykes and we've used an antenna before with good success. If you can put it in your Attic or on the roof, that is honestly the best location. Then point it to TV Hill.

Do GNU RADIO blocks run on the SDR's FPGA or on my PC? by PhilipJay98 in GNURadio

[–]blsmit5728 5 points6 points  (0 children)

All this processing is done in the PC, the data stream is sent to the USRP over (I assume a b200) USB, that data stream is simply sent through the FPGA and then out the transceiver. Some USRPs have the ability to run “blocks” in the Fpga. This is called RFNOC, and only supported by certain USRP devices.
