Re: Power connection question

Yeah I saw that... But just to clarify we never intended to fully implement USB-C in the first place. Our PCB designer noted that his intention was to use the USB-C connector, simply because it's physically stronger (with through hole strain relief - there are NO microUSB connectors with through hol...

Re: Debugging a single SDR

Did you edit the EEPROMs recently? Maybe the fourth EEPROM was corrupted?

Re: What (besides sw compatibility) is needed for SDR?

An SDR at it's very core is an analog to digital converter (ADC). So it needs this ADC hardware to be classed as an SDR. Standard radios don't use ADCs, they use standard analogue components to process the radio signals into audio. They can be computer controlled, but the RF signal is never digitize...

Re: SDR radio kits to assemble?

There's various ham radio SDR kits, like the Softrock, mcHF etc http://fivedash.com/ http://www.m0nka.co.uk/ One interesting one might be the Hermes Lite II http://www.hermeslite.com/. You'd probably need to purchase your own parts, or wait for a group buy though. SMT isn't too hard to hand solder i...

Re: OT entries in the Sigidwiki

Thanks for checking. The MFJ one, I don't think it's spam. He's just showing what signal it emits as part of it's measurement features which might be interesting to some, as it provides insight on how it's doing it. The UHF morse shouldn't be in the Identified signal category, he should have at the ...

Re: Debugging a single SDR

The reading of the 3 devices looks strange too. It should display a SN and name.

Can you try seeing if one unit at a time works? Did anything else in your setup change?

Re: Strange USB problems

To confirm, it's working normally with the 80cm cable, just not with the 3M one?

3M might unfortunately be too long to sustain such a high data rate.

Re: Kerberos Shipping ETA

Factory says they'll ready to ship by Mid-August. I think that will be fairly accurate.

Re: rtlsdr v3 + raspberry 3 + powerbank

The largest one that you can find, but make absolutely sure that the powerbank is capable or supplying 3A or more. The Pi3 needs at least 3A.

Re: R820T3 ?

Interesting find, i'll look into it. My guess is that because they've stopped selling the R820T2 for normal TV tuners, and it's mostly used for SDR now, they're just calling it the R820T3. Remember the only difference between the R820T and R820T2 was the place they were manufactured at, and the sili...
