Re: No audio with CubicSDR on Raspberry Pi

Actually I have it sorted out now. I wasn't aware that I needed to click in the waterfall to create a "modem" and start receiving audio. CubicSDR is organized a little differently from other SDR software programs I've used, and I'll have to spend more time with it (and read the manual) to ...

No audio with CubicSDR on Raspberry Pi

Tonight I thought I'd try connecting my RSP2 to a Raspberry Pi 3 Model B running the CubicSDR software, installed per the instructions here: https://www.youtube.com/watch?v=WvcbnoaYnL8 The software appears to start fine and recognizes my RSP2, and I see signals on the waterfall. However, I get absol...

Re: How to connect a nevada EFW-1 to sdr play

Vk7jj, thanks very much for the links and information. As you point out, I'm barely scratching the surface in learning. I'll try those configurations and see what kind of results they produce.

Re: How to connect a nevada EFW-1 to sdr play

For the HF spectrum, I've had far better results attaching a somewhat similar end-fed wire antenna to the SDRplay's Hi Z port (the green high-impedance thingie) rather than to either of the other two antenna ports. As dave524 notes, the photos for the antenna you ordered appear to indicate that the ...

Re: Discone recommendations?

Update: Thinking I would try out a discone antenna while keeping the cost minimal, I ordered a Workman T-601 (~US$33) which arrived today. This is a relatively compact Taiwanese-made model that is marketed by at least a couple of companies (besides Workman, the identical antenna is also sold as the ...

Re: Discone recommendations?

Thanks for the thoughts. I suspect the shop staff was just trying to save me some money (lash something together, hear something) while I get my feet wet and see where my interests lie. Vk7jj, I've in fact found my end-fed wire to be pretty noisy in VHF, so I do see a discone in my near future. G1hb...

Re: Discone recommendations?

Thanks, I'll check out the coax loss calculator. I did actually bring this topic up with the local shop. Their advice was (a) I'm probably best off sticking with my end-fed long-wire antenna with a plain-wire lead-in across all bands up into VHF and beyond, and (b) coax is really only necessary for ...

Re: Discone recommendations?

Thanks for the information and the link, that looks pretty much like the examples I've seen online. Do you have any impressions on how the antenna's performance (for receiving only) is affected by the length of the lead-in coax? While I can probably work out mounting it fairly close to my receiver, ...

Discone recommendations?

After a week or so with my new SDRplay RSP2, I've been getting decent results in HF with an end-fed long-wire antenna. I've also ordered an active mini-whip to see how that compares. I'm now thinking about a general-purpose antenna for VHF and above, to be used at my home location on one of the SDRp...
