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...

I see from a tutorial video that SDRUno's main panel for the RSP1 has a prominent button for LNA. But I'm not finding it in SDRUno for RSP2. Has it been moved somewhere?

Re: Long-wire performance on different ports, bands

Thanks for the suggestion. Initially I didn't see an AGC toggle in SDRUno's main panel, and no mention of it in the manual, but after clicking a button marked "SETT." a new window opened with a check box for IF AGC -- I assume that's it? I unchecked the box which caused a gain slider to ap...
