Re: Discone recommendations?

Good on you; sometimes asking creates a problem, quot capita tot sensus and I shudder to think of all the opinions being roused right now amongst this readership, the antenna topic is endless. a) any appreciable length of end fed wire is going to be a very noisy antenna. I've never ever tamed one an...

Re: Discone recommendations?

The easiest thing is to work out in your own mind the best compromise between the cost of various grades of coax and connectors V's the signal loss at the frequencies you are interested in over the length of the coax run. There are lots of online coax loss calculators that work the loss out for you,...

Re: Discone recommendations?

I have two, both different brands and sourced two years apart, yet are both identical. They look exactly the same as 90% of those I've seen at fellow ham shacks, they all look like this: http://www.ebay.com/itm/SIRIO-SD-1300-Discone-Antenna-25-MHz-1-3-GHz-N-Connector-/302424956113 As per the advert ...

Re: Balun needed for coax fed dipole on hi-z port?

Hi Chuck, I wanted to commend your reply in particular The difference a good balun makes can be profound - as much as 20~30dB reduction in noise It sure can and it's a thrill to achieve such an improvement cheaply and easily. The word "balun" can cause confusion so I thought the simplest t...

Re: Long-wire performance on different ports, bands

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? The block diagram of the RSP2 shows the LNA is permanently in circuit when using Ports A and B and the only user adjustment is ga...

Re: SDRUno will not work on VMWare FUsion

I know I'm late to this and you may have given up or fixed it. I solved that problem by setting the SDRPlay as a USB2 device in VMWare. (BTW I'm using an RSP2) VMWare Menu: Virtual Machine > Settings... > USB & Bluetooth > [click on the SDRPlay device] > Advanced (the tiny down arrow) > USB Comp...

Re: Which Windows 10 SDR Software(s) Work with the RSP2?

Have you tried SDR-Console V3 preview? It's a very nice app and Windows 10 is the author's preference OS. It's user interface provides easy and intuitive adjustment of frequency and waterfall zoom, if that's what you're referring to, though everything takes time for it's best bits to sink in and be ...

Re: SDRplay Notebook interference

Well called DanubeBCL :-)

Great to see a straightforward fix, getting rid of noise and lowering the rx noise floor sometimes becomes a never ending quest.
