Got it. Thanks!

Re: RSP2 for radio astronomy

Cool idea - I remember back in the '90s setting up an impromptu "radio telescope" with my (college) radio club. We set up a shortwave receiver to listen at ~20.5MHz (if I recall correctly) when the comet Shoemaker-Levy-9 was going to impact Jupiter. We used a simple antenna - a wire dipole...

Re: Input impedance at UFL-R connector.

Good question. Because the characteristic/design input impedance needs to be reasonably well matched between the antenna and the filter, in order for the filter to do it's job with any degree of success.

Re: Copying digital modes with SDRuno

So I'm looking to use VAC to pipe "audio" [really just a bitstream] from SDRuno to FLdigi, WinPSK, Spectrum Lab, & etc for digital mode copy. In unix I would just pipe stuff from one application to another, but Winderz always makes things more complicated. I D/L'ed the current VAC soft...

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

For receive purposes only, 400/450 Ohm transmit rated parallel line is total overkill, and weighs much more than some of the alternatives - There are still supplies of the thinner, and thus lighter, 300-Ohn "TV Twinlead" available, and I highly recommend it for LF~VHF-Lo (50MHz) wire recei...

Re: SDRuno on Linux

Please allow me to second this request. I've been a licensed ham since 1991, have had my extra since 2000. Bought an Icom PCR-1500 in 2000 and expected way more than I got. Got bored with the hobby in about 2005 and took a 10 year break from doing much with radio, but did a number of things with com...

Re: Beverage or Wellbrook Loop?

If you have room for a 300 m Beverage don't hesitate. Build it! Of course it is highly directional. I do not have room for a Beverage, but my lousy 25 m "random" wire already outperforms both my 5 m and even my 14 m magnetic loop. But not in all directions, of course. The loops are better...

Re: Delta loop antenna - advice please...

Hello Mike, I apologize, but I'm going to answer your question with a few questions - What is your desired purpose for this antenna - do you want to receive mostly DX (stations roughly 750Km and further from you) , or are you mostly interested in signals which originate in your general area (less th...
