Looks like the 20M folks aren't going to be too happy this AM! ouch! 73 Kriss KA1GJU

That's an interesting article. Personally, my money is on this cycle being about the same or maybe 5-10% bigger than Cycle 24.. the "solar polar magnetic field at minimum" method

Before you place your bets, there are afew clues here.. the words New, Research and Predicts. Much the same asModelling …or Modeling depending on where you live, Guesswork andStochastic and worst

I just ran across something that is likely to make this situation a lot livelier. It might also end up with the amateur allocations being "sold" to broadcasters who suddenly need new

This is part 2 Using series and parallel addition of the loop coils we can extend the range from 140KHZ to 2000KHZ Also adding fixed capacitance to get down below the EU longwave

I'm a twit. I forgot that this group is effectively defunct. I'll go to the forum with my question. Sorry, John G4DRS

I use SDRC 3.0.25 as a panadapter, displaying the 9MHz IF of my FTdx5000. I use Logger32 as my logging software. SDRC is automatically launched when Logger32 starts up. Sometimes, maybe once in every

One more thumbs up for running Simon's software under Bootcamp on my 2020 MacBook Pro... it's extremely stable, uses minimal CPU and looks great :) I've use Macs for years at home and Windows-only

I use the LZ1AQ active loop. It's not tuned, but works really well. Sent from my Galaxy

A few comments to all that responded. There are not many varicap diodes withenough swing to tune the VLF band. Using two back-to-back 1SV149 diodes wouldgive me only 250pF so I’d need 8 to arrive

Another fun antenna to play with is the dielectric loaded flat spiral if you want to play at UHF for a REALLY broadband efficient antenna. I took an antennas class in college.

Have you to download and unpack zadig ? Zadig has more than one driver. One is suit for your rtl. Bert Verzonden vanaf mijn Galaxy -------- Oorspronkelijk bericht -------- Van: Jerry Lofstead

A big loop is probably best for RX performance, but has to be, well, BIG - and robustly built. The Maynard derivatives, especially the ultralight DX series (search uldx

Scott It would help if you named this device. And it might help if you said what driver/software was supplied with it. And maybe what actually happened when you tried. Alan

hello there i purchased one of thease this week from china,ive plugged it in to the pc it does not respond.. contacted the seller they sent me software what dont work,ive tried other sites with

I know this is an old thread but I'm running the latest version of Simon's excellent software under Bootcamp on an antique 2011 MacBook Pro. Runs great. I also have it running on my 2015 iMac. I've

My working levels came from a DoD receiver specification that was lying around. Take two signals into the receiver front end and vary their identical levels upwards until the 3rd order

The precise circuit used can make a lot of difference. Back to back diodes can perform much better than a single diode. It can also bend your head out of shape when you try to measure

Hi In my honest opinion.. Ferrite antennas are really down on sensitivity compared to tuned mag loops. ( tried it.) Useful for dfing..but no one uses them for low noise dx Rx antennas..there is a
