Dave, I am 79 and my wife is 77 and we are both Amateur Radio Operators and enjoy building antennas more than we do talking on HF. I have been building antennas since I was 14 and will never get over

Are there any transmit rated loops out there that are worth their salt? Thanks Grady

I'm reminded of when a friend and I were watching Norm Abrams build something absolutely beautiful like a trestle table with free lumber scavenged from a barn being torn down. She turned to me and

* Very similar to an issue I have here, does it sound like a whirring noise if you listen to it? Mine runs for perhaps 20 minutes then 'has a rest' and may restart after 10 minutes or often longer. *

Ah just saw that part. Is it on / off at the same time every day (on a time switch), or does it vary with the weather (Solar PV,? street lamps, heating system) ?

Hi Chris, It's typical of a switched mode power supply, which looks to have an approximate 9KHz component. Maybe a car or mobility scooter charger or Solar PV invertor (if it doesn't go off at night

10 January 2022 Only daylight hours, AFAIK, and MUCH louder on a big (about 380 feet in circumference) horizontal quad wire loop that along one leg runs parallel to overhead phone and mains LV power

Hi Gary, If you want to try for yourself take a look at the many KiWi web sdr's that are available free on-line. http://rx.linkfanel.net/ Software such as SDR Sharp does give an indication of received

Personally I wouldn't. If you look at the amplifier input impedance measurements in the files section /g/loopantennas/files/Loop%20Amp%20Tests%20by%20AA7U You will see that the W6LVP

Hi Garey, This guy has a lot of good explainer videos on youtube. Here's one about the waterfall display - https://www.youtube.com/watch?v=91XtLZNIyK8 Danny UK.

This is a common theme in amateur radio circles too, if you have ever been to a hamfest or similar you will often hear "I could make one of those for a fraction of the price". Amateur constructors,

You are still not getting it Dave, despite having business practices explained to you more than once. You have certainly not factored in your own costs in getting educated through to the point where

Hi Zulu-Romeo. I wonder if you have compared the eBay loop amplifier (M0AYF circuit) to any other loop amplifiers in an A/B test? I have, and found it to compare quite well above 2MHz. But on LF and

Dave, Maybe you would like to share the schematic for your $20 loop amp with the group, so those that are builders can build one for their use. Everett N4CY Sent from the all new AOL app for iOS

Well, me too. But my point was that, at least here at my location, the design is working better

Never used a SDR -? just learning about them, as I watch these discussions.? I understand seeing signals across a freq range all at one time ( spectrum of frequencies ), but what does a "water fall"

The ALA1530LN should cope, but you may need some Rx attenuation or drop the AM station into the loops null. 73 Andrew Sent: Monday, January 10, 2022 12:17 AM To: [email protected] Subject: Re:

Thanks for the info Andrew. Would 3 miles from a 1500 watt AM broadcast station be too close? Ryan W6ZAR

Dave, How do you test your 50 Buck loop amplifier and what performance parameters does it have? 73 Andrew G8LUG _._,_._,_

I've been fortunate to be able to have the means to support others in the hobby when they build stuff to try and supplement their income. For one, I'm single. :^) I recently bought the new version of
