Not easily done. Loops are inherently low impedance antennas, and when you're well below the first resonance they look a lot like an inductor. As you approach the resonance, they begin to look like a

I wish I could find a simple design for a SWL loop antenna that would cover, at least, say, between 5 and 10 MHz. Just something simple I could stick up in the yard, maybe. All these amplifiers,

Hi Len, You are correct on all counts. The original purpose of the arrangement was to provide a decent antenna for my SWL activity (Sony 7600 receiver) from 5mhz to 15mhz. The tuner sits inside the

Does this mean there is no capacitor attached to the loop and all tuning is done by the ATU? So the resistance of the feeder is included in the loop resonance? If so, you could get higher Q and hence

Hey Everyone, Excuses for those who saw this message as well on the Shortwave-SWL-Antenna group; someone posted off list about this list to me, so I just signed up here! Who here has built a WL1030

Jim, I don't even have to go out to the patio to make adjustments as my loop is mounted indoors where it picks up just as much noise as my whip antenna (36") and actually is capable of discriminating

I am building the contol boxes for the K9AY Loop and am using the FAR Circuits boards. I would love to hear from anyone who has built them 73 John NS5Z

Automatic tuning could be made to work, but you will have to furnish a pilot carrier for the coupler to know how to tune the loop. The SGC "stealth kit" is basicly a green camouflaged loop and support

Yes, it is certainly possible. ATU's are primarily designed to tune 2-30 mhz and go into the auto tune mode when they receive an injection of several watts of power from your xmitter. The larger the

Hi, An automatic antenna tuner works matching the transmitted signal of the transmitter to the antenna. If you are using it for this purpose it will work well. I am using an LDG AT-200Pro autotuner

Hi, loop fans! I'm thinking of using an auto antenna tuner to match a HF square loop's internal impetance with RG58. Is that possible? Thanks in advance...

Hi Fraser, I'll give them a try and see what's still available. I had already ordered the "2nd half of the 90's" CD from the Medium Wave Journal, which should include several of Andy's articles.

Damn, Yahoo Groups Email address detector has hidden the email addresses in my message. Here they are again but I've used AT instead of @ so you will need to change the email address accordingly

Hi Rob, Shortwave Magazine became part of Radio User magazine which is a PW Publishing product. Since the change it has not been very clear on the website how you get copies of older SWM articles. You

Hi John, Unfortunately, there doesn't seem to be a way to order individual articles (or even entire back issues) from SHortwave (Wireless?) magazine when I looked on their website. Do you have a

Hello Rob et al Andy Ikin did write a number of articles, as listed below. There may have been more. A. Ikin, Active solution?, Short Wave Magazine, Oct 1996, pp 22, 23, 23 36 A. Ikin, Intermodulation

Shucks!... All Andy did was repeat the info that is on his ALA1530 web page. Take that bit and some study of Dallas Lankford's material at... <http://www.kongsfjord.no/> Hmmm... certainly not out of

Hi Nigel, At least, as I said before I don't have to "operate" on the Aluminum. I'm glad I held off for a few days thinking about it. Mea culpa! Andy's a good guy and I understand why he doesn't want
