I was a member of this group some time ago... somehow I became disconnected but the daily message content continued to be delivered to my e-mail address. While continuing to read the mail, I was

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

Here is a synopsis of messages I recently received from Andy Ikin, they're pretty interesting and put to rest several questions that people have about the ALA-1530. I stand corrected on the loop

Oops: wouldn't be a 2f range anyway, forgot the sqrt. Should read "... this will not be a 1.4f frequency range but will be a 0 - C/2 top range with considerable overlap with the 0 - C single-section

But with a lot of not very useful overlap. A better way, with one less switch, would be to - wire the first section across the loop, - parallel the second section with 280pF and connect via a switch

Since the rotors are very likely on a common metal shaft, probably you cannot connect more than 2 sections in series. Much depends on how big your loop is and what frequencies you want to tune, which

Thanks Nigel and Jim, you both clarified for me what I need to do. I am just a novice and am learning as I go. Ed Dawson
