To: main@UltralightDX.groups.io Subject: Found u 😋
  Sent from Mail for Windows 10  Glad i found the group again .I've been away for a few years ,but I've been busy at times fooling around with various FSL and other antenna"s. Since I was last here I have built 5 FSL loop's, Because of the lack of Ferrite over time 2 of those have sacrificed their parts to build other loop"s.
The largest loop ( 8 inch red Litz ) Tunes from 150-1700 Khz. with some vodoo from several fixed capsÂ
and a gang switch ,😋 The middle loop (blue litz ) is just for MW freqs. The small loop (3 inch blue litz) tunes from about 250- 1710 Khz
At the moment I'm working on a new design involving Ferrite rods ,And using a very high Q capacitor .I finished the mock-up phase and did a little testing yesterday AM ,I found some interesting results ,More on this later at some point.
Several years ago Steve Ratslaff (sry spelling) and I , talked back and forth ,at the time I was building the biggest loop ,and he gave my great advice to achieve my objective ,of course over time I've lost his e.mail etc . Â
Hope he is still around ?
Just finished watching Gary's Convention speech I hope there will be a Part 2 ?
Glad to be back in the loop 😋Â
Thanks Gary ,,,,,,,All

hi Would it be feasible to upgrade small commercial loops like the Select A Tenna, Terk AM-1000(Advantage) & the Tecsun/Kaito AN 100/AN 200 by placing short rods around the circumference On Sat, Oct 26, 2019 at 7:44 PM dean wayman <dx_plains@...> wrote:

Good to see your images, Dean!
The range 150-1700kHz raises a query: how well do they work a bit higher, ie for reception of amateur/ham signals in the 16m band? In urban areas, interference levels can be so high as to thwart working on 160m. Using a "regular" dipole for tx and a remote FSL for receive might be an option. A magloop can do this, but needs to be quite large. Although heavy, a FSL might offer greater feasibility - if if works :-) Michael On 27/10/2019 02:41, dean wayman wrote: ......

Hi:
Phil , as a matter of fact that was going to be my next experiment I have the AN 200 that i can sacrifice . hopefully soon I'll get to it ? Dean |

Hi Michael :
At this point I'd be just guessing,all my building has been focused on MW and below ,, but it should be possible to make a FSL that tunes those freq"s? Surely some one else has more experience here . Dean |

Not something I have done but keen to see how it works out. Paul On Mon, Oct 28, 2019 at 11:44 AM Dean wayman <dx_plains@...> wrote: Hi Michael : -- Paul

I assume the main issue would be performance at 160m of ferrite
rods nominally designed for lower BC frequencies. It would be interesting to know if anyone has tried it. I had an offer of ferrites some time back, but my pocket-money fell woely short of the asking price :-) Michael ......................................
