148 ft wire testing
|
raimo
Hi All.
I made 148 feet wire test last weekend. FC40 is abt 10 ft from ground, 119 wire first straight up 20 feets, to highest point at 30 feets, after that horisontal and straight until it ends at 20 ft height. Radio FT897 and FC40. Just fast test: tune or not.. 1810 to 2000 kHz: Tuned 3500 to 3740 kHz: No Tune 3745 to 3800 kHz: Tuned 7000 to 7200 kHz: Tuned 10100 to 10150 kHz: Tuned 14000 to 14350 kHz: No Tune 18068 to 18168 kHz: Tuned 21000 to 21450 kHz: Tuned 24890 to 24990 kHz: Tuned 28000 to 29700 kHz: Tuned 50000 to 52000 kHz: Tuned 73s es gl de rami, oh6bi |

119 wire first ... should be 148 wire. --- In YaesuTuner@..., "raimo" <oh6bi@...> wrote:

Hi All.
I copy here a messge I wrote in another group, maybe it is intresting also here : ' ' ' Hi BoB and All. Thanks. Yes I have somtimes red those stories, this 90 meters is new to me. There is plenty of info, but mainly idea with these kind of tuners is that operator has to know what he is trying. As well as normal dipoles etc. These are not any magic boxes, just simple LC tuners. (with CPU and other clewer stuff) This morning here in Vaasa area temp was minus 2 celsius, needed to skratch ice from windscreen, the sea is getting soon ice cover and not so much time anymore at summercottage. I already brought some radios to town and next random wire tests starts again in May. Next eperiment with FC40/FT897 is "original" windom with single line feeder. I made original windom some yaears ago with AH3/IC706 and that was working very well. Hopefully I get this tested next weekend. My target with all these testings is to find good travelling wires, so that I dont need to use time to search the lenghts. At "permanent" QTHs it is different, as I have had some antennas many years in same place.. 73 se GL QRP DX de rami, oh6bi --- In CW-Code-Warriors@..., MAXXOUT2@... wrote:

Try making the wire 145 foot, look at the AH-4 Graphical Length Wire Calculator in the Files Section here in this group.

Doesn't matter if the tuner is Icom or Yaesu, you still have to avoid 1/2 wavelength for the wire antenna. --- In YaesuTuner@..., "raimo" <oh6bi@...> wrote:
