Well, what most don't seem to realize is that this push for "wideband" data is coming mostly from yachtsmen who want a service in the amateur bands to avoid the cost ot wideband marine data services
That should work fine, Gary! You would have around 3 dB loss in a two-way splitter + a SMALL amount of mismatch-loss for the 50-75 ohm mismatch. I would expect that if your radio will work with the b
One word of caution, Gary, if the CATV splitter is a transformer type, rather than resistive it may of have enough low-frequency response for 160 m! Check around with RS and your local electronics st
Yeah, that's why I cautioned Gary about using CATV splitters at 160m. Seems that he has enough reserve gain with his Beverage and K3, that he could certainly tolerate the loss of a 50 ohm resistive s
Well, that is exactly what it's all about, Dan!! Some of us need to press those points really hard with FCC and ARRL! They are trying to usurp our amateur spectrum for commercial and monetary purpose
?? A big vertical is omni directional and has high signal levels. This is in contrast to the beverage which has low signal levels and tries to null out certain directions. If I disconnect the vertica
Hi, Mike Could you add 1 or 2 top wires and turn it into an inverted-L or Tee for topband? Or you could add an 80m trap at the top followed by enough horizontal (or sloped) wire to resonate on 160, w
Good morning/good afternoon, Andrzej! How kind and thoughtful of you to inquire about my; health!! I'm OK, but I do have some multiple sclerosis that slows me down a bit, but it's doing much better t
Thanks, Ed! Yes, Andy is a prince - and a great guy! Really heartwarming to have someone on the "other side of the pond" checking on me! Well, my MS is MUCH better than it was last summer! Some of th
So true! I'm relieved, though, that Bob's suffering has come to an end and that he's in a better place! 73 - Rest in peace, Bob! Charlie, K4OTV What a loss. Early mornings will never be the same. RIP

I agree with all those points, Jim! Over the years, professionally, we designed many Fair-Rite, cores into most of our electricity, gas and water meter and electricity load-management products and sh
Well, I don't think there is a "one-size" or "one--mix" "fits all" preferred solution. I've wanted to try some 31 mix cores for common-mode isolation at 80 and 160. On the other hand, some of the Fai
I've mostly used 73 mix tubular and binocular Fair-Rite cores of all sorts of common-mode chokes on coax and for matching transformers 160/80m receiving loops and for input match to my 3-500ZG amp. H

Great write-up! Charlie, K4OTV Finding many references to the 2009 Chesterfield TX3A ability to hear well, I decided to check it out. Found a very interesting write up by AA7JV. It was definitely a b
Amen!! 73, Charlie, K4OTV Alex, I much imagine a similar statement was uttered many years ago when the first use of AM transmitters came into use and probably again when SSB came into use. Its not th

Doesn't help you HEAR any better! Generally, on top band, even with my modest inverted- L with a few elevated radials, if could hear 'em I could work 'em! With 500 W. Best thing I ever did for myself
